Dehydration: Causes, Signs, Symptoms, Treatment, Prevention


Dehydration is a common problem faced by many people, particularly during excessive heat, sports or after illnesses. As the water in your body contains salts and electrolytes, when water is lost, the salts are lost. This creates an electrolyte imbalance, leading to various health problems. Dehydration can thus result in undesirable symptoms. It is important to know the causes, symptoms, treatment and the ways of prevention of dehydration in the body.


Causes of Dehydration:

Some of the common causes of dehydration include the following conditions.

  • Excessive heating and over exertion are the common causes of dehydration. When you have a fever or are exposed to heat for long or have done heavy exercises, you are at risk of water loss and dehydration.
  • Diabetes is another common cause of dehydration. Diabetes Miletus (type 2) is often treated with an enzyme called insulin, which needs adequate amount of water. Also, as diabetics lose a lot of water with increased urination, there is more water loss, which are the common causes of dehydration.
  • An upset stomach, food poisoning, etc. often causes water loss in the form of vomiting and diarrhea. They force all the water in your body out and hence there is shortage of water and electrolytes in the body. Water loss in such forms too are the common causes of dehydration.
  • If you don’t take food and water for quite a long time in a day your body has nothing to do digest. So it uses the available water and minerals and provides energy to the body. So when all the water is used up the body runs low on water.
  • Significant amount of water can be lost from damaged skin. Sores, wounds, scalds, skin diseases and infections can be some of the causes of dehydration.
  • Consumption of alcohol and various drugs, blood pressure medications and antipsychotics that cause increased urination can also cause dehydration.

People who exercise, play sports or go out for cycling, jogging, etc. need to be more careful. Wear light cotton clothes that allow you to cool and avoid getting overheated. Sip on water at regular intervals, fresh fruit juices or drinks with salts and electrolytes, carry fruits like melons, berries and citrus fruits and they are rich in water content. Ensure you consume proper balanced nutritious meals even if you are trying to lose weight. Carry healthy low fat snacks, dry fruits, when going out.
