Questions to Ask Before Starting a Medical Weight-Loss Programme

Medical weight-loss services have multiplied quickly, and from the outside they look similar: a questionnaire, a subscription, a prescription in the post. Underneath, they differ enormously — some provide genuine clinical oversight, others are essentially order fulfilment with a clinician's signature attached.

The distinction matters because these are real medications with real contraindications. Here are the questions that tell the two apart.

1. Who is the prescriber, and will I speak to them?

A genuine programme should involve a licensed clinician who reviews your history, current medications and relevant laboratory work before prescribing, and who remains reachable afterwards. Ask for the prescriber's name, credential and state licensure, and confirm it — these are publicly verifiable.

Warning signs: a prescription issued from a questionnaire alone with no clinician interaction, no named prescriber, or no route to contact anyone clinical about side effects. If the only support channel is a general customer service inbox, you are buying fulfilment.

2. What laboratory work do you require, and what do you do with it?

Baseline bloods are how a clinician identifies things that change the plan — thyroid dysfunction, diabetes, kidney or liver issues, lipid abnormalities. A programme that requires none has decided not to look.

Ask also whether they repeat testing during treatment, and who reviews the results. "We'll order labs" and "a clinician reviews your labs and adjusts accordingly" are different services.

3. Am I actually eligible, and will you tell me if I am not?

Prescribing for weight management generally follows criteria based on body mass index — commonly a threshold around 30, or around 27 alongside a weight-related condition such as type 2 diabetes, hypertension, sleep apnoea or dyslipidaemia.

A reputable service declines people outside its scope. It should also screen for eating disorders, pregnancy or planned pregnancy, and personal or family history of medullary thyroid carcinoma or MEN 2, which are contraindications for the incretin class. A programme that appears to approve everyone is not screening.

4. Is the medication FDA-approved or compounded?

This is the most important consumer-protection question in the category, and the answer is often buried.

Shortages of branded incretin medicines led to widespread sale of compounded versions. These are not FDA-approved products and have not been through the same review for safety, efficacy, quality or consistency. Regulators have issued warnings about dosing errors, unapproved salt forms of the active ingredient, and sellers operating outside legitimate pharmacy oversight — including material marketed as "research use only".

If a programme offers a compounded product, ask: which pharmacy compounds it, and is it a licensed and inspected facility? What exactly is the active ingredient and its chemical form? Who measures the dose, and how? What happens if I have an adverse reaction? A price far below the market for the branded equivalent is a reason to ask more questions, not fewer.

5. What is the total monthly cost, including everything?

Ask for one number covering medication, consultations, laboratory work and shipping — and then ask what it becomes after any introductory period. Advertised pricing in this category frequently reflects a first-month rate.

On insurance: coverage for weight-management medication is inconsistent. Many plans exclude it outright, some cover it only with documented prior authorisation or evidence of prior attempts, and some cover it for diabetes but not for weight alone. Employer plans have been narrowing coverage as costs rise. Check your own formulary and prior-authorisation requirements rather than relying on a programme's claim that it "works with insurance". Manufacturer savings programmes exist but usually require commercial insurance and exclude government plans.

6. What is the plan when I stop?

This is the question people ask last and should ask first.

Clinical trial evidence indicates that much of the weight lost with incretin medication is regained after discontinuation. That reframes these drugs as treatment for a chronic condition rather than a course you complete — with real financial implications, because the relevant question is not whether you can afford three months but whether the arrangement is sustainable.

Ask what the programme's approach is to maintenance, tapering, or transition if you stop. A service that will not discuss this candidly is not planning for your actual situation.

7. What non-medication support is included?

The evidence is consistent that medication works best alongside dietary and activity change, and that structured behavioural support improves outcomes. Ask what is actually included — dietitian access, behavioural coaching, structured programme content — and whether it costs extra.

This is also a reasonable proxy for how the business thinks. A programme built only around dispensing has a different theory of your problem than one that also addresses eating, activity, sleep and the reasons weight came on.

What to expect regarding side effects

For general awareness rather than as advice: gastrointestinal effects are common with the incretin class — nausea, vomiting, constipation, diarrhoea — and typically most pronounced when starting or increasing a dose. Prescribing information also discusses pancreatitis and gallbladder disease, and carries a boxed warning regarding thyroid C-cell tumours observed in rodent studies. There are important precautions around pregnancy, other diabetes medications, and planned surgery or anaesthesia.

Which medication is appropriate, at what dose, and whether any is appropriate at all is a clinical decision specific to you. The point of asking the questions above is to make sure someone qualified is actually making it.

Red flags, condensed

• A prescription with no clinician interaction, no history taken and no laboratory work.
• No named, verifiable prescriber, or no way to reach anyone clinical about side effects.
• Promised amounts or rates of weight loss, or before-and-after imagery presented as typical.
• Pressure to buy long prepaid packages, or subscriptions that are difficult to cancel.
• Vagueness about the source, pharmacy or composition of a compounded medication.
• No discussion of what happens when treatment ends.
