GLP-1 medications have gone from a niche diabetes treatment to one of the most talked-about tools for weight management, and Phoenix-area adults have plenty of questions about how they work, who they are for, and what to expect. Here are clear, physician-reviewed answers.
A GLP-1 medication is a prescription drug that mimics a gut hormone to reduce appetite, slow stomach emptying, and, in people with type 2 diabetes, improve blood sugar. If you live in Phoenix, Scottsdale, Tempe, Mesa, Chandler, Glendale, or Gilbert, these are the questions patients ask most often.
Key Takeaways
Wegovy and Zepbound are FDA-approved for chronic weight management, while Ozempic and Mounjaro are approved for type 2 diabetes.
These medications are prescribed after a medical evaluation and are not right for everyone.
Digestive side effects are common, and a boxed warning covers the risk of thyroid C-cell tumors.
Results vary, and stopping treatment often leads to some weight regain.
How Do GLP-1 Medications Work?
They act on receptors for GLP-1, a hormone released after eating. This helps you feel full sooner, slows how fast food leaves the stomach, and helps the pancreas release insulin when blood sugar is high. Tirzepatide also targets a second hormone, GIP. Most are injected once a week, and oral options exist too.
Who Is a Candidate?
FDA labeling for weight-management medications generally covers adults with a BMI of 30 or higher, or 27 or higher with a weight-related condition, alongside nutrition and activity changes. Physicians also screen for safety concerns. GLP-1 medications should not be used by anyone with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, and they are not used in pregnancy. Review the approved labeling for Wegovy on the FDA's Drugs@FDA database.
How Much Weight Do People Lose?
In the STEP 1 trial, adults taking semaglutide 2.4 mg with lifestyle intervention lost an average of 14.9% of body weight over 68 weeks, compared with 2.4% on placebo. In the SURMOUNT-1 trial, tirzepatide produced average losses of up to about 21% at the highest dose over 72 weeks. Individual results vary widely, and trial participants received structured support.
What Are the Side Effects?
Nausea, diarrhea, vomiting, and constipation are the most common, especially when a dose starts or increases. Rarer risks include pancreatitis, gallbladder problems, and dehydration. In Arizona's heat, keeping up with fluids is especially important. Contact your provider for severe stomach pain or if you cannot keep fluids down.
What Happens if I Stop?
Obesity is a chronic condition, and many people regain some weight after stopping. Talk with your physician before making changes so you can plan for maintenance.
Are There Alternatives?
Yes. TeleSlim Clinic Phoenix also offers liraglutide (Saxenda), phentermine, phentermine-topiramate (Qsymia), naltrexone-bupropion (Contrave), orlistat, and metformin, along with setmelanotide for rare genetic causes of obesity after genetic confirmation. Explore them on the weight loss medications page. TeleSlim Clinic does not prescribe compounded medications, which the FDA does not review for safety, effectiveness, or quality.

Frequently Asked Questions
Is a GLP-1 the same as Ozempic?
No. Ozempic is one brand of semaglutide approved for type 2 diabetes. GLP-1 refers to the drug class.
Do I need diabetes to get a GLP-1 for weight loss?
No. Wegovy and Zepbound are approved for weight management in adults who meet the criteria, without requiring diabetes.
How long will I be on treatment?
It varies. Because obesity is chronic, many people continue treatment long term. Your physician will review your plan regularly.
Is it safe to buy GLP-1 medications online from any site?
No. Use a licensed prescriber and a licensed pharmacy, and be cautious of products marketed as a cheap "generic," since there is no FDA-approved generic semaglutide or tirzepatide.
Will insurance pay for it?
Coverage varies by plan and diagnosis. The TeleSlim Clinic visit fee is cash-pay, and you can ask your insurer about medication coverage.
