I apologise in advance for being pedantic, but Irritable Bowel Disease doesn't exist...
There is Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD). They share some similar symptoms (diarrhoea, abdominal pain, gas, bloating), but they are not interchangeable. IBS can be very unpleasant, but it doesn't damage the intestines in the way that IBD does. The treatments are quite different too.
I've seen journalists make that same mistake in news articles, so don't feel bad about it.
