Most people have a fair idea of what they want from a weight management clinic. Far fewer know what actually happens once they start, and that gap is enough to stop people beginning at all.
So here is the whole thing, start to finish. What you will be asked, who reads it, how long each part takes, and what you are told at the end — including when the answer is no.
What happens in your first weight management consultation?
You complete a clinical questionnaire covering your height and weight, medical history, current medicines and previous attempts at weight management. A UK-registered clinician reviews it, may come back with follow-up questions, and then tells you whether treatment is appropriate. It is done in writing rather than on a call.
Most people are through the questionnaire in ten to fifteen minutes.
Step one: the questionnaire
Longer than you might expect, and that is deliberate. It covers your measurements, your family background — which changes the thresholds that apply — your medical history, everything you currently take, and what you have already tried.
Answer it honestly rather than strategically. A clinician can only assess what they are told, and an assessment built on a tidier version of your history is not an assessment.
Step two: identity and measurement checks
You will be asked to verify your identity and to confirm your measurements. This is a legal and clinical requirement rather than an administrative habit. In February 2025 the General Pharmaceutical Council updated its guidance so that online services must verify what a patient reports rather than take it at face value, specifically because of concerns about weight management medicines.
We use a guided body scan on your phone rather than asking for a photograph. It takes a couple of minutes and nobody is watching while you do it.
This is also the stage where most people stall. If you get stuck, it is worth asking for help rather than leaving it — a clinician will get in touch either way.
Step three: clinical review
At VSC, a UK-registered clinician reads it. Not an algorithm, not a checkbox. They are weighing your measurements against the correct thresholds, your history, your current medicines and what you are trying to achieve.
Step four: questions, if there are any
Often a clinician needs something clarified before deciding. If that happens you will be asked directly. It is not a delay tactic — it usually means they are taking something in your history seriously.
If your verification did not come through cleanly, this is when a clinician will message you and arrange a short call, usually around ten minutes, to go through your assessment together.
Step five: the outcome
You are told whether treatment is appropriate and why. If it is, you will know what happens next and what monitoring looks like. If it is not, you will be told the reason in plain terms, and where something else would help more, what that is.
Any slimming clinic worth using should be willing to tell you no. Several things can make treatment unsuitable, and a good assessment is built to find them.
How long the whole thing takes
The questionnaire is five to ten minutes. Verification adds a couple of minutes. Clinical review is usually the same day or next working day, and longer only if follow-up questions are needed and you are slow to reply.
What it is not
It is not a form that automatically approves you. It is not a sales call. And it is not a commitment — you can stop at any point before treatment begins.
Frequently asked questions
How long does a weight management consultation take? The questionnaire takes around five to ten minutes. Clinical review is usually same or next working day.
Do I need to speak to someone on the phone? No. The assessment is completed in writing and reviewed by a clinician. You can message the clinical team at any point if you would rather discuss something, and a clinician will call you if your verification needs going through.
Who reviews my consultation? At the virtual slimming clinic a UK-registered clinician reviews your assessment. Not an automated system.
Do I need a GP referral? No. You can be assessed directly. With your consent your GP can be kept informed, which is part of safe care.
What if I don't know an answer? Say so rather than guessing. A clinician would far rather have an honest "I'm not sure" than a confident wrong answer.
Can I stop partway through? Yes, at any point before treatment begins. Nothing is charged until treatment is prescribed.
Why do I have to verify my measurements? Because UK guidance requires it. Services must verify what you report rather than accept it at face value, and there must be two-way communication with a prescriber before a decision is made.
