Bariatric Surgery vs. Weight-Loss Injections

Clinical research shows that bariatric surgery typically leads to rapid and significant weight reduction, with most patients losing 40–44% of their total body weight within two years. Weight loss injections generally produce more gradual progress, averaging 15–17% total body weight loss over the same period.
