There are a large number of causes, including large meals, alcohol, or hot and spicy foods. Hiccups may also start and stop for no obvious reason. There is no sure way to stop hiccups. You can try - Breathing into a paper bag - Drinking or sipping a glass of cold water - Holding your breath Hiccups aren't usually serious.
