Acidity or heartburn are cues that
normal digestion has been interrupted for one or more reasons. If
stomach acid enters the oesophagus, for example, you may feel heartburn.
Swallowing too much air while eating or drinking can induce a distended
stomach and cause excessive belching. Stomach infections or inflammation
can bring on gastritis. Acidity is an irritation of the oesophagus that
is caused by stomach acid. If it is not treated on time, it leads to a
broken inflamed portion of the lining or mucosal membrane of the stomach
known as ulcer.
Symptoms are abdominal pain felt either at the front or
in the back which may be more severe before a meal, nausea
and bloating. Some drugs, particularly
aspirin, anti- inflammatory drugs and corticosteroids encourage the
formation of an ulcer.
