Weight loss injections have rapidly gained popularity as medically backed treatments that help patients lose significant weight by controlling appetite and boosting metabolism. The most effective weight loss injections belong to the class of drugs called GLP-1 receptor agonists, with some newer options also targeting additional hormones to enhance results.
Common Types of Weight Loss Injections
- Mounjaro (Tirzepatide)
- A dual agonist that mimics GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) hormones.
- Reduces appetite, improves insulin sensitivity, and enhances fat burning.
- Clinical trials show weight loss of up to 22.5% of initial body weight after 72 weeks with the highest dose.
- Wegovy (Semaglutide)
- A GLP-1 receptor agonist that regulates appetite and delays stomach emptying.
- Usually administered once weekly.
- Average weight loss in trials was around 15% of starting weight after 68 weeks.
- Saxenda (Liraglutide)
- Another GLP-1 receptor agonist taken daily.
- Helps reduce hunger and food intake.
- Results show average weight loss around 8% after 56 weeks.
How Effective Are These Injections?
- Weight loss injections are most effective at their maintenance doses combined with diet and exercise.
- Mounjaro has shown superior effectiveness due to its dual hormone action.
- Weight loss ranges typically between 8% and 22.5% of body weight depending on drug type and dose.
- They help reduce appetite, improve blood sugar control, and increase energy expenditure.
Common Side Effects
- Nausea, vomiting, constipation, diarrhea, and mild injection site reactions are typical but usually transient.
- Side effects often decrease after initial treatment weeks.
Choosing the Right Injection
- Selection depends on patient preference, medical history, frequency of dosing (weekly vs daily), and physician recommendation.
- Mounjaro and Wegovy are often preferred for weekly dosing and higher weight loss efficacy.
- These injectables require a prescription and clinical supervision.
