Usually, a thorough medical history hints the underlying cause of sleeping disorders. Physical examination, along with, a few investigations can help to accurately diagnose the underlying physical disease. These investigations include:

  • Blood investigations like complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), prostate-specific antigen (PSA) (in males), blood sugar evaluation etc. are used to diagnose the underlying physical ailments.
  • EEG (electroencephalography) helps in evaluating the electrical activity of the brain and assess brain waves.
  • Polysomnography (sleep study) helps in evaluating body activity, brain waves, and oxygen levels during sleep.

Treating the underlying disease helps in alleviating the symptoms. Certain medications and modalities also help in relieving sleep disorders. These treatment options include:

  • Medications – Certain medications like sleeping pills, anti-anxiety tablets, anti-allergy drugs etc. can be sleep inducing.
  • Counselling – Counselling, along with, medication can help, especially if sleep disorders are due to psychological stress or psychiatric illness.

Reducing water intake before bedtime can curb the urge to urinate during the night. Avoiding stimulants like caffeine and alcohol in the evening or night time can also be useful.
