Im drinking ensure plus to increase my weigh after having a massive obstruction removed from my large intestine which has left me with a colostomy. I constantly get severe abdominal pain when I have ensure first thing in the morning. Ive tried having a  cup of black tea & I dont have anything else that contains milk. Please help as I need to increase my weight prior to having my reversal done in may.
First you need to do further tests to rule out some possible obstructions. Also, some allergy reactions to food may cause similar difficulties. Wish you good health. Regards
