I had gbp 11/21, lost 60lbs. Food goes down fine but when it hits the pouch it hurts. Having trouble getting protein. Shakes cause vomitting/diarrhea.?

Call doc. Need to speak with surgeon, get examined. Can have problems with narrowing, scarring, (or not). Narrowings can often be stretched through an endoscope. Watch out for "dumping syndrome"-diarrhea after eating simple sugars. Call doc.
