Dr Sinha qualified from the University of Wales in 1993 and underwent extensive training in both gastroenterology and general internal medicine within the North West Deanery, gaining experience and honing her skills in the management of common and complex gastrointestinal conditions. In 2007 she earned a specialist teaching qualification from the University of Wales, the PCME, and pursued a further postgraduate diploma in Nutrition at the University of Surrey, which was awarded in 2013.

Dr Sinha has trained in endoscopic techniques for use in diagnostic and therapeutic procedures such as gastroscopy, flexible sigmoidoscopy, colonoscopy, and capsule endoscopy, and has performed tens of thousands of these procedures. She was Chair of the British Society of Gastroenterology (BSG) Committee’s Small Bowel & Nutrition Section, is a committee member of the BSG’s Gastroduodenal Society, and contributes to the RCP Committee in Ethical Medicine. Dr Sinha spearheaded the expansion of the capsule endoscopy service at the Barking, Havering and Redbridge University Hospitals NHS Trust.
