UNAWARENESS

WHAT IS HYPOGLYCEMIA UNAWARENESS?

What is Hypoglycemia Unawareness?

Hypoglycemia often happens once blood glucose levels drop below 70 mg/dl and known symptoms alert us to indicate our body is crashing. The hypoglycemia unawareness definition is when a person’s blood glucose levels fall below this level but they do not feel or sense the symptoms of hypoglycemia.

The sympathoadrenal response, which is the responses in the brain that prompt known symptoms like; sweating, shaking, disorientation—is interrupted and hindered.The brain no longer sends out signals to the body to bring about the symptoms of hypoglycemia,3 so the person does not recognize the warning signs.2 As with hypoglycemia, the body does not release hormones as it normally would in order to combat the dramatic drop of glucose levels.

With unawareness, the person will crash without warning and the result could mean severe hypoglycemia or very serious symptoms.

Severe hypoglycemia happens when blood glucose levels drop so low that a person cannot treat themselves without assistance from another person—due to disorientation, confusion, or unconsciousness. This could mean a family member, friend, stranger or emergency responder encourages the person to drink a juice, eat something, or if the person is unconscious, inject them with glucagon.5 Serious symptoms may include; loss of consciousness, seizure,4 coma, or in rare cases, death.

If a person is disoriented or becomes unconscious, they could injure themselves or others. A severe episode could cause someone to fall down stairs, hit their head, or endanger others, as well as themselves, by having a car accident while driving. These are all very dangerous possibilities which could be fatal. Experiencing seizures or unconsciousness because of severe hypoglycemia can cause brain damage since the brain is being deprived of glucose, the fuel that it depends on to function.6

What is Hypoglycemia Unawareness?

Hypoglycemia unawareness may happen more often in people who have repeatedly experienced low blood glucose levels, have had diabetes for an extended period or who tightly control their diabetes. This can desensitize a person from detecting or noticing early warning signs of an oncoming hypoglycemic crash.

While asleep, it may be more difficult for people with hypoglycemia unawareness to wake up if they experience hypoglycemia.1  A continuous glucose monitor or CGM, is a device that monitors blood glucose levels during the day and nighttime hours and is a solution for people who are at risk or already have hypoglycemia unawareness. CGMs will alert you with an alarm if blood glucose levels fall too low.7 People who have this condition should check blood glucose levels often, notably before driving.8

Managing hypoglycemia so glucose levels remain balanced and episodes do not occur for several weeks or months may bring back some sensitivity to warning symptoms.

A plan of action could be too;

  • Aim for a higher blood glucose target
  • Work on counting carbohydrates with more accuracy
  • Do not overcorrect or buildup insulin doses
  • Check blood glucose levels more often and change insulin doses
  • Look into education programs on blood glucose awareness training
  • Learn about continuous glucose monitors, (CGM)
  • Think about pursuing a service dog trained to recognize low blood glucose5

In an emergency when a person is unconscious or not able to swallow, administering glucagon is ideal. Talk with your physician about options for managing this condition and about a prescription for Glucagon or GlucaGen. Educate family and friends about glucagon and how to use it if you choose to use this product.(Check out my review of HealthTap, a service where you can speak with a doctor directly.)

  1. You’re so right, hypoglycemia could be very serious if not detected or treated, My daughter in law is diabetic and hypoglycemic, and my son has had to take her to the hospital a few times because the warning signs were so subtle that she wasn’t even noticing them anymore. You have a very insightful and informative website and I’m glad I came across it, Thank you.

    1. Wow, I bet it’s difficult for her at times, being diabetic and having to deal with her sugars going too high or too low. It can be so easy to forget to eat when we need to or stay disciplined in checking glucose levels. Unawareness can be pretty scary. I’m glad your son was there and could get her help!
      I’m glad you found the info on my site helpful. Thanks for stopping by!

  2. Hi Angela! I enjoyed your website. It was very informative and educational. I learned a lot about being hypoglycemic and the importance of trusting your body and educating yourself. I applaud you for taking your health issues into your own hands to learn what you could. Many other people may have this and not be aware of it as well. Keep up the good job of educating us about this disease.

    1. Thank you, Rhonda, for visiting my site. I’m glad you found it informative and helpful! Knowing about unawareness can be helpful to anyone. Someone who has this condition could be out and about and suddenly need help from the people around them.
      Thanks again!
