Severe headache and nausea may indicate overindulgence in alcohol.
However, experts say these could be symptoms of something more dangerous to your health after just one or two drinks.
After drinking heavily, you can expect a hangover, writes the New York Post .
These symptoms should be of concern after drinking a small amount of alcohol.
Nausea and headache after one drink indicate alcohol intolerance, says allergist-immunologist Jeffrey Factor.
He also added that alcohol intolerance is more common than alcohol allergy.
The doctor stressed that symptoms of alcohol intolerance include flushing, hives, nasal congestion, nausea, vomiting and low blood pressure.
Experts emphasize that alcohol intolerance occurs because the body cannot effectively break down toxins.
To prevent the above reactions, doctors advise stopping drinking alcohol.
