Constipation is defined as having less than three bowel movements per week or hard stools that are difficult to pass. Common causes include low-fiber diets, lack of physical activity, certain medications, and ignoring the urge to have a bowel movement. Diagnosis involves physical exams, blood tests, and imaging tests of the colon and rectum. Treatment begins with lifestyle changes like increasing fiber intake and exercise. If those don't help, doctors may prescribe laxatives, stool softeners, or suppositories to relieve constipation symptoms.
