Sleep-disordered breathing, also known as sleep apnea, is a serious sleep disorder that affects millions of people worldwide. It is characterized by repeated pauses in breathing during sleep, resulting in oxygen deprivation in the body. This condition can have serious consequences for both physical and mental health if left untreated. Sleep-disordered breathing can be divided into three types: obstructive, central, and mixed. Obstructive sleep-disordered breathing is the most common form and occurs when the airways are partially or completely blocked by the soft tissues in the throat. Central sleep-disordered breathing is caused by the brain failing to send the correct signals to the muscles responsible for breathing. Symptoms can vary from person to person but often include loud snoring, repeated awakenings during the night, shortness of breath, morning headaches, and excessive daytime sleepiness. A doctor can diagnose the condition through a sleep study, where the patient’s sleep and breathing are monitored to identify interruptions. One of the most effective treatments for obstructive sleep-disordered breathing is continuous positive airway pressure (CPAP), a machine that delivers a constant flow of air through a mask worn over the nose or mouth to keep the airways open. Lifestyle changes such as weight loss, avoiding alcohol and sedatives before bedtime, and maintaining a regular sleep schedule can also help reduce symptoms. In some cases, surgery may be necessary to remove physical blockages in the airways. Early diagnosis and treatment are essential. If you experience symptoms such as loud snoring, repeated awakenings, or excessive daytime sleepiness, consult your doctor for evaluation.
