For anybody who lives with diabetes, the potential of hypoglycemia, or low blood glucose (sugar) ranges, is usually a fixed concern. An additional layer of complexity is added when individuals with diabetes can’t detect that their blood sugars are dropping, a situation often called hypoglycemia unawareness.
It’s each extra frequent — and probably extra harmful — than many individuals assume.
This text will clarify what that you must learn about hypoglycemia unawareness, how you can 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 under regular ranges. That is typically a results of an imbalance between elements that elevate blood glucose, reminiscent of meals consumption, and people who decrease it, reminiscent of insulin or different glucose-lowering medicines.
Whereas everybody with diabetes typically experiences low blood sugar ranges, individuals who use insulin usually expertise episodes of hypoglycemia extra steadily.
What is taken into account low blood sugar will differ by the individual primarily based on well being historical past, well being targets, and what blood sugar ranges you and your well being care supplier decide is finest in your goal vary.
The U.S. Facilities for Illness Management and Prevention (CDC) describes low blood sugar ranges as something underneath 70 mg/dL (3.9 mmol/L) in individuals with diabetes.
Severely low blood glucose ranges are thought-about to be something underneath 54 mg/dL (3.0 mmol/L). This can require speedy therapy with both fast-acting glucose or glucagon (if the individual can’t chew or swallow).

What are the signs of hypoglycemia?
Widespread signs of hypoglycemia embrace:
- Shakiness
- Dizziness
- Fatigue/lethargy
- Unhappiness
- Confusion
- Sweating
- Fast coronary heart charge
- Nervousness
- Starvation
- Bother concentrating
- Irritability
Signs of extreme low blood sugar embrace:
- Slurred speech
- Confused considering
- Lack of consciousness
- Seizures
- Coma
- In uncommon situations, loss of life
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 rather more frequent than many individuals assume 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 called sulfonylureas, each of which might trigger low blood sugar.
Taking insulin will increase the chance of experiencing low blood sugar ranges, and frequent low blood sugar ranges enhance the chance of creating hypoglycemia unawareness.
Hypoglycemia unawareness considerably will increase the chance 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 know-how, this will result in hypoglycemia turning into extreme. With out quick therapy, it has the potential to lead to acute issues reminiscent of lack of consciousness, seizures, and in excessive instances, life-threatening outcomes.
Moreover, recurring episodes of extreme hypoglycemia can contribute to long-term issues, reminiscent of 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 chance elements for hypoglycemia unawareness?
There are a number of identified threat elements for creating hypoglycemia unawareness, together with the next:
- Lengthy-term use of insulin. Analysis signifies that the chance of creating hypoglycemia unawareness will increase with the length of insulin therapy. 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 current and/or recurrent low blood sugar occasions (reminiscent of lows at evening, when it’s possible you’ll 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. Nonetheless, a number of key elements are thought to contribute to its growth:
- Frequent episodes of hypoglycemia can result in a situation often called 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 issues, can paradoxically enhance the chance of hypoglycemia unawareness. It is because aiming for decrease blood sugar targets could result in extra frequent episodes of hypoglycemia, thereby rising 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 purpose for very tight blood sugar management, are at an elevated threat of creating this situation.
Can medicines trigger hypoglycemia unawareness?
Sure medicines, together with beta-blockers, can masks the signs of hypoglycemia, reminiscent of coronary heart palpitations and tremors, making it more durable to detect an oncoming low. It is 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 despair, may masks low signs, though their impression is much less clear.
Moreover, alcohol can intervene with blood sugar regulation and masks signs of lows. And this substance might be doubly problematic as a result of it could additionally enhance your probability of going low.
Are there issues from hypoglycemia unawareness?
Having hypoglycemia unawareness considerably will increase the chance of each short- and long-term issues.
With out the everyday early warning indicators of low blood sugar, the scenario is extra prone to be extreme by the point it’s acknowledged and therapy is tried. These extreme lows can impair essential features, making it tough to carry out on a regular basis actions reminiscent of driving, studying, and dealing, and might cloud judgment and cognition.
In case you don’t deal with your low blood sugar rapidly sufficient, it might even lead to extra severe issues, reminiscent of lack of consciousness, seizures, coma, and mind damage. Over time, recurring extreme hypoglycemia can even contribute to cardiovascular issues and cognitive decline.
How will you stop and deal with hypoglycemia unawareness?
Speak to your healthcare supplier for those who discover that you’re 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 degree can differ 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 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.
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 right away deal with lows can also be beneficial, 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) could present an extra 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 might 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 techniques use values out of your CGM and run them by way of 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 the US, a number of AID techniques 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.
Chances are you’ll not at all times 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.
Work intently along with your physician to tailor these approaches to your particular wants and circumstances.
