Dehydration is caused by a lack of water, which occurs when your body does not have enough to meet its requirements. It happens when your body loses more fluids than it takes in. If the situation is not addressed, it has the potential to deteriorate and become a significant issue. Your body cannot operate correctly if you do not consume enough calories. Dehydration is classified as mild, moderate, or severe based on the amount of fluid lost and the severity of the dehydration.

Dehydration (ICD: E86.0) may affect everyone, but it is especially hazardous for babies and the elderly.

Severe diarrhea and vomiting are the most frequent causes of dehydration in children under the age of five. Adults over the age of 65 often have a limited quantity of water, and they may be ill or on medicines that enhance their risk of dehydration.

Dehydration is a concern for older people who have mild diseases, such as lungs or bladder infections, which may cause dehydration.

In hot weather, anybody, regardless of age, may get dehydration symptoms if they do not drink enough water. This is particularly true if they are engaging in intense physical exercise.

Adding additional fluids may help reverse mild to moderate dehydration in most instances; however, severe dehydration should be treated immediately by a medical professional.

Signs of dehydration in adults are:

·         Sticky or dry mouth

·         Sunken eyes

·         Dry or dehydrated skin

·         Drowsiness

As a result of dehydration reaction and electrolyte depletion, your body attempts to save as much fluid as possible. Therefore, less saliva is produced, allowing germs to flourish and increasing the chance of having white tongue.

Severe dehydration can cause diarrhea, nausea and fever.

Muscle cramps, headache, thirst and dark yellow urine are symptoms of dehydration in women.

Dehydration therapy is an attempt to replenish your body’s fluids and electrolytes that have been depleted. If your sickness is minor, all you need to do is drink enough water to get rid of it. If you have depleted your electrolytes after an exercise, sports drinks may assist. Oral rehydration therapies for children are now available on the market. These are non-prescription medications that may be bought without a prescription.

In the most severe cases, acute intravenous (IV) fluids containing salt may be administered in a hospital setting.


Dehydration is most often caused by a lack of fluids to replenish what we have lost via perspiration or exercise. Dehydration may be caused by a variety of factors, including the temperature, the amount of physical activity you engage in (especially during the summer), and your nutrition.

Dehydration may also be induced by medical conditions such as persistent vomiting and diarrhea, or excessive perspiration because of an illness or fever.

Diabetes that is uncontrolled or mistreated makes you more prone to dehydration, which may be deadly. If you have renal illness or take medicines that induce frequent urine, your risk is enhanced. Even if you have a cold or a sore throat, you are more prone to dehydration since you are less inclined to eat or drink while sick or feeling ill.

Exercising outside further increases the risk of dehydration. When the weather is hot and humid, the risk of dehydration and heat exhaustion increases. When perspiration is unable to escape fast enough to cool you down in a humid environment, your core body temperature rises and you need more fluids.

You may be unable to replace the water you lose for the following reasons:

·         You may forget to drink enough water due to your busy routine.

·         You do not feel thirst.

·         You do not want to drink because your throat or mouth sores bother you, or because you are feeling nauseous.

Excessive intake of caffeinated beverages like coffee may cause dehydration. However, coffee in normal quantities does not seem to raise the risk of dehydration.

When to see a doctor

If you exhibit any of the symptoms mentioned below, see your health care physician.

·         Vomiting or diarrhea for 24 hours

·         Extreme thirst

·         Feeling angry or confused

·         Laziness

·         Trouble maintaining consistent water levels.

·         Stool with red or dark hue

Consult your doctor if your symptoms persist despite your efforts to drink lots of water, or if you suspect your infant or toddler is dehydrated.

If your doctor thinks you are dehydrated, he or she may order a blood or urine test to confirm the diagnosis. These tests will establish the salt balance in your body.
