What Causes Irritable Bowel

Irritable bowel syndrome (IBS) is a chronic disorder that affects the digestive system. It causes abdominal pain, diarrhoea, and constipation. While the exact cause of IBS is unknown, several factors are thought to play a role, including:

Gut microbiota imbalances: The gut microbiota is a collection of trillions of bacteria, viruses, and other microorganisms that live in the intestines. Imbalances in the gut microbiota, such as having too much or too little of certain types of bacteria, have been linked to IBS.

Intestinal inflammation: Some people with IBS have inflammation in the intestines. This inflammation can damage the intestinal lining and lead to symptoms such as pain, diarrhoea, and constipation.

Nervous system dysfunction: The nervous system controls the digestive system. Problems with the nervous system, such as increased sensitivity to pain or abnormal muscle contractions in the intestines, can lead to IBS symptoms.

Genetic factors: IBS may be linked to genetic factors, as it often runs in families. However, the exact genes involved are not fully understood.

Psychological factors: Stress, anxiety, and depression can worsen IBS symptoms. It is not clear whether these psychological factors cause IBS or if IBS leads to these psychological problems.

It is important to note that IBS is a complex disorder and the exact cause may vary from person to person. More research is needed to fully understand the causes of IBS and how to treat it effectively.
