What is the problem with infrequent bowel movements? Infrequent bowel movements are first considered to be constipation. Constipation refers to a decrease in the number of bowel movements, usually less than three times a week, accompanied by difficulty in defecation and dry stools. If you have infrequent bowel movements, we should first consider that if we exclude functional constipation, we can determine that it is caused by organic diseases. Constipation is commonly caused by lesions of the rectum and anus, such as hemorrhoids, anal fissures, and ulcers. It can also be a localized lesion causing weakness of defecation, such as massive ascites. Complete or incomplete obstruction of the colon can also cause constipation, such as tumors, Crohn’s disease, various causes of intestinal torsion, intussusception, etc., as well as some tumors of the abdominal and pelvic cavities, etc.
