Hiccups: Understanding the Cause & Why There's No 'Purpose'

Teleological explanations are explanations that refer to the purpose or function of something. There is no teleological explanation for hiccups. Hiccups are involuntary spasms of the diaphragm that can be caused by a variety of factors, such as eating too quickly, drinking carbonated beverages, or being nervous. They are usually harmless and go away on their own.
