Dr Leena Sinha

• As a senior consultant gastroenterologist with over two decades of NHS and private sector experience, I offer comprehensive and compassionate care to patients across London and Essex. My clinical practice combines medical excellence with a holistic, patient-centred approach—underpinned by clear, empathetic communication at every stage. My areas of expertise include: • Inflammatory Bowel Disease (IBD) – Clinical Lead and Principal Investigator in IBD research • Diagnostic and therapeutic endoscopy, including capsule and colon capsule endoscopy • Functional and nutritional gut health • Complex gastroenterological diagnostics and multidisciplinary management I work across top-tier private hospitals including Nuffield Health, Spire, and The London Clinic. In addition to delivering high-quality care, I advocate for innovation, medical education, and continuous service development—demonstrated by my leadership roles in endoscopy and IBD services, and my role as Chair of the BSG Small Bowel & Nutrition Section (2022–2024). My ethos is simple: treat the patient, not just the disease. I strive to ensure every individual feels heard, informed, and empowered in their care. Clinical Services • Diagnosis and management of gastrointestinal conditions including IBD (Crohn’s disease and ulcerative colitis), irritable bowel syndrome, reflux, dyspepsia, coeliac disease, gastrointestinal bleeding, and nutritional disorders. Advanced diagnostic procedures including: • Upper and lower diagnostic and therapeutic endoscopy • Capsule endoscopy and colon capsule for small and large bowel assessment • Bowel cancer screening and polyp surveillance • Liver disease management, including fatty liver and viral hepatitis • Functional gut health optimisation, informed by my postgraduate training in nutrition • Clinical support for complex and multi-system presentations, with careful liaison with surgical and medical colleagues • Virtual consultations, second opinions, and follow-up care What Makes My Practice Stand Out IBD Leadership: Former Clinical Lead for IBD at a major UK teaching hospital, where I introduced: IBD Hot Clinics and Virtual Biologics Clinics IBD app for patient engagement CNS-led daily ward cover and enhanced IBD nurse team Evidence-based protocols and multidisciplinary pathways Capsule Endoscopy Expertise: Pioneered and expanded a high-volume capsule endoscopy service, including the introduction of colon capsule for minimally invasive large bowel assessment—helping patients avoid unnecessary procedures. Endoscopy Service Development: As Endoscopy Lead, I led my department to JAG accreditation, implemented safety protocols (including the Endoscopy Safety Checklist), and introduced training for nurse and non-medical endoscopists. Research & Innovation: Principal Investigator for national IBD research studies (e.g., LUCENT, SPIT, and IBD BioResource), contributing to cutting-edge treatment strategies and access to novel therapies. Education & Governance: Passionate about teaching, I have developed formal induction and training frameworks for junior doctors and regularly contribute to clinical governance, service audits, and ethical medical leadership. Private Practice Locations I currently see private patients at several leading London and Essex centres including: Nuffield Health (Brentwood, St Bartholomew’s and The Holly Hospital) Spire London East and Hartswood Hospitals The London Clinic, Harley Street
