About Constipation: Making the Diagnosis
If constipation is a problem, see your doctor. A physical exam will show whether there are hard stools in your intestine or any unusual masses in your stomach. This will include a digital rectal exam to check muscle tone.
Your doctor might do a sigmoidoscopy or colonoscopy. This involves using a lighted tube with a camera on the end to look into part or all of the large intestine. A barium enema allows abnormalities of the large intestine to be seen on an x-ray.
