Vomiting: Problems
built 254 days ago
Fresh blood in the vomit is termed hematemesis ("blood vomiting"). Altered blood bears resemblance to coffee grounds (as the iron in the blood is oxidized), and, when this matter is identified, the term "coffee ground vomiting" is used. Bile can enter the vomit during subsequent heaves due to duodenal contraction if the vomiting is severe. Fecal vomiting is often a consequence of intestinal obstruction or a gastro-colic fistula, and is treated as a warning sign of this potentially serious problem ("signum mali ominis"); such vomiting is sometimes called "miserere."

The main problem with the profuse vomiting is, it cannot be stopped by taking oral medicines as even medicines are expelled out of the stomach the moment they are taken. The body reflex of vomiting does not allow the medicine to stay and so to work and therefore, ultimately the sufferer is treated with intravenous injections containing anti-vomiting properties.
