Causes of nausea or vomiting.
There are many and varied causes of vomiting. It is a common manifestation of organic and functional disorders. It may be caused by acute or chronic indigestion, nervous disorders and reflex irritation. Acute systemic infections with fever, especially in young children are frequently accompanied by vomiting and often by severe diarrhea. The ailment may be caused by a throat infection, tonsillitis, if the mucosal lining of the enlarged tonsils is inflamed and anything swallowed even saliva, may irritate the nerve ending, causing nausea or actual vomiting.

Hepatitis is another cause, where, depending on the extent and seriousness of the cause, there may be slight nausea or actual persistent vomiting. Certain drugs or prescribed medications, chemotherapy, systemic infections, poisoning, travel sickness, emotional upsets or stress, are some of the other causes. Simple causes, which are not life-threatening, such as morning sickness during early pregnancy, or the sight of blood, or seeing a reptile, may be simple and easy to treat. But persistent, unprovoked vomiting needs specific investigation. Whatever the cause, it needs to be discovered and treated. Meanwhile, there is the urgent need to settle that queasy feeling and to prevent dehydration by replacing vital fluids and essential electrolytes lost.
