Understanding GLP-1 Medicines
An overview of GLP-1 medicines, their uses, and how they work.
The basics
How GLP-1 works
GLP-1 medicines are prescription-only treatments that mimic a natural gut hormone. They are used in the UK for type 2 diabetes and weight management, and they work best alongside healthy lifestyle habits — not as a standalone solution.
They are not quick fixes or fat burners. They are long-term treatments, and a qualified clinician decides whether they suit each person's health and circumstances.

Released after eating
GLP-1 is a hormone the gut releases after a meal, signalling the body to manage blood sugar.

Steadier blood sugar
These medicines enhance that natural process, helping maintain steadier blood sugar levels.

Feeling fuller for longer
They also help reduce hunger, so people can feel fuller for longer alongside lifestyle changes.
GLP-1 medicines are prescription-only treatments that mimic a natural gut hormone called glucagon-like peptide-1. This hormone helps manage blood sugar levels and appetite. In the UK, these medicines are used for type 2 diabetes and weight management, but they are not a standalone solution; they work best alongside healthy lifestyle habits.
GLP-1 is released by the gut after eating, signalling the body to regulate blood sugar and reduce hunger. GLP-1 medicines are designed to enhance this natural process, helping individuals maintain steadier blood sugar levels and feel fuller for longer.
There are many myths surrounding GLP-1 medicines, such as the belief that they are quick fixes or fat burners. In reality, they are long-term treatments that require a commitment to lifestyle changes alongside their use.
In the UK, a qualified clinician determines the suitability of GLP-1 medicines for each individual. This ensures that the treatment aligns with the patient's health needs and circumstances.
