Sleep Disorders

Approximately 42 million Americans have Sleep Apnea – as prevalent as diabetes and asthma combined. 25% of middle aged men and 9% of middle aged women suffer from Obstructive Sleep Apnea (OSA). The disorder takes its name from the Greek word “Apne” which means without breath. People with OSA frequently stop breathing repeatedly during their sleep.

Untreated OSA can result in

    • Hypertension
    • Cardiovascular diseases, arrhythmias, heart attack, and heart failure
    • Strokes
    • Type II Diabetes
    • Mood disorders (anxiety and/or depression)
    • Increased morbidity and mortality
    • Obesity

Dr. Karupaiah is Board certified and specialized  in the diagnosis and treatment of Sleep Disorders.

To diagnose the condition, we offer a highly specialized test called a Nocturnal Polysomnogram which evaluates a patient’s sleep patterns, respiratory events, and cardiac rhythms during an overnight stay at our office supervised by registered sleep technologists in our on-site Sleep Lab. Insomnia, excessive daytime sleepiness, narcolepsy and restless leg syndrome are common disorders which we also diagnose and treat.

After a diagnosis of obstructive sleep apnea, the patient is scheduled for a CPAP titration study. CPAP therapy begins by identifying the appropriate pressure for your CPAP. It also provides the opportunity to try different CPAP masks. At the culmination of the CPAP titration study, the ideal pressure and mask settings can be determined.

We also provide Home sleep study testing to diagnose Obstructive sleep apnea. Detailed instructions will be provided to the patient at the office regarding the proper way to use the equipment at home.

Internal Medicine

Internal Medicine is the branch and specialty of medicine concerning the diagnosis and non-surgical treatment of diseases in adults. Internists are sometimes referred to as the “doctor’s doctor” because they are often called upon to act as consultants to other physicians to help solve puzzling diagnostic problems. Doctors of internal medicine treat the whole person.
