A common medical complaint, nausea has many causes. It does not usually indicate a serious problem, but the Mayo Clinic advises seeking emergency attention if you also have chest pain, severe pain or cramping, blurred vision, fainting, confusion, clammy skin, high fever and stiff neck or fecal material or odor in vomit.
Viral Illness
Viral gastroenteritis can cause nausea, as well as stomach cramps and diarrhea. There is no cure except to wait for it to pass. Frequent hand washing during flu season may help you to avoid it.
Overdose
If you drink too much alcohol, ingest illicit drugs or take too much of any toxic substance, you may develop nausea.
Chemotherapy
Not everyone undergoing chemotherapy experiences nausea. Some people are more susceptible to this side effect than others. Your doctor can prescribe medications to prevent it.
Migraines
Nausea often accompanies migraine headaches, either at the onset or later. Your doctor can prescribe medication for nausea that accompanies a migraine.
Motion Sickness
Riding in a car or on a ship, plane or train makes many people nauseous. You may also experience chills and dizziness. Over-the-counter and prescription medications may help.
