At Prisk Orthopaedics and Wellness, PC, we understand the challenges associated with weight loss. While maintaining a healthy weight through diet and exercise remains the foundation, sometimes additional support is needed. Prescription weight loss medications can be a valuable tool in your weight loss journey, but it's important to understand their pros and cons before making a decision.
Understanding How Weight Loss Medications Work:
Our bodies have a complex system that regulates appetite, blood sugar, and metabolism. Many weight loss medications target these systems to promote weight loss in different ways. Here's a breakdown of some common mechanisms:
- Appetite Suppressants: These medications, like phentermine, work by affecting the central nervous system, increasing feelings of fullness and reducing hunger cues.
- GLP-1 Receptor Agonists: Medications like liraglutide (Saxenda) and semaglutide (Ozempic) mimic a natural gut hormone called GLP-1. GLP-1 signals satiety (fullness) to the brain, leading to decreased food intake and increased calorie burning.
- Lipase Inhibitors: Orlistat (Alli) works by blocking the enzyme lipase in the gut, preventing the absorption of some dietary fat.
- Dual Action Drugs: Newer medications like tirzepatide (Mounjaro) combine mechanisms. They target both GLP-1 and GIP (another gut hormone) receptors, offering a potentially more potent approach to weight loss.
Considering Weight Loss Medications: The Pros and Cons
Appetite Suppressants:
Pros:
- May lead to rapid weight loss in the short term.
- Relatively inexpensive compared to other medications.
Cons:
- Can cause side effects like anxiety, insomnia, and headaches
- Not recommended for long-term use due to potential for addiction and dependence.
- May not be effective for everyone.
GLP-1 Receptor Agonists:
Pros:
- Proven to be effective for long-term weight loss and maintenance.
- May improve blood sugar control in individuals with type 2 diabetes.
- May also offer other health benefits like lowering blood pressure and reducing the risk of heart disease.
Cons:
- Can be expensive, with high co-pays for some patients.
- Common side effects include nausea, vomiting, diarrhea, and constipation, which may subside over time.
- Injections required once a week.
- Not recommended for people with certain medical conditions, such as pancreatitis or a history of medullary thyroid cancer.
Lipase Inhibitors:
Pros:
- No reported effect on the central nervous system
- May be helpful for people who struggle with high-fat diets.
Cons:
- Can cause unpleasant side effects like oily stools, loose stools, and gas.
- May interfere with the absorption of fat-soluble vitamins (A, D, E, and K).
- Not as effective for weight loss as other medications.
Dual Action Drugs:
Pros:
- Early research suggests potentially greater weight loss than GLP-1 receptor agonists alone.
- May offer additional benefits like improved blood sugar control.
Cons:
- Newer medication, long-term safety data still being collected.
- Can be very expensive.
- Potential for side effects like those seen with GLP-1 receptor agonists and pancreatitis.
Important Considerations Before Taking Weight Loss Medications:
- Who is a candidate? Medications are most effective for people with a body mass index (BMI) of 30 or higher, or those with a BMI of 27 or higher with a weight-related health condition (e.g., type 2 diabetes).
- Safety first: Discuss your medical history with your doctor to determine if weight loss medications are safe, considering any existing conditions and medications you're already taking.
- Lifestyle changes are key: Weight loss medications are not a magic bullet. They work best when combined with a healthy diet and regular exercise.
- Realistic expectations: Weight loss typically occurs gradually with medication. Aim for a healthy rate of 1-2 pounds per week.
- Monitoring is crucial: Your doctor will monitor your weight, side effects, and overall health during treatment.
