Nausea is not an illness; it is a symptom of several conditions, many of which are not related to the stomach. Nausea is often indicative of an underlying condition elsewhere in the body. Travel 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 don't "agree" to what extent the body is actually moving the symptom is presented as nausea even though the stomach itself has nothing to do with the situation. Nausea is also an adverse effect of many drugs. Nausea may also be an effect of a large intake of sugary foods.
In medicine, nausea can be a problem during some chemotherapy regimens and following general anaesthesia. Nausea is also a common symptom of pregnancy. Mild nausea experienced during pregnancy can be normal, and should not be considered an immediate cause for alarm.

Treatment :
While short-term nausea and vomiting are generally harmless, they may sometimes indicate a more serious condition, such as Celiac Disease. When associated with prolonged vomiting, it may lead to dehydration and/or dangerous electrolyte imbalances.
Symptomatic treatment for nausea and vomiting may include short-term avoidance of solid food. This is usually easy as nausea is nearly always associated with loss of appetite. Dehydration may require rehydration with oral or intravenous electrolyte solutions. Oral rehydration (drinking water) is safer and simpler in most cases. If the cause is by motion sickness, sitting down in a still environment may also help.
There are several types of antiemetics (drugs to suppress nausea and vomiting), and researchers continue to look for more effective treatments. The main types used post operatively for surgical patients are ondansetron (Zofran), dexamethasone (Decadron), promethazine (Phenergan) diphenhydramine (Gravol), and in small doses droperidol. Doxylamine is the drug of choice in pregnancy-related nausea. Anecdotally, another remedy used by recovery room nurses is to place an isopropyl alcohol swab under the patient's nose while he or she breathes through the nose. This may abate the nausea until the antiemetic medication takes effect. THC, a chemical found in marijuana, when injested has been shown to reduce nausea in some users. Also available are a variety of non-invasive, mechanical devices used to suppress nausea due to motion sickness. However, these products are seldom tested in a laboratory setting.
