Since my 2015 sleeve, I have developed severe Gerd and also have a hernia so I’m converting to a bypass in June. I went to the pulmonary dr the other day and did a battery of breathing tests and said I nailed them very close to 100%. I’m thrilled since I quit smoking 20 years ago and he said no sign of lung damage at all. Next thing I know I have to come back to pick up a machine for a sleep study? I don’t understand why. I feel like that are tacking on extras. I never had this before. I asked why and he said it’s because your going under anesthesia. Not to argue with him but I said I just had a hysterectomy less that a year ago and that was 5 hours under. No sleep study......This is a 1/2 hr at most. What’s your experience?

Sleep apnea is common in overweight people. Test is easy. :-)

Most bariatric surgeons want each patient to have the cpap machine. Anesthesia can be tricky for anyone, let along an overweight person. It just helps with recovery as well.

I has trace of sleep apnea which means it was barely detected during my test but the docs said I had to have it since I was going through the bariatric program

Curious that you did not need a sleep study for sleeve surgery...

It's just a precaution to make sure you can breathe while under general anesthesia if you have sleep apnea
