Wegovy BMI Requirements and Monthly Cost UK

Published on: June 03, 2026

Understanding wegovy bmi requirements uk cost is essential before starting treatment. At Cured Pharmacy, Wegovy is available from £79.00 per month for eligible patients, with BMI criteria typically requiring 30 kg/m² or above, or 27 kg/m² with weight-related health conditions such as type 2 diabetes or hypertension. Our UK-registered prescribers assess your eligibility during a free online consultation that takes under three minutes.

What BMI Do You Need for Wegovy in the UK?

Wegovy (semaglutide 2.4mg) is licensed by the MHRA for adults with a body mass index of 30 kg/m² or greater, or 27 kg/m² or greater in the presence of at least one weight-related comorbidity [1]. Weight-related comorbidities include type 2 diabetes, hypertension, obstructive sleep apnoea, cardiovascular disease, or dyslipidaemia. These criteria align with NICE guidance on the clinical use of GLP-1 receptor agonists for weight management.

Your BMI is calculated by dividing your weight in kilograms by your height in metres squared. A 75kg person who is 1.70m tall, for example, has a BMI of approximately 26 kg/m². If that individual also has prediabetes or high blood pressure, they may meet eligibility criteria subject to prescriber approval. Our clinical team at Cured Pharmacy, led by superintendent pharmacist Tarun Kumar (GPhC 2233073), assesses each patient individually during the online consultation to ensure Wegovy is clinically appropriate.

It's important to note that BMI is one component of eligibility. UK prescribers also consider your medical history, current medications, contraindications, and previous weight management attempts. Wegovy is not suitable for patients with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 [2].

Wegovy Monthly Cost Breakdown From £69.00

Wegovy is supplied as pre-filled, single-use injection pens. Each pen contains four weekly doses, meaning one pen lasts approximately one month at the maintenance dose. The pen design is discreet and easy to use, with a hidden needle that automatically retracts after injection.

Compared to typical market rates for semaglutide weight loss injections, Cured Pharmacy offers some of the lowest prices guaranteed in the UK. We source all medications directly from UK-licensed wholesalers, ensuring you receive genuine MHRA-approved products at competitive prices without compromising on quality or patient safety.

Transparent Upfront Pricing at Cured Pharmacy

At Cured Pharmacy, Wegovy is priced from £79.00 per month, reduced from the standard £79.00. This price includes your medication, UK prescriber consultation, and discreet next-day delivery across the UK. Unlike some providers, we display prices before you begin the consultation, so there are no hidden costs or surprise fees at checkout.

The monthly cost reflects the dose prescribed by your clinician. Wegovy follows a dose-escalation schedule starting at 0.25mg weekly, increasing gradually over 16 to 20 weeks to the maintenance dose of 2.4mg weekly [1]. Your prescriber will determine the appropriate dose based on your tolerance and clinical response during treatment.

How Wegovy Works for Weight Loss

Wegovy contains semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist that mimics a natural hormone involved in appetite regulation and glucose metabolism [2]. By activating GLP-1 receptors in the brain, Wegovy reduces hunger, increases feelings of fullness after meals, and slows gastric emptying. These combined effects help patients consume fewer calories without the constant hunger that often derails weight loss efforts.

In the landmark STEP 1 clinical trial, adults without diabetes who received semaglutide 2.4mg achieved an average body weight reduction of 14.9% over 68 weeks, compared to 2.4% with placebo [2]. Participants also experienced improvements in waist circumference, blood pressure, and lipid profiles. Nearly one-third of patients lost 20% or more of their initial body weight, a level of reduction previously achievable only through bariatric surgery.

Wegovy is administered once weekly via subcutaneous injection into the abdomen, thigh, or upper arm. The injection takes seconds to complete, and most patients find the process straightforward after the first dose. Clinical trials showed that the most common side effects are gastrointestinal—nausea, diarrhoea, vomiting, and constipation—which typically diminish as your body adjusts to the medication [1][2].

Wegovy BMI Calculator: How to Check Your Eligibility

During your free online consultation at Cured Pharmacy, you'll be asked to provide your height and weight. Our clinical team uses this information, along with your responses to questions about existing health conditions and medications, to assess whether Wegovy is suitable and safe for you. The consultation is completed entirely online, typically in under three minutes, and you'll receive a decision from a UK-registered prescriber within hours.

If your BMI is slightly below the standard threshold but you have documented weight-related health concerns, it's still worth completing the consultation. Our prescribers evaluate each case individually and may approve treatment where clinically justified, subject to MHRA licensing criteria and clinical guidelines.

Calculating Your BMI Accurately

To calculate your BMI, you need your current weight in kilograms and your height in metres. The formula is: BMI = weight (kg) ÷ [height (m)]². For example, if you weigh 90kg and are 1.75m tall, your BMI is 90 ÷ (1.75 × 1.75) = 29.4 kg/m². This falls just below the standard threshold of 30 kg/m², but if you have a weight-related health condition such as type 2 diabetes, you may still qualify at a BMI of 27 kg/m² or above.

Online BMI calculators are widely available and provide instant results, but remember that BMI is a screening tool, not a diagnostic measure. It does not account for muscle mass, bone density, or fat distribution. A UK prescriber will consider your BMI alongside your medical history, waist circumference, and overall health profile when determining eligibility for Wegovy.

Wegovy Eligibility Criteria UK: Beyond BMI

While BMI is the primary eligibility criterion, UK prescribers also assess several other factors before approving Wegovy. You must be aged 18 or over, and you should have attempted weight loss through diet and exercise before starting medication. Wegovy is intended as an adjunct to a reduced-calorie diet and increased physical activity, not a standalone solution [1].

Certain medical conditions preclude the use of Wegovy. These include a personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome type 2, severe gastrointestinal disease, diabetic ketoacidosis, and pregnancy or breastfeeding [2]. If you have a history of pancreatitis, gallbladder disease, or severe renal impairment, your prescriber will carefully weigh the risks and benefits before making a decision.

Wegovy may interact with other medications, particularly those that affect blood sugar levels. If you're taking insulin or sulfonylureas, your prescriber may need to adjust your doses to reduce the risk of hypoglycaemia. Always disclose all current medications, including over-the-counter products and supplements, during your consultation to ensure safe prescribing.

Starting Wegovy: What to Expect in Your First Month

Weight loss with Wegovy is gradual and sustainable. In clinical trials, the majority of weight loss occurred between weeks 20 and 60, with patients continuing to lose weight or maintain their reduced weight through week 68 [2]. Setting realistic expectations—aiming for 1-2kg loss per month after the initial escalation period—helps sustain motivation and adherence.

At Cured Pharmacy, you'll receive your first month's supply after your consultation is approved. Subsequent prescriptions can be issued monthly, with automatic reminders to reorder before your current supply runs out. Our clinical team is available by phone on (+44) 116 4646009 if you have questions or concerns during treatment.

Dose Escalation and Side Effect Management

Wegovy treatment begins with a starting dose of 0.25mg once weekly for the first four weeks. This low initial dose allows your body to adjust gradually and minimises gastrointestinal side effects. Every four weeks, the dose increases: 0.5mg, 1.0mg, 1.7mg, and finally the maintenance dose of 2.4mg at week 17 [1]. If you experience persistent nausea or vomiting at any stage, your prescriber may delay the dose increase until symptoms resolve.

Most patients report mild to moderate nausea during the first few weeks, which typically improves with continued use. Eating smaller, more frequent meals, avoiding high-fat foods, and staying well-hydrated can help manage these symptoms. If side effects become severe or unmanageable, contact your prescriber immediately—they may adjust your dose or recommend supportive measures.
