Appetite Suppressants: How They Work and Who Can Benefit
Appetite suppressants are a class of medications or supplements that help reduce hunger, increase satiety, and support weight loss. They are particularly useful for individuals struggling with obesity or those who need additional help beyond lifestyle changes such as diet and exercise.
How Do Appetite Suppressants Work?
These medications affect the central nervous system, altering the brain's perception of hunger. Many work by stimulating neurotransmitters like norepinephrine or serotonin, which contribute to a feeling of fullness. Some newer drugs, such as GLP-1 receptor agonists, also regulate appetite hormones in the gut.
Who Can Benefit From Appetite Suppressants?
Appetite suppressants may be prescribed for:
- Adults with a BMI over 30 (obese)
- Adults with a BMI over 27 and weight-related health conditions like type 2 diabetes or hypertension
- Patients who have struggled with traditional weight loss methods
Popular Prescription Options
- Phentermine
- Topiramate-Phentermine combo (Qsymia)
- GLP-1 agonists such as Semaglutide (Wegovy, Ozempic)
- Naltrexone-Bupropion (Contrave)
Potential Side Effects
As with all medications, appetite suppressants may cause side effects such as:
- Dry mouth
- Increased heart rate
- Constipation
- Insomnia or jitteriness
Newer medications like GLP-1 agonists tend to have gastrointestinal side effects such as nausea, which usually improve over time.
Safety and Precautions
These medications are not suitable for everyone. Patients with heart conditions, uncontrolled hypertension, or certain psychiatric disorders should be carefully evaluated. It’s essential to follow medical advice and undergo regular check-ups while using appetite suppressants.
Conclusion
Appetite suppressants can be powerful tools for weight management when used properly. They are most effective when combined with healthy eating, physical activity, and behavioral support. Always consult your doctor to determine the best option for your weight loss journey.
