GLP-1 receptor agonists are associated with a higher frequency of gastrointestinal adverse events (nausea, vomiting, diarrhea) compared to placebo, although the risk of serious adverse events like pancreatitis remains comparable.
Expect gastrointestinal side effects like nausea and diarrhea when starting GLP-1 medications. These are common but usually mild to moderate. Serious side effects like pancreatitis are rare and occur at similar rates to placebo. Discuss management strategies with your provider to maintain treatment.

Across trials, GLP-1 RAs were consistently associated with a higher frequency of gastrointestinal adverse events compared to placebo, including nausea (14%–28% vs. 5%–10%), vomiting (6%–12% vs. 2%–4%), and diarrhea (8%–20% vs. 4%–7%). The risk of pancreatitis and serious adverse events remained comparable to placebo.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
