Nausea can be referred to as the uneasiness which one feels in the stomach, just before one feels the urge to vomit.

This condition can be short-lived, from a couple of seconds to a couple of minutes, or can be prolonged. If it is prolonged, it is incapacitating for the person and is a signal of a more serious condition festering underneath.

The uneasiness during nausea is generally felt in the upper abdomen, chest and back of the throat.

Why does nausea occur?

Nausea that is followed by vomiting is not a disease in itself, but the symptom of an underlying disorder, which can be physical or psychological. Nausea can also be a side effect of some specific conditions, for example, chemical changes within the body. Mostly, the timing of nausea can reveal the cause.

Nausea can happen due to disorders such as:

  • heart attack
  • glaucoma
  • migraine
  • ulcers

  • overeating
  • food poisoning

Depending on your medical history, and recent symptoms the doctor may advise you to undergo some tests such as blood tests, neurological tests, and also pregnancy tests if there are chances that you could be pregnant. The doctor will also check your blood pressure and do an abdominal examination if required.

For the proper diagnosis to be done, you need to mention to the doctor any emotional distress you may be experiencing, or any abnormal habits that you may have suddenly developed such as binge eating.

If you are a woman of childbearing age and are sexually active, you need to tell the doctor the last date of your menstrual period, as well as the kind of contraceptives you use, if you use any at all.
