While vomit is a definite sign that something is going wrong in your body, it is also a specimen whose colour, texture, and taste can help you identify the exact thing gone wrong.

That is, while a yellow or green vomit with bits of indigested food may indicate indigestion, stomach flu, or food poisoning, a clear vomit is most often the sign of gastric outlet obstruction or head injury. Similarly, while a foamy vomit may mean you have excess gas in your stomach, blood in the vomit could be a sign of slight damage to the throat or at times, indicative of more serious diseases and conditions such as peptic ulcers, amyloidosis, liver failure, or Mallory-Weiss tear.
