Nausea is a general term which is describing a queasy stomach with or without the feeling that you are about to vomit. Almost every single person experiences nausea at some point of his life which is making it one of the most common problems that is discovered in the medicine. This is not a disease. It is a symptom of many different disorders. In the most cases the queasy feeling lasts no more than minutes to a few hours and usually it goes away on its own within 24 hours.

Symptoms of Nausea

This condition is difficult for many people to describe. It is a very, but not painful, feeling that you felt in the back of your throat, your chest or your upper abdomen. This feeling is associated with an urge to vomit or with distaste for food. When your body prepares to vomit, then these following sequences can happen:

  • The lower portion of stomach contracts
  • The windpipe (larynx) closes
  • The abdominal muscles and diaphragm contract
  • The muscular ring between the esophagus and stomach (esophageal sphincter) relaxes

When some individual vomits, then the stomach contents are expelled through the mouth and esophagus. As a result of these body actions, when you suffer from nausea you experience retching (which is repeated rhythmic contractions of abdominal and respiratory muscles which occur without our control). You may vomit or you may not. In some cases nausea is accompanied by profuse sweating.

Causes for nausea

Nausea can be caused by problems in any of three parts of our bodies which are including:

  • Balance centers in your inner ear: Nausea can be related to vertigo. Vertigo is a dizzy sensation of falling, moving or spinning when you are not moving. The most common conditions which are causing nausea are: sensitivity to position change (benign positional vertigo), certain brain or nerve tumors, viral infections of the inner ear (labyrinthitis) and motion sickness (triggered by repeated movements in different directions inside a car, boat, train, plane or amusement ride).

The most common abdominal causes are including gallbladder problems; inflammation of the kidney; appendix or pelvic organs; intestinal lining; irritation of the stomach, GERD (gastroesophageal reflux); a blocked or stretched intestine or stomach; pancreas (pancreatitis) and inflammation of the liver (hepatitis).
