Frequently asked questions
1

Is this a prescription service?

This is a medical treatment. A prescription may be issued only if a UK-registered prescriber decides it is appropriate and safe for you after reviewing your medical information.
2

How quickly will I receive a decision?

After you submit your questionnaire, a prescriber reviews your details. If any information is missing or needs clarification, you’ll be contacted before a decision is made. Timeframes may vary depending on individual circumstances.

What will it cost?

You’ll be shown all fees clearly before choosing to proceed. If a prescription is issued, the treatment cost will be displayed transparently. No payment is taken until you confirm you wish to continue.

Can you guarantee weight loss?

No. Weight management outcomes vary from person to person. Prescription medicines are just one part of a broader plan, which should include a healthy diet, regular activity, and lifestyle support.

Yes, with your consent. We can share relevant prescribing or monitoring information with your GP to support coordinated and safe ongoing care.

The Weight Loss Treatment combines the use of weight loss medication to help suppress appetite and should be used along with exercise and better nutritional habits. By addressing the key areas of weight, you’ll have the tools to help you achieve sustainable weight loss.
8

What are weight loss injections?

Weight loss injections are medications delivered via injection that help reduce body weight by suppressing appetite, improving insulin sensitivity, or enhancing metabolism.
9

How do weight loss injections work?

They typically mimic hormones that regulate hunger and glucose, helping you feel fuller for longer and reducing calorie intake.
10

Are weight loss injections effective for losing weight?

Yes, clinical trials show they can result in 10-20% weight loss over time when combined with lifestyle changes.
11

What are the most common types of weight loss injections?

Semaglutide (Ozempic/Wegovy), liraglutide (Saxenda), and tirzepatide (Mounjaro/Zepbound).
12

What is semaglutide (Ozempic/Wegovy)?

A GLP-1 agonist that mimics a hormone involved in appetite control and blood sugar regulation.
13

How is tirzepatide (Mounjaro/Zepbound) different from semaglutide?

It acts on both GLP-1 and GIP receptors, offering greater weight loss potential in some users.
14

How quickly do weight loss injections start working?

Most users begin to see changes within 4–12 weeks.
15

Do I need a prescription for weight loss injections?

Yes, they require a doctor's prescription in most countries.
16

Are weight loss injections safe?

Generally, yes, but they should be used under medical supervision due to potential side effects.

What is the difference between Ozempic and Wegovy?

Same active ingredient (semaglutide), but Wegovy is specifically approved for weight loss at a higher dose.
18

What is Mounjaro and how does it help with weight loss?

19

Are there natural or homeopathic weight loss injections?

Some claim to exist, but they are not clinically proven or regulated.
20

What’s the difference between GLP-1 and GIP medications?

GLP-1 targets satiety and glucose regulation; GIP enhances insulin secretion. Some drugs combine both.
