7 Causes of Hiccups And 12 Ways To Relieve Them

4. Temperature Changes In Your Esophagus

Sudden changes in the temperature of your esophagus can cause hiccups. Things that irritate your esophagus can do this too. It is possible that this is related to the stimulation of the nerves that make your diaphragm contract, causing hiccups. Because the vagus nerve and phrenic nerve are located close to your esophagus, the food that you swallow can stimulate them. Some foods that could cause irritation include very hot food, spicy food, acidic food, very cold liquids, and alcohol.
