What cause hiccups ?
Hiccups occur when the diaphragm muscle spasms involuntarily, paired with sudden vocal cord closure creating the characteristic hic sound. Common triggers include eating too fast, consuming carbonated drinks, swallowing air, or eating spicy foods. Most hiccups resolve within minutes but persistent cases lasting over 48 hours may indicate medical conditions like gastroesophageal reflux disease, central nervous system disorders, or metabolic problems. The reflex involves nerves including the phrenic and vagus nerves that can become irritated by various factors from diet to underlying health conditions.
