    Major Signs and Symptoms
                
One of the most common signs of obstructive sleep apnea is loud and chronic (ongoing) snoring. Pauses may occur in the snoring. Choking or gasping may follow the pauses.
                
The snoring usually is loudest when you sleep on your back; it might be less noisy when you turn on your side.
