What is IBS-D?

IBS-D stands for irritable bowel syndrome with diarrhea.

It is a common disorder of the large intestine (colon). If you think you may have IBS-D, you’re not alone. It is believed to affect more than 16 million Americans.

IBS-D symptoms can happen on a regular basis and vary widely from one person to the next. But they often include abdominal pain and diarrhea.

The precise cause of IBS is not known, though it’s believed that various factors can play a role in creating symptoms. Too strong or weak intestinal muscle contractions, inflammation or severe infection in the intestines, and even improper signaling from your brain to your intestines are all possible causes. Another possible cause is believed to be an imbalance in the bacteria in your digestive system.

There’s no one profile for a person who will develop IBS-D, but
