Sleep Study & Sleep Apnoea –Related Disorders
Sleep Study & Sleep Apnoea evaluation plays a crucial role in diagnosing sleep-related breathing disorders that silently affect overall health. Many people ignore symptoms like loud snoring, daytime sleepiness, or restless sleep—often assuming they are harmless. In reality, these may point to sleep apnoea, a serious but treatable condition.
At SRC Hospital, Dr. Puneet Aggarwal, Pulmonologist & Respiratory Specialist, offers accurate sleep studies and personalised treatment plans to help patients sleep better and live healthier.
What is a Sleep Study (Polysomnography)?
A sleep study, medically known as polysomnography, is a painless overnight test that records how your body behaves while you sleep. It monitors:
Breathing patterns
Oxygen levels
Heart rate
Brain activity
Body movements
Snoring episodes
This test helps identify breathing interruptions and other abnormalities that occur during sleep.
What Is Sleep Apnoea?
Sleep apnoea is a condition where breathing repeatedly stops and starts during sleep. These pauses can last a few seconds to over a minute and may happen dozens of times each night—often without the patient realizing it.
Common Types of Sleep Apnoea
Obstructive Sleep Apnoea (OSA) – airway blockage during sleep
Central Sleep Apnoea – brain fails to send proper breathing signals
Complex Sleep Apnoea – combination of both
For additional patient-friendly medical information, you may also refer to the Mayo Clinic’s overview of sleep apnoea.
Symptoms You Should Not Ignore
You may need a sleep study and sleep apnoea evaluation if you experience:
Loud, chronic snoring
Excessive daytime sleepiness
Morning headaches
Poor concentration or memory
Waking up gasping or choking
Uncontrolled blood pressure
Fatigue despite adequate sleep
Why Early Diagnosis Matters
Untreated sleep apnoea can lead to serious health problems such as:
High blood pressure
Heart disease and stroke
Diabetes
Depression and anxiety
Increased accident risk due to daytime drowsiness
Early diagnosis through a sleep study helps prevent these complications.
Sleep apnoea can also worsen existing respiratory conditions such as asthma, especially when left untreated.

The test is safe, non-invasive, and comfortable.
Treatment Options for Sleep Apnoea

CPAP/BiPAP therapy
Lifestyle modifications (weight loss, sleep position)
Oral appliances
Management of nasal or airway conditions
Treatment of associated lung or heart disorders
Dr. Puneet Aggarwal provides individualised treatment, not one-size-fits-all solutions.

Overweight individuals
Patients with diabetes or hypertension
People with unexplained fatigue
Those with disturbed sleep patterns
If sleep is not refreshing, it’s a signal worth checking.
