Wegovy vs Ozempic: what are they used for?
Wegovy is licensed for weight management, while Ozempic is licensed for type 2 diabetes. Both medications can support metabolic health, but their approved uses in the UK are different and prescribing depends on your individual health needs.
Wegovy for weight loss
Wegovy is approved for adults living with obesity or those who are overweight and have weight-related health conditions. It can usually be prescribed if your BMI is 30 kg/m² or above, or 27 kg/m² or above if you also have weight-related conditions, following a clinical assessment.
Prescribing criteria are different for NHS and private treatment. NHS access is usually stricter and often limited to people with a higher BMI or additional health conditions and may require referral to a specialist service.
Wegovy works best when combined with healthy lifestyle changes. This includes regular movement, eating more balanced meals, reducing highly processed foods, improving sleep, and managing stress. The medication supports these changes, but long-term success depends on the habits you build alongside it.

Wegovy for heart health
Wegovy is the first weight loss injection to also be approved to reduce the risk of serious heart-related events in certain patients. It has been shown to lower the risk of major cardiovascular events, like heart attack and stroke, by 20% in adults that are overweight or obese and have existing heart disease.
As with weight management, Wegovy for heart health is prescribed under specific criteria and should be used alongside healthy lifestyle changes. Diet, physical activity, and long-term habit changes remain essential for protecting your heart.

Ozempic for type 2 diabetes
Ozempic is licensed to improve blood sugar control in adults with type 2 diabetes. It may also reduce cardiovascular risk in certain people with diabetes.
It may be available:
- on the NHS for eligible patients with type 2 diabetes
- privately with a prescription
Ozempic is not licensed in the UK solely for weight loss to protect supply and prevent shortages. Patients seeking weight loss treatment are directed to use Wegovy or other licensed options.
How do Wegovy and Ozempic work?
Both treatments contain semaglutide, a GLP-1 receptor agonist that mimics a natural hormone involved in appetite and blood sugar regulation.
GLP-1 medicines:
- slow stomach emptying
- increase feelings of fullness
- stimulate insulin release when blood sugar is high
- reduce appetite signals in the brain
For weight loss, this leads to eating less naturally, feeling full sooner, and reducing overall calorie intake without constant hunger. Over time, this can support steady and clinically meaningful weight reduction when combined with lifestyle changes.
For type 2 diabetes, these effects help lower blood sugar levels by improving insulin response and reducing glucose spikes after meals. This supports better long-term blood sugar control and may reduce the risk of diabetes-related complications.
How does Wegovy help with weight loss?
Wegovy supports weight loss by reducing appetite and helping you feel full sooner.
It works best when paired with:
- Calorie awareness: Consuming less high fat & high sugar foods.
- Balanced nutrition: Incorporating more nutritionally dense, high fibre and less processed foods into your diet.
- Regular movement: To strengthen muscle mass, improve heart health and support weight loss.
When combined with the introduction of healthy habits, Wegovy is an effective and sustainable weight management treatment for individuals.
“Wegovy and Ozempic contain the same active ingredient, semaglutide, so they work in the same way in the body. However, in the UK they are licensed for different conditions and prescribed with different treatment goals.
“Wegovy follows a dosing schedule designed specifically to support weight management, with gradual increases to a higher maximum dose. Ozempic is licensed for type 2 diabetes and is usually prescribed at lower doses to help control blood sugar levels.
“While the medication itself is the same, the dose, clinical pathway and purpose of treatment are different. Choosing the right option depends on a person’s health needs and a proper clinical assessment.”
