Irritable bowel syndrome (IBS) is a common condition that causes persistent changes to a person’s bowel habits. It is typically caused by stress, sensitive nerves in the gut, or a family history.
But another type of IBS can occur after a person has an infection.
Here’s what you need to know about post-infectious IBS, sometimes called PI-IBS in the medical community. We’ll include a look at what treatments may help and how long the condition may last.
IBS is a group of intestinal issues that can cause cramping.
PI-IBS is a type that starts after an infection, usually within 2 to 3 years. This condition is

With or without treatment, PI-IBS can improve over time.
