1. Understanding Weight-Loss Injectables
Weight-loss injections are typically glucagon-like peptide-1 (GLP-1) receptor agonists, which help regulate appetite and insulin levels. By mimicking natural hormones in the body, these injectables can reduce hunger, improve blood sugar control, and promote a feeling of fullness after eating.
- Mechanism of Action: Slows gastric emptying and reduces appetite.
- Common Drugs: Wegovy, Ozempic (both semaglutide) and Saxenda (liraglutide).
- Approval Status: Many of these medications are FDA-approved for weight management in individuals with specific body mass index (BMI) criteria.

Semaglutide (Wegovy, Ozempic)
- Manufacturer: Novo Nordisk

Like any prescription medication, weight-loss injectables come with potential side effects and risks. Some common considerations include:
