In recent years, obesity has become a significant public health challenge, with its prevalence steadily rising. Consequently, obesity medication is increasingly being recognized as a crucial part of medical weight loss strategies, complementing lifestyle interventions. Several FDA-approved medications have shown efficacy in managing obesity when combined with diet and exercise.
What Is Obesity Medication?
obesity medication are prescription drugs designed to help people achieve healthier body weight. They are typically recommended for individuals with a BMI ≥ 30 or those with a BMI ≥ 27 who also have obesity-related conditions such as diabetes, hypertension, or sleep apnea. Combining lifestyle modifications with these medications is often the most effective approach for sustainable weight loss.
When Is Medication Recommended for Weight Loss?
- BMI ≥ 30: Recommended for individuals with no other health issues.
- BMI ≥ 27 with comorbidities: Includes conditions such as diabetes, hypertension, and sleep apnea.
- When diet and exercise alone are insufficient: Medications can help kickstart weight loss efforts.
Types of Obesity Medication
GLP-1 Medications
GLP-1 medications like Semaglutide (Wegovy) and Tirzepatide (Zepbound / Mounjaro) work by controlling appetite and delaying gastric emptying.
Appetite Suppressants
Drugs like Phentermine and Phentermine-Topiramate are short-term solutions that help reduce appetite.
Fat Absorption Blockers
Orlistat reduces fat absorption in the digestive system, aiding weight loss by blocking calories from being absorbed.
Combination Medications
Naltrexone-Bupropion (Contrave) affects cravings and the reward centers in the brain, helping to manage food intake.
Prescription Pills vs. Injections
Both forms have their pros and cons. Pills are often easier to administer, while weight loss injections like those for GLP-1s can be more effective.
How Obesity Medications Work
These drugs operate by regulating appetite and hormones, enhancing metabolism, and improving blood sugar levels. They offer a science-backed approach to weight management.
Benefits of Prescription Obesity Medications
- Promote significant weight loss: Reduction of 10–20% body weight is achievable with GLP-1s.
- Reduce risk of chronic diseases: Decrease chances of diabetes, heart disease, and fatty liver.
- Boost energy and mobility: Enhancing physical function and self-esteem.
Potential Side Effects
- Nausea, bloating, constipation, and low appetite

Who Should Avoid Obesity Medication?
