If there are symptoms of body wasting due to colitis, treatment should first be directed at the colitis to control the condition.

After controlling the condition, it is possible to reduce symptoms of diarrhea and abdominal pain, which is conducive to the digestion and absorption of nutrients in food and can help enhance physical fitness. Normally, care should be taken not to overeat or drink excessively. It is okay to eat moderate amounts of eggs, meat, and dairy, but be careful not to eat too much at once, as this can aggravate the symptoms of colitis.
