User:Mr. Ibrahem/Vomiting

Vomiting, also known as emesis, is the involuntary, forceful expulsion of stomach contents through the mouth or nose. It is associated with nausea and typically lasts a day or two. Complications may include dehydration, aspiration, electrolyte abnormalities, damage to teeth, and an esophageal tear. Vomiting differs from regurgitation, in that regurgitation does not involve contraction of the stomach or nausea.

Common causes include gastroenteritis and certain medications or toxins. Other causes include cannabis hyperemesis syndrome, cyclic vomiting syndrome, bowel obstruction, hepatitis, increased intracranial pressure, migraine, eating disorders, diabetic ketoacidosis, motion sickness, nausea and vomiting or pregnancy, appendicitis, and labyrinthitis. In babies causes may include reflux, volvulus, pyloric stenosis urinary tract infection, and intussusception.

Treatment includes trying to drink enough fluids. Antiemetics pay be used to improve symptoms. There is also some evidence for breathing in isopropyl alcohol. If dehydration is present, intravenous fluid may be useful. Worrisome signs include severe abdominal pain, blood in the vomit, severe headache, signs of dehydration, and green vomit. Vomiting is the reason for about 1.6% of visits to family physicians in Australia.
