Medical News Today explains that a hiccup, also known as synchronous diaphragmatic flutter or singultus, refers to a sudden, involuntary diaphragm contraction that occurs simultaneously with the contraction of the larynx and complete closure of the glottis, the middle part of the larynx where vocal cords are found. Hiccups often occur rhythmically, with a relatively constant interval between every hiccup.
Most experts agree that hiccups are usually triggered by minor stomach upsets, reports Medical News Today. Experts are not certain about the mechanisms that cause hiccups, although studies reveal that certain conditions and illnesses increase a person's risk of developing hiccups. People often experience a hiccup when hot food irritates the phrenic nerve, which is found near the esophagus. Gas in the stomach that presses against the diaphragm also tends to cause hiccups. Sudden temperature changes, consumption of dizzy drinks, eating spicy foods and eating dry breads are some other common causes. Certain medications, such as anesthesia, opiates and benzodiazepines, are also known to cause hiccups. Many people also report having hiccups after drinking alcoholic beverages.Learn more about Human Anatomy
