Risk factors

Risk factors that may contribute to snoring include:

• Being a man. Men are more likely to snore or have sleep apnea than are women.
• Being overweight. People who are overweight or obese are more likely to snore or have obstructive sleep apnea.
• Having a narrow airway. Some people may have a long soft palate, or large tonsils or adenoids, which can narrow the airway and cause snoring.
• Drinking alcohol. Alcohol relaxes your throat muscles, increasing the risk of snoring.
• Having nasal problems. If you have a structural defect in your airway, such as a deviated septum, or your nose is chronically congested, your risk of snoring is greater.
• Having a family history of snoring or obstructive sleep apnea. Heredity is a potential risk factor for OSA.
