Real-world use of semaglutide for weight loss (SEMA-WL) in adults with obesity results in median weight loss of 17% after >5 months of treatment, with nausea and constipation being the most common side effects.

If you have obesity and are considering semaglutide, expect significant weight loss (around 17% after 5+ months) but also common side effects like nausea and constipation. Most users find self-injection manageable, though some prefer a pill. Talk to your doctor about managing side effects and setting realistic expectations.
