What’s hypoglycemia unawareness?
Hypoglycemia unawareness is a situation through which somebody doesn’t get the same old bodily warning indicators their blood sugar ranges are going low.
It’s far more frequent than many individuals suppose and is estimated to have an effect on about 40 p.c of individuals with kind 1 diabetes. It additionally impacts 10 to fifteen p.c of individuals with kind 2 diabetes who use insulin or a category of medicines generally known as sulfonylureas, each of which may trigger low blood sugar.
Taking insulin will increase the danger of experiencing low blood sugar ranges, and frequent low blood sugar ranges enhance the danger of growing hypoglycemia unawareness.
Hypoglycemia unawareness considerably will increase the danger related to low blood sugar episodes by impairing an individual’s potential to acknowledge and reply to the early warning indicators of hypoglycemia.
As a result of lack of information, this will result in hypoglycemia changing into extreme. With out quick remedy, it has the potential to end in acute problems resembling lack of consciousness, seizures, and in excessive instances, life-threatening outcomes.
Moreover, recurring episodes of extreme hypoglycemia can contribute to long-term problems, resembling cardiovascular and cognitive points.
The danger and incidence of experiencing severely low blood sugar ranges enhance dramatically for individuals who have hypoglycemia unawareness.
What are the danger components for hypoglycemia unawareness?
There are a number of recognized danger components for growing hypoglycemia unawareness, together with the next:
- Lengthy-term use of insulin. Analysis signifies that the danger of growing hypoglycemia unawareness will increase with the length of insulin remedy. For instance, in a single examine, about half of the individuals who had used insulin for over 20 years developed hypoglycemia unawareness, whereas solely about 20 p.c of those that had been on insulin for fewer than 10 years skilled it.
- A historical past of latest and/or recurrent low blood sugar occasions (resembling lows at evening, when you could not be capable to detect or deal with the low).
- Superior age.
What causes hypoglycemia unawareness?
The precise causes of hypoglycemia unawareness aren’t completely understood. Nevertheless, a number of key components are thought to contribute to its growth:
- Frequent episodes of hypoglycemia can result in a situation generally known as hypoglycemia-associated autonomic failure (HAAF), the place the physique’s regular alert system to low blood sugar turns into much less delicate. Basically, the physique and mind begin to adapt to decrease glucose ranges, diminishing the notion of hypoglycemic signs.
- Tight blood sugar management, whereas essential for managing diabetes and stopping long-term problems, can paradoxically enhance the danger of hypoglycemia unawareness. It is because aiming for decrease blood sugar targets might result in extra frequent episodes of hypoglycemia, thereby rising the chance of HAAF.
Not everybody who takes insulin will expertise hypoglycemia unawareness, however the chance will increase with the size of time somebody has had diabetes. Those that have lived with diabetes for an prolonged interval, and particularly those that persistently goal for very tight blood sugar management, are at an elevated danger of growing this situation.
Can drugs trigger hypoglycemia unawareness?
Sure drugs, together with beta-blockers, can masks the signs of hypoglycemia, resembling coronary heart palpitations and tremors, making it tougher to detect an oncoming low. It is because they block the motion of adrenaline.
Though these drugs deal with circumstances like angina (a kind of chest ache), coronary heart failure, and hypertension, this impact on adrenaline could make it harder to detect the early indicators of hypoglycemia.
Selective serotonin reuptake inhibitors (SSRIs), used to deal with despair, may additionally masks low signs, though their influence is much less clear.
Moreover, alcohol can intrude with blood sugar regulation and masks signs of lows. And this substance may be doubly problematic as a result of it might probably additionally enhance your chance of going low.
Are there problems from hypoglycemia unawareness?
Having hypoglycemia unawareness considerably will increase the danger of each short- and long-term problems.
With out the everyday early warning indicators of low blood sugar, the state of affairs is extra prone to be extreme by the point it’s acknowledged and remedy is tried.

Most individuals with diabetes ought to be capable to really feel low blood sugar ranges once they attain 70 mg/dL (3.9 mmol/L), though this stage can fluctuate for individuals with a historical past of frequent lows.
If an individual with diabetes has hypoglycemia unawareness, formal packages exist to enhance blood glucose consciousness. Moreover, your well being care supplier can talk about potential methods to turn out to be extra delicate to your blood sugar ranges falling.
Your healthcare supplier might counsel decreasing your each day insulin dosage, barely rising your goal blood sugar vary, or modifying your bodily exercise routine to forestall low blood sugar ranges within the first place.

Carrying fast-acting carbohydrates with you to right away deal with lows can also be really helpful, as is having a glucagon equipment readily available within the occasion of a extreme low (glucagon is a hormone that helps elevate glucose ranges).
For some, a diabetes alert canine (DAD) might present an extra layer of safety by alerting to low blood sugars. Nevertheless, this selection requires consideration of the coaching and dedication concerned.
Moreover, some individuals have discovered that switching to slower-acting insulins may be useful in the event that they expertise persistent hypoglycemia unawareness. These insulins have a slower launch time, offering a extra predictable blood-sugar-lowering impact, and so might assist stop extreme lows.
For many who have entry to the expertise, utilizing an automatic insulin supply (AID) system can considerably assist in stopping hypoglycemia.
These programs use values out of your CGM and run them via an algorithm to find out how a lot insulin to ship by way of a pump. Insulin is lowered or paused as blood sugar ranges lower, serving to to forestall hypoglycemia.
In america, a number of AID programs can be found, together with the Medtronic MiniMed 770G System, Medtronic MiniMed 780G System, Tandem Diabetes Care t:slim X2 with Management-IQ Know-how, and Omnipod 5 Automated Insulin Supply System.
Chances are you’ll not at all times be capable to reverse hypoglycemia unawareness, however you possibly can enhance your sensitivity, principally by avoiding low blood sugar ranges for some time.
