Gastrointestinal disorders include such conditions as constipation, irritable bowel syndrome, hemorrhoids, anal fissures, perianal abscesses, anal fistulas, perianal infections, diverticular diseases, colitis, colon polyps, and cancer. Many of these can be prevented or minimized by maintaining a healthy lifestyle, practicing good bowel habits, and submitting to cancer
screening. Constipation means it's hard to have a bowel movement (or pass stools), they are infrequent (less than three times a week) or incomplete. Constipation is usually caused by inadequate "roughage" or fiber in the diet, or a disruption of the regular routine or diet. Constipation causes a person to strain during a bowel movement. It may cause small, hard stools and sometimes anal problems such as fissures and hemorrhoids. Constipation is rarely the sign of a more serious medical condition. Structural disorders are those in which the bowel looks abnormal and doesn't work properly. Sometimes, the structural abnormality needs to be removed surgically. Common examples of structural GI disorders include hemorrhoids, diverticular disease, colon polyps, colon cancer, and inflammatory bowel disease.
