What do patients say about our programmes?

Menopause Weight Loss Programme

“I started to struggle with weight gain during perimenopause and nothing seemed to work anymore, even though I hadn’t changed my diet. I felt frustrated and stuck.

After joining the programme at 121 Clinic, everything was properly explained and my treatment was tailored to my symptoms. Over time, my appetite became easier to manage and the constant cravings reduced.

The weight loss has been gradual and sustainable, but the biggest difference is how much more in control I feel again. I finally feel like my body is responding.” AC, Bedford

Microdosing Weight Loss Programme

“I was quite nervous about starting treatment, so my clinician recommended a low-dose, gradual approach to help my body adjust.

This microdosing method suited me really well. I had minimal side effects and felt supported throughout the process.

What I noticed first was that food noise reduced significantly — I wasn’t constantly thinking about eating. My portion sizes naturally decreased without forcing it, and my weight has been coming down steadily in a way that feels manageable and realistic.” FK, Beaconsfield

PCOS Weight Loss Programme

“I’ve struggled with PCOS for years and weight loss has always been extremely difficult, even when I was eating well and exercising regularly.

At 121 Clinic, the doctors explained how insulin resistance was affecting my body, which helped everything make sense for the first time. My treatment plan was tailored specifically to my condition.

Since starting the programme, my cravings are more controlled and my weight has been slowly but consistently reducing. I finally feel like I’m working with my body instead of against it.” TM, Teddington

🧠 What Are Medical Weight Loss Treatments?

Medical weight loss treatments are prescription medications used to help regulate appetite, reduce cravings, and support sustainable weight loss in patients who struggle to lose weight through diet and exercise alone.

These treatments are only prescribed after a medical assessment and are commonly used for obesity, hormonal weight gain, and metabolic conditions such as insulin resistance and PCOS.

At 121 Clinic, serving Bedforshire, London, Surrey, and surrounding areas, our experienced GMC-registered doctors provide personalised medical weight loss support. Where clinically appropriate, we may prescribe MHRA-approved weight loss medications in line with NICE guidelines for patients who struggle with:

• Obesity or excess weight

• Menopause-related weight gain

• PCOS (Polycystic Ovary Syndrome)

• Insulin resistance

• Prediabetes

• Weight gain despite diet and exercise

• Increased hunger, cravings, or "food noise"

• Difficulty maintaining long-term weight loss

All treatments are prescribed following a comprehensive medical assessment to ensure they are safe, suitable, and tailored to your individual health needs and weight loss goals.These treatments work best when combined with healthy lifestyle changes and clinical support.

• Have a BMI over 27 with weight-related health conditions
• Struggle with long-term weight loss
• Experience menopause-related weight gain
• Have PCOS or insulin resistance
• Have not achieved results through diet and exercise alone

A consultation is required to confirm suitability.

Which weight loss injection is best for menopause weight gain?

For menopause-related weight gain, treatments such as Mounjaro and Wegovy may be suitable because they help regulate appetite, reduce cravings, and improve portion control.

The best treatment depends on your symptoms, medical history, and weight loss goals. Some patients respond better to one medication than another, so treatment is always personalised.

Which weight loss injection is best for PCOS?

Patients with PCOS often experience insulin resistance and increased appetite, which can make weight loss more difficult.

Medical weight loss treatments may help by improving appetite control and supporting metabolic balance, particularly when combined with lifestyle changes.

Which weight loss injection is best for insulin resistance?

Insulin resistance can lead to weight gain and difficulty losing weight due to hormonal and metabolic changes.

Treatments such as GLP-1 based medications may support appetite regulation and help improve weight management in suitable patients.

How much weight can I lose with Mounjaro?

Clinical studies have shown that some patients can lose 15–20% or more of their starting body weight when combined with healthy lifestyle changes. Individual results vary.

Can menopause cause weight gain?

Yes. Hormonal changes during menopause can slow metabolism, alter fat distribution, increase appetite, and contribute to weight gain, particularly around the abdomen.

Why am I not losing weight despite dieting?

Several factors may contribute, including insulin resistance, hormonal changes, menopause, PCOS, poor sleep, stress, medications, metabolic adaptation, and underlying medical conditions.

Is Mounjaro better than Wegovy?

Both are effective treatments. Current evidence suggests Mounjaro may produce greater average weight loss in some patients, but suitability depends on individual health needs and medical history.

Can people with PCOS use weight loss injections?

Many women with PCOS may be suitable candidates for weight loss injections. A medical consultation is required to determine the safest and most appropriate treatment.

What is Mounjaro?

Mounjaro (tirzepatide) is a prescription-only, once-weekly injection used for medical weight management. It works by mimicking two natural hormones (GLP-1 and GIP) that help regulate appetite, blood sugar levels, and digestion.

By reducing hunger and increasing feelings of fullness, Mounjaro can help patients eat less, manage cravings more effectively, and support sustainable weight loss when combined with a healthy lifestyle and medical supervision.

Why is Mounjaro expensive?

Mounjaro (tirzepatide) is a relatively new, patented prescription medication, which is one of the main reasons for its higher cost compared to older weight loss treatments.

It is also expensive because it is a highly advanced dual-action drug that works on two hormones (GLP-1 and GIP), requiring significant research, development, and clinical trials to bring to market.

When did the price of Mounjaro increase in the UK?

The price of Mounjaro (tirzepatide) in the UK increased significantly from September 2025 mainly due to a manufacturer-led price realignment by Eli Lilly.

Why did the price of Mounjaro increase in the UK?

The price of Mounjaro increased in the UK mainly due to a manufacturer-led pricing adjustment by Eli Lilly to bring UK pricing closer in line with international markets. The original UK launch price was relatively low compared to other countries.

Other contributing factors include rising global demand for GLP-1 weight loss medications, limited supply, and changes in pharmaceutical pricing strategy across different regions.

Where can I get Mounjaro in the UK?

Mounjaro (tirzepatide) is a prescription-only medication, so you cannot buy it over the counter in the UK. It can only be accessed after a clinical assessment by a qualified prescriber such as 121 Clinic.

Wegovy is a once-weekly GLP-1 injection designed to support appetite control and gradual weight loss. Benefits: Clinically proven weight loss support, Reduced hunger and portion sizes, Easy once-weekly dosing, and Well-established safety profile.
