Personalised hormone and gut support & expert medical aesthetics, with weight loss support
Hi, I’m Donna Barleycorn — an Advanced Nurse Practitioner Prescriber and Functional Medicine Clinician, and British Menopause Trained.
I run a UK-based CQC registered women’s health clinic specialising in hormones, perimenopause and menopause, gut health, alongside our weight loss medications and HRT clinic.
I combine clinical medicine with advanced functional testing — including full blood panels, gut health testing, and DUTCH hormone testing — including diagnosis, treatment, lab interpretation, prescribing, and medical management, to get to the root cause of symptoms, not just manage them.
My approach is about giving you accessible, in-depth support so you can truly understand your body and feel your best again.
If you’re ready to take that next step, contact us, or you can book your FREE 15-minute discovery call.
