I am a liver/kidney recipient. My gall bladder was removed at time of my transplant. I was prescribed omeprazole after my transplant to counteract heartburn which many patients have experienced.
I was advised to:
Avoid fatty, greasy, or spicy foods.
Eat lean meat, low-fat dairy, and leafy green vegetables.
Eat low-fat diet rich in fruits, vegetables, lean proteins, and whole grains.
Eat smaller, more frequent meals.

-Heartburn after liver transplant: How do I get relief?

To this day. 16 years post transplant, I have a difficult time after eating spicy or fried foods - except occasional small portions.
Are you a liver transplant recipient? Does your transplant team think that a medication switch is what you need?
