Why do people choke while sleeping?

People can choke while sleeping due to several reasons, primarily related to airway obstruction. This can occur if the tongue falls back into the throat, blocking the airway, especially in individuals with sleep apnea or those who sleep on their backs. Additionally, conditions such as gastroesophageal reflux disease (GERD) can cause stomach contents to enter the throat, triggering a choking response. Other factors may include obesity, alcohol consumption, or certain medications that relax the throat muscles.
