Untreated Obstructive Sleep Apnea (OSA) can have significant health consequences that extend beyond sleep disturbances. The recurring disruptions in breathing during sleep contribute to a range of medical and physiological complications. One of the most concerning outcomes is the increased risk of cardiovascular problems. The repeated drops in blood oxygen levels and the strain on the cardiovascular system can lead to hypertension (high blood pressure), heart arrhythmias, and even an elevated risk of heart attack or stroke. Moreover, OSA has been linked to metabolic disturbances, including insulin resistance and type 2 diabetes. The disrupted sleep patterns associated with OSA can interfere with the body’s ability to regulate glucose metabolism, potentially exacerbating insulin resistance and increasing the likelihood of diabetes development. Untreated OSA also impacts cognitive function and daytime performance. Excessive daytime sleepiness resulting from poor sleep quality can impair concentration, memory, and decision-making skills. This not only affects daily activities but also poses a safety risk, particularly when driving or operating heavy machinery.
