Weight loss medications at Voy

GLP-1 stands for glucagon-like peptide-1. It’s a natural hormone your body releases after eating. GLP-1 helps control blood sugar, slows digestion, and reduces appetite, which is why GLP-1 medications are so effective for weight loss.

There’s no one-size-fits-all answer. The best injection depends on your health needs, lifestyle, and how your body responds to treatment.

Mounjaro (tirzepatide) currently shows the most weight loss in clinical trials, with some people losing over 20% of their body weight. That said, effectiveness can vary between individuals, and other medications like Wegovy and Saxenda are also highly effective.

A Voy, our team of clinicians will help you find the best fit based on your medical history and goals.

It varies by medication and the person, but most people can expect to lose between 5% and 15% of their body weight over several months, with some losing even more.

Here’s a breakdown by medication:

- Mounjaro week-by-week weight loss
- Wegovy week-by-week weight loss
- Saxenda monthly weight loss

All medications offered by Voy - including Mounjaro, Wegovy, and Saxenda are clinically approved and prescribed based on safety guidelines. Your clinician will review your health history to make sure treatment is safe for you. If it’s not the right option, they’ll let you know.

Most people tolerate weight loss injections well, but like any medication, side effects can happen especially in the first few weeks. The most common include nausea, constipation or diarrhoea, fatigue, and changes in appetite.

Each medication has slightly different side effect profiles. You can read more about specific ones here:

- Mounjaro side effects
- Wegovy side effects
- Saxenda side effects
- Orlistat side effects

Your clinician will talk you through what to expect and help manage any side effects if they arise.

You may be eligible if:

• You have a BMI of 30 or above, or
• A BMI of 27 or above with a weight-related condition (like high blood pressure, prediabetes, or PCOS)

Your eligibility will be assessed by a clinician as part of a full health review to make sure treatment is safe and suitable for you.

The first step is a clinical assessment. At Voy, you’ll fill out a short online questionnaire which is reviewed by a qualified clinician. If eligible, you’ll get a personalised treatment plan including support beyond just the injection.

On the NHS, Wegovy is approved for people with a BMI over 35 and a weight-related condition, under specialist weight management services. Orlistat is also available for some patients via GPs and can be bought from your pharmacy over the counter. Access can vary depending on your location and local NHS services.
