Obstructive sleep apnea

Obstructive sleep apnea: overview

Obstructive Sleep Apnea (OSA) is a common sleep disorder characterized by repeated pauses in breathing during sleep due to partial or complete blockage of the upper airway. These pauses, called apneas, can last from a few seconds to a minute or more and occur several times per hour throughout the night. People with OSA often snore loudly and struggle to stay asleep, leading to fragmented, non-restorative sleep and excessive daytime sleepiness.

Causes of Obstructive Sleep Apnea

OSA occurs when the muscles in the upper airway relax and collapse during sleep, blocking the flow of air. This can be due to a variety of factors, including obesity, aging, and physical abnormalities in the airway such as large tonsils or a deviated septum. Alcohol and sedative use, as well as certain medical conditions such as nasal congestion, can also contribute to OSA.

Symptoms of Obstructive Sleep Apnea

Common symptoms of OSA include:

• Loud snoring
• Gasping or choking during sleep
• Repeated awakenings during the night
• Excessive daytime sleepiness
• Irritability or mood changes
• Difficulty concentrating or paying attention
• Dry mouth or sore throat upon waking
• Headaches
• Chest pain or discomfort

Diagnosis and Treatment of Obstructive Sleep Apnea

Diagnosis of OSA typically involves a thorough evaluation of sleep patterns, medical history, and lifestyle factors. A sleep study, such as polysomnography (a test that records brain activity, eye movements, and other physiological signals during sleep), may be performed to confirm the presence of OSA and determine its severity.

Treatment for OSA may include lifestyle changes, such as weight loss and avoiding alcohol and sedatives, as well as medical therapy, such as continuous positive airway pressure (CPAP) therapy, which uses a mask to deliver air pressure to keep the airway open during sleep. In some cases, dental devices or surgery may be recommended.

In severe cases of OSA, surgery may be recommended to remove excess tissue from the airway or reposition the jaw and tongue to improve air flow. In some cases, a combination of lifestyle changes and medical therapy may be recommended.

It is important to seek treatment for OSA, as untreated OSA can lead to a number of serious health problems, including high blood pressure, heart disease, stroke, and decreased quality of life. People with symptoms of OSA should speak with their healthcare provider to discuss treatment options.

Why this matters for local patients

• Sleep symptoms such as snoring, witnessed pauses in breathing, daytime sleepiness, fatigue, insomnia and restless sleep can affect work, driving, mood, metabolism and long-term health.
• Many patients in NYC, New Jersey, Connecticut and Philadelphia prefer convenient evaluation, home sleep study options and fast follow-up rather than waiting months for care.
• W8MD combines sleep medicine with obesity medicine, helping patients address both breathing during sleep and weight-related metabolic risk.
