How Wegovy Semaglutide Works for Weight Loss

Wegovy contains semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist licensed by the MHRA for chronic weight management in adults with a BMI of 30 kg/m² or greater, or 27 kg/m² with at least one weight-related comorbidity [1]. Semaglutide mimics the natural GLP-1 hormone, which regulates appetite by acting on areas of the brain that control hunger and food intake, while also slowing gastric emptying to increase feelings of fullness.

In the landmark STEP 1 clinical trial, participants receiving once-weekly semaglutide 2.4 mg achieved an average body weight reduction of 14.9% over 68 weeks, compared to 2.4% with placebo [1]. This represents one of the most significant weight reductions observed in any pharmacological weight management trial to date. The treatment works most effectively when combined with a reduced-calorie diet and increased physical activity, as recommended by NICE guidelines for obesity management [2].

Wegovy is administered as a subcutaneous injection once weekly, using a pre-filled pen device designed for self-administration. The dose is gradually increased over 16 to 20 weeks, starting at 0.25 mg and building to the maintenance dose of 2.4 mg weekly. This titration schedule minimises gastrointestinal side effects, which are the most commonly reported adverse reactions during initial treatment phases [3].

Wegovy Dosing Schedule and Administration

The Wegovy dosing regimen follows a structured escalation protocol designed to optimise tolerability whilst achieving therapeutic efficacy. Treatment begins at 0.25 mg once weekly for four weeks, then increases to 0.5 mg for four weeks, followed by 1 mg, 1.7 mg, and finally the maintenance dose of 2.4 mg [3]. Each dose escalation occurs at four-week intervals, allowing your body to adjust gradually to the medication.

If you experience persistent gastrointestinal symptoms during dose escalation, your UK prescriber may recommend delaying the increase by an additional four weeks. The injection can be administered at any time of day, with or without meals, though maintaining a consistent day each week helps establish routine adherence. Injection sites include the abdomen, thigh, or upper arm, and should be rotated weekly to reduce the risk of lipodystrophy at injection sites.

What to Expect During Treatment

Most patients notice reduced appetite within the first few weeks of treatment, though significant weight loss typically becomes apparent after reaching higher doses. Clinical trial data shows that approximately 86% of participants achieved at least 5% body weight reduction, whilst 69% achieved 10% or greater reduction by week 68 [1]. Your UK prescriber will monitor your progress at regular intervals, typically reviewing weight loss after 12 weeks on the maintenance dose to assess treatment response and determine whether continuation is appropriate.

Wegovy vs Mounjaro: Comparing GLP-1 Weight Loss Treatments

Both Wegovy and Mounjaro represent advanced pharmacological options for weight management, though they differ in their mechanisms of action. Wegovy contains semaglutide, a selective GLP-1 receptor agonist, whilst Mounjaro contains tirzepatide, a dual glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptor agonist [4]. This dual action may explain why tirzepatide demonstrated greater weight reduction in head-to-head trials, with patients achieving up to 22.5% body weight loss in the SURPASS-2 study [4].

However, both medications require subcutaneous injection once weekly and share similar side effect profiles, predominantly gastrointestinal symptoms including nausea, diarrhoea, and constipation. The choice between treatments depends on individual medical history, treatment goals, cost considerations, and prescriber assessment. Some patients who experience inadequate weight loss or intolerable side effects with one medication may respond better to the alternative.

At Cured Pharmacy, our UK prescribers evaluate your complete medical history, current medications, weight loss goals, and any previous treatment responses to recommend the most appropriate option. Both treatments are prescription-only medications that require ongoing clinical supervision, with regular review appointments to monitor efficacy, tolerability, and any emerging safety concerns.

Who Can Use Wegovy?

Wegovy is licensed for adults with a BMI of 30 kg/m² or greater, or 27 kg/m² or greater with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or obstructive sleep apnoea [2]. It is not suitable for patients with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2, or those with severe gastrointestinal disease. Your UK prescriber will assess contraindications during your online consultation to ensure safe prescribing.

Common Side Effects and How to Manage Them

Gastrointestinal side effects are the most frequently reported adverse reactions with Wegovy, occurring in approximately 44% of patients in clinical trials [3]. These typically include nausea, diarrhoea, vomiting, constipation, and abdominal pain, with symptoms usually most pronounced during dose escalation phases and diminishing over time as tolerance develops. Most gastrointestinal symptoms are mild to moderate in severity and resolve without discontinuation.

To minimise nausea and other digestive symptoms, eat smaller, more frequent meals rather than large portions, avoid high-fat and heavily spiced foods, and stay well-hydrated throughout the day. If nausea persists, your prescriber may recommend remaining at your current dose for an additional four weeks before escalating further. Anti-emetic medications are rarely necessary but can be considered for persistent symptoms that affect quality of life.

Other reported side effects include injection site reactions, fatigue, dizziness, and headache. Hypoglycaemia can occur in patients taking concomitant insulin or insulin secretagogues, requiring dose adjustments of these medications. Rare but serious adverse events include pancreatitis, gallbladder disease, and acute kidney injury, typically in the context of severe dehydration from gastrointestinal symptoms. Any severe abdominal pain, persistent vomiting, or signs of dehydration warrant immediate medical attention.

Long-Term Weight Management and Treatment Duration

Wegovy is intended for long-term use as part of a comprehensive weight management programme that includes dietary modification and increased physical activity. Clinical trial data demonstrates that weight loss continues progressively through the first 60-68 weeks of treatment, after which most patients achieve a weight plateau at their new lower body weight [1]. Discontinuation of treatment typically results in gradual weight regain, highlighting the chronic nature of obesity and the need for sustained pharmacological intervention in many patients.

NICE guidance recommends reviewing treatment response after 12 weeks on the maintenance dose, with continuation appropriate only if patients have achieved at least 5% body weight reduction from baseline [2]. For patients who achieve their target weight and wish to discontinue treatment, a gradual dose reduction may help minimise rebound weight gain, though this approach has not been formally studied in clinical trials. Your UK prescriber will discuss long-term treatment plans, monitoring requirements, and strategies for weight maintenance during your ongoing consultations.

Regular follow-up appointments allow your prescriber to monitor treatment efficacy, assess tolerability, screen for adverse events, and provide behavioural support for sustainable lifestyle changes. Blood pressure, lipid profiles, and glycaemic control often improve alongside weight reduction, potentially allowing dose reductions or discontinuation of other medications used to manage obesity-related comorbidities. This holistic approach to weight management optimises both short-term weight loss and long-term metabolic health outcomes.
