Conditions that cause dry heaves and stomach pain include alcohol abuse; bacterial and viral infections; allergic reactions or intolerance to specific foods; and motion sickness, explains The University of Texas at Austin University Health Services. However, dry heaves and nausea can also result from more serious problems such as meningitis and head trauma.
Other health problems that can cause nausea and vomiting, including dry heaves, are pregnancy, stress, migraines, inner ear problems and drainage from sinus infections, states The University of Texas at Austin University Health Services. Certain conditions have easy treatments such as taking anti-motion sickness drugs for motion sickness-induced nausea and dry heaves. Only eat plain crackers and drink clear liquids; avoid caffeinated beverages and acidic drinks.
If dry heaves, stomach pain and vomiting occur directly after prescription medication use or a recent head injury, seek emergency medical treatment, advises The University of Texas at Austin University Health Services. If a person experiences fever, back pain or dizziness, he needs to be watched closely in case symptoms worsen, and then seek medical care. Nausea and dry heaves accompanied by dizziness, dry mouth, weakness and confusion can be a sign of dehydration. If the symptoms accompany pain or pressure in the chest, radiating pain to the jaw and arm, sweating and irregular heartbeat, this can be a sign of a heart attack and requires emergency care.
