Vomiting

so I have a question for all. I am 2 years post op still sitting at my lowest weight thank the lord, but this past week it seems every time I eat I get sick on my stomach. I'm not over eating at all honestly I am under eating because I start to feel sick. Anyone have anything similar happen? To me it's so strange since I am 2 years out and have never had a problem. Please help anyone 

Stomach flu or a stricture maybe.  

May not be Wls related.

I have just gone thru gastritis and a marginal ulcer. even water made me feel sick. Id make an appointment with you Doctor for a EDG if it last more than 5 days

If you'll put your surgery type and date on your profile, it will show up each time you post. This is info that helps us help you.

For now---which form of WLS did you have? Is it ONLY when you eat that you feel sick? What happens when you drink? (Any chance you're dehydrated? Being dehydrated makes you sick at your stomach sometimes.) Are you pooping daily? Constipation can also make you queasy.
