Nausea
  • 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.

    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

    last date of your menstrual period, as well as
    the kind of contraceptives you use, if you use
    any at all.
