The Claim

In non-diabetic adults with overweight or obesity, once-weekly semaglutide at a dose of 2.4 mg is associated with transient, mild-to-moderate gastrointestinal adverse events, most commonly nausea (44.2%), diarrhea (31.5%), and vomiting (24.8%), with 4.5% discontinuing treatment due to gastrointestinal events compared to 0.8% in the placebo group.

In plain English

People without diabetes who are overweight or obese and take a weekly 2.4 mg dose of semaglutide often get mild stomach issues like nausea, diarrhea, or vomiting, but most keep taking it — only a small number stop because of these side effects.

Once-weekly semaglutide at 2.4 mg is associated with transient, mild-to-moderate gastrointestinal adverse events in non-diabetic adults with overweight or obesity, with nausea (44.2%), diarrhea (31.5%), and vomiting (24.8%) being most common, leading to treatment discontinuation in 4.5% due to GI events, compared to 0.8% with placebo.

What the research says

1 study
  1. Study: Once-Weekly Semaglutide in Adults with Overweight or Obesity.

    The study looked at the same medicine and dose as the claim and found similar stomach-related side effects that were usually mild and went away over time, with slightly more people stopping the drug because of these issues compared to placebo.
