Weight loss isn’t just about willpower—it’s a medical issue that can be approached safely, scientifically, and with professional guidance. If you’ve been considering medical weight loss programs, you probably have a lot of questions. Below, we answer the most common ones we hear from patients in Arizona who are exploring options such as FDA-approved medications like Semaglutide, Tirzepatide, and Phentermine.
What is medical weight loss?
Medical weight loss refers to a physician-supervised program designed to help patients lose weight safely and effectively. Unlike fad diets or over-the-counter supplements, medical weight loss involves:
A comprehensive health evaluation, including labs and medical history
Customized nutrition and activity recommendations
Prescription medications, if appropriate, to improve results
Ongoing monitoring by qualified healthcare providers
This approach ensures that your weight loss plan is safe, realistic, and tailored to your body—not a one-size-fits-all diet.
Who is a good candidate for medical weight loss?
You may be a good candidate if you:
Have a BMI over 27 with weight-related health conditions (like high blood pressure or diabetes), or a BMI over 30
Have struggled to lose weight through diet and exercise alone
Are seeking an evidence-based program rather than quick fixes
Medical weight loss isn’t just for “obesity”—it can also help prevent serious health issues in people who are overweight but not yet obese.
Which FDA-approved medications are used for weight loss?
Physicians typically prescribe one of several FDA-approved medications to assist with weight management:
Semaglutide (brand names like Wegovy®) – A GLP-1 receptor agonist that helps control appetite and improves blood sugar regulation.
Tirzepatide (brand name Mounjaro®) – A dual GLP-1/GIP receptor agonist showing impressive weight-loss results in clinical studies.
Phentermine – A long-standing appetite suppressant used in short-term weight loss plans, often combined with other therapies for greater effect.
These medications are not “magic pills.” They work best as part of a comprehensive plan that includes dietary changes, movement, and medical oversight.
How do Semaglutide and Tirzepatide help with weight loss?
Both drugs belong to a class of medications that regulate appetite and metabolism. Here’s how they work:
Semaglutide: Mimics GLP-1, a hormone that slows digestion, promotes fullness, and helps regulate blood sugar.
Tirzepatide: Activates both GLP-1 and GIP receptors, enhancing insulin sensitivity and appetite control. Clinical trials show patients often lose 15% or more of their body weight over several months.
Are there side effects? Are these medications safe?
Like any medication, these drugs can have side effects. The most common are:
Nausea, bloating, or diarrhea (usually temporary)
Rare cases of pancreatitis or gallbladder problems
For Phentermine: potential for increased heart rate or blood pressure, so it’s usually prescribed for short-term use under strict monitoring.
All of these medications are FDA-approved and considered safe when prescribed and supervised by a licensed medical professional. It’s critical to have follow-up appointments to adjust dosages and track your health markers.
How long do I need to take these medications?
Weight-loss medications are often prescribed for several months to a year, depending on your goals and your provider’s recommendations. Some patients transition off medications once they reach a healthy weight, while others stay on a maintenance dose. The goal is always sustainable, long-term results—not yo-yo dieting.
Can medical weight loss help with conditions like diabetes or high cholesterol?
Yes. Medications like Semaglutide and Tirzepatide were originally developed to treat type 2 diabetes and have been shown to:
Improve blood sugar control
Lower cholesterol and triglycerides
Reduce inflammation and metabolic risk factors
Even patients without diabetes often see improvements in blood pressure, energy levels, and overall health.
What’s the difference between Semaglutide, Tirzepatide, and Phentermine?

Do I still need diet and exercise if I’m on medication?
Absolutely. These medications help control hunger and cravings, but healthy lifestyle habits are what lock in your results. Your provider will help you design a plan you can realistically follow—no crash diets required.
Is medical weight loss covered by insurance in Arizona?
Coverage varies widely. Some insurance plans cover part of the cost, especially if you have obesity-related conditions. Others do not. Many clinics offer affordable self-pay options, and some provide financing to make treatment accessible.
How do I choose the right medical weight loss clinic?
Look for these signs of a reputable provider:
Board-certified physicians or nurse practitioners experienced in weight management
Personalized treatment plans rather than one-size-fits-all programs
Transparent discussion of risks, benefits, and costs
Consistent follow-up and patient education
Why choose a dedicated weight loss clinic instead of trying to do it alone?
A weight loss clinic provides more than just prescriptions—it offers structure, medical oversight, and accountability that make long-term success far more likely. Here’s why patients in Arizona prefer working with specialists instead of going it alone:
Medical evaluation first: Your provider identifies underlying issues (like hormonal imbalance or insulin resistance) that could make weight loss difficult.
Safe medication use: Only a clinic can prescribe and monitor FDA-approved medications such as Semaglutide, Tirzepatide, or Phentermine safely.
Tailored programs: Every patient gets a custom plan based on age, activity level, and overall health.
Ongoing support: Regular check-ins help track progress, adjust medications, and celebrate milestones.
Patients who work with a professional weight loss clinic tend to lose more weight and maintain their results longer compared to those who try generic online programs or fad diets.
What results can I realistically expect?
Every patient is different, but clinical studies show:
Semaglutide users often lose 10–15% of their body weight in 6–12 months.
Tirzepatide users may lose 15% or more.
Phentermine users typically lose weight more quickly in the first 8–12 weeks, though results vary.
Your progress will depend on your starting weight, your health profile, and how closely you follow your provider’s guidance.
