What’s hypoglycemia unawareness?
Hypoglycemia unawareness is a situation by which somebody doesn’t get the same old bodily warning indicators their blood sugar ranges are going low.
It’s way 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 referred to as sulfonylureas, each of which might 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 capability to acknowledge and reply to the early warning indicators of hypoglycemia.
This may result in hypoglycemia turning into extreme, which, with out quick remedy, has the potential to end in acute problems akin to lack of consciousness, seizures, and in excessive circumstances, life-threatening outcomes.
Moreover, recurring episodes of extreme hypoglycemia can contribute to long-term problems, akin to cardiovascular and cognitive points.
The chance and incidence of experiencing severely low blood sugar ranges enhance dramatically for individuals who have hypoglycemia unawareness.
What are the danger elements for hypoglycemia unawareness?
There are a number of recognized threat elements for growing hypoglycemia unawareness, together with the next:
- Being handled with insulin
- Having diabetes for a very long time (one research discovered that half of people that had used insulin for over twenty years developed hypoglycemia unawareness, whereas solely about 20 p.c of those that have been on insulin for fewer than ten years skilled it)
- A historical past of latest and/or recurrent low blood sugar occasions (akin to lows at evening, when you might not have the ability to detect or deal with the low)
- Superior age
What causes hypoglycemia unawareness?
The precise causes of hypoglycemia unawareness usually are not solely understood. Nonetheless, a number of key elements are thought to contribute to its growth:
- Frequent episodes of hypoglycemia can result in a situation referred to as hypoglycemia-associated autonomic failure (HAAF), the place the physique’s regular alert system to low blood sugar turns into much less delicate. Primarily, 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’s because aiming for decrease blood sugar targets could result in extra frequent episodes of hypoglycemia, thereby growing the chance of HAAF.
- The usage of steady glucose monitoring (CGM) programs makes tight diabetes management simpler by offering real-time suggestions on blood glucose ranges. Whereas CGMs can alert customers to impending lows, the general threat of hypoglycemia unawareness should be influenced by the aggressive pursuit of tight glucose targets.
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 intention for very tight blood sugar management, are at an elevated threat of growing this situation.
Can medicines trigger hypoglycemia unawareness?

Though these medicines deal with situations like angina (a kind of chest ache), coronary heart failure, and hypertension, this impact on adrenaline could make it tougher to detect the early indicators of hypoglycemia.
Selective serotonin reuptake inhibitors (SSRIs), used to deal with melancholy, may additionally masks low signs, though their influence is much less clear.

Carrying fast-acting carbohydrates with you to right away deal with lows can be really helpful, as is having a glucagon package available within the occasion of a extreme low (glucagon is a hormone that helps increase glucose ranges).
For some, a diabetes alert canine (DAD) could present a further layer of safety by alerting to low blood sugars. Nonetheless, this selection requires consideration of the coaching and dedication concerned.
Moreover, some folks have discovered that switching to slower-acting insulins, like R, N, or NPH, will 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 could assist forestall 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 by an algorithm to find out how a lot insulin to ship by way of a pump. Insulin is diminished 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 Expertise, and Omnipod 5 Automated Insulin Supply System.
It’s possible you’ll not at all times have the ability to reverse hypoglycemia unawareness, however you possibly can enhance your sensitivity, largely by avoiding low blood sugar ranges for some time.
