How to understand and prevent dehydration

Dehydration and heat stroke 

Dehydration means losing to much water, the human body contains approximately 76% of the water.

Water is bound up with the cell, within the blood and in between the cell (cytoplasm) 
Without water we can not survive, water is continuously evaporated when we breathe, sweat and excrete by when we urinated and defecate.

In dehydration process, electrolytic imbalance. 
the imbalance may occur since important chemicals (like sodium, potassium, and chloride) are lost from the body through sweat. For example, patients with suffering from diarrhea or vomiting may lose excess amounts of potassium, causing muscle weakness and heart rhythm disturbances.  

Causes of dehydration 

  •  Diarrhea 
  •  Vomiting 
  •  Sweating 

Dehydration symptoms 

 1- Headache 
 2- Dry mouth 
 3- Lethargy 
 4- Dizziness 
 5- Sedation
 6- Urine concentrated and color maybe darker 

 How to understand and prevent dehydration


Diarrhea – The main reason for fluid loss with sudden vigorous dehydration and related deaths. The large intestine can’t absorb water from food matter,  The body excretes too much water, leading to dehydration.

Vomiting – Excessive loss of fluids and electrolytes from the body makes it difficult to replace water by drinking it.

Frequent urination- Generally caused due to uncontrolled levels of diabetes, other reasons like the use of some drugs,
alcohols and medications such as diuretics, antihistamines, blood pressure medications, and antipsychotics.
Excessive Sweating – The body’s cooling mechanism releases a significant amount of water. But Hot and humid weather conditions and vigorous physical activities like athletes and more exercises can further increase fluid loss from the body in form of sweating.

Diabetes – high blood sugar levels cause increased urination and fluid loss.

Prevention from dehydration

Prevention is the most important treatment for dehydration. Consuming a lot’s of fluids and foods that have high water content (like fruits and green vegetables) it’s enough for most people to prevent dehydration.

People should be avoided to hard work in hot summer day about doing extreme heat of the day, and anyone who is exercising should take fluid in regular intervals to avoid excess loss of electrolytes in the form of sweating.

Elderly and children’s are most at risk of being dehydrated, so special attention should be given to them to make sure they are receiving enough fluids with electrolytes.
