I was wondering how many people experience headaches after eating. It does not seem to matter what I eat and does not seem to be linked to overeating. I am 4 years out from surgery and have lost 105lbs. Shortly after I start eating, I get a frontal headache, and it lasts for at least a 1/2 hour sometimes longer after eating. Anyone else finding this problem.

Have you already talked to a doctor? I believe the most common reason for this would be reactive hypoglycemia, but I'm sure there are other potential causes.

Only a doctor can properly diagnose the problem.
