What is Insomnia?

Insomnia is defined as difficulty in falling or staying asleep. The brain regulates our circadian rhythm by a sleep and wake cycle. When one is on, the other is turned off. Insomnia can result from a disturbance occurring in any one part of this cycle and could be acute or chronic in origin. Acute insomnia lasts from days to weeks and commonly occurs due to an emotional stress, loss of a loved one, a job loss, a life changing event, jet lag, mild illness or external factors like change in temperature, noise etc.

Chronic insomnia usually ranges from weeks to months and even years and is seen in patients of depression, mental disorders, long standing illness with pain and discomfort or anything that gives rise to chronic stress-physical or mental.

  • Frequent waking up at night from deep sleep
  • Un-refreshed feeling in the morning
  • Sleepiness during the day

Diagnosis and Treatment of Insomnia

In case you are experiencing sleep troubles, it is a good idea to see your doctor and narrate the symptoms in detail so that the exact type and cause of the insomnia can be identified and accordingly treated. The diagnosis is done mainly on the basis of history, physical examination and sleep record kept for at least a week.

Conditions like sleep apnea are confirmed with the help of a detailed sleep study. Patients with sleep apnea have a history of waking up suddenly in the middle of the night. This occurs because their airway gets obstructed involuntarily leading to a drop in the oxygen levels making them wake up with a start gasping for breath. People with a short neck, snoring habits and underlying lung pathology are seen to be suffering from sleep apnea syndrome.

Acute insomnia is not serious and can be corrected when the underlying physical or emotional stress is eradicated. One should avoid taking over the counter sleeping pills for such transient sleep troubles.

Chronic insomnia due to an underlying medical condition needs a systematic approach and the disease needs to be treated first. Example: depression is treated with anti-depressants. Underlying asthma or nasal blockage is treated with nasal sprays or decongestants.
