If you have IBS-D, you feel the belly pain that’s common with irritable bowel syndrome (IBS), and you have to go to the bathroom a lot. The “D” stands for diarrhea.
Some people with IBS have the opposite problem, constipation. That's IBS-C. And some have both, at different times, which is another type of IBS.
There is a wide range of things you can try to help tame your symptoms. It may take some time to hit upon what works best for you, but it can get better.
