Diarrhea does not lead to wasting, often referred to as diarrhea diarrhea, most are (intestinal) capillary permeability caused by the increase in the number of diarrhea, resulting in increased water loss in the body, and the increase in water loss can not directly cause the body to lose weight, but only the effective circulation of blood in the body decreased. The clinical term “wasting” mainly refers to fat metabolism, protein consumption and amino acid consumption. So for the wasting, the most important thing is still the consumption of fat, diarrhea diarrhea will not lead to fat wasting, only may in repeated stimulation, causing hunger will lead to the consumption of fat. Therefore, diarrhea alone will not lead to wasting, but will only lead to a decrease in effective circulating blood volume and cause dehydration, dehydration will not lead to wasting.
