How an online weight-loss consultation works
The pathway is shorter than most people expect, but every stage exists for a reason. From questionnaire to decision usually takes a day or two, and sometimes less.
- You complete a health questionnaire. Your height and weight, medical history, current medicines, and questions about your general health. Most providers also ask for photo or ID evidence so the prescriber isn't relying on self-declared numbers alone.
- A registered prescriber reviews it. Depending on the provider this is a doctor, a pharmacist prescriber or a nurse prescriber. Some follow up by message or a short video call before deciding.
- They make a clinical decision. Approve, ask for more information, or decline and point you back to your GP. A decline is the system working, not a fault in it.
- Ongoing check-ins. If treatment starts, a responsible provider reviews your progress before each repeat supply rather than shipping on autopilot.
"Without a GP" doesn't mean "without a clinician"
This is the part the phrase "skip the GP" gets wrong. What you skip is the waiting room, not the assessment. The prescriber at a regulated online provider carries the same legal responsibility for the decision as a GP writing the same prescription, and works to the same prescribing standards set by the GMC and the pharmacy regulator.
An online consultation is a clinical assessment by a registered prescriber, not a way around one. Any site offering prescription-only treatment with no consultation at all is operating outside UK rules — here's how to check a pharmacy is registered before you go further.
The practical difference from a GP appointment is scope. Your GP knows your full record; an online prescriber knows what you tell them plus whatever evidence they ask for. That's why the questionnaire is long, and why honest answers matter more here than anywhere else.
What a good provider checks before prescribing
Providers differ in how thoroughly they assess. These checks are the ones worth comparing on:
- Your BMI, with some form of verification rather than a bare self-declared figure.
- Medical history and every medicine you currently take, so interactions and unsuitable combinations get caught.
- Weight-related conditions, and any history that would make treatment unsuitable.
- A named, registered prescriber you can look up — and a registered pharmacy doing the dispensing.
- A follow-up plan: scheduled reviews, a way to report problems, and a route to stop treatment safely.
A provider that asks you almost nothing has cut the one part of the service that protects you.
Will they tell your GP?
Regulated providers ask during the consultation whether they may share details of your treatment with your GP, and good practice guidance from the GMC encourages that sharing. You can usually decline, and your GP surgery is not told without your consent. Letting them know is worth it, though: your GP record is where drug interactions, blood-test history and future care all connect, and an informed GP can spot problems an online provider can't see.
Is it right for you?
Online assessment suits people who already know weight-loss treatment is a realistic option for them and want a regulated route that fits around work. It suits nobody as a way of getting a "yes" after a GP has said no — a regulated prescriber will reach the same answer, for the same reasons.
Whether a provider will consider you at all mostly comes down to BMI and any weight-related conditions. We've set out who is usually eligible for weight-loss treatment separately, our weight-loss guide covers how to judge a provider once you're looking, and the weight-loss comparison shows what each regulated provider's service includes and charges.
