Description Of Dehydration
Two thirds of the body are composed of water. This means that if a person weighs about 70 kilos (154 pounds), the human body contains about 45 liters of water. Nearly 70% of water is contained in cells, 20% in the space surrounding cells and less than 10% in the bloodstream. Water is essential to maintaining a healthy body.
When water intake is the amount excreted, water reserves of the body are well balanced. A healthy person, do not sweat excessively, you should drink at least two to three liters of fluid per day to maintain water balance and protect against the development of kidney stones.
Dehydration can occur when the water body is insufficient. If the brain and kidneys are functioning properly, the body can adapt to changes in water intake. It is usually possible to drink enough water to offset losses.
In certain circumstances it is impossible to drink enough water because of vomiting, acute diarrhea, excessive heat or fever.
Some dehydration is relatively mild, but can pose a mortal danger. When the water reserves in the body lowered below a certain threshold, a condition that means hypovolemic shock can occur when blood volume decreases rapidly.
Dehydration is a serious problem in young children and infants due to the greater proportion of their skin surface area relative to their body as a whole, and can occur even after several hours of vomiting or diarrhea and even d ‘profuse sweating.
