Fluid imbalance

The main components of body fluids are water and electrolytes. It is divided into two parts, cell and extracellular fluid, the amount of which varies with sex, age, and leanness. The body fluid volume of adult men is generally 60% of body weight; the body fluid volume of adult women accounts for about 55% of body weight. Children have less fat, so body fluids account for a higher proportion of body weight, which can reach 80% of body weight in newborns. The amount of body fat increases with age. After 14 years of age, the proportion of children's body fluids in body weight is similar to that of adults. Imbalance of fluid balance can cause disturbances in the balance of the body.
