TL;DR: GLP-1 medications like Ozempic and Wegovy mimic a gut hormone to suppress appetite, slow digestion, and improve blood sugar, shifting obesity care from lifestyle blame to biology-based treatment. Their global impact comes from scaling this clinical model throughprescribing pathways, supply management, and payer reform.
1. Understand the Mechanism Before You Prescribe or Pursue It
GLP-1 receptor agonists copy glucagon-like peptide-1, a hormone released after eating. They slow gastric emptying, reduce appetite signals in the brain, and boost insulin release. Ozempic (semaglutide) is approved for diabetes; Wegovy (higher-dose semaglutide) is approved for obesity. Know the distinction before discussing treatment.

2. Confirm Eligibility With Objective Measures
Most guidelines support GLP-1 therapy for adults with a BMI of 30 or higher, or 27 or higher with at least one weight-related condition such as hypertension, sleep apnea, or type 2 diabetes. Document these numbers. Insurance and public payers increasingly require them.
3. Build a Titration and Monitoring Plan
Start at the lowest dose and increase every four weeks as tolerated. Common side effects include nausea, vomiting, diarrhea, and constipation. Advise smaller meals, hydration, and reduced fat intake. Monitor for pancreatitis, gallbladder disease, and rare thyroid concerns. Never stop or restart abruptly without clinical guidance.
4. Address Supply, Cost, and Equity
Global demand has caused shortages. Prioritize patients with the highest clinical need. Explore compounded semaglutide only where legally permitted, and warn patients about unregulated online sellers. Work with payers on prior authorization and consider telehealth follow-up to extend reach.
5. Integrate Lifestyle and Long-Term Support
GLP-1s work best alongside nutrition counseling, resistance training, and behavioral support. Weight regain often follows discontinuation, so plan for maintenance dosing or alternative strategies. Track cardiovascular markers, not just scale weight.
6. Scale the Model Globally
Low- and middle-income countries face price and cold-chain barriers. Advocate for tiered pricing, generic semaglutide as patents expire, and national obesity registries. Train primary care clinicians to reduce specialist bottlenecks.
FAQ
Q: Are Ozempic and Wegovy the same drug?
A: Both contain semaglutide, but Wegovy uses a higher maximum dose approved specifically for obesity, while Ozempic is approved for type 2 diabetes.
Q: Can I stop GLP-1s once I lose weight?
A: Many patients regain weight after stopping, so long-term maintenance plans, dose reduction, or lifestyle reinforcement are usually needed.
Q: Do GLP-1s replace diet and exercise?
A: No. They reduce appetite and improve metabolic control, but nutrition, activity, and behavioral support remain essential for lasting results.
