Semaglutide helps people who are overweight or obese lose weight by making them feel less hungry and slowing down how fast food leaves their stomach.
Taking a weekly injection called semaglutide along with healthy eating and exercise can help people with obesity or overweight lose about 15% of their body weight in a year—much more than people who just take a sugar pill.
When adults with obesity take a drug called semaglutide 2.4 mg for about 1.5 years, nearly 9 out of 10 lose at least 5% of their body weight — compared to only about 1 in 3 to half of those taking a sugar pill or another drug, meaning semaglutide works better for weight loss in most people.
When people take semaglutide 2.4 mg, many feel sick to their stomach, throw up, or have constipation or diarrhea—but very few stop taking it because of these side effects.
Don't take this weight-loss drug if you or a close family member ever had a certain type of thyroid cancer, because it caused tumors in mice and rats—even though we haven't seen that happen in people yet.
