Semaglutide (Wegovy^® & Ozempic^®) for Weight Loss in Northern Virginia

Semaglutide — best known by the brand names Wegovy^® and Ozempic^® — has transformed medical weight loss, helping patients lose 12–15% of their body weight in clinical trials. At Virginia Bariatric Center in Herndon, semaglutide is prescribed and managed by Dr. Matthew Fitzer, a fellowship-trained, board-certified bariatric surgeon — not a med spa or an online questionnaire.

Dr. Fitzer’s experience using GLP-1s (and other medications) for weight loss began in 2005.¹ Experience matters. The best results come from pairing the right medication with real medical oversight, nutrition support, and a plan for what happens next. We serve patients throughout Northern Virginia and the Washington, D.C. metro area — including Herndon, Reston, Fairfax, Loudoun, Arlington, and Alexandria — with both in-office and telehealth visits.

What is semaglutide and how does it work?

Semaglutide is a GLP-1 receptor agonist. It mimics glucagon-like peptide-1, a hormone your gut releases when you eat. By activating GLP-1 receptors in the brain and digestive tract, semaglutide:

• Reduces appetite and quiets “food noise,” the constant background urge to eat
• Slows stomach emptying, so you feel full sooner and stay full longer
• Improves the body’s insulin response and blood-sugar control

The result is that eating less stops feeling like a constant fight with your own biology. Most patients take semaglutide as a once-weekly injection² with a small pre-filled pen, gradually increasing the dose over several months to minimize side effects.

Wegovy vs. Ozempic vs. the new Wegovy pill: what’s the difference?

All three contain the same active ingredient (semaglutide), but they are approved for different uses:

• Wegovy^® is FDA-approved specifically for chronic weight management (once-weekly injection, up to 2.4 mg).
• Ozempic^® is approved for type 2 diabetes; it is sometimes used off-label for weight loss, but insurance rarely covers it for that purpose.
• Oral Wegovy^® (semaglutide 25 mg tablet) — approved by the FDA as the first GLP-1 pill for weight loss — is a once-daily option for patients who prefer to avoid injections, with weight loss in the OASIS 4 trial comparable to the injectable.

Which version fits you depends on your health history, your insurance, and your preferences — exactly what we sort out at your first visit.

How much weight will I lose on semaglutide?

In the landmark STEP 1 trial, adults taking weekly semaglutide 2.4 mg lost an average of about 15% of their body weight over 68 weeks, compared with roughly 2% on placebo. For a 250-pound patient, that’s close to 40 pounds. About one in three patients in the trial lost 20% or more.

Individual results vary — genetics, dose tolerance, and lifestyle all play a role. It’s also worth knowing the honest comparisons: in the SURMOUNT-5 head-to-head trial, tirzepatide (Zepbound^®) produced greater average weight loss than semaglutide (20.2% vs. 13.7%), and bariatric surgery still delivers the largest and most durable results — typically 60 to over 70% of excess weight. Dr. Fitzer has written a detailed comparison in Wegovy vs. Surgery Outcomes. Because our practice offers the full spectrum, our only incentive is to recommend what will actually work for you.

Health benefits beyond the scale

Semaglutide is the most extensively studied weight-loss medication in history, and its benefits go well beyond weight:

• Heart protection. In the SELECT trial, Wegovy reduced major cardiovascular events (heart attack, stroke, cardiovascular death) by about 20% in adults with obesity and existing heart disease — and it is FDA-approved for this use.
• Liver disease. Wegovy is FDA-approved to treat MASH (metabolic dysfunction–associated steatohepatitis, or “fatty liver disease”) with moderate to advanced fibrosis.
• Blood sugar. Semaglutide improves A1c and can prevent progression from prediabetes to type 2 diabetes.
• Patients commonly report improvements in blood pressure, cholesterol, joint pain, sleep, and energy as weight comes down.

Who is a candidate for semaglutide?

You may qualify for semaglutide if you have:

• A BMI of 30 or higher, or
• A BMI of 27 or higher with at least one weight-related condition such as high blood pressure, type 2 diabetes, sleep apnea, or high cholesterol
• A BMI under 27 in selected circumstances.

Semaglutide is not appropriate for everyone. It should not be used during pregnancy, with a personal or family history of medullary thyroid carcinoma or MEN 2 syndrome, or with a history of pancreatitis without careful evaluation. Every new patient gets a full medical evaluation — not a checkbox form — before any prescription is written. Not sure where you stand? See Do I qualify? or simply request an appointment.

Side effects and safety: why supervision matters

Most side effects are digestive and improve as your body adjusts: nausea, constipation, diarrhea, and reflux are the most common, especially during dose increases. Occasionally, patients experience an odd tingling sensation or hypersensitivity of the skin. Less common but important risks include gallbladder problems, pancreatitis, and — the reason gradual dosing and follow-up matter — dehydration and rapid muscle loss when patients lose weight without adequate protein intake.

Dr. Fitzer follows the emerging research closely, including questions raised about rare eye conditions in GLP-1 users — see his plain-English review, Eye Problems and GLP-1 Meds: What We Know. Our program pairs your prescription with dietitian-guided nutrition (protein targets, hydration) and regular follow-up so weight loss is safe, not just fast.

Why get semaglutide from a bariatric surgeon?

Little-known fact: bariatric surgeons have more experience than anybody with managing weight-loss medications. Dr. Fitzer started prescribing the first GLP-1 medication (Byetta^®) in 2005. Bariatric surgery practice often forces surgeons to think outside the box to help patients with stubborn, resistant physiology reach their weight-loss goals — Dr. Fitzer has been at it for over twenty-one years now. Plenty of places in Northern Virginia will hand or digitally send you a semaglutide prescription. Here’s what’s different when your prescriber is a fellowship-trained bariatric surgeon leading a comprehensive weight-loss program:

• A plan for weight regain. Weight regain after stopping GLP-1s is the field’s biggest unsolved problem — Dr. Fitzer is three parts into his essay series on it. We’re thinking about your maintenance strategy from day one.
• Real medical management. Dose adjustments, side-effect management, lab monitoring, and coordination with your other physicians. When necessary, Dr. Fitzer and his staff actually talk to your doctor — on the phone!
• Team support. Dietitian, mental-health, and exercise guidance included in our program — the ingredients that separate 8% results from 15%+ results.
• Options if medications don’t deliver. If semaglutide doesn’t get you to your goal — or can’t maintain you there — we can escalate to tirzepatide, combination approaches, or even discuss surgical options. Med spas have a tool. We’re experts with all of them.
• Getting preauthorized. We have lots of experience overcoming denials. Dr. Fitzer has personally written reams of patient-specific appeal letters to overturn—very often successfully—a medication denial.

Cost and insurance coverage in Virginia

Coverage for Wegovy varies widely by plan and changes frequently. Many commercial plans cover it with prior authorization (which our office handles); Virginia Medicaid and some employer plans have their own rules; and as of 2026 a Medicare pilot program covers GLP-1s for weight management for eligible beneficiaries. For patients paying out of pocket, manufacturer self-pay programs have brought monthly costs down substantially from list price. We also prescribe affordable non-GLP-1 alternatives for patients whose insurance, budget, or medical history makes a GLP-1 less suitable. We walk every patient through their real options — start with our insurance coverage guide.
