Vomiting (or emesis) is the forceful expulsion of the contents of one's stomach through the mouth. Although it probably evolved as a mechanism for expelling ingested poisons, vomiting may result from many causes not related to poisoning, ranging from gastritis to brain tumors, or elevated intracranial pressure (ICP). The feeling that one is about to vomit is called nausea. It usually, but not necessarily, precedes vomiting, but it does not always lead to vomiting. Antiemetics are somet ...

Vertigo is the sensation of spinning while the body is stationary. With the eyes shut there will be a sensation that the body is in movement; if the eyes are open the surrounding will appear to move past the field of vision. The effects may be slight; may cause nausea; or, if severe, may give rise to difficulty with standing and walking. Vertigo is usually associated with a problem in the inner ear balance mechanisms (vestibular system), with a problem in the brain, or with the nerve connections between these two organs.

Cannabidiol, also known as CBD, is a non-psychoactive cannabinoid found in the hemp plant Cannabis sativa. CBD is not psychoactive, and appears to reduce the euphoric effect of THC, which is an isomer of cannabidiol. It may decrease the rate of THC clearance from the body, perhaps by interfering with the metabolism of THC in the liver. Medically, it appears to relieve convulsion, inflammation, anxiety, and nausea. CBD has a greater affinity for the CB2 receptor than for the CB1 receptor. It is percei ...

The introduction of the 5HT3 receptor antagonist, ondansetron, in the early 1990s was a significant breakthrough. Despite the many studies, however, the evidence base to support rational antiemetic treatment remains patchy. Recent research has led to better understanding of some older drugs and has demonstrated that combinations of drugs are often useful. While the efficacy of droperidol is now clear, metoclopramide, a popular antiemetic for decades, has been found to have no worthwhile efficacy. Some older dr ...

Vomiting - Nausea inducement in groups. It is quite common that when one person vomits, others nearby will become nauseated, particularly when smelling the vomit of others, often to the point of vomiting themselves. It is believed that this is an evolved trait among primates. Many primates in the wild will tend to browse for food in small groups. Should one member of the party react adversely to some ingested food it may be advantageous (in a survival sense) for other members of the party to also vomit. This tend ...
