Why do people with colitis keep losing weight?

People with colitis tend to become increasingly thin, usually due to decreased appetite and nutrient loss. The clinical symptoms of the aforementioned condition include increased frequency of bowel movements, abdominal pain, and bloating. Patients experience more frequent bowel movements, leading to significant loss of water, nutrients, and electrolytes. Over time, this can result in malnutrition and weight loss. Patients may use medications such as Changyanning tablets or Shenling Baizhu powder to treat the condition and regulate gastrointestinal function.
