I specialise in helping people with complex gut and chronic health issues who have often been told “everything looks normal” — but still don’t feel well.

If you’re struggling with symptoms such as bloating, food intolerances, reflux, fatigue, or unpredictable reactions — and nothing seems to be working — I offer a personalised, root-cause approach to help you understand what’s driving your symptoms and how to improve them.

My work combines clinical dietetics with advanced knowledge of the gut microbiome, inflammation, and multi-system health, supported by my background in Molecular Biology.

I support clients with:

Digestive disorders:
IBS (Irritable Bowel Syndrome), SIBO (Small Intestinal Bacterial Overgrowth), SIFO, IMO, GERD, acid reflux, histamine intolerance, chronic constipation, inflammatory bowel disease (Crohn’s disease, ulcerative colitis)

Autoimmune and inflammatory conditions:
Coeliac disease, Hashimoto’s thyroiditis, Graves’ disease, rheumatoid arthritis, lupus (SLE), Sjögren’s syndrome, multiple sclerosis.

Metabolic health:
Type 2 diabetes, insulin resistance, NAFLD (fatty liver), hyperlipidaemia, cardiovascular disease, obesity, gout, haemochromatosis

Hormonal health:
PCOS, endometriosis, thyroid disorders, perimenopause and menopause

Complex and often underdiagnosed conditions:
Mast cell activation syndrome (MCAS), chronic fatigue syndrome (ME/CFS), Lyme disease and post-infectious syndromes, Ehlers-Danlos syndrome (EDS), chronic multi-system symptoms

My approach is personalised, practical, and designed for people who feel stuck — particularly those who haven’t found answers through standard approaches.
