What are types of eating disorders?

There are 3 different types of eating disorders. One of these is Anorexia nervosa, this is when a person doesn't eat enough to maintain a healthy body weight.

A second type is Bulimia, this is when a person has uncontrolled eating binges followed by a purge (throwing up the food)

A third type is Binge eating disorder which is the uncontrollable urge to eat large amounts of food.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
