Semaglutide 2.4 mg/week induces significant weight loss in patients with severe obesity, including those with a history of bariatric surgery, achieving outcomes comparable to or exceeding those of non-surgical patients.

If you have severe obesity, even if you have had weight loss surgery before, a weekly injection of 2.4 mg semaglutide can still help you lose weight. It is not a wasted effort due to your surgical history.
