What Is Semaglutide?

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist originally developed to treat type 2 diabetes. It gained widespread attention when clinical trials showed significant weight loss results in people without diabetes.

How It Works

GLP-1 is a hormone your gut naturally releases after eating. It signals your brain that you're full, slows stomach emptying, and regulates insulin secretion. Semaglutide mimics this hormone — but lasts much longer in your body.

The result: reduced hunger, smaller appetite, and a lower caloric intake without feeling deprived.

Clinical Evidence

In the STEP 1 trial, participants taking semaglutide 2.4 mg weekly lost an average of 14.9% of their body weight over 68 weeks, compared to 2.4% with placebo.

That's not a small effect. For a 220-pound person, that's roughly 33 pounds.

Who Might Benefit

Semaglutide may be appropriate for adults who:

  • Have a BMI ≥ 30, or ≥ 27 with a weight-related health condition
  • Have struggled with diet and exercise alone
  • Do not have a personal or family history of medullary thyroid carcinoma

Common Side Effects

Most side effects are gastrointestinal and tend to improve over time:

  • Nausea (most common, especially early on)
  • Vomiting
  • Diarrhea or constipation
  • Reduced appetite

Starting at a low dose and titrating slowly significantly reduces these effects.

The Bottom Line

Semaglutide is a powerful clinical tool — not a magic solution. It works best combined with lifestyle changes: a protein-rich diet, regular movement, and adequate sleep. CuraVita's clinical program pairs provider oversight with ongoing support to maximize outcomes safely.
