10 year post distal gastric bypass (open) patient. Developed fissure and finally an anal fistula. Treatment? Additionally!!!! Vit D deficiency ............taking 50,000 mg 2x's a week.............still no help. What is treatment for vit d and malabsorption? Developed osteoporosis. I am a 51 year old female. Help, my Physician is not sure what course of action to take with me........I am sure other patients have had this type of surgery (distal). Causing 5 to 7 bowel movements a day...................nothing absorbs. Any insight or physician referral is truly appreciated
