What is Wegovy and how does it work?
Wegovy is the brand name for semaglutide, a medication designed to help regulate appetite and food intake. It works by mimicking a naturally occurring hormone involved in hunger signalling and blood sugar management known as GLP-1, helping patients feel fuller for longer and reducing overall calorie intake.
For many patients, Wegovy can be an effective treatment option when used alongside dietary changes, increased physical activity and ongoing clinical support. It is typically prescribed as part of a wider weight management plan rather than used as a standalone solution.

Who can get Wegovy in the UK?
Wegovy is a prescription-only medicine in the UK and is only available following a clinical assessment.
Eligibility will usually depend on factors such as:

A regulated provider will usually ask you to complete a medical questionnaire before deciding whether Wegovy is appropriate.
Wegovy cost UK
The cost of Wegovy in the UK can vary depending on the dosage prescribed, the stage of treatment and the provider you use.
In many cases, the monthly price may include:
- The medication
- Clinician reviews
- Prescription approval, where appropriate
- Delivery
- Access to patient guidance or support
When comparing Wegovy providers, it is important to look beyond the headline monthly cost. Lower prices do not always include the same level of support, and patients should consider the overall value of the service as well as the medication itself.
Wegovy dosage
Wegovy is usually started at a lower dose and gradually increased over time, depending on how well the medication is tolerated and the treatment plan agreed with your clinician.
This gradual increase helps reduce the chance of side effects and allows your body to adjust. Patients should always follow the dosage instructions provided by their prescriber and should not change dose levels without clinical guidance.
