Gastroenterological disorders may lead to anaemia through chronic blood loss, impaired absorption of essential nutrients or long-term inflammation. Identifying the underlying cause is important, as anaemia may sometimes be the first sign of a digestive condition.

Underwater colonoscopy: what it is and how it differs from standard colonoscopy

Colonoscopy remains the gold standard for detecting and monitoring conditions affecting the large bowel, such as colorectal cancer, polyps, and inflammatory bowel disease. However, advances in technique have led to refinements that can improve patient comfort and the quality of the procedure. One such technique is the underwater colonoscopy, which is gaining attention for its potential benefits over traditional methods, as a consultant gastroenterologist explains in this article.

Food intolerances and their symptoms

Food intolerances are reactions to certain foods that occur because the digestive system struggles to process specific ingredients. Unlike food allergies, which involve the immune system and can cause severe or even life-threatening reactions, food intolerances usually cause digestive and other mild-to-moderate symptoms, depending on the type and amount of food consumed.
