What is the Difference Between Sleep Apnea and Snoring?

🆚 Go to Comparative Table 🆚

The main difference between sleep apnea and snoring lies in the severity and consequences of the two conditions. Here are the key differences:

  • Snoring: Snoring is the hoarse or harsh sound that occurs when air flows past relaxed tissues in the mouth. It is caused by the vibrations in the airway during sleep. Snoring can be a symptom of a sleep disorder called obstructive sleep apnea (OSA). Not all snorers have OSA, but it is a key symptom to consider.
  • Sleep Apnea: Sleep apnea is a condition where the upper passages of the airway close off, interrupting breathing and depriving the individual of oxygen until they wake and start breathing again. OSA, the most common form of sleep apnea, is characterized by pauses in breathing during sleep, lasting from a few seconds to minutes, followed by choking, snorting, or gasping. Sleep apnea is a more serious condition than snoring, as it can lead to various health issues, such as poor sleep quality, daytime fatigue, weight gain, memory loss, and a higher risk of high blood pressure, heart attacks, strokes, and other chronic conditions.

It is important to note that snoring and OSA are on a spectrum, and over time, a person's snoring may evolve into OSA. The only definite way to tell the difference between snoring and snoring caused by sleep apnea is through medical testing, such as a sleep study or a home sleep apnea test. These tests monitor breathing patterns, oxygen levels, heart rhythms, and other bodily systems while the individual sleeps, allowing doctors to determine whether the person has sleep apnea.

Comparative Table: Sleep Apnea vs Snoring

Here is a table highlighting the differences between sleep apnea and snoring:

Feature Snoring Sleep Apnea
Definition Snoring results when your throat relaxes and the tissues of your throat vibrate. Sleep apnea occurs when your airway is obstructed or blocked completely, causing gaps in your breathing.
Oxygen Levels Unlike sleep apnea, snoring does not cause unsafe drops in your blood oxygen levels. Sleep apnea causes drops in blood oxygen levels due to interrupted breathing.
Causes Snoring can occur temporarily or due to factors like frequent colds, alcohol abuse, weight fluctuation, and age. The causes of sleep apnea include obesity, age, gender, genetics, smoking, alcohol consumption, and nasal congestion.
Symptoms Snoring is characterized by loud, frequent, and sometimes accompanied by gasping, choking, or pauses in breathing. In sleep apnea, breathing stops or slows for greater than 10 seconds at a time at various points during sleep, causing fragmented sleep and daytime sleepiness.
Relationship Not all snorers have sleep apnea, but snoring that is loud, frequent, and accompanied by gasping, choking, or pauses in breathing may be a sign of sleep apnea. Snoring is common in people who have sleep apnea, but not everyone with sleep apnea snores.

It is essential to consult a doctor if you suspect sleep apnea, as they can recommend the appropriate testing and treatment options.
