Bariatric surgery is a major step, so I don't blame you for being scared. I just wanted to reach out and validate your feelings. I was scared, too, which is why I chose a non-surgical option (Endoscopic Sleeve Gastroplasty). It is not yet covered by insurance so it is not as popular, but in my experience thus far and per the medical literature it is safe & effective. Maybe ESG is something to keep in mind for later, if you still need a "tool" in the form of a sleeve. But I would wait until your weight stabilizes after the meds, exercise, and new healthy eating habits are established.
FWIW, I do not think your PCP is fat phobic. Obesity is a serious health risk, the older and the bigger you get. No one sees this more than a diligent PCP. Mine is 100% in favor of my new tool because she is the one who has been prescribing all my meds for hypertension and pre-diabetes, referring me to specialists, etc. I am just glad you went to see an endocrinologist and found a medical reason for your obesity.
In case no one else has said it lately, great job!! Even with new meds, losing that much weight is an accomplishment. I agree with the other suggestions here re: strength training and all. Best wishes to you.
