What Is Irritable Bowel Syndrome?
3. Infection
Our digestive systems naturally harbor bacteria and other microorganisms. These are not usually harmful to us and, in many cases, they are even beneficial. Indeed, without them, we would have difficulty digesting our food. While they are mostly welcome, however, they can still sometimes cause problems and become very unwelcome.
Irritable bowel syndrome may sometimes be down to an imbalance in the population of microorganisms in the digestive system. Some types can proliferate beyond usual numbers under certain conditions, and this can cause problems for us. Other types of bacterial or viral infections may also sometimes be responsible for IBS.
