This is a term popularly used by people to describe a condition that is characterized by headache, nausea, vomiting, disturbed stomach, and general malaise. However, this condition has nothing to do with bile secretion or excess of it. Sometimes, bile might be accompanied with vomiting, and this is misunderstood for excess bile secretion. Incidentally, during vomiting, bile tends to get drawn into the esophagus and thus it shows up in the vomit. The treatment for biliousness generally depends on the symptoms.
