"I’m not anti-medication.
I’m anti-confusion.

Ozempic, Wegovy, and Zepbound can absolutely help the right patient.
But they are not a permanent replacement for bariatric surgery.

If you want honest answers, you need honest comparison.

Weight regain after bariatric surgery is not a character flaw. It’s biology.
Hormonal shifts, anatomical changes, and metabolic adaptation can work against even the most disciplined patients. That’s why revisional surgery exists — and why it’s now one of the most commonly performed bariatric procedures in America.
If your first procedure didn’t give you the lasting results you hoped for, you’re not alone — and you’re not out of options.
