Medical specialists detail Irritable Bowel Syndrome diagnosis and symptoms

Medical specialists have detailed the diagnostic process and symptoms of Irritable Bowel Syndrome (IBS), noting that diagnosis is primarily achieved by excluding other digestive diseases. Key warning signs that suggest conditions other than IBS include the presence of blood in the stool, which indicates an evident lesion, and significant weight loss, which suggests an absorption problem rather than a functional motility issue.

Experts highlight a strong correlation between IBS and mental health. Symptoms often manifest during the day, particularly after meals, and tend to disappear during sleep when emotional stimuli are reduced. However, some patients experience persistent abdominal pain that feels as if it has ‘a life of its own’; this occurs because repeated pain signals can become fixed in the central nervous system, leading to intermittent perceptions of pain even during rest.

To confirm an IBS diagnosis, clinicians typically use blood tests to rule out similar conditions such as lactose intolerance or celiac disease.
