Weight loss is simpler with SemaPen
On average, SemaPen subscribers lose around 10-21% of their body weight¹ with our non-surgical weight loss treatments.
Are you living with obesity? Have you tried diet and exercise but didn't get the results you wanted? Have you considered bariatric surgery but are worried about going ahead?
One of our weight loss programmes might be right for you.
Designed by doctors in the UK, our medical programmes use clinically proven alternatives to gastric surgery called 'Mounjaro' and 'Wegovy'. These weight loss injection pens are easy to take at home and are safe to use when prescribed by a doctor.

Don't want to go down the medical route? Ineligible for our Wegovy and Mounjaro programmes? We also offer the drug-free SemaHealth programme, which swaps medications for healthy, delicious daily shakes and soups.

Trusted for 20+ years
SemaPen is part of Phoenix Health, the only private bariatric provider trusted to provide NHS treatment.
You'll find lots of online pharmacies offering non-surgical gastric sleeve alternatives like Wegovy and Mounjaro.
However, most pharmacies can only provide limited care. They're not doctors, and they're not set up to deliver targeted, specialised advice about obesity.
That's where SemaPen is different. As part of Phoenix Health, we've helped people on their weight loss journeys for more than 20 years.
With SemaPen, you're not dealing with pharmacists or GPs. You're getting expert care from real weight loss specialists, including doctors, dieticians, psychologists and specialised nurses.
What if I'm not sure what I need?
That's another good reason to choose SemaPen. As part of the trusted Phoenix Health group, we're free to deliver the treatment that suits you best.
That might be a gastric surgery alternative like Wegovy or Mounjaro, or SemaHealth – our specially designed meal replacement programme. Or it could be a weight loss operation performed by one of the UK's top bariatric surgeons.
To get started, download our app to take our free digital consultation. You'll hear back instantly with tailored treatment options from our weight loss specialists.
