Siobhan O’Farrell is a Nutritional Therapist and Lifestyle Nutrition Coach practising at Siobhan O’Farrell Nutrition in Sligo, Ireland. She is a registered member of the Nutritional Therapists of Ireland (NTOI) and provides personalised nutritional therapy consultations based on evidence-based practice.
She supports individuals with a range of health concerns, including digestive issues such as bloating and irritable bowel symptoms, hormonal imbalances including polycystic ovary syndrome (PCOS), weight management, fatigue, low energy levels, sleep disturbances, and mood-related concerns. Her work also focuses on general health optimisation, including improving digestion, supporting gut health, and addressing nutrient deficiencies.
Her clinical approach is based on nutritional therapy and functional medicine principles, which consider the body as an interconnected system. She assesses underlying factors such as diet, lifestyle, stress, and potential imbalances in digestive, hormonal, and immune function. Treatment involves personalised dietary and lifestyle recommendations designed to address root causes rather than symptoms alone.
Siobhan O’Farrell completed a four-year diploma in Nutritional Therapy alongside training as a Nutrition and Lifestyle Coach. Her work is grounded in evidence-based nutritional science and focuses on long-term, sustainable changes tailored to the individual.

“Evidence-based care tailored to each patient — taking the time to explain options and shared decisions.”

Why local healthcare in Online matters

Medical practice in Ireland is governed by country-specific licensing, professional standards, and patient-safety regulations. Practitioners listed here are registered with the relevant Ireland medical authority and operate within national rules on scope of practice, prescribing rights, and continuing professional development. Care delivered in Online carries the additional benefits of local language support, in-person follow-up, and direct coordination with regional hospitals and labs.
