@tennisgolf, My gall bladder was removed when I had a liver transplant, and my husband's was removed several years ago. My husband was advised to limit the amount of fat in his diet. My surgery was 11 years ago and I don't remember what I was told specifically about a gall bladder diet, but I do try to avoid fatty foods and fried foods as recommended as part of my post transplant healthy eating focus.

I found this short article from Mayo that does mention fat and fiber could cause gas and bloating.

Have you asked your doctor what could be the cause? Could it be related to what you eat?

Hello @tennisgolf

Many members on Connect have posted about digestive issues post-gall bladder surgery. Here is one of those discussion groups that you might find interesting and/or helpful.

While many feel that after gall bladder removal they can eat whatever they want, most often that is not the case. It might be helpful to keep a food diary and see if there are any foods in particular that trigger the symptoms you are having.

I'm just wondering, was your gall bladder surgery an open surgery or was it done laparoscopically?
