Daytime sleepiness is considered the most common symptom of sleep apnea in adults. This condition often leads to disrupted sleep patterns due to repeated interruptions in breathing during sleep, which can result in significant fatigue and excessive daytime sleepiness. This symptom is recognized as a key indicator of sleep apnea, as affected individuals may struggle to stay awake during the day, affecting their daily activities and overall quality of life.

While snoring is another frequent symptom associated with sleep apnea, it is not as universally evident since not all individuals who snore have this condition. Morning headaches can occur due to the lack of oxygen during sleep, but they are less common than daytime sleepiness. Weight loss may be beneficial for individuals with sleep apnea but is not a typical symptom experienced by those affected. Thus, daytime sleepiness stands out as the primary and most prevalent symptom related to sleep apnea in adults.
