Wegovy uses a step-by-step 5-stage dosing schedule. This gradual increase helps your body adjust and reduces the chance of nausea or digestive side effects.
This is the starter dose. Its purpose is tolerance, not weight loss.
Most people notice reduced hunger during this phase.
Appetite reduction becomes more noticeable.
Side effects usually remain mild.
This is where weight loss typically begins to accelerate.
Patients often report stronger weight-loss momentum at this dose.
Wegovy titration does not need to occur on a fixed monthly schedule.
Dose progression is individualised, based on tolerability, side effects, and clinical response. Some patients may remain on the same dose longer or delay escalation to ensure safety and comfort.
Results vary based on lifestyle, dose, and adherence, but clinical trials show:
Average weight loss: 10-15% of starting body weight

Additional improvements often include:
Most people notice visible changes at 4-6 weeks, with significant results after 3-6 months.

Mild nausea is one of the most common Wegovy side effects, especially during the first few weeks or after a dose increase. Eating slowly, choosing lighter meals, avoiding greasy foods and staying hydrated usually helps. However, if nausea becomes severe, lasts for several days, or stops you from eating, contact the prescribing doctor - you may need to stay on your current dose longer before increasing.
Yes, alcohol is not strictly prohibited with Wegovy, but it may worsen common side effects such as nausea, reflux or stomach discomfort. Alcohol is also high in calories, which can slow your weight-loss progress. If you drink, it’s best to keep it moderate and avoid drinking on the day you take your injection.
In clinical studies, patients using Wegovy alongside lifestyle changes achieved an average of 10-15% weight loss, far beyond what is typically seen with diet-only approaches. Many people report a noticeable reduction in appetite within the first few weeks, with steady fat loss over several months as the dose increases.
Wegovy has different rules to Mounjaro.If 5 days or less have passed since your missed dose: take it when you remember.If more than 5 days have passed: skip the dose and inject on your next scheduled day. Do not take two doses together. If missed doses happen often, speak to your doctor about adjusting your routine.
As part of our clinical approach to ensure your safety, we typically discontinue treatment once a patient reaches a healthy Body Mass Index of 23. At that stage, your focus should shift to supporting your long-term success through sustainable lifestyle measures, including nutrition and exercise. Emerging clinical evidence suggests that, for some patients, a lower “maintenance dose” of GLP-1 therapy may support weight-loss maintenance more effectively than stopping altogether. That said, current regulatory guidance has not yet approved GLP-1 medications specifically for weight maintenance, and the available research is still limited.
