Quick Answer: Losing even five to ten percent of body weight can produce significant improvements in blood glucose control, blood pressure, and cholesterol for people with type 2 diabetes. Pharmacy-led weight management services can provide evidence-based support, including access to prescription weight loss medicines that are also licensed or used in type 2 diabetes, such as Mounjaro (tirzepatide) and Saxenda (liraglutide), subject to clinical assessment.
Why Is Weight Management So Important in Type 2 Diabetes?
Type 2 diabetes is strongly associated with excess body weight, particularly abdominal (central) obesity. In many cases, excess weight drives the insulin resistance that underlies the condition. Significant weight loss can result in:
- Meaningful improvement in HbA1c (blood glucose control)
- Reduction in blood pressure
- Improvement in cholesterol and triglyceride levels
- Reduction in cardiovascular risk
- In some people, type 2 diabetes remission, particularly where significant weight loss is achieved early in the course of the disease
The landmark DiRECT trial, led by researchers at Newcastle and Glasgow universities, demonstrated that up to 46 percent of participants with type 2 diabetes achieved remission after one year on a structured low-calorie programme producing an average weight loss of approximately 10 kg.
What Weight Loss Medicines Are Available for People With Type 2 Diabetes?
Mounjaro (Tirzepatide)
Mounjaro is licensed in the UK both for the treatment of type 2 diabetes and for weight management (in those with BMI 30 or above, or 27 or above with comorbidity). It is a once-weekly injection that acts on both the GLP-1 and GIP receptors, producing significant reductions in blood glucose and body weight simultaneously. For people with type 2 diabetes already taking certain other diabetes medications, careful dose adjustment and monitoring are required to avoid hypoglycaemia.
Saxenda (Liraglutide 3 mg)
Saxenda (liraglutide 3 mg) is licensed for weight management and is distinct from Victoza (liraglutide 1.2 and 1.8 mg), which is licensed for type 2 diabetes. It can produce meaningful weight loss and blood glucose improvements in people with type 2 diabetes or pre-diabetes, though it is used specifically at the 3 mg weight management dose.
Orlistat
Orlistat is licensed for use in people with type 2 diabetes (with BMI of 28 or above) and can produce modest weight loss alongside dietary changes. It does not affect blood glucose directly but weight loss can improve glucose control. It is important to monitor blood glucose levels when starting orlistat, as improved dietary adherence and weight loss can reduce the dose of diabetes medicines required.
Can Weight Loss Lead to Diabetes Remission?
Remission of type 2 diabetes, defined as achieving normal blood glucose levels without diabetes medication, is achievable for some people with a sustained weight loss of 10 to 15 kg or more, particularly in those diagnosed within the last six years. It is important to understand that remission is not guaranteed and depends on multiple factors including duration of diabetes, current HbA1c, and individual response.
Even where full remission is not achieved, significant weight loss consistently reduces the medication required to manage blood glucose and reduces the risk of long-term diabetes complications including retinopathy, nephropathy, and neuropathy.
Important Considerations When Starting Weight Loss Treatment With Diabetes
People with type 2 diabetes starting weight management programmes and medicines require specific clinical oversight:
- Blood glucose monitoring: Weight loss may cause blood glucose to fall, potentially requiring reduction in doses of sulphonylureas (e.g. gliclazide) or insulin to avoid hypoglycaemia
- Blood pressure monitoring: As weight falls, antihypertensive medication doses may need adjustment
- Kidney function: Some weight loss medicines require dose adjustment in renal impairment
- Medication review: A formal medication review is advisable as weight is lost
At Newdays Pharmacy, our pharmacist-prescribers are trained to manage these considerations and will liaise with your GP where appropriate as part of shared care.

Frequently Asked Questions
For some people, particularly those diagnosed recently and who achieve significant weight loss (10 kg or more), diabetes remission is possible. This means blood glucose returns to normal levels without medication. However, remission is not guaranteed for everyone, and ongoing lifestyle management is needed to sustain it. Your pharmacist and GP will be able to discuss whether remission is a realistic goal for you.
People taking insulin alongside a GLP-1 medicine such as Wegovy, Saxenda, or Mounjaro require careful monitoring and likely insulin dose reduction to avoid hypoglycaemia. This requires close clinical supervision. Speak to your diabetologist or pharmacist before making any changes to your insulin dose.
