The Claim

Once-weekly subcutaneous semaglutide 2.4 mg is associated with a higher incidence of gastrointestinal adverse events (nausea, vomiting, diarrhea, and constipation) compared to placebo in patients with metabolic dysfunction-associated steatohepatitis (MASH) and fibrosis stage 2 or 3, with no increase in serious adverse events.

In plain English

Patients with MASH and moderate liver fibrosis who take weekly semaglutide injections have more gastrointestinal side effects like nausea and diarrhea than those taking a placebo. However, the rate of serious adverse events is not higher with semaglutide.

See the scientific wording

Gastrointestinal adverse events (including nausea, vomiting, diarrhea, and constipation) are more common with once-weekly subcutaneous semaglutide 2.4 mg than with placebo in patients with MASH and fibrosis stage 2 or 3, consistent with the known safety profile of GLP-1 receptor agonists, though no increase in serious adverse events was reported.

Why this might work

Semaglutide slows down stomach emptying and makes you feel full longer by activating receptors in the gut and brain. This causes the stomach to empty slowly, leading to nausea and vomiting, and can also affect bowel movements causing diarrhea or constipation.

  1. Study: Phase 3 Trial of Semaglutide in Metabolic Dysfunction-Associated Steatohepatitis.

    The study found that people taking semaglutide had more stomach-related side effects like nausea and diarrhea than those on placebo, just like the claim says. This is expected for this type of medicine.
