Overview
Nausea (Latin: Nausea, Greek: Template:Polytonic, "sea-sickness") is the subjective feeling of a need to vomit. 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 anesthesia. 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. Vomiting (also throwing up or emesis) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose resulting from contractions of gut and thoracoabdominal wall musculature. Vomiting may result from many causes, ranging from gastritis or poisoning to brain tumors, or elevated intracranial pressure (ICP). The feeling that one is about to vomit is called nausea. It usually precedes but does not always lead to vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting, and in severe cases where dehydration develops, intravenous fluid may need to be administered to replace fluid volume. The medical branch investigating vomiting, emetics, and antiemetics is called emetology.
Diagnosis
Electrocardiogram
ECG is done to rule out an inferior MI or arrhythmia.
