Which of these branches of medicine deals with obesity?

Son had bariatric surgery 10 days ago . The surgery is the easy part . It’s the lifestyle and mental attitude change that is harder.

I thank the Lord my God I'm not overweight!!! ( I have a super model body no kidding I do!!)

I had bariatric surgery. Best decision of my life!!

A person being g over weight is never funny.

I need it on a waiting list
