TCM Treatment Based on Syndrome Differentiation:
In the treatment of diarrhea, first determine whether it is acute or chronic. The treatment of acute diarrhea is based on the elimination of Dampness. Additional treatment will depend on which additional exogeneous evil has joined with Dampness. The treatment of chronic diarrhea is based on strengthening the spleen, complemented by additional treatment as needed. For acute diarrhea, do not apply vigorous restoration or astringency, so as not to trap the exogenous evil within. For chronic diarrhea, be cautious in treatment during defervescence of fever through sweating in order to avoid aggravating depletion of Yin-fluids.

Treatment in Western Medicine:
In most cases, replacing lost fluid to prevent dehydration is the only treatment necessary. Medicines that stop diarrhea may be helpful in some cases, but they are not recommended for people whose diarrhea is caused by a bacterial infection or parasite - stopping the diarrhea traps the organism in the intestines, prolonging the problem. Instead, doctors may prescribe antibiotics. Viral causes may be treated with medication or left to run their course, depending on the severity and type of the virus.

Diarrhea and Food
Until diarrhea subsides, try to avoid milk products and foods that are greasy, high-fiber, or very sweet. These foods tend to aggravate diarrhea.
As you improve, you can add soft, bland foods to your diet, including bananas, plain rice, boiled potatoes, toast, crackers, cooked carrots, and baked chicken without the skin or fat. For children, the pediatrician may recommend what is called the BRAT diet: bananas, rice, applesauce, and toast.
