Is GLP-1 Safe For Me?
GLP-1 medications like tirzepatide and semaglutide can be very effective, but they aren’t right for everyone. They may not be recommended if you have a personal or family history of certain thyroid cancers, severe gastrointestinal issues, or if you’re pregnant or breastfeeding.
The good news is you don’t have to figure this out alone, during your consultation, Sarah Duffy, FNP will review your health history and labs to make sure GLP-1 therapy is safe and the right fit for you.
Common Myths About GLP-1 Therapy Debunked
When it comes to GLP-1s, misinformation and myths can create unnecessary fear and confusion. At CosmeticsMD, we believe in providing our patients with accurate information to help them make informed decisions about their treatments. Here, we debunk some of the most common myths related to GLP-1s.
While GLP-1 medications like Semaglutide and Tirzepatide are commonly used to manage Type 2 diabetes, they are also approved for weight loss in individuals without diabetes. These medications help regulate appetite, promote satiety, and support healthy weight loss in a wide range of patients.
Myth 1: GLP-1 Therapy is Only for People with Diabetes
GLP-1 therapies are FDA-approved and have been extensively studied for both safety and efficacy. While there can be side effects, they are typically mild and manageable. At CosmeticsMD, our board-certified physicians closely monitor your progress to ensure your safety and adjust your treatment as necessary.
Myth 2: GLP-1 Therapy is Unsafe
Some people may experience mild gastrointestinal side effects such as nausea, diarrhea, or constipation, especially when starting treatment. These symptoms often improve over time as your body adjusts to the medication. Our medical team at CosmeticsMD provides guidance on managing any side effects to ensure a comfortable treatment experience.
Myth 3: GLP-1 Medications Cause Severe Gastrointestinal Issues
GLP-1 medications are designed to support long-term weight management. Studies show that patients who continue with their prescribed GLP-1 therapy and make lifestyle changes can maintain significant weight loss over time. Our membership plans at CosmeticsMD include ongoing support to help you sustain your results.
Myth 4: You Can't Maintain Weight Loss with GLP-1 Therapy
GLP-1 therapy is not a magic bullet; it works best when combined with healthy lifestyle changes such as diet and exercise. At CosmeticsMD, we provide comprehensive support to help you achieve and maintain your weight loss goals.
Myth 5: GLP-1 Therapy is a Quick Fix
While the cost of GLP-1 medications can be a concern, CosmeticsMD offers membership plans that provide cost-effective access to these treatments. Our memberships also include discounts on cosmetic treatments to address skin laxity, wrinkles, and lower muscle mass, as well as B12 shots, ensuring you get the best value for your investment in your health.
Myth 6: GLP-1 Therapy is Too Expensive
GLP-1 therapy is not suitable for everyone. Individuals with a personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome type 2, severe gastrointestinal disease, or pancreatitis may not be candidates for this treatment. Our providers at CosmeticsMD will review your medical history to determine if GLP-1 therapy is right for you.
Myth 7: Anyone Can Use GLP-1 Therapy
