I'm in beginning stage of band over bypass surgery and was wondering how long after can I fly

The problem isn't the surgery itself, the problem is the risk of blood clots after any surgery and being sedentary on long flights or car rides.

Check with your doctor to be sure and be prepared to walk around during the flight.

Regarding flying. It does seem to irritate my band. I hydrate and all but I have to be very gentle for the first day or so.

I have good luck with protein bars I order off the Internet. they don't "stick". I try for at least 15 grams of protein per bar. Around 150- 180 calories. Gotta find what works for you

I currently have a ivc filter I'm just wondering if the surgeon will frown upon flying
