What's wrong with eating less and pulling more?

There are many reasons for the patient to show less diarrhea, among which the following are more common: 1. It may be because the patient's gastrointestinal digestion and absorption function is not good, resulting in food eaten into the stomach can not be completely absorbed by the patient's stomach, thus leading to the situation of eating less diarrhea and more diarrhea. 2. It may be caused by the patient suffering from congenital megacolon disease, which normally also shows diarrhea, vomiting and other manifestations. It is recommended that the patient be treated in time.
