- a change in how often you have a bowel movement
- changes in the way your stools look
Although there are many ways to treat IBS, the exact cause of IBS is
Possible causes include an overly sensitive colon or immune system. Postinfectious IBS is caused by a previous bacterial infection in the gastrointestinal tract. The varied possible causes make IBS difficult to prevent.
The physical processes involved in IBS can also vary but may consist of the following:
- slowed or spastic movements of the colon, causing painful cramping
- abnormal serotonin levels in the colon, affecting motility and bowel movements
- a bacterial imbalance in the digestive tract
IBS risk factors

Your doctor may be able to diagnose IBS based on your symptoms. They may also take one or more of the following steps to rule out other possible causes of your symptoms:

- order tests to examine your stool sample to rule out infection
- order blood tests to check for anemia and rule out celiac disease

Your nervous system, to a great degree, controls the automatic movement, or motility, of your digestive system. This means that stress can affect your nerves, making your digestive system overactive.
If you have IBS, your colon may be overly responsive to even slight disruptions of your digestive system. It is also believed that IBS is affected by the immune system, which is also affected by stress.

What should people with IBS eat?
For some people, dietary changes can go a long way in helping ease symptoms. This includes eating smaller meals and avoiding foods that trigger symptoms.
A common eating pattern that doctors and registered dietitians recommend for IBS is the low FODMAP diet.
A FODMAP is a kind of carbohydrate found inside certain foods. Studies have shown links between FODMAPs and some common digestive issues.
Because IBS symptoms vary among people with the condition, approaches to dietary changes need to vary.
What medications treat IBS?
If your symptoms do not improve through home remedies, such as lifestyle or dietary changes, your doctor may suggest medication therapy. Different people can respond differently to the same medication, so you may need to work with your doctor to find the right medication for you.
As with all medications, when considering a new treatment option, it’s important to tell your doctor what you are already taking, including herbal remedies and over-the-counter (OTC) medications. This will help your doctor avoid any medication that could interact with what you are already taking.
