How to Talk to Your Doctor About Starting GLP-1

GLP-1 Companion · 8 min read

GLP-1 receptor agonists represent the most significant advance in obesity medicine in decades, yet a large proportion of eligible patients never receive a prescription. Research published in the journal Obesity consistently shows that weight bias in medical settings remains a barrier — patients are often told to "eat less and move more" rather than being offered evidence-based pharmacotherapy. Knowing how to advocate for yourself in a medical appointment makes a real difference.

Knowing Whether You Are Likely Eligible

FDA-approved GLP-1 medications for chronic weight management have well-defined eligibility criteria. Understanding these criteria before your appointment helps you frame the conversation with specificity and confidence.

• BMI of 30 or greater (obesity), with or without weight-related comorbidities
• BMI of 27 or greater (overweight) with at least one weight-related comorbidity such as type 2 diabetes, hypertension, high cholesterol, obstructive sleep apnea, or cardiovascular disease
• A documented history of attempting lifestyle modifications (diet and exercise) with insufficient results
• Absence of contraindications such as a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2

How to Bring It Up If Your Doctor Has Not

Many primary care physicians are aware of GLP-1 medications but may not proactively offer them due to time constraints, cost concerns on behalf of the patient, or uncertainty about the patient's interest. You can open the conversation directly without it feeling awkward. A straightforward approach works well: "I've been reading about GLP-1 medications for weight management and I'd like to talk about whether I might be a candidate."

Framing the conversation around health outcomes rather than aesthetics tends to be more effective in clinical settings. Focus on concrete health goals: reducing your blood pressure, improving your A1C, reducing joint pain, improving sleep apnea, or reducing your cardiovascular risk. These are the outcomes that GLP-1 trials have demonstrated and that your physician is trained to think about.

Documentation to Bring to the Appointment

Arriving prepared demonstrates that you have thought seriously about this decision and makes it easier for your physician to build the clinical case required for insurance authorization.

• Weight history: any records showing your weight over the past 1 to 5 years, or a written summary of weight trends
• Diet and exercise attempts: a brief written summary of structured attempts you have made — specific programs, calorie restriction periods, gym membership, working with a dietitian
• List of current comorbidities and their status (controlled or uncontrolled hypertension, diabetes, sleep apnea, etc.)
• Current medication list: some insurers require documentation that you are not already on conflicting medications
• Recent lab results if available: fasting glucose, A1C, lipid panel, thyroid function

Framing the Conversation Around Health, Not Appearance

While your reasons for wanting to lose weight are entirely your own, physicians are more likely to engage substantively with the conversation when it centers on metabolic health. The clinical literature supporting GLP-1 therapy is built around outcomes like cardiovascular event reduction (the SURMOUNT and SELECT trials), glycemic control, and reduction of obesity-related disease burden. Mentioning that you want to reduce your risk of cardiovascular disease or improve your blood sugar control situates the conversation within the evidence base your physician knows.

Dealing With a Hesitant Doctor

Some physicians are hesitant to prescribe GLP-1 medications due to concerns about cost, the supply constraints that affected these drugs from 2022 to 2024, unfamiliarity with the newer agents, or a general preference for lifestyle intervention first. If your doctor is hesitant, ask specific questions: "What would need to be true for you to feel comfortable prescribing this?" or "Is there additional documentation that would help?" If they cite cost, ask whether prior authorization through your insurer is something the practice can initiate.

If a physician dismisses your interest without substantive engagement, it is appropriate to seek a second opinion or a referral. This is not confrontational — it is standard practice in any specialty of medicine.

Getting a Referral to an Obesity Medicine Specialist

Board-certified obesity medicine physicians have specialized training in treating obesity as a chronic disease and are generally more comfortable prescribing and managing GLP-1 therapy. They are also more likely to provide the comprehensive support — dietary counseling, behavioral health integration, dose management — that improves long-term outcomes. If your primary care physician is unwilling or uncomfortable prescribing GLP-1 therapy, ask for a referral to an obesity medicine specialist. The Obesity Medicine Association and the American Board of Obesity Medicine both maintain provider directories.

Online vs. In-Person Prescribing

Since 2020, telehealth prescribing of GLP-1 medications has expanded significantly. Platforms specializing in metabolic health can prescribe FDA-approved semaglutide and tirzepatide after an online visit, often with faster appointment availability than in-person clinics. However, quality of care varies between telehealth providers. Look for platforms staffed by licensed physicians or nurse practitioners with obesity medicine training, that require a full health history and lab review before prescribing, and that include follow-up care and dose management — not just a prescription and a phone number.

Compounded semaglutide and tirzepatide were widely available via telehealth during the shortage period of 2022 to 2024, but the FDA has flagged safety concerns with compounded versions and the branded shortages have largely resolved as of 2025. Stick to FDA-approved, brand-name formulations when possible.

After the Appointment: Next Steps

If your physician agrees to prescribe a GLP-1 medication, the process typically involves a prior authorization submission to your insurer (which your doctor's office handles), followed by pharmacy dispensing once approved. This can take anywhere from a few days to several weeks. In the meantime, ask your physician about baseline labs they would like to run, discuss how often you will check in during dose escalation, and confirm the plan for what to do if side effects are significant.

You know your body and your health history better than anyone. Going into a medical appointment informed, prepared, and clear about your goals puts you in the best position to receive the care you are seeking.
