Hello, Thanks for writing in. I am sorry your elderly father had to undergo such discomfort which is continuing. Apparently, some terrible mistake might have has occurred during GB surgery like injury
to bile duct. Please take the opinion of a Gastroenterology Specialist. The symptoms you have described does not fit in post bypass surgery
problems (undoubtedly with blocked arteries that was indicated). Second choice would be a senior Internal Medicine Specialist for fresh look. You can upload investigations and write a detailed history chronologically mentioning the dates, of illness and treatment so that we can get the hang of exact problem. Frankly, this history has knocked me out of my wits. May your father have course to recovery now.
With Best Wishes.
