Understanding Weight Loss Medications: Insights from Dr. Janese Laster
In a recent discussion hosted by AMA Chief Experience Officer Todd Unger, Dr. Janese Laster, a gastroenterologist and obesity medicine specialist, addressed common questions about weight loss medications. This article summarizes key points regarding the types of drugs available, their mechanisms of action, insurance coverage, and the necessity of lifestyle changes for effective weight management.
Overview of Weight Loss Medications
Dr. Laster highlighted several weight loss medications, including:
- Older Oral Agents:
- Qsymia: A combination of phentermine and topiramate that increases metabolic rate and promotes satiety.
- Contrave: A mix of bupropion and naltrexone, effective for emotional eating and cravings.
- Newer Injectable Medications:
- Wegovy: A GLP-1 agonist related to Ozempic, which suppresses appetite, enhances energy expenditure, and slows gastric motility.
- Zepbound: A GLP and GIP medication that works similarly to Wegovy, affecting appetite and metabolism.
While injectables have gained significant media attention, Dr. Laster emphasized that the older oral medications can still be effective for many patients.
Seeking Treatment
Dr. Laster advised patients considering weight loss medications to consult a qualified obesity specialist, endocrinologist, or gastroenterologist. These professionals can provide necessary follow-up care, manage dosage adjustments, and ensure patients are supported throughout their treatment.
Cost and Insurance Coverage
The cost of weight loss medications can be a major concern. Dr. Laster noted that while older oral agents typically range from $100 to $200 per month without insurance, newer injectables like Wegovy and Zepbound can cost between $1,500 to $2,000 per month. Some insurance plans may cover these medications, but coverage is not universal. Coupons and alternative dosing options are also available to help reduce costs.
Weight Loss Expectations and Lifestyle Changes
Dr. Laster pointed out that not all patients will experience significant weight loss from these medications. Ongoing research aims to identify which patients may benefit most. Lifestyle changes, including diet and exercise, are critical components of any weight loss plan. Dr. Laster emphasizes personalized approaches, such as meal delivery services and practical nutrition education, to help patients make sustainable choices.
Side Effects and Safety
Addressing concerns about side effects, Dr. Laster stressed the importance of obtaining weight loss medications through reputable healthcare providers. Each patient’s health history must be evaluated to avoid complications. By informing patients about potential side effects and encouraging them to monitor their health, providers can help mitigate risks associated with these medications.
Conclusion
As weight loss medications gain popularity, understanding their differences, costs, and the importance of a holistic approach to weight management is crucial. Dr. Laster’s insights serve as a valuable resource for patients seeking guidance on their weight loss journeys.
