Individuals who are burping a lot and feeling sick may be struggling with indigestion, according to NHS Direct Wales. Additional accompanying symptoms include feeling full or bloated and the regurgitation of food or fluid into the gullet. Indigestion is a common condition that affects everyone although symptoms are typically temporary and only happen occasionally.
Indigestion is classified as a burning sensation behind the breastbone or pain or discomfort in the upper abdomen. It happens when stomach acid comes into contact with the lining and membrane of esophageal tissues, which are rather sensitive. Indigestion is generally triggered due to diet although it has also been linked to smoking, drinking, certain medications, pregnancy and stress.
