Nausea can be caused by many different health conditions that range in severity. One of the most common, and benign, causes is stomach upset, or gas, which can be corrected quickly by an over-the-counter medicine that contains Simethicone. However, if the nausea persists and/or results in vomiting, consult your physician, as this may indicate a more serious health condition.
