Difficulty in bowel movement refers to impaired defecation, accompanied by recent changes in bowel habits and stool characteristics. Other symptoms such as weight loss and fatigue may also occur. First, it is important to rule out malignant conditions—for example, any mass inside the intestine causing obstruction and preventing normal excretion. Colonic inflammation can lead to constipation, such as in ulcerative colitis. If the rectum is involved, a sensation of incomplete evacuation may develop, and the stool may contain mucus, pus, or blood.
