Gastroenteritis and food poisoning are the most common underlying causes of sudden vomiting and usually clear up without treatment in a couple of days. Vomiting can sometimes be a symptom of something serious. Recurrent vomiting or vomiting that has lasted more than 2 days should always be investigated by your doctor.
Vomiting alone (without diarrhea) should stop within about 24 hours. If it lasts over 24 hours, you must think about more serious causes. Examples are appendicitis, a kidney infection, diabetes and head injury.
Drink clear or ice-cold drinks. Eat light, bland foods (such as saltine crackers or plain bread). Avoid fried, greasy, or sweet foods. Eat slowly and eat smaller, more frequent meals.
Make an appointment with your doctor if: Vomiting lasts more than two days for adults, 24 hours for children under age 2 or 12 hours for infants. You've had bouts of nausea and vomiting for longer than one month. You've experienced unexplained weight loss along with nausea and vomiting.
Food allergies. Infections of the stomach or bowels, such as the "stomach flu" or food poisoning. Leaking of stomach contents (food or liquid) upward (also called gastroesophageal reflux or GERD) Medicines or medical treatments, such as cancer chemotherapy or radiation treatment.
Usually, vomiting is harmless, but it can be a sign of a more serious illness. Some examples of serious conditions that may result in nausea or vomiting include concussions, meningitis (infection of the membrane linings of the brain), intestinal blockage, appendicitis, and brain tumors. Another concern is dehydration.

In many cases, throwing up is a protective reflex to rid your body of viruses, bacteria, or parasites in your digestive system. “If you were to eat something that was spoiled or poisoned, your body would get a signal that something was wrong,” says Bruno Chumpitazi, MD, of Texas Children's Hospital.
