Guide to GLP-1 Medicines

GLP-1 medicines work by mimicking the action of the natural hormone GLP-1, which helps to regulate blood sugar levels and appetite. They have three primary effects: they help to lower blood sugar, reduce hunger, and prolong feelings of fullness after eating. Some GLP-1 medicines also incorporate a second hormone, GIP, to enhance their effects.

The main GLP-1 medicines available in the UK include Ozempic and Wegovy, both of which contain the active ingredient semaglutide. Ozempic is licensed for type 2 diabetes, while Wegovy is specifically approved for weight management. It's important to note that although they contain the same active ingredient, they are not interchangeable due to their different licenses.

GLP-1 medicines are often used in conjunction with other diabetes treatments, such as metformin or insulin. They work on different pathways, allowing for a more comprehensive approach to managing blood sugar levels. Prescribers carefully consider combinations to avoid potential side effects, such as low blood sugar.

When beginning GLP-1 treatment, patients typically start with a low dose that gradually increases. This helps to minimise side effects, which are often mild and related to digestion. Patients can expect changes in appetite and food preferences over time as their bodies adjust to the medication.

GLP-1 medicines can significantly aid in weight management by reducing appetite and promoting a feeling of fullness. They are not a quick fix but rather a part of a long-term strategy that includes dietary changes and physical activity.

For individuals with type 2 diabetes, monitoring HbA1c levels is crucial. GLP-1 medicines can help lower these levels, indicating better blood sugar control over time. Regular check-ups with healthcare providers are essential to assess the effectiveness of the treatment.
