Why do I get hiccups out of nowhere?

Some causes of hiccups include: Eating too quickly and swallowing air along with foods. Eating too much (fatty or spicy foods, in particular) or drinking too much (carbonated beverages or alcohol) can distend the stomach and cause irritation of the diaphragm, which can cause hiccups.

Is it normal to hiccup randomly?

Hiccups are often caused by many everyday situations, including distention of the stomach (which can be the result of overeating), swallowing air, or drinking carbonated beverages. They usually go away on their own, but episodes that last longer than 48 hours could be a sign of certain medical problems.
