Sleep Apnea

Overview

Sleep apnea is a sleep disorder characterized by repeated pauses in breathing during sleep. The most common form, obstructive sleep apnea (OSA), occurs when the airway collapses or becomes blocked. Obesity is the strongest risk factor, as excess tissue around the neck and airway increases obstruction. Untreated sleep apnea contributes to cardiovascular disease, metabolic dysfunction, and reduced quality of life.

Causes

Causes include obesity, enlarged tonsils, nasal obstruction, airway anatomy, alcohol use, sedatives, and neuromuscular conditions. Central sleep apnea is less common and related to brain signaling issues.

Risk Factors

Risk factors include obesity, large neck circumference, male sex, aging, family history, smoking, alcohol use, and nasal congestion.

How Sleep Apnea Affects the Body

Repeated breathing pauses reduce oxygen levels, increase stress hormones, disrupt sleep cycles, and strain the cardiovascular system. This leads to fatigue, hypertension, insulin resistance, and increased risk of heart disease and stroke.

Complications

Complications include hypertension, atrial fibrillation, heart disease, stroke, type 2 diabetes, fatty liver disease, depression, and increased risk of accidents due to daytime sleepiness.

Symptoms & Signs

Symptoms include loud snoring, gasping during sleep, daytime fatigue, morning headaches, poor concentration, irritability, and waking up unrefreshed.

Diagnosis

Diagnosis is made through sleep studies (polysomnography or home sleep testing), oxygen monitoring, and evaluation of airway anatomy.

Differential Diagnosis

Includes insomnia, restless leg syndrome, narcolepsy, chronic fatigue, and anxiety‑related sleep disturbances.

Lifestyle Modifications

Lifestyle strategies include weight loss, avoiding alcohol before bedtime, improving sleep hygiene, treating nasal congestion, and sleeping on one’s side.

Treatment Options

Treatment includes CPAP therapy, oral appliances, weight‑loss medications, bariatric surgery, positional therapy, and surgical airway procedures when indicated. Weight loss is one of the most effective treatments for OSA.

When to See a Doctor

Seek evaluation if you snore loudly, feel excessively tired during the day, or have witnessed breathing pauses during sleep.

When to Seek Treatment

Treatment is recommended when sleep apnea is confirmed, when symptoms affect daily functioning, or when cardiovascular or metabolic risks are present.

Long-Term Outlook

Long‑term management focuses on weight control, consistent CPAP use (if prescribed), and monitoring for cardiovascular complications.

Prognosis

With proper treatment, symptoms improve dramatically, and long‑term cardiovascular and metabolic risks decrease. Weight loss can significantly reduce or resolve sleep apnea.
