Asking your doctor about GLP-1 therapy feels daunting if you don't know what to say — but the conversation is more structured than most patients expect. This guide gives you the exact questions to ask, the labs to request, and the signs that your doctor is (or isn't) prepared to manage a GLP-1 protocol properly.
- You need a BMI of 30+, or 27+ with a comorbidity, to qualify for GLP-1 therapy.
- A doctor should confirm baseline labs (fasting glucose or HbA1c, CMP, lipid panel) before prescribing.
- Ask for the full dose escalation schedule up front, not just the starting dose.
- Monthly follow-up during titration with lab rechecks every 8-12 weeks is the standard of proper management.
- A prescription with no follow-up plan means you're being prescribed at, not managed.
- If your primary care doctor won't manage GLP-1 titration, a DPC membership or telehealth weight loss clinic can fill that gap.
TL;DR
The conversation about starting GLP-1 therapy should focus on three things: whether you meet the clinical criteria (BMI 30+, or 27+ with a comorbidity), what labs your doctor plans to order before prescribing, and what the follow-up cadence looks like. A doctor who prescribes without labs or a follow-up plan is cutting corners. GoodLife Health's direct primary care membership ($179/month) builds this conversation into a structured intake visit with a licensed clinician. Verdict: the right doctor welcomes this conversation — if yours doesn't, that's the answer about whether they're the right clinician for GLP-1 management.
Why this matters
GLP-1 medications (semaglutide, tirzepatide) are the most effective weight loss pharmacotherapy available in 2026, but they require ongoing clinical management — dose titration, side-effect monitoring, and lab rechecks. A doctor who writes the prescription and says "see me in six months" isn't managing the protocol; they're starting it and abandoning it.
The STEP trials (semaglutide) and SURMOUNT trials (tirzepatide) both demonstrated that weight loss continues for 68-72 weeks with ongoing dose escalation. A single visit at the start doesn't cover that timeline — and most primary care doctors weren't trained in GLP-1 dose management during residency, because these drugs are too new.
What you'll need
- Your current BMI calculation (weight in kg ÷ height in meters²)
- A list of current medications, especially anything affecting glucose or thyroid
- Your most recent lab results if you have them from the past 90 days
- A symptom log: weight history, energy, appetite, sleep — anything relevant to the conversation
- A list of questions (see below) — written down, not in your head
- Your insurance information, or a budget if you're self-pay
The steps
1. Calculate your BMI and confirm eligibility before the visit
GLP-1 medications for weight loss require a BMI of 30 or higher, or 27+ with a weight-related comorbidity (hypertension, prediabetes, dyslipidemia, sleep apnea, PCOS). Walk into the visit knowing your number — a doctor who has to calculate it during a 15-minute slot may not have time to discuss the full protocol. Common mistake: guessing your BMI instead of calculating it — "I think I'm around 30" isn't precise enough.
2. Bring up GLP-1 therapy directly, not as a hint
Doctors respond better to direct requests than subtle hints. Say: "I've been reading about GLP-1 medications for weight loss, and I'd like to discuss whether semaglutide or tirzepatide is appropriate for me." This frames it as a clinical discussion, not a demand. Common mistake: waiting for the doctor to suggest it — many won't, because they don't know your interest or don't prescribe GLP-1s routinely.
3. Ask about the lab panel they order before prescribing
A doctor who prescribes a GLP-1 without baseline labs is skipping a step. Ask specifically: "What labs do you order before starting a GLP-1?" The answer should include at minimum a fasting glucose or HbA1c, a comprehensive metabolic panel, and a lipid panel. Some clinicians also check thyroid function. Common mistake: not asking about labs because you assume they'll be ordered — some providers skip them, especially in telehealth settings.
4. Ask about the dosing and titration schedule
Semaglutide starts at 0.25mg weekly and escalates every 4 weeks; tirzepatide starts at 2.5mg and follows a similar 4-week step-up. Your doctor should be able to give you the full escalation schedule at the first visit, not just the starting dose. Ask: "What's the full dose escalation schedule, and how do you decide when to hold vs. step up?" Common mistake: leaving the visit knowing only the starting dose and having no idea when or how it changes.
5. Ask about the follow-up cadence
This is the question that separates a managing clinician from a prescribing one. Ask: "How often do I see you after starting, and what do you check at each visit?" The answer should include monthly visits during titration and lab rechecks at 8-12 week intervals. A doctor who says "follow up in three months" is not managing a titration protocol. Common mistake: accepting "call if you have problems" as a follow-up plan — that's reactive, not proactive management.
6. Ask about side-effect management before you experience side effects
Nausea, constipation, and fatigue are common in the first 4-8 weeks. Ask your doctor: "What side effects should I expect, and what's your plan for managing them?" A prepared clinician will discuss dose holds, slower titration, and symptomatic management. An unprepared one will say "call me if it happens." Common mistake: not discussing side effects until you're already nauseated and frustrated.
7. Ask about the maintenance plan before starting
GLP-1 therapy isn't a 12-week course — it's a multi-month to multi-year protocol. Ask: "What happens when I reach my target weight? Do I stay on the medication, taper off, or switch to a maintenance dose?" A doctor who hasn't thought about this before you reach your goal isn't managing the full arc. Common mistake: treating the starting dose as the whole plan and discovering at month 6 that nobody discussed maintenance.
8. If your doctor doesn't prescribe GLP-1s or won't manage them, ask for a referral or consider a DPC membership
Not all primary care doctors prescribe GLP-1 medications, and many who do won't manage ongoing titration. That's not a failure on your part — it's a scope-of-practice question. Ask for a referral to a weight management specialist, or consider a direct primary care membership that includes GLP-1 management. Common mistake: giving up on GLP-1 therapy because your primary care doctor doesn't prescribe — there are clinicians who do.
Questions to Ask Before Starting GLP-1 Therapy
What a good answer includes
| Question | A prepared clinician's answer |
|---|---|
| "What labs do you order before starting a GLP-1?" | Fasting glucose or HbA1c, CMP, lipid panel — sometimes thyroid function |
| "What's the full dose escalation schedule?" | Full titration timeline, not just the starting dose |
| "How often do I see you after starting?" | Monthly visits during titration, lab rechecks at 8-12 week intervals |
| "What side effects should I expect, and how do we manage them?" | Discussion of dose holds, slower titration, symptomatic management |
| "What happens when I reach my target weight?" | A stated plan: stay on medication, taper, or switch to maintenance dose |
A doctor who says "follow up in three months" is not managing a titration protocol.
Troubleshooting
Your doctor says GLP-1s are "dangerous" or "a fad." Ask for specifics: what risks concern them? GLP-1s have real risks (pancreatitis, GI side effects, muscle loss), but the STEP and SURMONT trials demonstrated a favorable benefit-risk profile for patients who meet criteria. A doctor who dismisses them without discussing the evidence may not be up to date.
Your doctor prescribes but doesn't follow up. This is the most common pattern in 2026 — a prescription with no titration plan. Ask for a follow-up visit at 4 weeks specifically to discuss dose escalation and side effects. If that's not available, consider switching to a telehealth weight loss clinic that structures follow-up into the model.
Your insurance denied coverage. Ask your doctor's team to submit a prior authorization with documentation of BMI and comorbidities. If denied again, discuss self-pay options or compounded alternatives with your clinician.
Your doctor says you don't qualify. Confirm the criteria: BMI 30+ or 27+ with a comorbidity. If you're at BMI 28 with prediabetes, you qualify. If your doctor is using a different threshold, ask them to explain the reasoning.
Your doctor wants you to "try diet and exercise first." If you have a BMI 30+ and have attempted lifestyle changes without sustained weight loss, GLP-1 therapy is appropriate — it's not a last resort. The STEP trials included patients who had prior lifestyle attempts.

FAQ
How do I ask my doctor for a GLP-1 prescription? Directly: state your interest, confirm your BMI meets criteria, and ask whether semaglutide or tirzepatide is appropriate for your clinical situation. Bring your weight history and a list of prior weight loss attempts to support the conversation.
What if my doctor won't prescribe GLP-1 medications? Ask for a referral to a weight management specialist or consider a direct primary care membership that includes GLP-1 therapy. Not all primary care doctors prescribe these medications — it's a scope-of-practice question, not a reflection on you.
What BMI do you need for a GLP-1 prescription? A BMI of 30 or higher, or 27+ with a weight-related comorbidity such as hypertension, prediabetes, dyslipidemia, or sleep apnea. Your doctor confirms this at the visit.
What questions should I ask before starting GLP-1 therapy? Ask about: the lab panel they order before prescribing, the full dose escalation schedule, the follow-up cadence, the side-effect management plan, and the maintenance plan after you reach your target weight.
How often should I see my doctor after starting a GLP-1? Monthly during the dose escalation phase (first 12-16 weeks), then quarterly once on a stable maintenance dose. Lab rechecks at 8-12 week intervals minimum.
Does insurance cover GLP-1 medications? Many plans cover brand-name Wegovy or Zepbound with prior authorization, especially if you have a qualifying BMI and comorbidity. Compounded versions are typically not covered. Your doctor's team should help with the prior authorization process.
What if my doctor says I should try diet and exercise first? If you meet BMI criteria and have attempted lifestyle changes without sustained weight loss, GLP-1 therapy is clinically appropriate — the clinical trials included patients with prior lifestyle attempts. Ask your doctor to explain their reasoning if they're declining.
One last thing
The single question that reveals whether your doctor will manage your GLP-1 protocol or just prescribe it: "When's the next visit, and what will you check?" If the answer is "call me if you have problems," you're being prescribed at, not managed. A good clinician sets the follow-up before you leave the first visit.
