What is the most important factor for the diet of someone who had a gallbladder stones removal surgery?

As a retired RN I would reassure you that speaking with your OWN doctor is crucial. The advice and counsel of lay people on some Forum, their own experiences is likely only to add confusion. Your doctor knows the patient, sees the patient, has access to the patient for exam and for any blood test results, scans, history and etc.

There are some questions that belong in the realm of the experts. Legal needs the attorney. Medical needs the doctor.

I sure wish all the best going forward.

Generally, they say to keep the diet low fat for a while and the gradually introduce fats in and see how his body reacts. Some people have urgency to toilet after eating fats after gallbladder surgery and some don’t.

Have you spoke with a Dietitian or Nutritionist?

Usually the bladder is also taken when there are gallstones.

Since Gallstones are the problem, there is really no special diet. But some people can't eat after the surgery what they couldn't eat before. Me, I seem to suffer from not producing enough bile. So small meals are recommended. I am finding that greasy foods effect me. So no more sausage, scrapple or bacon or fried foods. Chocolate effects some people.

I think you just need to experiment. Both my parents had their gallbladders removed when they had gallstones. Neither had a special diet. If there were foods that bothered Uncle before, introduce them back into his diet and see if it effects him. If so, you know he can't eat that.

If he is having problems in other areas, a diet plan maybe needed for them. So, I agree, that you need to talk to his doctor about his diet.

I would call his dr and press the nurse for more guidance..
