For anybody who lives with diabetes, the potential of hypoglycemia, or low blood glucose (sugar) ranges, is usually a fixed concern.

It’s each extra widespread — and doubtlessly extra harmful — than many individuals suppose.
This text will clarify what you might want to find out about hypoglycemia unawareness, deal with it, and steps you’ll be able to take to assist stop it.
What’s hypoglycemia?
Hypoglycemia, generally known as low blood sugar, happens when the focus of glucose within the bloodstream falls beneath regular ranges. That is usually a results of an imbalance between components that increase blood glucose, akin to meals consumption, and people who decrease it, akin to insulin or different glucose-lowering medicines.

What are the signs of hypoglycemia?
Frequent signs of hypoglycemia embrace:
- Shakiness
- Dizziness
- Fatigue/lethargy
- Disappointment
- Confusion
- Sweating
- Speedy coronary heart fee
- Nervousness

If an individual is unable to chew and/or swallow, glucagon administration is unavailable or ineffective, promptly name 911.When severely low blood sugar is left untreated, it may be deadly.

What’s hypoglycemia unawareness?
Hypoglycemia unawareness is a situation through which somebody doesn’t get the standard bodily warning indicators their blood sugar ranges are going low.
It’s far more widespread than many individuals suppose and is estimated to have an effect on about 40 p.c of individuals with sort 1 diabetes. It additionally impacts 10 to fifteen p.c of individuals with sort 2 diabetes who use insulin or a category of medicines often 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 creating hypoglycemia unawareness.
Hypoglycemia unawareness considerably will increase the danger related to low blood sugar episodes by impairing an individual’s means to acknowledge and reply to the early warning indicators of hypoglycemia.
As a result of lack of expertise, this may result in hypoglycemia changing into extreme. With out quick remedy, it has the potential to lead to acute problems akin to lack of consciousness, seizures, and in excessive instances, life-threatening outcomes.
Moreover, recurring episodes of extreme hypoglycemia can contribute to long-term problems, akin to 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 identified danger components for creating hypoglycemia unawareness, together with the next:
- Lengthy-term use of insulin. Analysis signifies that the danger of creating hypoglycemia unawareness will increase with the period of insulin remedy. For instance, in a single research, 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 current and/or recurrent low blood sugar occasions (akin to lows at evening, when chances are you’ll not be capable to detect or deal with the low).
- Superior age.
What causes hypoglycemia unawareness?
The precise causes of hypoglycemia unawareness will not be completely understood. Nonetheless, a number of key components are thought to contribute to its improvement:
- Frequent episodes of hypoglycemia can result in a situation often 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’s because aiming for decrease blood sugar targets could result in extra frequent episodes of hypoglycemia, thereby growing the probability of HAAF.
Not everybody who takes insulin will expertise hypoglycemia unawareness, however the probability 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 creating this situation.
Can medicines trigger hypoglycemia unawareness?
Sure medicines, together with beta-blockers, can masks the signs of hypoglycemia, akin to coronary heart palpitations and tremors, making it tougher to detect an oncoming low. It’s because they block the motion of adrenaline.
Though these medicines deal with circumstances like angina (a sort 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 affect is much less clear.
Moreover, alcohol can intervene with blood sugar regulation and masks signs of lows. And this substance could be doubly problematic as a result of it could additionally enhance your probability 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 standard 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. These extreme lows can impair crucial capabilities, making it tough to carry out on a regular basis actions akin to driving, studying, and dealing, and may cloud judgment and cognition.
If you happen to don’t deal with your low blood sugar rapidly sufficient, it might even lead to extra severe problems, akin to lack of consciousness, seizures, coma, and mind harm. Over time, recurring extreme hypoglycemia can even contribute to cardiovascular problems and cognitive decline.

Speak to your healthcare supplier in case you discover that you’re now not detecting signs of low blood sugar.
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 grow to be extra delicate to your blood sugar ranges falling.
Your healthcare supplier could recommend decreasing your every day insulin dosage, barely growing your goal blood sugar vary, or modifying your bodily exercise routine to forestall low blood sugar ranges within the first place.
You may additionally be capable to catch low blood sugars sooner by checking your blood sugar ranges extra steadily or sporting a steady glucose monitor (CGM). Carrying fast-acting carbohydrates with you to instantly deal with lows can also be advisable, 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 feature requires consideration of the coaching and dedication concerned.
Moreover, some individuals have discovered that switching to slower-acting insulins could 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 stop extreme lows.
For individuals who have entry to the know-how, utilizing an automatic insulin supply (AID) system can considerably assist in stopping hypoglycemia.
These methods 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 lowered or paused as blood sugar ranges lower, serving to to forestall hypoglycemia.
In the USA, a number of AID methods 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.
You might not all the time be capable to reverse hypoglycemia unawareness, however you’ll be able to enhance your sensitivity, largely by avoiding low blood sugar ranges for some time.
