I see that you have had several surgeries, and the last one was earlier this year. As you know, it does take the digestive tract some time to heal and adjust to this new normal. One thing that might be very helpful to you would be to consult with a registered hospital dietitian. If you have not met with one of these professionals yet, I would highly encourage you to ask your doctor for a referral.

I've personally had three resection surgeries of the upper digestive tract and have found the suggestions and help of registered dietician to be valuable. Have you had this type of appointment?
