Irritable Bowel Syndrome affects gut-brain interaction

Irritable Bowel Syndrome (IBS) is a chronic functional disorder characterized by a disruption in the interaction between the brain and the gut. Rather than being caused by visible damage or infection in the digestive tract, the condition involves abnormalities in how the nervous system and brain process signals from the intestines.

Common symptoms include recurrent abdominal pain, bloating, gas, and changes in bowel habits, such as diarrhea, constipation, or a mixture of both. Some reports indicate that IBS may also manifest through less common symptoms like headaches, back pain, and muscle aches. Diagnosis often relies on assessing the duration and nature of symptoms, such as pain occurring at least once a week for three months, while medical tests are used to rule out other conditions like celiac disease or inflammatory bowel disease.

Factors such as stress, gut microbiota composition, intestinal permeability, and motility issues may contribute to the condition. While stress can exacerbate symptoms, experts emphasize that the disorder is a physical functional issue rather than a psychological one.
