I agree. Everyone needs to do what's best for them. Frankly, you don't have to tell anyone anything. I don't discuss my health condition with anyone that doesn't need to know. When it comes to close family that loves me, they are going to notice significant difference in my lifestyle as well as my appearance (eventually), so I think it made sense to share this information with them.
P.S.
You are wrong about one thing though. In the medical professional labels matter and these procedures are being called "metabolic surgery", not just weight loss (or bariatric) surgery. That's why the American Society for Metabolic and Bariatric Surgery changed its name to add the term "Metabolic" a few years ago. This is the case because these procedures, which were originally popularized for weight loss benefits, are now being used to treat many different illness that are not necessarily related to obesity. Even the American Diabetes Association strongly supports the use of "metabolic surgery" to treat Type 2 Diabetes. This surgery is also used to treat very thin people that suffer from treatment resistant gastroparesis and other GI and metabolic illnesses. Sure, a large number of people are having these procedures done primarily because they are tired of being overweight, but to call it weight loss surgery does make it seem like "the easy way out" to the outside world. Metabolic surgery has a different connotation to the layman's mind as well as the minds of insurance companies. So, I suggest getting away for the use of the term "weight loss surgery" as much as possible.
