Nausea is that "queasy" sensation you get in your stomach that makes you feel as if you are about to vomit. It is a common condition that can be caused by a variety of circumstances and conditions.

Feelings of nausea can be caused by constipation, digestive disorders, food poisoning, gallstones, head injury, migraine headaches, side effects of medication, vertigo and viral infections. Often, circumstances, such as over eating and eating too quickly can cause an upset stomach. Other forms of nausea is morning sickness (which often occurs in women during their early months of pregnancy) and motion sickness (often seen in both children and adults).

The most common cause of nausea is gastroenteritis, also referred to as intestinal flu. Technically this illness is not a flu because it is not caused by the influenza virus. Gastroenteritis is normally caused by a viral infection and is over within forty eight hours.

A change in diet may help. Bananas are good. Avoid coffee and juices, especially citrus drinks. Whole-grain cereals, soups and steamed vegetables are good if they can be eaten. Drinking plenty of fluids - clear liquids, including distilled or bottled water - and munching occasionally on soda crackers may help.
