I had my sleeve surgery 2/20/17 spent one day in hospital. Home now the first thing I did was weigh myself. I was heavier this morning post surgery. Maybe it because of all the IV fluids and gas pumped in my abdomen? I have cramps how long will this feelings of bloating last?

Yes, very common to come home weighing more due to the fluids. It may take a few days but the excess will flush itself out. I was up like 8 lbs when I got home.

Gas build up is a major pain in arse the first few days. Getting up and moving around is one of the best things to do to help get it out of your system. Everybody is different but generally it seems the first 3-4 days are the worst. Don't worry...it does get better! Just walk, walk, walk!
