Reduction in Weight and Increased Flatulence
A common manifestation of ulcerative colitis is loss of weight. Weight loss is a symptom of malnutrition caused by the fact that you do not get enough calories to satisfy the demands of your body. There are many explanations for this phenomenon, such as poor appetite.
If ulcerative colitis causes you to lose weight, try eating five or six small meals during the day rather than two or three big meals per day.
Poor appetite is also associated with nausea and the desire to vomit. This will prevent you from proper nutrition and leave your body lacking in necessary needs. At the same time, nutrient absorption in the intestines can be impaired such as iron which leads to iron deficiency in the body.
Often, colitis will lead you to feel bloated and gassy. Firstly, patients with ulcerative colitis tend to produce more hydrogen sulfide [6] than average and have a harder time breaking down the gas (probably because they already have an inflammation of the lining of their abdominal wall). The additional gas present will damage the colon’s lining further.
