Trouble eating and drinking
I had a similar problem within a few weeks after my surgery (11 years ago today). Luckily I fell into the hands of a great gastroenterologist who said the stoma needed to be stretched just a little bit. That immediately fixed the problem, but it came back about 8 months later. The same doctor did the same (small out-patient) procedure again - and I've never had trouble again! I hope your problem is that simple. If you don't get a satisfactory answer from your Bariatric surgeon ask to see the Gastroenterologist that he refers his patients to when complications occur. Best of luck to you.
