Nausea and Vomiting

Nauseas and vomiting are usually manifestation of some underlying disease that are usually non life threatening. Occasionally, it might be an indicator of underlying serious conditions like brain disease, intestinal obstruction and heart disease. Nausea is the feeling of uneasiness in the stomach whereas vomiting is the forceful emptying of the stomach content. Vomiting occurs when the muscles of stomach and esophagus contract vigorously forcing the food content up and out of mouth. Occasionally, during these contraction no food particles are ejected. It is called “retching”. Vigorous retching can lead to tear in the inner lining of the esophagus called “Mallory Weiss tear” or sometimes lead to rupture of the esophagus. Nausea and vomiting usually occur together but can occur separately. You can have nausea that does not lead to vomiting and you may have vomiting without nausea. Nausea and vomiting is triggered by stimulation of stomach and  intestine, inner ear and brain.
