Nausea and vomiting - from Natural Standard

Nausea is the unpleasant, painless sensation that one may potentially vomit.

Vomiting is intended to protect a person from harmful ingested substances.

Inflammatory bowel disease

Inflammatory bowel disease (IBD) refers to two chronic diseases that cause inflammation of the intestines - ulcerative colitis and Crohn's disease. The symptoms of these two illnesses are very similar, which often makes it difficult to distinguish between the two. In fact, about 10% of colitis (inflamed colon) cases cannot be diagnosed as either ulcerative colitis or Crohn's disease. When physicians cannot diagnose the specific IBD, the condition is called indeterminate colitis.
