Introduction

Most people who are interested in Wegovy for weight loss have one common question: How quickly does Wegovy work?

To answer this, Wegovy starts working inside your body within days. But noticeable weight loss is not overnight because it may take a little longer. You need patience as it gradually builds over time.

Wegovy (semaglutide) is a prescription weight loss injection approved for use in the UK. The medication is originally developed for the treatment of type 2 diabetes in adults that was later found out to have an effect of regulating appetite.

This guide will help you understand exactly how Wegovy starts working, what are the changes you can expect every week, and how dosage can affect your results, and what most people in the UK say about the medication. This will help you set realistic expectations and feel confident about your weight-loss journey.

 

How Wegovy Works

Wegovy works by mimicking a natural hormone in your body called GLP-1 (glucagon-like peptide-1) receptor agonist.

You will experience the following while using Wegovy:

• It signals your brain that you are full sooner.
• Reduces your hunger and food cravings
• Slows down your gastric emptying
• It helps stabilise your blood sugar levels

These combining factors will make you eat smaller portions, and you will stay satisfied for longer – without the need to fight your hunger.

Importantly, using Wegovy will not give you instant weight loss. Instead, it will help you reset your appetite signals gradually. That is why the results will not happen immediately because it builds up over time.

 

Why Dosage Matters

You need to start Wegovy at a lower dose to allow your body to adapt to it. It will help:

• Minimise your side effects, like nausea and digestive discomfort.
• Prevent you to stop the treatment early
• Supports you to get better results

Some people assume that Wegovy is not effective for them or isn’t working because they don’t see much weight loss in their first few weeks of using the medication – but this early phase is designed for hormonal adjustment, and not instant results.

 

Wegovy Dosage Schedule

Starting Dose (Week 1-4: 0.25 mg)

To help your body adjust, you need to start your treatment at a lower dose. Your focus during these first four weeks is not rapid weight loss but reducing the risks of side effects, such as nausea or digestive issues.

 

Dose Escalation

After the starting phase, your dose is gradually increased to improve effectiveness of your weight loss, keeping side effects still manageable for you:

• Weeks 5-8: 0.5 mg
• Weeks 9-12: 1 mg
• Weeks 13-16: 1.7 mg
• Months 5 onwards: 2.4 mg (maintenance dose)

As you notice, the increase is done slowly to help your body adjust comfortably and supports your weight loss steady and sustainable over time.

 

How Quickly Does Wegovy Start Working?

• Hormonal Effects: Days 1–3

After your injection, Wegovy starts working within the first few days even if the number on the scales don’t drop right away.

During this period, many people notice:

• Reduce their hunger between meals
• Feeling full faster
• Less interest in snacking

This only means that the medication is working effectively on you – even if you haven’t lost weight yet.
