and the amount of oxygen in the blood drops, often to very low. This alerts the brain, causing a brief arousal (awakening) and breathing resumes. These stoppages of breathing can occur repeatedly, causing multiple sleep disruptions throughout the night and result in excessive daytime sleepiness and impaired daytime function.
Untreated sleep apnea puts a person at risk for cardiovascular disease, headaches, memory loss and depression. It is a serious disorder that is easily treated.

As we age, there is an increased incidence of medical problems, which are often chronic. In general, people with poor health or chronic medical conditions have more sleep problems. For example, hypertension is associated with both snoring and OSA and heart failure - which affects approximately 5 million Americans - is linked with OSA. In addition, menopause and its accompanying hot flashes, changes in breathing, and decreasing hormone levels can lead to many restless nights.
Gastroesophageal reflux disease (GERD) is another common cause of sleep problems. The pain also makes it difficult to sleep. Medical conditions such as diabetes mellitus, renal failure, respiratory diseases such as asthma, and immune disorders are all associated with sleep problems and disorders.
