I had gastric bypass surgery on march 5. I'm using isopure protein which is clear wheyprotein. I have had watery diarrhea since 2nd day after surgery. Common after rny surgery or protein related?

Post surgery care: Diarrhea after bowel surgery can have several causes, from normal to infection related. The dietary protein might be a contributor. However, it is a good idea to discuss this with your surgeon, as we want to rule out the more serious causes right away. A stool sample to check for infection/c. Diff is easy and will help you. Early diagnosis and treatment is the goal during recovery. ...Read more

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's, (5'4", 203), but isn't there a less invasive answer?

Options: Probably theist popular weight loss operation at the moment is a sleeve gastrectomy. Its not really less invasive, but has less potential for long term side effects. There are also some newer endoscopic therapies, but they are not so effective. Ask your doctor if a consultation with a Bariatric surgeon is appropriate. Hope this helps! ...Read more

Is the mini gastric bypass safe or better than the?

Mini gastric bypass: The mini gastric bypass is not endorsed by any asmbs or any of the top academic bariatric surgery programs in the country. It is safe, but it is basically a billroth 2 operation which can cause bile reflux.
