Why does low blood glucose go undetected at night?

Why does low blood glucose go undetected at night?

• When a low blood glucose occurs counterregulatory hormones (such as glucagon and epinephrine) are released to raise blood glucose. 
• The release of these hormones provides the initial symptoms (shaking, sweating, rapid heart beat, etc.) that an individual may feel when their blood glucose is low. Such symptoms will likely trigger an individual to treat a low blood glucose.
• 
  
• However, while asleep such symptoms/signals are suppressed and/or go unnoticed.
• 
  
• There is also evidence that release of counterregulatory hormones are suppressed to some extent during sleep.
