Causes You can become dehydrated if you lose too much fluid, do not drink enough water or fluids, or both. Your body may lose a lot of fluid from: Sweating too much, for example, from exercising in hot weather Fever Vomiting or diarrhea Urinating too much uncontrolled diabetes or some medicines, like diuretics, can cause you to urinate a lot You might not drink enough fluids because: You do not feel like eating or drinking because you are sick You are nauseated You have a sore throat or mouth sores Older adults and people with certain diseases, such as diabetes, are also at higher risk for dehydration.

Symptoms Signs of mild to moderate dehydration include: Thirst Dry or sticky mouth Not urinating much Darker yellow urine Dry, cool skin Headache Muscle cramps Signs of severe dehydration include: Not urinating, or very dark yellow or amber-colored urine Dry, shriveled skin Irritability or confusion Dizziness or lightheadedness Rapid heartbeat Rapid breathing Sunken eyes Listlessness Shock not enough blood flow through the body Unconsciousness or delirium.

Exams and Tests Your health care provider will look for these signs of dehydration: Low blood pressure. Blood pressure that drops when you stand up after lying down. White finger tips that do not return to a pink color after your provider presses the fingertip.

Skin that is not as elastic as normal. When the provider pinches it into a fold, it may slowly sag back into place.

Normally, skin springs back right away. Rapid heart rate. Your provider may do lab tests such as: Blood tests to check kidney function Urine tests to see what may be causing dehydration Other tests to see what may be causing dehydration blood sugar test for diabetes.

Treatment To treat dehydration: Try sipping water or sucking on ice cubes. Try drinking water or sports drinks that contain electrolytes. Do not take salt tablets.

They can cause serious complications. Ask your provider what you should eat if you have diarrhea. Outlook Prognosis If you notice signs of dehydration and treat it quickly, you should recover completely.

Possible Complications Untreated severe dehydration may cause: Death Permanent brain damage Seizures. When to Contact a Medical Professional You should call or the local emergency number if: The person loses consciousness at any time. There is any other change in the person's alertness for example, confusion or seizures.

The person has a fever over °F You notice symptoms of heatstroke such as rapid pulse or rapid breathing. The person's condition does not improve or gets worse despite treatment. Prevention To prevent dehydration: Drink plenty of fluids every day, even when you are well. Drink more when the weather is hot or you are exercising.

If anyone in your family is ill, pay attention to how much they are able to drink. Pay close attention to children and older adults.

Anyone with a fever, vomiting, or diarrhea should drink plenty of fluids. DO NOT wait for signs of dehydration. If you think you or someone in your family may become dehydrated, call your provider.

Do this before the person becomes dehydrated. References Kenefick RW, Cheuvront SN, Leon LR, O'Brien KK. Find a Doctor Request an Appointment. close ×.

: Signs of dehydration

How Can You Tell If You’re Dehydrated?

As the patient is being resuscitated, clinical and laboratory examination must focus on the discovery and correction of the cause of dehydration. The principle differential of dehydration in adults is the loss of body water versus the loss of blood.

This is important because blood loss should be replaced with blood, while water loss should be replaced with fluid. The next point to consider is the differential diagnosis of the cause of dehydration, as discussed under etiology.

When the underlying cause of dehydration is treated, and the patient's volume has been restored, the majority of patients recover fully. Failure to treat dehydration in older adults may lead to significant mortality. Complications of dehydration occur due to inadequate fluid replacement and over-aggressive fluid replacement.

Complications of under-resuscitation are due to hypoperfusion of vital organs and complications due to renal efforts to retain fluid.

Altered mental status, renal failure, shock liver, lactic acidosis, hypotension, and death are related to organ-hypoperfusion.

Fluid and electrolyte abnormalities such as uremia, hyponatremia, hypernatremia, hypokalemia, hyperkalemia, metabolic acidosis, and metabolic alkalosis may occur. Excess fluid administration to correct dehydration may cause peripheral edema and pulmonary edema. In patients with severe hyponatremia, volume correction may cause a rapid rise in sodium, which can cause central pontine myelinolysis.

Renal consultation will be needed at times, especially with severe hyponatremia, but in most cases, the treating clinician can evaluate and correct dehydration. Although the CDC does not have defined water intake recommendations, adults are encouraged to maintain between L per day.

For example, marathon runners water should drink more than a nonmobile person. In elderly patients, excessive free water drinking can cause hyponatremia, so balanced hydration solutions are recommended. Often because water intake is not the most pressing topic for the average clinical visit, it is often overlooked regarding patient care.

If we can encourage more healthy lifestyle choices and daily hydration, it can lead to decreased morbidity, mortality, and complications associated with dehydration. Healthcare providers should look toward implementing more incentives and initiatives toward increasing hydration amongst staff and patient populations.

Continuing Education Activity Dehydration is a common condition that affects patients of all ages. Etiology Body water is lost through the skin, lungs, kidneys, and GI tract. The source of water loss may also understand the etiologies of dehydration: Failure to replace water loss: altered mentation, immobility, impaired thirst mechanism, drug overdose leading to coma.

Excess water loss from the kidney: medications such as diuretics, acute and chronic renal disease, post-obstructive diuresis, salt-wasting tubular disease, Addison disease, hypoaldosteronism, hyperglycemia. Excess water loss from the GI tract: vomiting, diarrhea, laxatives, gastric suctioning, fistulas.

Excess insensible loss: sepsis, medications, hyperthyroidism, asthma, chronic obstructive pulmonary disease COPD , drugs. Epidemiology There is no recent data on rates of dehydration in the general population, but we do know much of the epidemiology of dehydration in adults.

Pathophysiology Water plays a key role in maintaining multiple physiological functions within the body. History and Physical Hypovolemic patients can present with a wide assortment of symptoms and physical exam findings.

Evaluation There is no gold standard test for dehydration. Differential Diagnosis The principle differential of dehydration in adults is the loss of body water versus the loss of blood. Prognosis When the underlying cause of dehydration is treated, and the patient's volume has been restored, the majority of patients recover fully.

Complications Complications of dehydration occur due to inadequate fluid replacement and over-aggressive fluid replacement. Consultations Renal consultation will be needed at times, especially with severe hyponatremia, but in most cases, the treating clinician can evaluate and correct dehydration.

Deterrence and Patient Education Although the CDC does not have defined water intake recommendations, adults are encouraged to maintain between L per day. Pearls and Other Issues Dehydration is common in elderly patients and with certain diseases.

Because adequate volume is essential to the peak function of the human body, there are multiple mechanisms to achieve and maintain euvolemia. The diagnosis of volume depletion depends on the careful assessment of physical exam, history, and laboratory tests. There is no one test to diagnose dehydration.

The first goal of treatment of dehydration is to restore circulating volume. The second goal is to find the cause of the dehydration so that it will not recur. In patients with normal heart and renal function, liberal fluid may be given to restore volume quickly. This is best accomplished with small volumes given quickly, followed by immediate reassessment and redosing as needed.

In severe hyponatremia, rapid correction of volume deficits may cause a sharp rise in the serum sodium that can cause central pontine myelinolysis CPM. The clinician must assess the risks and benefits of rapid volume repletion versus the risk of CPM. In all cases, the volume status and sodium levels must be monitored closely.

Factors contributing to dehydration in nursing homes: inadequate staffing and lack of professional supervision. J Am Geriatr Soc. Dehydration is a condition where the body does not have enough water to properly function. In most cases it can be avoided by increasing water intake.

Dehydration is caused primarily by sweating too much which is commonly brought on by exercising in hot weather. Other causes include fever, vomiting, diarrhea, and too frequent urination. People who drink an insufficient amount of fluids can also get dehydrated.

They may not drink enough because of stomach irritation from sickness, nausea, or a sore throat. People who have a heart condition, are seeking cardiology services at a heart center, are overweight, have kidney problems, have diabetes, are under the age of two, or over the age of 50 are more prone to dehydration and should pay extra attention to water consumption.

A thirsty person is a dehydrated person. Dry mouth also frequently accompanies thirst. So if you are feeling thirsty or have dry mouth take it as a sign you need to drink some water.

When your body is dehydrated it compensates by constricting blood vessels and increasing the heart rate to maintain constant blood pressure. The body also redirects blood away from skin to internal organs like the brain and lungs. However, this defense will begin to fail as dehydration worsens.

Symptoms like lightheadedness, muscle cramps, and general weakness are indications that the body is failing to compensate for dehydration.

Nausea and vomiting are particularly bad because they can cause the situation to get worse. mail economy-ni. For queries or advice about passports, contact HM Passport Office.

Severe, acute diarrhea — that is, diarrhea that comes on suddenly and violently — can cause a tremendous loss of water and electrolytes in a short amount of time.

If you have vomiting along with diarrhea, you lose even more fluids and minerals. In general, the higher your fever, the more dehydrated you may become. The problem worsens if you have a fever in addition to diarrhea and vomiting. Excessive sweating.

You lose water when you sweat. If you do vigorous activity and don't replace fluids as you go along, you can become dehydrated. Hot, humid weather increases the amount you sweat and the amount of fluid you lose.

Increased urination. This may be due to undiagnosed or uncontrolled diabetes. Certain medications, such as diuretics and some blood pressure medications, also can lead to dehydration, generally because they cause you to urinate more.

Anyone can become dehydrated, but certain people are at greater risk: Infants and children. The most likely group to experience severe diarrhea and vomiting, infants and children are especially vulnerable to dehydration.

Having a higher surface area to volume area, they also lose a higher proportion of their fluids from a high fever or burns. Young children often can't tell you that they're thirsty, nor can they get a drink for themselves.

Older adults. As you age, your body's fluid reserve becomes smaller, your ability to conserve water is reduced and your thirst sense becomes less acute.

These problems are compounded by chronic illnesses such as diabetes and dementia, and by the use of certain medications. Older adults also may have mobility problems that limit their ability to obtain water for themselves.

People with chronic illnesses. Having uncontrolled or untreated diabetes puts you at high risk of dehydration. Kidney disease also increases your risk, as do medications that increase urination.

Even having a cold or sore throat makes you more susceptible to dehydration because you're less likely to feel like eating or drinking when you're sick. People who work or exercise outside. When it's hot and humid, your risk of dehydration and heat illness increases.

That's because when the air is humid, sweat can't evaporate and cool you as quickly as it normally does, and this can lead to an increased body temperature and the need for more fluids. Dehydration can lead to serious complications, including: Heat injury.

If you don't drink enough fluids when you're exercising vigorously and perspiring heavily, you may end up with a heat injury, ranging in severity from mild heat cramps to heat exhaustion or potentially life-threatening heatstroke.

Urinary and kidney problems. Prolonged or repeated bouts of dehydration can cause urinary tract infections, kidney stones and even kidney failure. Electrolytes — such as potassium and sodium — help carry electrical signals from cell to cell.

If your electrolytes are out of balance, the normal electrical messages can become mixed up, which can lead to involuntary muscle contractions and sometimes to a loss of consciousness.

Low blood volume shock hypovolemic shock. This is one of the most serious, and sometimes life-threatening, complications of dehydration. It occurs when low blood volume causes a drop in blood pressure and a drop in the amount of oxygen in your body.

People may need to take in more fluids if they are experiencing conditions such as: Vomiting or diarrhea. If your child is vomiting or has diarrhea, start giving extra water or an oral rehydration solution at the first signs of illness.

Don't wait until dehydration occurs. Strenuous exercise. In general, it's best to start hydrating the day before strenuous exercise. Producing lots of clear, dilute urine is a good indication that you're well-hydrated.

During the activity, replenish fluids at regular intervals and continue drinking water or other fluids after you're finished. Hot or cold weather. You need to drink additional water in hot or humid weather to help lower your body temperature and to replace what you lose through sweating.

You may also need extra water in cold weather to combat moisture loss from dry air, particularly at higher altitudes Illness.

Older adults most commonly become dehydrated during minor illnesses — such as influenza, bronchitis or bladder infections. Make sure to drink extra fluids when you're not feeling well.

Treatment of hypovolemia dehydration in children. And sweating, peeing, vomiting, and diarrhea all militate against optimal fluid levels, says MedlinePlus , even to the point of threatening survival.

The feeling of thirst is the result of a complex physiological process, research shows , intended as a warning that you're dehydrated, and in danger of not functioning properly. As MedlinePlus points out, certain health conditions, including diabetes, can put you at an increased risk of dehydration.

People who are especially vulnerable to dehydration include those who are unable to quench their thirst because of disability or disease, athletes, and those who are simply too young or too old to replace lost fluids on their own, according to NHS Inform.

Men who are middle-aged or elderly may be at particular risk of complications from dehydration, according to a small study published in the Journal of Physiology in November The study did not involve women. The researchers found that over time, the body becomes worse at detecting markers of dehydration such as high levels of salt in the blood , and without these signals, older adults may not realize they are dehydrated or drink fluids to rehydrate.

Untreated dehydration can cause the heart rate to increase, straining your ticker. Extreme dehydration — defined by the World Health Organization as a loss of more than 10 percent of your body weight in fluid — can lead to injury or fatal complications, and it requires an ER visit.

Seizures, cardiac arrhythmia , or hypovolemic shock can occur because your blood volume is too low. Yet it rarely comes to that. Most of the time, you can easily replenish your fluid stores and fend off dehydration when you drink water throughout the day. Here are six surprising signs and symptoms of dehydration.

Saliva has antibacterial properties, but dehydration can prevent your body from making enough saliva, per the Better Health Channel. Johnson General Hospital. So the next time you experience dry mouth and your breath smells less than fresh, it may be time to rehydrate.

Higgins says, adding that skin may appear flushed as well. Another key skin-related symptom of dehydration is a loss of skin elasticity, according to MedlinePlus. One symptom to watch for is muscle cramps, which can happen during exercise, particularly in hot weather.

As the muscles work harder and harder, they can seize up from the heat itself. Bear in mind that when it comes to rehydration after exercise, all drinks may not be created equal.

A study published in March in BMJ Open Sport and Exercise Medicine found that when participants rehydrated with a drink containing electrolytes after exercise, they were less likely to develop muscle cramps. Participants who drank plain water, on the other hand, were more likely to have cramps.

The study was small, so its findings may not apply to you, but the next time you feel a muscle cramp coming on after exercise, opt for an electrolyte-filled sports drink. Higgins says symptoms may be milder or come on slower, but dehydration carries the same risks, regardless of the temperature outside.

Other symptoms of heat illness include fever and chills. Excessive sweating combined with your skin feeling cool to the touch may be signs of heat exhaustion, according to the Centers for Disease Control and Prevention CDC. Fever can worsen dehydration. The higher the fever, the more severely dehydrated you may become.

Unless your body temperature decreases, your skin will lose its cool clamminess and then become hot, flushed, and dry to the touch. Applying ice and cool, wet cloths, and moving to a cool area are short-term strategies until you can get medical attention.

According to the Mayo Clinic , children and infants lose more of their body fluid to fever, and they are more likely to experience severe diarrhea and vomiting from illness. An infant or young child may also have other dehydration-related symptoms, such as a soft spot on their head, no tears when they cry, or fewer wet diapers than normal.

Any fever in an infant or toddler is cause for concern. Ask your pediatrician for advice on when to call the doctor in these circumstances. The CDC urges adults with fever to seek help if their temperature reaches degrees F.

This could be a medical emergency. While you can crave anything from chocolate to a salty snack, cravings for sweets are more common because your body may be experiencing difficulty breaking down glycogen to release glucose into the bloodstream to use as fuel, he says.

As MedlinePlus points out, even mild dehydration can cause a headache. Although various factors besides dehydration can cause headaches, drinking a full glass of water and continuing to sip more fluids during the day is an easy way to ease your pain if, in fact, dehydration is the culprit.

Here are two other ways to check your hydration. Try this skin test. Use two fingers to pinch up some skin on the back of your hand, and then let go. The skin should spring back to its normal position in less than a couple of seconds.

Higgins says that if the skin returns to normal more slowly, you might be dehydrated, per MedlinePlus.

You can become dehydrated because of: Diarrhea Vomiting Sweating too much Urinating too much, which can happen because of certain medicines and illnesses Fever Not drinking enough water or other fluids Who is more likely to develop dehydration?

Certain people are more likely to develop dehydration: Older adults. Some people lose their sense of thirst as they age, so they don't drink enough fluids.

Infants and young children, who are more likely to have diarrhea or vomiting People with chronic illnesses that cause them to urinate or sweat more often, such as diabetes , cystic fibrosis , or kidney problems People who take medicines that cause them to urinate or sweat more People who exercise or work outdoors during hot weather What are the symptoms of dehydration?

In adults , the symptoms of dehydration include: Feeling very thirsty Dry mouth Urinating and sweating less than usual Dark-colored urine Dry skin Feeling tired Dizziness In infants and young children , the symptoms of dehydration include: Dry mouth and tongue Crying without tears No wet diapers for 3 hours or more A high fever Being unusually sleepy or drowsy Irritability Eyes that look sunken Dehydration can be mild, or it can be severe enough to be life-threatening.

Get medical help right away if the symptoms also include: Confusion Fainting Lack of urination Rapid heartbeat Rapid breathing Shock How is dehydration diagnosed? To find out if you dehydration, your health care provider will: Do a physical exam Check your vital signs Ask about your symptoms Your provider may also order tests, such as: Blood tests to check your electrolyte levels, especially potassium and sodium.

Electrolytes are minerals in your body that have an electric charge. They have many important jobs, including helping to keep a balance of fluids in your body. Blood tests to check your kidney function. Urine tests to check for dehydration and its cause.

What are the treatments for dehydration? Severe cases may be treated with intravenous IV fluids with salt in a hospital. Can dehydration be prevented? The key to preventing dehydration is making sure that you get enough fluids: Drink enough water every day.

Each person's needs can be different, so ask your health care provider how much you should be drinking each day. Avoid drinks that have sugar and caffeine. Drink extra fluids when the weather is hot, especially if you are exercising or working outside.

If you are losing a lot of minerals in sweat, sports drinks can help you. But some sports drinks have lots of sugar, so be careful not to drink too much of them. Get extra fluids when you are sick.

If you are having trouble keeping liquids down, you can try taking small sips of water or sucking on ice chips. Start Here. Dehydration Mayo Foundation for Medical Education and Research Also in Spanish Dehydration For Parents Nemours Foundation Also in Spanish.

Access free multiple choice questions on this topic. While this is not supported by medical literature, dehydration is common in elderly patients.

It can cause morbidity and mortality on its own and complicates many medical conditions. Dehydration may also be over-diagnosed.

This can lead to misdiagnosis of the real cause of the patient's illness and lead to over-treatment with fluids. Dehydration is easily treatable and preventable. A thorough understanding of the causes and diagnosis of dehydration can improve patient care. Body water is lost through the skin, lungs, kidneys, and GI tract.

The loss of body water without sodium causes dehydration. Water is lost from the skin, lungs, gastrointestinal tract, and kidneys. Dehydration results when water losses from the body exceed water replacement. It may be caused by failure to replace obligate water losses. There are several forms of dehydration.

Causes of isotonic water loss are vomiting, diarrhea, sweating, burns, intrinsic kidney disease, hyperglycemia, and hypoaldosteronism. Hypertonic dehydration occurs when water losses exceed sodium losses. Serum sodium and osmolality will always be elevated in hypertonic dehydration.

Excess pure water loss occurs through the skin, lungs, and kidneys. Etiologies are fever, increased respiration, and diabetes insipidus. Hypotonic dehydration is mostly caused by diuretics, which cause more sodium loss than water loss. Hypotonic dehydration is characterized by low sodium and osmolality.

There is no recent data on rates of dehydration in the general population, but we do know much of the epidemiology of dehydration in adults. Healthy adults with access to water rarely become dehydrated.

Any adult may develop dehydration as a complication of an illness such as hyperglycemia. Dehydration may cause illness or be caused by an illness, so searches of databases may not capture all cases of dehydration.

The data that we do have shows that older adults are more likely to develop dehydration. Water plays a key role in maintaining multiple physiological functions within the body. Two-thirds of that water is intracellular, and one-third is extracellular. One-fifth of extracellular water is intravascular.

The body has a complex system designed to maintain euvolemia. Water is absorbed through the gastrointestinal tract. The primary control of water homeostasis is through osmoreceptors in the brain.

As perceived by these osmoreceptors, dehydration stimulates the thirst center in the hypothalamus, which leads to water consumption. These osmoreceptors can also cause the conservation of water by the kidney. When the hypothalamus detects lower water concentration, it causes the posterior pituitary to release antidiuretic hormone ADH , which stimulates the kidneys to reabsorb more water.

Decreased blood pressure, which often accompanies dehydration, triggers renin secretion from the kidney. Renin converts angiotensin I to angiotensin II, which increases aldosterone release from the adrenals. Aldosterone increases the absorption of sodium and water from the kidney.

Using these mechanisms, the body regulates body volume and sodium and water concentration. Hypovolemic patients can present with a wide assortment of symptoms and physical exam findings. Some of the most common presenting symptoms of dehydration include but are not limited to fatigue, thirst, dry skin and lips, dark urine or decreased urine output, headaches, muscle cramps, lightheadedness, dizziness, syncope, orthostatic hypotension, and palpitations.

The patient's history may elicit factors that could cause dehydration, such as exercise, heat exposure, medications, illness, impaired access to water, fever, or fluid loss. Vital signs may show hypotension, tachycardia, fever, and tachypnea. Hypotension will not appear until significant dehydration is present.

Tachycardia may be absent due to medications such as beta-blockers. A patient may appear lethargic or obtunded upon observation in severe cases of dehydration.

The physical examination could show dry mucosa, skin tenting, delayed capillary refill, or cracked lips. A Cochrane review evaluated predictors of dehydration in the elderly.

Of all these factors, only fatigue and missed drinks between meals predicted the diagnosis of dehydration. There is no gold standard test for dehydration. Serum and plasma osmolality tests are often used to diagnose but may be affected by fluid loss or fluid loss acuity. The Cochrane review of diagnostic tests for dehydration in elderly patients, bioelectrical impedance analysis, urine specific gravity, the osmolality of urine, saliva, or tears, tear volume, number of urine voids, and urine volume were not useful as stand-alone tests for dehydration in the elderly.

Blood urea nitrogen to creatinine ratio should be higher than in dehydration, but this may be mimicked by high urea production, low creatinine due to low muscle lass, and urea reabsorption due to upper gastrointestinal bleed. Urine tests may suggest volume depletion. These tests of renal perception of low blood flow may also be abnormal in heart failure, cirrhosis, nephrotic syndrome, and other causes of kidney disease.

IVC collapse with inspiration may correlate with right atrial pressure and intravascular volume. IVC ultrasound has limited ability to predict fluid responsiveness. Treatment of dehydration is aimed at rapid fluid replacement as well as identification of the cause of fluid loss.

Patients with fluid deficits should be given isotonic fluid boluses tailored to the individual circumstance. Patients with more severe dehydration get larger boluses of isotonic fluid. A more careful approach is needed in elderly patients and patients with heart failure and kidney failure.

In these patients, small boluses should be given, followed by frequent reassessment and additional bolus as needed. Blood pressure, heart rate, serum lactate, hematocrit if bleeding, there is no blood loss , and urine output may be used to assess the volume deficit and to assess response to fluids.

Isotonic crystalloid fluid should be used in most cases of dehydration. Colloids such as albumin may be used in specific situations but do not improve outcomes. The choice of crystalloid should be customized to the patient.

Normal saline lactated Ringer's solution and a balanced crystalloid solution may all be used. Normal saline may cause hyperchloremic metabolic acidosis in large volumes. Buffered crystalloids may cause hyponatremia.

Lactated Ringer's solution also contains potassium, so it should not be used in renal failure or hyperkalemia. No fluid has proved superior in all patients. In patients with dehydration and severe hyponatremia, rapid volume repletion may cause a rapid rise in sodium.

This can cause central pontine myelinolysis CPM. The clinician must weigh the risks of continued dehydration against the risks of CPM. The patient's volume status and serum sodium must be followed closely. As the patient is being resuscitated, clinical and laboratory examination must focus on the discovery and correction of the cause of dehydration.

The principle differential of dehydration in adults is the loss of body water versus the loss of blood. This is important because blood loss should be replaced with blood, while water loss should be replaced with fluid.

The next point to consider is the differential diagnosis of the cause of dehydration, as discussed under etiology. When the underlying cause of dehydration is treated, and the patient's volume has been restored, the majority of patients recover fully.

Failure to treat dehydration in older adults may lead to significant mortality. Complications of dehydration occur due to inadequate fluid replacement and over-aggressive fluid replacement.

Complications of under-resuscitation are due to hypoperfusion of vital organs and complications due to renal efforts to retain fluid. Altered mental status, renal failure, shock liver, lactic acidosis, hypotension, and death are related to organ-hypoperfusion.

Fluid and electrolyte abnormalities such as uremia, hyponatremia, hypernatremia, hypokalemia, hyperkalemia, metabolic acidosis, and metabolic alkalosis may occur.

Excess fluid administration to correct dehydration may cause peripheral edema and pulmonary edema. In patients with severe hyponatremia, volume correction may cause a rapid rise in sodium, which can cause central pontine myelinolysis.

Renal consultation will be needed at times, especially with severe hyponatremia, but in most cases, the treating clinician can evaluate and correct dehydration. Although the CDC does not have defined water intake recommendations, adults are encouraged to maintain between L per day.

For example, marathon runners water should drink more than a nonmobile person. In elderly patients, excessive free water drinking can cause hyponatremia, so balanced hydration solutions are recommended.
