Sleep Apnea

Sleep apnea is a common disorder that causes breathing pauses during sleep, leading to daytime drowsiness and increased health risks; a range of treatments can help manage the condition.

Overview

Sleep apnea is a disorder in which breathing stops or becomes very shallow during sleep. Pauses can last from a few seconds to several minutes and may occur 30 times or more per hour.

Types

The most common type is obstructive sleep apnea, which occurs when the airway collapses or becomes blocked during sleep. Normal breathing typically resumes with a snort or choking sound.

Symptoms

  • Loud snoring (though not everyone who snores has sleep apnea)
  • Snorting or choking sounds as breathing resumes
  • Daytime drowsiness due to interrupted sleep

Risk Factors

  • Overweight or obesity
  • Male gender
  • Family history of sleep apnea
  • Small airway anatomy
  • Children with enlarged tonsils or adenoids

Diagnosis

Doctors diagnose sleep apnea based on:

  • Medical and family histories
  • Physical examination
  • Sleep study results

Impact of Untreated Sleep Apnea

Interrupted sleep can cause daytime drowsiness, increasing the risk of:

  • Car crashes
  • Work‑related accidents
  • Other medical problems

Treatment & Management

Effective treatment options include:

  • Lifestyle changes (e.g., weight loss)
  • Mouthpieces (oral appliances)
  • Surgery
  • Breathing devices (e.g., CPAP)

Frequently Asked Questions

Snoring that is accompanied by pauses in breathing, gasping or choking sounds, or a sudden awakening with a sense of breathlessness is more suggestive of sleep apnea. Additionally, persistent daytime sleepiness, morning headaches, or difficulty concentrating are red flags that warrant a sleep study. What lifestyle changes can reduce my sleep apnea severity without using CPAP?::Weight loss, regular exercise, avoiding alcohol and sedatives before bedtime, sleeping on your side instead of your back, and using nasal strips or a positional therapy device can all lessen apnea episodes. Consistent sleep schedules and maintaining a cool, quiet bedroom environment also help. How does sleep apnea increase my risk of heart disease, and what monitoring should I have?::Sleep apnea causes intermittent hypoxia and sympathetic surges, which raise blood pressure, promote arrhythmias, and accelerate atherosclerosis. Regular monitoring of blood pressure, periodic ECGs, and possibly a Holter monitor for arrhythmia detection are advisable. Discuss with your cardiologist whether an echocardiogram or lipid panel should be added to your routine. Are there alternative treatments to CPAP for moderate sleep apnea?::Yes. Oral appliances that advance the lower jaw (mandibular advancement devices) can be effective for mild‑to‑moderate cases. Surgical options such as uvulopalatopharyngoplasty (UPPP), maxillomandibular advancement, or hypoglossal nerve stimulation may be considered if CPAP is poorly tolerated or ineffective. A sleep specialist can evaluate which alternative best fits your anatomy and severity.
