Wegovy is clinically proven to help with weight loss. How? It acts like a natural hormone your body uses to regulate blood sugar and appetite—key steps in resetting your biological set point to help you maintain a new, lower weight.
Semaglutide mimics GLP-1, the gut hormone that slows digestion and tells your brain you have eaten enough.
Inject under the skin of your stomach, thigh or upper arm once a week, changing the spot each time. Keep unopened pens in the fridge and never freeze them.
The most frequent are nausea, vomiting, diarrhoea, constipation, indigestion, abdominal pain, bloating/burping, headache, dizziness and fatigue. These are usually mild-to-moderate and improve as your body adjusts.

What people say,
in their own words
“Very easy process. A short questionnaire, a quick review from the prescriber, and it arrived two days later with tracking the whole way.”
“I can’t rate heySlim highly enough. The messages I’ve had with my prescriber have been frequent and genuinely helpful. I’ve never waited long for a reply, and when I had a question about a blood test he looked over the results for me.”
“What stood out was having one prescriber who actually follows my progress. She was so reassuring in the first few weeks, answered everything quickly and adjusted the plan when I asked.”
“Approved the same day and the medication was with me the morning after. Plain box, no fuss. Couldn’t have been simpler.”
“heySlim have been brilliant from the start. Clear about what to expect, they check in every few weeks and reordering takes about a minute.”
“I liked how thorough the checks were. It made me confident that what I was buying was legitimate and that someone qualified had looked at my history. The price is fair too, not inflated because they can.”
“Fab service. Super quick approval and lovely people. I had a delivery address query and the advisor on chat sorted it in minutes.”
“No issues with delivery, ever. Communication has been fantastic, there to advise if I need it, and they keep a check on you by email. Very happy.”

Check your eligibilityIn the UK, Wegovy® (semaglutide) is a prescription-only, once-weekly injection licensed for chronic weight management in adults with obesity or who are overweight with weight-related health problems. It is used alongside a reduced-calorie diet and increased physical activity.
Wegovy® contains semaglutide, a GLP-1 receptor agonist. It mimics a natural gut hormone that helps regulate appetite and fullness, slows stomach emptying, and supports steadier post-meal blood sugar—making it easier to eat less and lose weight when combined with lifestyle changes.
Adults (18+) with BMI ≥30, or BMI ≥27 with a weight-related condition (e.g., hypertension, dyslipidaemia, sleep apnoea, prediabetes/type 2 diabetes) may be considered after a clinical assessment. Final suitability depends on your medical history and current medicines.
Results vary, but pivotal trials of semaglutide alongside lifestyle changes showed meaningful average weight loss across 68 weeks. Your outcome depends on dose, adherence, nutrition, activity and individual response.
Typical titration: 0.25 mg once weekly for 4 weeks, then 0.5 mg for 4 weeks, 1.0 mg for 4 weeks, 1.7 mg for 4 weeks, then up to 2.4 mg once weekly if tolerated. Your prescriber may pause or slow increases to manage side effects.
Inject subcutaneously (under the skin) into the abdomen, thigh, or upper arm. Rotate injection sites weekly and avoid injecting into areas that are tender, bruised, scarred or hardened.
You may change your dosing day if there are at least 48 hours between injections. Once you pick a new day, keep it weekly and consistent. For the most up-to-date information, always check your medication's leaflet.
If you’re ≤5 days late, take the dose as soon as you remember and continue your usual schedule. If >5 days late, skip the missed dose and take the next dose on your usual day. If you miss 2 or more doses, contact your prescriber—you may need to re-titrate. For the most up-to-date information, always check your medication's leaflet.
Many people feel reduced appetite within 2–4 weeks. Visible weight change often appears after 4–8 weeks and tends to increase as the dose is gradually stepped up.
The most frequent are nausea, vomiting, diarrhoea, constipation, indigestion, abdominal pain, bloating/burping, headache, dizziness and fatigue. These are usually mild-to-moderate and improve as your body adjusts.
