Bariatric surgery remains the most effective option for lasting weight loss, according to a new study that compared its outcomes with GLP-1 medications. Patients who underwent sleeve gastrectomy or gastric bypass lost around 24% of their body weight after two years, while those taking semaglutide or tirzepatide injections lost about 5% and 12 pounds on average.
The researchers analyzed data from over 38,000 people taking GLP-1 medications and 12,000 who had undergone bariatric surgery. They found that patients who received the surgery lost significantly more weight and achieved better long-term results than those taking the medications.
“We have to take the prescribing of GLP-1s much more seriously,” said Dr. Karan Chhabra, senior study author and a bariatric surgeon. “As more doctors are giving out these medications without careful oversight, I think we’re losing sight of the fact that surgery is still the best option for many people.”
However, experts acknowledge that GLP-1 medications can be an important tool for treating obesity, particularly for patients who don’t qualify for or can’t undergo bariatric surgery. These medications mimic hormones produced by the gut to signal fullness and can lead to significant weight loss.
“We’ve never had such a good obesity medicine,” said Dr. Shauna Levy, an obesity medicine physician. “However, up to 70% of people taking GLP-1s stop treatment within one year, which is why surgery remains the best option for long-term success.”
Ultimately, the decision between bariatric surgery and weight loss medications should be made with a doctor’s guidance, considering factors such as weight goals, preexisting conditions, and personal preferences.
