'''Nausea''' ([[Latin]] ''nausea'', from [[Greek language|Greek]] {{Polytonic|ναυσίη}}, ''nausiē'', "seasickness"), is the sensation of unease and discomfort in the upper [[stomach]] and [[head]] with an urge to [[vomit]]. An attack of nausea is known as a '''qualm'''. Nausea which affects the stomach is sometimes called '''wamble'''.

Nausea is also an [[Adverse effect (medicine)|adverse effect]] of many drugs, [[opiate]]s in particular, and may also be a side-effect of a large intake of sugary foods.

Nausea is not a sickness, but rather a symptom of several conditions, many of which are unrelated to the stomach. Nausea is often indicative of an underlying condition elsewhere in the body. [[Motion sickness]], which is due to confusion between perceived movement and actual movement, is an example: the sense of equilibrium lies in the ear and works together with eyesight. When these two "disagree" about the extent to which the body is actually moving, the symptom is presented as nausea, although the stomach itself has nothing to do with the situation. The stomach's involvement comes from the brain's conclusion that one of the senses is hallucinating due to poison ingestion; the brain then induces vomiting to clear the supposed toxin{{Citation needed|date=May 2009}}.

In medicine, nausea can be a problem during some [[chemotherapy]] regimens and following [[general anaesthesia]]. Nausea is also a common symptom of [[pregnancy]], in which it is called "[[morning sickness]]". Mild nausea experienced during pregnancy can be normal, and should not be considered an immediate cause for alarm.

Nausea (Latin nausea, from Greek ναυσίη, nausiē, "seasickness"), is the sensation of unease and discomfort in the upper stomach and head with an urge to vomit. An attack of nausea is known as a qualm. Nausea which affects the stomach is sometimes called wamble.

CausesEdit

Nausea is also an adverse effect of many drugs, opiates in particular, and may also be a side-effect of a large intake of sugary foods.

Nausea is not a sickness, but rather a symptom of several conditions, many of which are unrelated to the stomach. Nausea is often indicative of an underlying condition elsewhere in the body. Motion sickness, which is due to confusion between perceived movement and actual movement, is an example: the sense of equilibrium lies in the ear and works together with eyesight. When these two "disagree" about the extent to which the body is actually moving, the symptom is presented as nausea, although the stomach itself has nothing to do with the situation. The stomach's involvement comes from the brain's conclusion that one of the senses is hallucinating due to poison ingestion; the brain then induces vomiting to clear the supposed toxin[citation needed].

In medicine, nausea can be a problem during some chemotherapy regimens and following general anaesthesia. Nausea is also a common symptom of pregnancy, in which it is called "morning sickness". Mild nausea experienced during pregnancy can be normal, and should not be considered an immediate cause for alarm.

Causes of nausea include, but are not limited to:

TreatmentEdit

While short-term nausea and vomiting are generally harmless, they may sometimes indicate a more serious condition, such as coeliac disease. When associated with prolonged vomiting, it may lead to dehydration and/or dangerous electrolyte imbalances.

Symptomatic treatment for nausea and vomiting may include small portions of solid food. This is usually not easy, as nausea is nearly always associated with loss of appetite. If the patient is dehydrated, rehydration with oral or intravenous electrolyte solutions may be required. Ingesting crushed ice has also proven effective. [citation needed] If the cause of the nausea is motion sickness, sitting down in a still environment may also help.

There are several types of antiemetics, and researchers continue to look for more effective treatments. The main types used post-operatively for surgical patients are ondansetron, dexamethasone, promethazine, dimenhydrinate and (in small doses) droperidol. Doxylamine is the drug of choice in pregnancy-related nausea. When ingested or inhaled, marijuana has been shown to reduce nausea in the majority of users.[1] The antidepressant Mirtazapine has anti-emetic effects as well. Also available are a variety of non-invasive (but often untested) mechanical devices for suppressing nausea induced by motion sickness.

The spices ginger and peppermint have been used for centuries as traditional remedies for nausea, and recent research has validated these remedies.[2] Also, citron fruit was once widely considered to relieve nausea.[3]

Bismuth is another common remedy, and is contained in several over the counter stomach medications, notably Pepto-Bismol.
