Colitis should be diarrhea! Is "black and dry" hope or dry? The stool is dark, abdominal pain may have slight bleeding, and the stomach should not be very good. You can use soybean milk instead of milk. Although milk is good, not many people can absorb it well, especially Asians. It is not easy to exercise excessively. It is difficult to cure the gastrointestinal tract, and your thinking is still right. It's a three-point poison. I don't know how long you've been in this situation. Treating gastrointestinal roots means strengthening the spleen, so don't stay up late.
