Severe snoring is often caused by nasal congestion or airway narrowing. If nasal congestion is the main trigger, generic corticosteroid nasal sprays (like fluticasone) or simple saline sprays can help reduce inflammation and improve airflow. However, because the snoring is severe, it could indicate an underlying condition like obstructive sleep apnea. I highly recommend consulting a doctor or sleep specialist for a proper evaluation. They can identify the exact cause and recommend the safest, most effective treatment, which may include lifestyle adjustments, oral appliances, or breathing devices rather than just nasal sprays.
