What Causes Nausea?
Nauseais a nonspecific symptom, meaning it can be related to many different conditions, both digestive and non-digestive.
It could also result for no apparent reason.
For some people, nausea is triggered by acidic foods, like tomatoes or oranges.
Drinks could also cause nausea.

Amigraineis a jot down of headache that can become disabling.
It may cause symptoms that include throbbing head pain along with nausea and sensitivity to sound and light.
The nausea may come on even before the head pain does.

This is called exercise-induced gastrointestinal syndrome (EIGS).

One trick often used at hospitals and emergency departments to relieve nausea is smelling isopropyl alcohol.
