6+ Causes of Dehydration You Must Know

What are the causes of dehydration?

Dehydration can happen to anyone and at any time. Not only does it make you thirsty, dehydration can interfere with body functions and cause loss of consciousness. For this reason, meeting the body's fluid needs, drinking at least 8 glasses a day is very important to maintain body hydration. Most people attribute lack of drinking to a cause of dehydration. Though there are several causes that you need to be aware of in order to prevent it. Some of the most common causes of dehydration that you need to be aware of include:

1. Fever

Fever is the most common cause of dehydration and sometimes goes unnotified. During a fever, the body loses fluids through the skin's surface in an effort to lower body temperature. Hence, you may sweat more when you have a fever. No wonder you are advised to drink more and meet fluid needs when you have a fever. This is to prevent further dehydration.

2. Vomit

vomiting Constant The reason, vomiting makes a lot of body fluids out. In addition to losing body fluids, vomiting can also disrupt the electrolyte balance that the body needs to control organs, muscles, and body chemistry. If allowed to drag on, the dangers of dehydration and electrolyte imbalance can become severe, even leading to serious problems such as seizures, coma, and cardiac arrest.

3. Diarrhea

Similar to vomiting, diarrhea also causes more body fluids to come out through liquid stools and frequent bowel movements. Not only fluids, electrolytes in the body can also be lost in a short time when diarrhea occurs. This can interfere with body functions to cause fatal complications.

4. Gastroenteritis

Gastroenteritis can also be a cause of dehydration. Gastroenteritis, also known as stomach flu, is an inflammation of the lining of the digestive tract that causes vomiting. Vomiting is a condition of vomiting and diarrhea that occur together. Lack of fluids in the body caused by gastroenteritis can be very extreme due to the loss of a lot of body fluids through vomiting and diarrhea.

5. Diabetes

Diabetes can cause you to lose more body fluids. This makes the kidneys work harder to get rid of glucose by making more urine. As a result, you become more frequent urination . This is what causes dehydration in people with diabetes.

6. Kidney disease

People with chronic diseases such as kidney disease are more at risk of becoming dehydrated. The kidneys have an important role in maintaining fluid balance. The presence of problems with the kidneys also contributes to disturbances in the body's fluid and electrolyte balance which can lead to dehydration.

7. Medicines

Certain medications can also be a contributing factor to dehydration. Some types of drugs that cause the body to lose more fluids, including:

  •     Laxatives or laxatives
  •     Type 2 diabetes medication
  •     Certain analgesic drugs
  •     Hypertension medicine
  •     Diuretic drugs for heart failure
  •     Psoriasis medications, such as apremilast
  •     Chemotherapy drugs
  •     Bipolar disorder medications containing lithium

8. Excessive sweating

Sweating is the body's natural cooling process. In addition to maintaining body temperature and hydrating the skin, sweating also maintains the electrolyte balance in the body. However, the condition of hyperhidrosis or excessive sweating can cause dehydration because the body loses a lot of fluids.

9. Ambient temperature

Hot and humid weather can increase the risk of dehydration. High ambient temperature will cause an increase in body temperature. 

First aid for dehydration

The main aid when signs of dehydration is to replace lost body fluids and electrolytes. Quoted from the Mayo Clinic , how to deal with dehydration needs to be adjusted to the cause of dehydration, severity, and age.

  1. For infants and children, dehydration that occurs due to fever, vomiting, or diarrhea can be overcome by drinking ORS or those containing water and salt.
  2. For adults, drinking more water or fluid intake can help with mild to moderate dehydration
  3. In more severe conditions, both children and adults require more intensive care with intravenous fluids and electrolytes

If you or your child has severe diarrhea or vomiting, don't forget to pay attention to their general condition. Weakness is a sign that someone needs to get immediate medical attention to the hospital.
