Still vomiting every day several times after Roux en Y Gastric Pass. What can stop it?

Anna,
You probably have a "stricture" or narrowing at the connection between your new stomach pouch and the intestines.  It is a known complication after gastric bypass and must be ruled out if a patient can not tolerate solids in the first few months after surgery.  Contact your surgeons office and they should arrange for a GI doctor to stretch the openning for you.  It is a pretty simple outpatient procedure.  In the meantime, push your fluids and protein drinks so you don't get dehydrated or malnourished. If you can not tolerate fluids then you should go to your local emergency room for evaluation.   
Take care,
Dr H

It isn't rare to get a stricture at the gastrojejunostomy, the opening between your stomach pouch and the attachment to the small intestine.  Perhaps it's time to have an endoscopy and possibly a balloon dilation of the stricture.
