The GLP-1 Revolution in Weight Management
Glucagon-like peptide-1 (GLP-1) receptor agonists are transforming how physicians treat obesity. Medications like semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro, Zepbound) have produced weight loss results that were previously achievable only through bariatric surgery. At Mediversity in Turnersville, NJ, our physicians are prescribing these medications as part of comprehensive, medically supervised weight loss programs.
How GLP-1 Medications Work
GLP-1 is a hormone naturally produced in your gut after eating. It signals to your brain that you are full and tells your pancreas to release insulin. GLP-1 receptor agonists mimic and amplify this signal. The effects include:
- Dramatically reduced hunger and appetite
- Prolonged feeling of fullness after meals
- Slowed gastric emptying (food moves through your stomach more slowly)
- Improved blood sugar regulation and insulin sensitivity
- Reduced cravings, especially for high-calorie foods
Semaglutide vs. Tirzepatide: What Is the Difference?
Semaglutide (Wegovy) is a GLP-1 receptor agonist that targets one receptor pathway. Tirzepatide (Zepbound) is a dual GIP/GLP-1 agonist — it activates two pathways simultaneously. Clinical trials show tirzepatide produces slightly greater average weight loss (up to 22% vs. 15–20% for semaglutide), though individual responses vary. Your physician will recommend the most appropriate option based on your health profile and treatment goals.
Who Qualifies for GLP-1 Weight Loss Medications?
FDA-approved GLP-1 medications for weight loss are indicated for adults with:
- BMI ≥ 30 (obesity)
- BMI ≥ 27 with at least one weight-related condition (hypertension, type 2 diabetes, dyslipidemia, sleep apnea)
Important contraindications include: personal or family history of medullary thyroid carcinoma, Multiple Endocrine Neoplasia syndrome type 2, or serious GI disorders. A thorough physician evaluation is essential before starting.
What Side Effects Should You Expect?
GLP-1 medications are generally well-tolerated when doses are introduced gradually. Common side effects include:
- Nausea: The most common — typically mild and temporary, occurring mainly when the dose is increased
- Vomiting and diarrhea: Affect a minority of patients; usually self-limiting
- Constipation: Can occur due to slowed gut motility
- Reduced appetite: This is actually the desired effect, but some patients eat too little initially
Our physicians use a slow dose escalation protocol — starting at the lowest dose and increasing every 4 weeks — to minimize these effects. Most patients find side effects manageable and temporary.
How Long Do You Stay on GLP-1 Medications?
This is an important question. GLP-1 medications are most effective as long-term treatments. Studies show that patients who stop taking them often regain significant weight within a year, because the underlying hormonal environment reverts. The medications work best as part of a comprehensive lifestyle program. Your physician will work with you on a long-term strategy that may include eventual dose reduction as you reach and maintain your goal weight.
Cost and Coverage
GLP-1 medications can be expensive without insurance coverage. Wegovy and Zepbound have manufacturer savings programs. Some insurance plans cover them when prescribed for qualifying conditions. Our team at Mediversity can help navigate coverage options and connect you with patient assistance programs when available.
