Obstructive Sleep Apnea

Obstructive Sleep Apnea

Obstructive Sleep Apnea (OSA) is a common sleep disorder characterized by repeated interruptions in breathing during sleep. These interruptions, known as apneas, occur when the muscles in the throat relax excessively, causing a temporary blockage or obstruction of the upper airway. Here's a brief overview of OSA:

Causes

OSA typically occurs when the muscles at the back of the throat become too relaxed during sleep, leading to a partial or complete blockage of the airway. This often happens due to anatomical factors (e.g., narrow airway, large tonsils) and lifestyle factors (e.g., obesity, smoking) that contribute to airway narrowing.

Symptoms:

The most common symptoms of OSA include loud and chronic snoring, pauses in breathing or choking sounds during sleep, excessive daytime sleepiness, difficulty concentrating, morning headaches, and irritability. OSA can also contribute to other health problems such as high blood pressure, heart disease, and diabetes.

Diagnosis:

Diagnosis is typically based on a combination of factors, including a thorough medical history, a sleep evaluation conducted in a sleep laboratory (polysomnography), and home sleep tests. These tests monitor various parameters during sleep, such as oxygen levels, heart rate, and airflow, to determine the severity of the condition.

Treatment:

Treatment for OSA aims to keep the airway open during sleep and improve oxygen flow. Common treatment options include:

• Continuous Positive Airway Pressure (CPAP): This involves wearing a mask over the nose and/or mouth during sleep, which delivers a continuous stream of air pressure to keep the airway open.
• Bi-level Positive Airway Pressure (BiPAP): Similar to CPAP, but with variable air pressure levels for inhalation and exhalation. It's often used when CPAP alone is not effective.
• Oral Appliances: Dentists can provide customized oral devices that reposition the jaw and tongue to help keep the airway open.
• Surgery: Surgical options are considered in cases where other treatments are ineffective or impractical. Procedures may involve removing excess tissue, repositioning the jaw, or altering the structure of the airway.
