Weight Loss (Video Consult)

Prescription weight loss medications are typically suitable for adults with a BMI of 30 or above, or a BMI of 27 or above with weight-related health conditions such as type 2 diabetes, high blood pressure or high cholesterol. A consultation ensures the medication is safe for you, taking into account any existing medical conditions, current medications and your overall health. Weight loss medications are not suitable during pregnancy or breastfeeding, and certain conditions may rule out specific treatments.

Like all medications, weight loss treatments can cause side effects. The most common side effects of GLP-1 injections such as Mounjaro and Wegovy include nausea, diarrhoea, constipation and reduced appetite, particularly when starting treatment or increasing the dose. These tend to ease as the body adjusts over the first few weeks. Orlistat-based treatments like Xenical may cause digestive side effects related to fat absorption. A prescriber will discuss potential side effects with you during your consultation and advise on the safest option based on your individual health profile.

Once your consultation is complete and your prescription has been approved, your medication is typically dispatched within one to two working days. Delivery times depend on your location, but most UK orders arrive within two to three working days of dispatch. If you need your treatment sooner, express delivery options may be available. We dont ordinarily ship on a Friday due to delivery problems on a the weekend and weight loss medication will need signed for.

Most people notice a reduction in appetite within the first one to two weeks of starting treatment with GLP-1 injections. Visible weight loss typically begins around weeks four to eight. Clinical studies show that patients using Mounjaro or Wegovy often achieve around 5% body weight loss by week 12, with maximum results seen at 12 to 18 months of continued treatment. Individual results vary depending on the medication used, your starting weight and how consistently you follow a healthy diet and exercise plan alongside treatment.

Yes. Weight loss medications are designed to be used alongside a reduced-calorie diet and regular physical activity, not as a replacement for them. Clinical trials for Mounjaro, Wegovy and other treatments all included lifestyle changes as part of the programme. Medication helps reduce appetite and makes it easier to stick to healthier habits. Still, sustainable long-term results depend on building good eating and exercise patterns that continue even after treatment ends. Research shows that most people regain weight after stopping medication if lifestyle changes are not maintained.

NHS access to weight loss medication is available but limited. As of 2026, GPs can prescribe Mounjaro on the NHS, but only to patients who meet strict eligibility criteria based on BMI and the presence of specific weight-related health conditions. Wegovy is available through NHS specialist weight management services in some areas, though waiting times can be long and access varies by region. Most people currently access these treatments faster through private prescription services like Peak Pharmacy's oline prescribing service.
