What Causes Dehydration in Body?

Why do we get Dehydrated?

Dehydration occurs when our body loses more fluids than we drink. 75% of our body weight is water. Water regulates our body temperature, digestion. It acts a lubricant and cushions our joints, etc. Now, we lose water through breathing, sweating, peeing, etc. As little as 2% loss of our body fluids makes us thirsty. And when we lose 4 to 5% of our body fluids, we begin to feel dehydrated. Common causes of dehydration include diarrhoea, vomiting and excessive sweating. Some conditions like diabetes and diuretic medications. Which cause us to urinate frequently can also leave us dehydrated. Now, mild dehydration can cause irritation, headache, dizziness, etc. However, long-term dehydration or chronic dehydration. Can lead to decrease in blood volume. Thus reducing the amount of oxygen reaching our tissues. Chronic dehydration can even cause. Urinary tract infection, kidney failure and in severe cases, death.
