Pauses in breathing during sleep refer to repeated short interruptions or reductions in airflow during sleep. This page outlines common causes, frequent signs you or others may notice, and when to seek medical assessment. For diagnosis and management, consult a healthcare professional.
Pauses in breathing during sleep include episodes where airflow either partially or completely stops. The two main types are obstructive events, caused by blockage of the upper airway, and central events, due to reduced or absent respiratory signals from the brain. Both can cause drops in blood oxygen levels and brief awakenings that fragment sleep.
Multiple factors often contribute. Common contributors include excess weight, larger neck circumference, airway anatomy differences (e.g., enlarged tonsils, narrow nasal passages), smoking, alcohol use, older age and male sex. Certain neurological or cardiovascular conditions and hormonal factors may increase risk. Often more than one factor is present.
Typical signs include loud, habitual snoring, witnessed pauses in breathing during sleep, gasping or choking episodes on awakening, morning headache, persistent daytime sleepiness and difficulty concentrating. A bed partner’s observations—such as repeated breathing interruptions—are often key to recognizing the problem.
If you have chronic loud snoring, witnessed breathing pauses, excessive daytime sleepiness or trouble concentrating, discuss these symptoms with your primary care clinician. Referrals for further evaluation are commonly made to pulmonology (respiratory medicine), ear–nose–throat (ENT) specialists or neurology. Urgent care or emergency services should be used if severe breathing difficulty, fainting, new confusion, chest pain or blue discoloration of lips or face occur.
