4Loss of Appetite
With ulcerative colitis, your immune system will activate constantly to heal ulcers. In addition, abdominal pain and chronic diarrhea would trigger nausea. The combination of these conditions often makes you lose your appetite and eat less than usual. As a result, you might drop unexpected weights in a short time. Some people with this disease also tend to avoid eating to minimize inflammation in the digestive system. If left untreated for an extended period, it might lead to nutritional deficiencies and worsen your conditions. [4]
