A proven GLP-1 medication for lasting weight loss.
Semaglutide is a GLP-1 receptor agonist that mimics a naturally occurring hunger hormone — reducing appetite, slowing digestion, and improving blood sugar control. Clinical studies show an average of ~15% body weight reduction. Luma Health's compounded Semaglutide contains the same active ingredient as Ozempic® and Wegovy® — starting at just $90/month.
What Is Semaglutide?
Semaglutide is a prescription medication originally developed to help manage type 2 diabetes. Researchers later discovered that many patients taking semaglutide experienced significant weight loss — leading to its widespread adoption as a treatment for chronic weight management in eligible adults.
Semaglutide belongs to a class of medications known as GLP-1 receptor agonists. GLP-1 stands for glucagon-like peptide-1 — a naturally occurring hormone your body produces after eating that helps regulate blood sugar, digestion, and appetite. By mimicking this hormone, semaglutide helps patients feel fuller for longer and consume fewer calories throughout the day.
Luma Health's compounded Semaglutide contains the same active ingredient as Ozempic® and Wegovy® — physician-prescribed and personalized to your dose — starting at $90/month with free 2–3 day shipping. Prefer no injections? Try Oral Semaglutide instead.
How Does Semaglutide Work?
Many people assume semaglutide works simply by suppressing appetite — but its effects are considerably more complex. It influences multiple systems in the body simultaneously, making it one of the most comprehensive weight loss medications available today.
Semaglutide affects appetite centers in the brain — patients report feeling full faster, experiencing fewer cravings, less interest in snacking, and improved natural portion control.
By slowing gastric emptying, food stays in the stomach longer after eating — producing prolonged feelings of fullness between meals and reducing the urge to overeat.
Semaglutide helps the body release insulin more effectively when blood sugar rises — reducing energy crashes and hunger fluctuations that often contribute to weight gain.
Because semaglutide addresses multiple drivers of hunger and metabolism, it helps patients build sustainable habits — not just suppress appetite short-term.
How Much Weight Can You Lose on Semaglutide?
Clinical studies have shown that many patients achieve an average of approximately 15% body weight reduction when combining semaglutide with healthy lifestyle changes. That's roughly 30 pounds for someone starting at 200 pounds — a meaningful, life-changing outcome for most patients.
Results vary from person to person based on several factors:
- Starting weight and BMI
- Diet quality and consistency
- Exercise habits and activity level
- Sleep quality and stress management
- Consistency with weekly doses
- Underlying medical conditions
It's important to remember that semaglutide works best as a tool within a broader health plan — not as a replacement for healthy habits. Patients who commit to dietary improvements and regular movement tend to achieve the strongest and most sustainable results.
Semaglutide delivers ~15%.
Tirzepatide can reach up to 22%.
Both are highly effective — but if you're looking for maximum weight loss potential, tirzepatide's dual GIP/GLP-1 mechanism may deliver stronger results for some patients. Read our full comparison to understand which is right for you.

Common Side Effects of Semaglutide
Like any prescription medication, semaglutide can cause side effects — particularly during the early weeks of treatment or when your dose is increased. The good news is that most patients find these symptoms improve significantly as their body adjusts.
The most commonly reported side effects include:
- Nausea — most common early on, usually resolves within a few weeks
- Constipation or loose stools during dose transitions
- Mild stomach discomfort or bloating
- Decreased appetite — often the intended effect
- Occasional fatigue during early treatment
Your Luma provider starts you at the lowest effective dose and increases it gradually to minimize discomfort. Our FAQ page covers the most common questions about managing side effects on semaglutide.
How Long Does Semaglutide Take to Work?
Many patients begin noticing reduced appetite and fewer cravings within the first one to two weeks of treatment. Meaningful, measurable weight loss typically develops over several months as your dose is titrated and your body fully responds to the medication.
The most successful long-term outcomes typically involve:
- Consistent weekly injections as prescribed by your provider
- Nutrient-dense, protein-forward eating habits
- Regular movement and exercise most days of the week
- Quality sleep — 7 to 9 hours per night
