Do You Need Your GP to Prescribe Weight Loss Injections?

Find out whether you need a GP referral for weight loss injections in the UK. Learn about NHS weight management programmes and private alternatives from iQ Doctor.

Weight loss injections like Wegovy (semaglutide) and Mounjaro (tirzepatide) have become increasingly popular in the UK for supporting safe and sustainable weight loss. However, many people wonder whether they can get these treatments directly or if they first need approval from their GP.

Below, we’ll explain how the NHS weight management referral scheme works, who qualifies, and how you can access effective, clinician-approved treatment privately through iQ Doctor.

Can a GP Prescribe Weight Loss Injections?

Yes — GPs can prescribe weight loss injections, but only under certain conditions. Most people need to be referred to an NHS weight management programme before being considered for medication like Wegovy or Mounjaro. The NHS weight management programme typically involves lifestyle support, including guidance on diet, exercise, and behavioural changes. Only after completing or engaging in such a programme might you be offered a prescription for an approved injection, depending on your BMI and medical history.

How the GP Weight Loss Referral Scheme Works

The GP weight loss referral scheme is designed for people who need extra medical support for managing obesity. Here’s how it usually works:

1. Initial GP Consultation:

   Your GP assesses your weight, BMI, and any related conditions (like type 2 diabetes or high blood pressure).

2. Referral to a Weight Management Programme:

   If eligible, your GP refers you to an NHS weight management programme for 12 weeks or longer. This may include group sessions, diet plans, or physical activity support.

3. At least four of the following five health conditions must be diagnosed and recorded in your medical history:

• Hypertension (high blood pressure requiring medication)
• Obstructive sleep apnoea, confirmed by a sleep clinic
• Type 2 diabetes
• Cardiovascular disease (including heart disease, stroke or vascular disease)
• Hypercholesterolaemia (high cholesterol)
4. Consideration for Medication:

After or during your programme, your GP may prescribe weight loss medication — such as semaglutide (Wegovy) — if you meet clinical criteria.

​​NHS vs Private Access to Weight Loss Injections

NHS Access

The NHS offers weight loss injections primarily to people who:

• Have a BMI of 35 or higher (or 30+ with certain conditions)
• Are enrolled in an approved NHS weight management programme
• Are high risk with additional co-morbidities
• Have not achieved sufficient results through lifestyle changes alone

Access may also vary by region, as some areas have limited supply or different prescribing guidelines.

Private Access

If you don’t qualify through the NHS or prefer a faster route, iQ Doctor provides a UK-certified private alternative.

Through a simple online consultation, a qualified clinician reviews your health details and, if appropriate, issues a prescription for an approved weight loss injection such as:

• Wegovy (semaglutide)
• Mounjaro (tirzepatide)

This allows you to begin treatment safely and conveniently — without waiting for a GP referral.
