Dehydration – Causes, Signs, Symptoms & Prevention

Human body comprises 75% water which is present in both intracellularly and extracellularly. Dehydration refers to a condition that involves excessive loss of body water, leading to disturbed metabolic processes. It is generally an imbalance between water loss vs. water intake. CAUSES Diarrhea – Usually when large intestine is unable to hold water in a condition like fever or infections, it excretes water resulting in dehydration. Vomiting – Nausea & vomiting restricts the ability to hold down water thereby reducing the intake. Sweating – In certain conditions like humid and hot weather, strenuous physical activity and fever, the sweating increases. This is body’s defense mechanism which leads to dehydration. Diabetes – Due to the consistent rise in blood sugar, the body tends to excrete glucose via urine, removing water along with it and leads to dehydration. Frequent urination – Conditions like diabetes, excessive alcohol intake, and certain medications such as diuretics, antihypertensives, antihistamines, antipsychotics, leads to frequent urination. Burns – Skin is the first protective barrier for the body which also regulates fluid loss. Dehydration in burn cases is caused due to the inability of the skin to prevent this fluid loss.
