Hey there,

Welcome to this week’s edition of SemicHealth Pulse.

If you’ve been following the latest in weight loss trends, you’ve probably heard about Semaglutide, also known as Wegovy, the “weight loss shot” that’s changing the game.

Originally designed to treat type 2 diabetes, Wegovy is now FDA-approved for chronic weight management in adults who are overweight or obese, even if they don’t have diabetes.

But how does it work? Who can use it safely? And what kind of results can you expect?

In today’s newsletter, we’ll cover:

  • What Semaglutide is and how it works

  • Who it’s approved for and what studies show

  • The right dosage and how to use it

  • Side effects to watch out for and what to do

What Exactly Is Semaglutide (Wegovy)?

Semaglutide mimics a natural hormone in your body that helps regulate blood sugar, hunger, and digestion.

When used in higher doses than those for diabetes, Semaglutide helps you feel fuller for longer, reduces cravings, and slows down digestion, all of which can lead to significant weight loss.

It’s available as a once-weekly injection, and unlike short-term diet fixes, it’s designed to support long-term weight management.

Who Can Use Wegovy for Weight Loss?

The Food and Drug Administration has approved Wegovy (Semaglutide 2.4 mg) for adults who:

  • Are obese (BMI ≥ 30), or

  • Are overweight (BMI ≥ 27) with at least one related health condition like high blood pressure, high cholesterol, or type 2 diabetes.

It’s also approved for children aged 12 and above who struggle with obesity.

Clinical studies, like the STEP trials, found that people using Semaglutide along with diet and exercise experienced significant and sustained weight loss. In one study, participants lost an average of 15% of their body weight over a year.

That’s not just a small difference, it’s a game-changer.

The Right Dosage and How Semaglutide Works

Semaglutide works by:

  • Slowing down digestion so you feel full longer.

  • Suppressing appetite by acting on areas of the brain that control hunger.

  • Reducing cravings for high-calorie foods.

  • Stabilizing blood sugar levels prevents energy crashes that often trigger overeating.

Together, these effects make it easier to maintain a calorie deficit without feeling deprived or constantly hungry.

The Right Dosage for Non-Diabetics

For weight loss, the recommended dose is 2.4 mg once weekly. It’s important to start small and increase gradually over several weeks to minimize side effects like nausea.

Pro Tip: Always follow your doctor’s schedule for dosage adjustments, don’t rush it. Regular check-ins will help you monitor progress and manage any side effects early.

Side Effects To Watch Out For and What To Do

While many people tolerate Semaglutide well, it’s not without potential side effects. The most common include:

  • Nausea or vomiting

  • Diarrhea

  • Reduced appetite

  • Mild low blood sugar

  • Redness or swelling at the injection site

These symptoms usually improve as your body adjusts. Still, if you experience severe or persistent discomfort, contact your doctor immediately.

Healthy eating, regular exercise, and consistent medical guidance are still the foundation of sustainable weight loss. Semaglutide simply makes the journey easier for those who’ve struggled to manage weight with lifestyle changes alone.
