Nothing is as disruptive to leading a normal, productive life as the inability to get good, restful sleep. Almost everyone experiences an occasional sleepless night, but if you find it impossible to sleep night after night, consider seeking medical help.

At the Sleep Lab, your sleep patterns are tracked overnight. Our sleep team records valuable information that will lead to a proper diagnosis and the best course of action for you.

If you have trouble sleeping, you may have a sleep disorder called sleep apnea. You are not alone! At least 40 million Americans suffer from sleep disorders, and 12 million of those have sleep apnea.

Symptoms include:

  • Excessive daytime sleepiness and fatigue
  • Snoring loudly with periods of no breathing
  • Falling asleep while driving or doing other daytime activities
  • Waking with a dry throat
  • Experiencing morning headaches
  • Showing irritability and mood changes
  • Sleeping restlessly

Sleep apnea is a serious condition

A lot of people think their sleep problem is just an annoyance, but people with sleep disorders are at risk for developing other conditions such as high blood pressure, diabetes or heart problems. People who suffer with poor sleep often feel drowsy and fall asleep during the day, affecting their daily activities and creating dangers such as falling asleep at the wheel. And sleep apnea, a disorder in which there are repeated pauses in breathing during sleep, can prevent the body from getting enough oxygen, can cause excessive daytime fatigue and moodiness and can lead to stroke or heart failure if left untreated.

Our medical director

Our sleep studies are conducted under the direction of Naeem Rana, MD, who is board-certified in both pulmonology and sleep medicine. Dr. Rana interprets the sleep studies and provides detailed reports to primary or referring physicians who then order treatments for their patients based on sleep study results.

Dr. Rana is also accepting patients to treat conditions including snoring, sleep apnea, hypersomnia (such as narcolepsy) and parasomnias (such as sleep walking). Dr. Rana has extensive training and experience and a passion for helping people with sleep disorders improve their quality of life through better sleep. He will work closely with your primary care provider to help you with your treatment plan and achieve the best outcomes.
