What You Need to Know about OSA (Obstructive Sleep Apnea)

OSA is a sleep disorder where relaxed throat muscles block the airway, causing interrupted breathing during sleep. Symptoms include loud snoring, gasping for air, and daytime fatigue.

Diagnosis involves a sleep study to monitor breathing patterns. Treatment options range from lifestyle changes to CPAP therapy to improve sleep quality and reduce health risks like hypertension and heart disease.

What is Obstructive Sleep Apnea(OSA)?

Obstructive sleep apnea(OSA) is the most common sleep disorder characterized by repetitive episodes of nocturnal breathing cessation due to upper airway collapse. It is a complex disease with numerous clinical manifestations.

Obstructive Sleep Apnea Symptoms:

Here the obstructive sleep apnea symptoms include:

Heavy snoring
Excessive daytime sleepiness
Witnessed apnea and gasping.

There are subgroups of individuals who do not complain about these typical symptoms but instead present with other atypical symptoms, such as:

Morning headache
Bruxism
Nocturia
Chronic cough
Dysphagia

Because of these symptoms, OSA often remains undiagnosed. OSA can coexist with or be triggered by other intrinsic sleep disorders, such as

Chronic insomnia disorder
Nightmares
Restless leg syndrome
Periodic limb movement disorder

Symptoms of Sleep Disorders

General symptoms of sleep disorders are:

Difficulty falling asleep during the night
Constant tiredness during the daytime
Unusual breathing patterns
Lack of focus
Depression
Limb movements while asleep
Unexplained anxiousness or irritable behaviour
A sudden weight gain
Poor performance at work or school

Obstructive Sleep Apnea Diagnosis

The diagnosis of obstructive sleep apnea (OSA) typically includes the following procedures:

Medical History: Your physician will inquire about your symptoms, sleep habits, and medical background, including any risk factors like obesity or a family history of sleep apnea.
Physical Examination: A physical assessment may be performed to look for physical indicators such as obesity, a large neck circumference, or narrow airways.
Sleep Study (Polysomnography): This is the main test utilized to diagnose sleep apnea. It involves monitoring various bodily functions during sleep, such as breathing patterns, oxygen levels, heart rate, and brain activity.
Home Sleep Apnea Testing: In certain instances, a simplified version of a sleep study can be conducted at home to diagnose OSA.
Other Tests: Additional tests may be suggested to evaluate the severity of sleep apnea or to pinpoint underlying conditions contributing to sleep disruptions.

The diagnosis of OSA is essential for determining the appropriate treatment to enhance sleep quality and reduce associated health risks.

Obstructive Sleep Apnea(OSA) Treatment:

OSA is treated by conservative management like weight reduction, avoiding alcohol, and sleeping pills for mild cases.
For moderate and severe cases, mechanical therapy like continuous positive airway pressure(CPAP) bi-level positive airway pressure(BiPAP) and
Other surgical options are available, like somnoplasty, tonsillectomy, uvulo palate pharyngoplasty, nasal surgery, and mandibular/ maxillary advancement surgery.

OSA can result in various health conditions, including hypertension, heart failure, arrhythmias,diabetes mellitus,obesity, cognitive impairment, mood changes, and heart attacks.

Frequently Asked Questions

OSA is a sleep disorder where breathing repeatedly stops and starts during sleep due to blocked airflow in the throat.

OSA is often caused by the relaxation of throat muscles, leading to a blocked airway. Factors like obesity, large tonsils, or a small jaw can contribute.

Yes, untreated OSA can lead to serious health problems like high blood pressure, heart disease, stroke, and poor quality of life.

Yes, children can have OSA, often due to enlarged tonsils or adenoids. Symptoms may include snoring, restless sleep, and trouble concentrating.

While there is no cure for OSA, treatments such as CPAP machines, mouth appliances, and surgery can help control the condition.

Untreated OSA can lead to major problems such as heart disease, diabetes, and an increased risk of accidents caused by daytime lethargy.

Risks are minimal but can include skin irritation from the mask, dry mouth, or discomfort. Proper adjustment and maintenance can minimize these risks.

Some people find relief from positional therapy (sleeping on their side), elevating the head of the bed, or using nasal strips to improve airflow.
