As people grow older, their spleen and stomach and intestinal functions decline, and some seemingly “normal” reactions after a meal may be a sign of disease. Hiccups after a meal can be a sign of liver disease. Many people think that burping after a meal is a sign that they are eating more comfortably, but in fact burping is a short sound made by the involuntary intermittent contraction of the diaphragm, causing the air to be suddenly sucked into the respiratory tract. Occasional hiccups are harmless, but persistent hiccups can produce discomfort in the chest. If the hiccups are serious and do not disappear easily on their own, beware of tumors that cause enlargement of the liver and spasm of the diaphragm due to stimulation of the diaphragm, which requires prompt medical attention to identify the cause so as not to delay treatment.
