The cause of hiccups is often attributed to a SPASM of the diaphragm, which is the muscle that separates the chest and abdominal cavities. This SPASM can be caused by a variety of things, such as eating too quickly, drinking carbonated beverages, or even excitement. The medical term for hiccups is 'SINGULTUS, ' which comes from the Latin word for 'SOB.' Hiccups can last anywhere from a few minutes to several hours, and in some cases, they can last for days or weeks. The most common treatment for hiccups is to hold one's breath for as long as possible, or to drink a glass of water quickly.
