Weight loss medications, often referred to as anti-obesity drugs, can be an effective part of a comprehensive weight management plan for individuals who struggle with obesity or are overweight and have not had success with diet and exercise alone. Here’s an overview of common types of weight loss medications, their mechanisms, and considerations:
Common Types of Weight Loss Medications
- Appetite Suppressants : These medications help reduce hunger and control cravings.
- Examples :
- Phentermine: A stimulant that acts similar to an amphetamine, it works to suppress appetite.
- Diethylpropion: Another appetite suppressant that is generally prescribed for short-term use.
- Examples :
- Fat Absorption Inhibitors : These medications work by blocking the absorption of dietary fat in the intestines.
- Example :
- Orlistat (Alli, Xenical): This medication inhibits the enzyme lipase, which is necessary for fat digestion, leading to a reduction in calorie intake from fats.
- Example :
- Glucose Regulation : Some medications initially designed for diabetes management can also promote weight loss.
- Examples :
- GLP-1 receptor agonists (e.g., Liraglutide [Saxenda], Semaglutide [Wegovy]): These medications help increase insulin secretion, decrease appetite, and slow gastric emptying.
- Examples :
- Combination Medications : Some weight loss medications combine two or more different mechanisms to help reduce weight.
- Example :
- Phentermine/topiramate (Qsymia): This combination medication reduces appetite and also has anti-seizure properties.

Effectiveness
- Weight loss medications can lead to a modest weight loss, typically between 5% to 10% of total body weight over a year. The effectiveness may vary by individual, and they usually work best in conjunction with lifestyle changes such as diet and exercise.
Safety and Side Effects
- Common Side Effects : Vary by medication but can include nausea, constipation, diarrhea, insomnia, headaches, and elevated heart rate.
- Contraindications : Not all individuals are candidates for weight loss medications. People with certain medical conditions (e.g., heart disease, uncontrolled high blood pressure) or women who are pregnant or breastfeeding may be advised against their use.
- Long-term Use : Some weight loss medications are intended for short-term use, while others can be part of a long-term weight management strategy.
Consultation with a Healthcare Provider
- Before starting any weight loss medication, it’s essential to consult with a healthcare provider. A thorough assessment of health status, weight history, and possible interactions with other medications is necessary to determine the most appropriate treatment options.
