Hi there, Rae, you got it just right. I would stay away from any carbonated drinks of any kind. The enemy of the post-surgery belly is gas! The exquisitely... not in a good way! Maybe take the cap off and get rid of the gas before drinking... flat beer is no fun. A nice glass of Pinot Noir would be much better and safer.
Not trying to scare you, Miss Worrier, but... I had a gas bubble in the hospital after reversal and it was really scary. I kept telling the nurse and docs that I had to have an NG tube in my stomach but they wouldn't listen. I had my past experiences to go by and I knew. After a day (at least) of absolute agony, they decided that I was right. The nurse wound up climbing on top of me in the bed, hands shaking, in a total very scary panic trying to feed the NG up my nose as I was almost passing out from pain. It took quite a while as I had to swallow constantly to help the tube down my throat.
When the tube broke through and entered my stomach, the container to which the tube was attached filled up in a split second and looked like it was going to explode with the volume. My belly had been like 6 months pregnant before and it looked like a balloon just deflated inside me as my belly assumed its normal shape! That was the first and only time I was ever really scared in the hospital.
Nurses out there, please listen to your patient, they will often know a lot more about their condition and, in particular, how their body reacts to certain events than the nurse does. As with me... been there before and have the terrifying memories to prove it!!!
If you begin feeling pressure, enough to swell your belly, then pay attention to increases in pressure. If it ever gets painful and feels a bit like a drum when you tap with your finger, then do not hesitate to go to the ER. It can escalate pretty quickly, so take it seriously.
Meanwhile, have a nice glass of Vin Rouge... good for your blood.
Stay safe and I hope you don't need the drumsticks!!! Eamon
