My sister was very Ill like you after being sleeved. Ended up having a hematoma...the size of a football...pressing on her stomach forcing all liquid to be thrown up. Very serious...she had kidney failure....they put 2 drains in to reduce the size of the clot...then she got better. Been a year since her surgery she has lost 100 lbs and doing very well. I would ask if they can check and see if you are having the same issue...hope this helps. Prayers for you
