Key Difference – Sleep Apnea vs Snoring

Thekey differencebetween Sleep Apnea and snoring is thatSleep apnea is a sleep disorder characterized by pauses in breathing or instances of irregular breathing during sleep caused by an obstruction in the transient upper airwaywhilesnoring is just the vibration of respiratory structures and the resulting sound due to partial obstruction to the air passage during breathing at sleep.However, snoring can be a symptom of sleep apnea.

What is Sleep Apnea?

Apnea is defined as each pause in breathing which can last for several seconds to several minutes, and it may recur at least 5 times in an hour. Hypopnea is defined as abnormally shallow breathing. When breathing is paused, carbon dioxide accumulates in the bloodstream. Chemoreceptors in the blood stream detect the highcarbon dioxidelevels which try to wake the person from the sleep and breathe in air. Breathing will restore oxygen levels, and the person will fall asleep again. This continues as cycles leading to irregular breathing pattern. Sleep apnea is diagnosed with a sleep test called a polysomnogram (sleep study).

Obstructive sleep apnea is recognized as a problem by others witnessing the individual during episodes or as the results of the complications occurred due to sleep apnea as the person is not aware of it. Symptoms may be present for years without identification due to this factor.

Symptoms include excessive daytime sleepiness, impaired alertness, excessive snoring, daytime fatigue, a slower reaction time, vision problems. Obstructive sleep apnea can increase the risk of driving accidents and work-related accidents. Rarely, even death could occur in untreated cases due to lack of oxygen to the brain.

Risk factors include male gender, overweight, over the age of 40; a large neck size (greater than 16–17 inches), enlargedtonsils,enlarged tongue, small jaw bone, gastro-esophageal reflux,allergies, sinus problems, family history of sleep apnea, or deviated nasal septum causing obstructions. Also, alcohol, sedatives, and tranquilizers can promote sleep apnea by relaxing the throat muscles. These factors should be addressed when treating a patient with obstructive sleep apnea.

Behavioral therapy, offering continuous positive airway pressure by an external device or surgical procedures (sleep surgery) in selected cases are used to treat sleep apnea.Difference Between Sleep Apnea and Snoring-sleep apena
