Which symptom is commonly associated with obstructive sleep apnea?

• A. Daytime sleepiness
• B. Night sweats
• C. Weight gain
• D. Insomnia

Answer: (A)

Obstructive sleep apnea causes the airway to repeatedly collapse during sleep, leading to brief pauses in breathing and frequent awakenings. This fragmentation of sleep leaves you feeling unusually tired and sleepy during the day, which is the most common and recognizable symptom of the condition. Night sweats aren’t typical for OSA and would point to other issues; weight gain is a risk factor that can contribute to developing OSA but isn’t a direct symptom you experience during sleep; insomnia refers to trouble with falling or staying asleep, which can occur with many conditions but doesn’t capture the characteristic daytime fatigue driven by repeated breathing interruptions in OSA.
