Rectal prolapse is suggested by your description, constipation is to be avoided at all cost, pelvic floor exercises may help.

For best evaluation and advice, consult a proctologist or colorectal surgeon who has a special interest in rectal prolapse treatment. You may have to see one at a department of proctology at a university hospital or academic center near you.

Agree with Dr. P. To avoid constipation You may take a fiber laxative like Metamucil and drink enough water daily so that your urine is colorless. For the long term you may try to increase your intake of fiber foods. Consult this site for fiber foods. http://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/high-fiber-foods/art-20050948 Wish you good health!
