Heartburn

A burning sensation accompanied by burning pain in the chest area, behind the breastbone, and in the throat. At times, the burning sensation may extend to the neck and reach the mouth.
The symptoms usually appear after eating, but may also occur at night. Lying down or bending forward may worsen the symptoms.
Excess weight, pregnancy, a high-fat diet, nighttime eating, and smoking increase the risk of developing Heartburn.
In most cases, lifestyle changes will alleviate the unpleasant sensation.
