Sleep apnea is a serious, potentially life-threatening condition that is far more common than generally understood and it can affect a person’s ability to safely perform normal daily activities and can affect long term health. It occurs in all age groups and both genders but it is more common in men, although it may be under-diagnosed in women. Other risk factors include middle and older age, being overweight or obese, and having a small throat or deformity in upper airway. It estimates that OSA affects 4 – 7 % of middle age and 70% of clinically obese patients. Early recognition and treatment of sleep apnea is important.
