Dr Lisa Das is a consultant gastroenterologist at Welbeck's Digestive Health centre in London, specialising in diagnostic endoscopy, bowel cancer screening and general gastroenterology. She assesses and treats a wide range of digestive conditions, including irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) such as Crohn's disease, coeliac disease, acid reflux, gastro-oesophageal reflux disease (GORD/GERD), small intestinal bacterial overgrowth (SIBO), functional gut disorders, and liver conditions. She also investigates symptoms such as abdominal pain, bloating, diarrhoea, constipation, rectal bleeding and changes in bowel habit.
As a nationally accredited bowel cancer screening endoscopist, Dr Das has a particular interest in the early detection and prevention of bowel cancer and offers a comprehensive range of diagnostic investigations, including gastroscopy, colonoscopy, flexible sigmoidoscopy and video capsule endoscopy, which uses a small swallowed camera to examine the small bowel. She also provides Helicobacter pylori breath testing, Bravo/Alpha oesophageal pH testing, functional gut assessment and gut microbiome testing.
A central part of Dr Das's approach is providing accessible, personalised care, with continuity from the initial consultation through to investigations and results. She aims to minimise delays between appointments and diagnostic tests, while ensuring patients feel comfortable discussing potentially sensitive digestive symptoms. She particularly welcomes patients seeking a female gastroenterologist and has a focused interest in women's digestive health.
Traditionally in the UK gastroenterology & endoscopy is performed in hospital resulting in a time consuming and often frustrating patient journey. The purpose of Welbeck Digestive Health is to provide seamless, excellent specialist care in a way that emphasises health, prevention and wellbeing, as well as treating digestive diseases.
Dr Das has extensive clinical experience in both the UK and USA and was the UK's first community gastroenterology consultant, based at the Royal London Hospital, part of Barts Health NHS Trust. After returning to London in 2007, she recognised opportunities to improve access to outpatient gastroenterology services. She joined the Royal London Hospital as a consultant in 2009, where she helped develop more efficient referral pathways, including straight-to-test services designed to reduce the time between referral, diagnosis and treatment. Her work in this area builds on her experience establishing an ambulatory gastroenterology centre in the USA.
When I returned to the UK, my main aspiration was to develop an outpatient endoscopy/gastroenterology facility. I had experience in setting up an ambulatory centre in the USA which was the most professionally stimulating venture I have undertaken.
Dr Das studied medicine at Guy's Hospital Medical School in London before completing her medical residency in Boston, USA, followed by specialist gastroenterology training at Columbia University in New York in 1997. She holds American Board Certification in Gastroenterology and is included on the UK General Medical Council's Specialist Register in Gastroenterology.
