Abstract: Continuous hiccups in the elderly are due to enlarged lungs caused by tumors, which stimulate the diaphragm and cause diaphragm spasm. If you have continuous hiccups for a long period of time, you should go to a regular hospital for examination as soon as possible. Elderly people should be especially wary of lung cancer because of their declining immunity and declining functions of various organs. Have you ever heard of someone being diagnosed with lung cancer because of hiccups? Generally, hiccups are caused by swallowing food too quickly or too fast, or eating irritating food, as well as sluggish stomach peristalsis and eating too much food, which will disappear naturally after a few minutes. However, if you have hiccups continuously for a longer period of time, you should go to a regular hospital for examination as soon as possible, especially for elderly people with reduced immunity and reduced functions of various organs, especially to prevent the occurrence of lung cancer.
