What is semaglutide?
Semaglutide is a prescription medication known as a GLP-1 receptor agonist. It acts like a hormone your body releases after eating, which helps control appetite and blood sugar. It is given as a once-weekly injection under the skin.
You may know semaglutide by a brand name. The FDA has approved it for weight management, and separately for type 2 diabetes. It is available by prescription only, so treatment starts with a medical evaluation.
How does semaglutide work for weight loss?
Semaglutide works by mimicking a natural GLP-1 hormone in your body to reset how you respond to food and hunger cues. By reducing appetite, muting persistent food noise, and slowing stomach emptying, it helps you feel naturally satisfied with smaller portions. At the same time, it enhances insulin sensitivity and may help address metabolic factors associated with insulin and leptin resistance, which can affect hunger, satiety, and weight regulation. These effects can make steady, manageable weight loss easier to reach.
At Onyx, semaglutide is paired with personalized nutrition and exercise rather than used as a standalone solution. Healthy lifestyle habits are built directly into your treatment plan from day one to help you protect lean muscle mass and maintain your results for the long term.
Weight is also influenced by thyroid function, medications, sleep, and hormonal changes. For patients receiving Comprehensive Care, your doctor can review your health history and lab work to look at these and other factors that may affect your progress.

Who may be a candidate for semaglutide?
Your doctor looks at the whole picture: your health history, your lab work, your current medications, and what has and has not worked for you before. Below are some of the reasons patients are prescribed semaglutide here.
- Where you are now
Weight that will not move
You have made real changes to how you eat and move, and the scale has not followed.
- Midlife
Perimenopause and menopause weight gain
Weight that arrived alongside the hormonal changes of your forties and fifties, often around the middle, and did not respond to what used to work.
- Lab work
Insulin resistance on your labs
Fasting insulin, glucose or A1c pointing to insulin resistance, whether or not your weight is high.
- Hormones
PCOS, also called PMOS
Polycystic ovary syndrome, now also called polyendocrine metabolic ovarian syndrome, where insulin resistance and weight are often part of the same picture.
- Body composition
A normal weight with high visceral fat
The scale can look fine while visceral fat sits around the organs. Body composition tells you more than weight alone.
- Related conditions
Sleep apnea and other weight-related conditions
Sleep apnea, high blood pressure, high cholesterol and type 2 diabetes are among the conditions that factor into the decision.
Semaglutide is not prescribed where there is a personal or family history of medullary thyroid carcinoma or MEN 2. Other conditions, and pregnancy, affect whether and when it is appropriate. Bring your current medication list and any recent lab work to your first visit. This page is a summary, not full prescribing information.
Benefits
Potential benefits of semaglutide
Weight loss is the main goal of semaglutide treatment. As weight and appetite change, some patients notice other things shift as well. Responses vary a lot from person to person, so your doctor tracks what actually happens for you rather than assuming any of this.
Easier portion control
Semaglutide helps you feel full sooner and stay full longer. Eating healthy portions can start to feel natural instead of a daily struggle against hunger.
Quieter food noise
Food noise is that constant thought in your head asking what you are going to eat next. Patients often tell us it goes quiet, and that it is the first change they notice.
Fewer cravings
You may find yourself reaching less for sugary snacks, alcohol or caffeine. Cravings that used to feel automatic lose some of their pull.
Healthier blood sugar
Semaglutide helps your body process sugar better. Your doctor tracks your blood sugar, A1c and other relevant markers as treatment goes on.
More regular cycles with PCOS
Some women with PCOS (also called PMOS) see their periods become more regular as their weight and insulin resistance improve.
Less joint pain
Taking extra weight off your frame means less stress on your knees, hips and back. Some patients notice they move around with less pain and stiffness.
Results
How much weight can you lose with semaglutide?
Everyone wants to know a specific number, but your results depend on where you start, your dose, and your daily habits.
1 to 1.5pounds a week, for most people
We aim for slow and steady weight loss, and we do it on purpose. Losing weight too fast usually means you are not eating enough food, and you start losing muscle along with the fat. Our goal is to keep you strong and healthy, so the result is one you can hold on to.
What studies show
In large medical studies, adults with overweight or obesity and without type 2 diabetes took weekly semaglutide alongside healthy habits. Results showed that 86% of participants lost at least 5% of their starting weight (about 10 lbs for a 200 lb adult), 69% lost at least 10% (about 20 lbs), and 50% lost 15% or more (about 30 lbs). Because everyone's body responds differently, your doctor will help you set realistic goals for your health. (Source: Wilding JP et al., NEJM 2021)
What to expect
What to expect during semaglutide treatment
Treatment follows the same general path, adjusted to how you respond. Some people notice appetite changes in the first few weeks, and weight loss builds gradually as the dose is adjusted. Your dose, schedule and how long you stay on treatment are decided with your doctor.
01
Your first visit and lab work
We review your health history, medications, goals, and past challenges with weight. Your doctor may order lab work when appropriate to better understand your health and identify factors that may affect your weight and treatment plan.
02
Starting treatment
You start with a low dose to help your body adjust to semaglutide. We show you how to give the once-weekly injection at home and check how you are responding, including changes in appetite, cravings, food noise and any side effects.
03
Adjusting your treatment
Your doctor may slowly increase your dose, usually no sooner than every four weeks, based on how you are responding and tolerating treatment. We also follow your labs, nutrition, eating habits and weight progress while working with you to address obstacles that may make it harder to reach your goals.
04
Ongoing care & long-term maintenance
Our goal is to help you maintain your results, not just lose weight while taking medication. We continue to support your nutrition and overall health while planning for the future, which may include gradually tapering the medication, staying on a lower maintenance or microdose, or using another approach that fits your needs.
Semaglutide vs. other GLP-1 medications
Semaglutide is one of several medications used for weight management. They work through related pathways but are not interchangeable. The right option depends on your health history, goals, response, tolerability and other factors. Onyx prescribes tirzepatide as well, and our tirzepatide in Gilbert, AZ page covers that option in the same detail.
| Compared on | Semaglutide | Tirzepatide |
|---|---|---|
| How it is taken | Once-weekly injection | Once-weekly injection |
| FDA-approved for weight management | Yes | Yes |
| Primary mechanism | GLP-1 receptor agonist | GIP and GLP-1 receptor agonist |
| Key difference | Weekly injection with the largest body of weight-management trial data | Acts on both GIP and GLP-1 receptors |
Note: Onyx prescribes the once-weekly injection. Oral semaglutide absorbs poorly and produces weaker results, so the injection is the reliable option.
Weight-loss study results vary depending on dose, length of treatment, and individual health factors. There is no single best medication for everyone. Your doctor will help select the best starting point and can adjust your plan if your needs change over time.

Frequently Asked Questions
Semaglutide
Is semaglutide the same as Ozempic?
Yes and no. Ozempic is a brand of semaglutide approved for type 2 diabetes. Semaglutide is approved for weight management as well, at a different dose, so it is the same medicine used a different way. The two are not interchangeable. What we prescribe here is compounded semaglutide from a pharmacy we have vetted, not a brand-name product, and it is an out-of-pocket expense either way.
How is semaglutide taken, and does it hurt?
It is a quick weekly injection given under the skin with a very fine needle. Most people say it is a brief pinch rather than something that hurts. We walk you through the exact steps so you feel confident doing it yourself at home.
What are the side effects of semaglutide?
The most common side effects are stomach related: nausea, an upset stomach, constipation or diarrhea. They usually show up when you start or when your dose goes up, and they tend to settle as your body adjusts. We give you practical ways to manage them. More serious problems are uncommon. They include pancreatitis, gallbladder problems, dehydration and low blood sugar. Your doctor goes through the signs to watch for, and when to call, before you start and at every follow-up.
How long do I need to stay on semaglutide?
There is no set deadline. Weight care is an ongoing journey, and stopping usually brings your appetite back along with some degree of weight regain. We work with you on a long-term plan, whether that means staying on a low maintenance dose or slowly tapering off once you reach your goals.
Will I lose muscle on semaglutide?
Any time you lose weight, your body can lose some muscle along with fat. To help keep you strong, our team helps you focus on eating enough protein and adding simple strength exercises to your routine.
What does semaglutide cost, and does insurance cover it?
Onyx is a self-pay clinic. Insurance does not cover weight-loss medication, so this is an out-of-pocket expense: your first visit, the medication, any lab work you need and your follow-ups. Both the office visit and the medication are billed by us, not by a pharmacy, and we fill through a small number of compounding pharmacies we have vetted. You get a clear, itemized cost breakdown at your consultation, with no hidden fees. Call us at (480) 531-2557 to talk through pricing.
Can I get semaglutide without a doctor visit or lab work?
No. Semaglutide is a prescription medication, so a doctor has to evaluate your health first. We review your medical history and order lab work when it is needed, to make sure this treatment is appropriate for you.
Is semaglutide available through telemedicine?
Yes. We see telemedicine patients nationwide. Once your first health evaluation is done, your routine follow-up visits can be handled from your phone or computer.
