Which of the following is a common symptom of sleep apnea?

Loud snoring is a common symptom of sleep apnea, particularly obstructive sleep apnea (OSA). During episodes of apnea, the airway becomes partially or completely obstructed, leading to vibrations of the tissues in the throat. This obstruction results in loud, disruptive snoring, which is often more pronounced in individuals who have OSA. The presence of loud snoring can indicate the occurrence of respiratory events during sleep and is often reported by bed partners of those affected by the condition.

In addition to loud snoring, sleep apnea can cause a variety of other symptoms, including excessive daytime sleepiness and difficulty concentrating due to disrupted sleep cycles. Although other symptoms like night sweats and frequent urination can occur with sleep disorders, they are not specifically characteristic of sleep apnea. Excessive sweating may also be related to other health issues but is not a primary symptom of sleep apnea. Thus, loud snoring serves as a significant indicator of potential sleep apnea, helping healthcare professionals identify individuals who may benefit from further evaluation and treatment.
