Obstructive sleep apnea (OSA) is a common sleep disorder in which the airway becomes partially or completely blocked during sleep, leading to repeated breathing interruptions. These episodes can last from a few seconds to minutes and can occur multiple times throughout the night. Causes: OSA occurs when the muscles in the throat relax excessively during sleep, causing a temporary blockage of the airway. Factors that contribute to OSA include: Obesity: Excess body weight, especially around the neck, can compress the airway. Large tonsils or adenoids: These can obstruct the airway, particularly in children. Nasal congestion: Chronic nasal obstruction can make breathing more difficult at night. Aging: Muscle tone in the throat decreases with age, increasing the likelihood of airway collapse. Genetics: Family history or anatomical features, such as a thick neck or a narrow airway, can increase risk. Symptoms: Loud snoring (often the most noticeable sign) Gasping for air during sleep E...
