Professor Qasim Aziz
Consultant Gastroenterologist & Neurogastroenterologist
MD, FRCP, PhD.
About me
Professor Qasim Aziz is a Consultant Gastroenterologist and one of the UK’s best-known leaders in neurogastroenterology, the specialist field focused on disorders of gut-brain interaction, visceral pain and gastrointestinal motility. He is Professor of Neurogastroenterology at Barts and The London School of Medicine and Dentistry (Queen Mary University of London) and The Former Director of the Wingate Institute of Neurogastroenterology, a centre recognised internationally for research and specialist care.
Patients often seek Professor Aziz when symptoms have become persistent, complex, or difficult to explain, including IBS-type symptoms, functional dyspepsia, chronic abdominal pain, reflux symptoms that don’t fit a clear pattern, or motility problems that require expert investigation. His work is grounded in modern understanding of the gut-brain axis, and his research has contributed to how clinicians interpret and treat visceral hypersensitivity and chronic gut pain.
Professor Aziz trained in gastroenterology in Manchester and has held senior academic and clinical posts over many years, including appointment as Professor of Gastroenterology at the University of Manchester (2004) and later appointment at Barts and The London (2006).
At LSDC Healthcare near Liverpool Street, he provides discreet, consultant-led assessment with a focus on precision diagnostics, clear explanations, and structured management plans that patients can realistically follow.
Professional Experience
Professor Aziz holds an NHS consultant post at Barts Health NHS Trust and has been Professor of Neurogastroenterology at Barts and The London (QMUL) since 2006.
He is The Former Director of the Wingate Institute of Neurogastroenterology, and his academic work has been recognised with major awards including the Sir Francis Avery Jones Research Gold Medal (British Society of Gastroenterology, 1998) and the Janssen Award for Basic and Clinical Research (American Gastroenterological Association, 2000).
His research focus includes the neurophysiological basis of gut-brain communication and the mechanisms of visceral pain, work that has supported clinical understanding of chronic abdominal pain and symptom generation in functional gastrointestinal disorders.
Professor Aziz has also held roles within major professional societies in neurogastroenterology and European gastroenterology education committees, reflecting long-term leadership within the specialty.
Qualifications & Academic Background
Professor Aziz completed undergraduate medical training and was awarded an MD (1983), then undertook higher medical training in the UK. He began his research career at the University of Manchester and obtained a PhD in 1996.
He is a Fellow of the Royal College of Physicians (FRCP) and is GMC-registered (GMC reference number 3519619).
Academic and clinical appointments include long-standing roles at Barts and The London School of Medicine and Dentistry (QMUL), where he leads research and clinical strategy within neurogastroenterology.
Specialist Expertise
Professor Aziz is widely recognised for expert assessment and management of disorders of gut-brain interaction, including complex symptom patterns where standard investigations may be normal but symptoms persist.
His specialist expertise includes:
- Irritable bowel syndrome (IBS) and IBS-type symptoms
- Functional dyspepsia and persistent upper abdominal discomfort
- Chronic abdominal pain and visceral hypersensitivity
- Motility disorders (abnormal gut movement)
- Reflux disease and complex reflux symptoms
- Non-cardiac chest pain related to oesophageal function
- Gut symptoms associated with systemic disease (including diabetes and connective tissue disorders)
A particular area of interest is gastrointestinal symptom burden in patients with joint hypermobility syndromes, including hypermobility spectrum disorders and Ehlers-Danlos–related presentations. His work has helped build clinical insight into how these conditions can overlap with functional gastrointestinal symptoms.
Where appropriate, Professor Aziz can guide patients through targeted investigation planning (rather than broad “tick-box” testing) and interpret results in the context of symptoms, lifestyle, and physiology, especially important in IBS, functional dyspepsia and chronic gut pain.
Present Moment
Professor Aziz is currently seeing patients in London for consultant-led gastroenterology and neurogastroenterology assessment, including complex abdominal pain, IBS, functional dyspepsia, reflux symptoms and suspected motility disorders. His present focus remains on helping patients achieve diagnostic clarity and a practical management plan, particularly when symptoms persist despite previous testing.
Patients who see Professor Aziz at LSDC Healthcare benefit from rapid coordination of investigations and access to specialist blood tests and targeted diagnostic panels. LSDC also offers transparent self-pay pricing and clinic-bundled investigation packages that may be more cost-effective than standard private-hospital itemised tariffs.
Subspecialities
- Neurogastroenterology (gut–brain disorders)
- Irritable bowel syndrome (IBS) and disorders of gut-brain interaction
- Chronic abdominal pain, visceral hypersensitivity and functional GI disorders
- Motility disorders and complex reflux / oesophageal symptoms
- GI symptoms in hypermobility spectrum disorders / joint hypermobility syndromes
Patient Approach
Professor Aziz is known for an analytical, steady consultation style that patients find reassuring, particularly when symptoms have been long-standing or difficult to explain. He prioritises:
- Careful history-taking and symptom pattern recognition
- Targeted investigations that genuinely change management
- Clear explanation of results, including what they do (and do not) mean
- Practical, evidence-based plans that consider work, stress, sleep and diet without oversimplifying complex physiology
His goal is to help patients move from uncertainty to clarity, with a plan that balances medical treatment, lifestyle strategy and appropriate follow-up.

What Professor Aziz helps with
Consultant-led neurogastroenterology in London for complex digestive symptoms, especially when previous tests are normal yet symptoms persist. This is specialist care for disorders of gut-brain interaction, visceral pain and motility concerns, with a clear plan and structured follow-up.
Bloating, abdominal pain, diarrhoea, constipation or mixed bowel habit, assessed with a specialist gut–brain approach, not a one-size-fits-all label.
Persistent or recurring pain and visceral hypersensitivity patterns, with careful risk assessment, targeted testing and practical symptom control strategies.
Heartburn, regurgitation, indigestion, nausea or upper abdominal discomfort, especially when symptoms don’t respond as expected or feel “atypical”.
Suspected delayed or disordered gut movement, persistent fullness, early satiety or constipation patterns that require specialist interpretation.
Non-cardiac chest pain and swallowing-related symptoms where oesophageal function and gut–brain signalling may be contributing factors.
Specialist review when digestive symptoms overlap with joint hypermobility presentations and complex multisystem concerns.
If you have alarm symptoms (significant bleeding, black stools, severe worsening pain, persistent vomiting, fever, fainting, or unintended weight loss), please seek urgent medical assessment.
