What are weight loss medications?
These medicines are sometimes called GLP-1s, GLP-1 receptor agonists, or incretin therapies. GLP-1 receptor agonists are a class of prescription only medication, originally developed for type 2 diabetes, now also prescribed for weight management in some patients. Access to these medications in the UK is via prescription only, through a GP, specialist weight management service, or registered pharmacy.
How they work
Weight loss medications help some people feel fuller for longer. They can reduce appetite and slow the movement of food through the stomach.
For that reason, they may make it easier to eat less and manage weight, however, they are most effective when paired with everyday habits that support long-term health.
What to focus on
If you are taking weight loss medication, it is still important to eat regularly and choose foods that support your body. The BDA (British Dietetic Association) recommends including protein, fibre rich carbohydrates, fruit and vegetables, and plenty of fluid each day.
It also helps to keep active in ways that feel realistic and sustainable. Even small amounts of movement, along with strength based exercise, can help preserve muscle and support your overall health.
Common side effects
Some people experience side effects, especially when starting treatment or increasing the dose. These can include nausea, constipation, diarrhoea, burping, or other digestive symptoms.
Many of these effects are mild to moderate and improve over time. If symptoms are severe, persistent, or make it hard to eat or drink properly, it is important to speak to a GP, prescriber, pharmacist, or healthcare team.
Who should be careful
These medicines are not suitable for everyone. The BDA advises extra caution if you are pregnant, breastfeeding, planning surgery, taking other medicines, or have a history of disordered eating.
If you take other medication, including treatment for type 2 diabetes or mental health, you should get individual advice before starting. A healthcare professional can check that the treatment is safe and appropriate for you.
