2 weeks after umbilical hernia repair, can't eat as much. get full much faster than before. used to eat 1 cup oatmeal (dry meas.) before bed. some days, more. now, it makes me too full. is this ok?

Discuss with your : Surgeon. It's usually stomach surgery that would affect the appetite and not hernia or intestinal operation. Could just be psychological. If you're losing weight with vomiting and diarrhea , go follow up with your dr right away!

Go back to doctor: See the surgeon who performed the procedure and have them examine you for potential complications. Good luck.

Probably: There are a variety of symptoms after an operation that ate likely due to the trauma of the operation and/or the anesthesia, especially if it was general anesthesia. These are highly variable, and usually wane with time. It doesn't sound serious, but call you surgeon if it persists, or gets worse.
