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 elements that increase blood glucose, similar to meals consumption, and people who decrease it, similar to insulin or different glucose-lowering drugs.
Whereas everybody with diabetes generally experiences low blood sugar ranges, individuals who use insulin usually expertise episodes of hypoglycemia extra regularly.
What is taken into account low blood sugar will range by the particular person based mostly on well being historical past, well being targets, and what blood sugar ranges you and your well being care supplier decide is greatest in your goal vary.
The U.S. Facilities for Illness Management and Prevention (CDC) describes low blood sugar ranges as something beneath 70 mg/dL (3.9 mmol/L) in individuals with diabetes.
Severely low blood glucose ranges are thought-about to be something beneath 54 mg/dL (3.0 mmol/L). This may require speedy therapy with both fast-acting glucose or glucagon (if the particular person can not chew or swallow).

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

What’s hypoglycemia unawareness?
Hypoglycemia unawareness is a situation during which somebody doesn’t get the standard bodily warning indicators their blood sugar ranges are going low.
It’s way more widespread than many individuals assume 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 often called sulfonylureas, each of which may 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 growing hypoglycemia unawareness.
Hypoglycemia unawareness considerably will increase the chance 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 understanding, this will result in hypoglycemia turning into extreme. With out quick therapy, it has the potential to end in acute problems similar to lack of consciousness, seizures, and in excessive instances, life-threatening outcomes.
Moreover, recurring episodes of extreme hypoglycemia can contribute to long-term problems, similar 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 chance elements for hypoglycemia unawareness?
There are a number of identified danger elements for growing hypoglycemia unawareness, together with the next:
- Lengthy-term use of insulin. Analysis signifies that the chance of growing hypoglycemia unawareness will increase with the length of insulin therapy. For instance, in one 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 latest and/or recurrent low blood sugar occasions (similar to lows at night time, 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 aren’t totally understood. Nevertheless, a number of key elements are thought to contribute to its improvement:
- 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. 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 chance 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 purpose 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, similar 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 drugs deal with circumstances 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 despair, may 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 might probably additionally enhance your probability of going low.
Are there problems from hypoglycemia unawareness?
Having hypoglycemia unawareness considerably will increase the chance of each short- and long-term problems.
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 capabilities, making it troublesome to carry out on a regular basis actions similar to driving, studying, and dealing, and might cloud judgment and cognition.
If you happen to don’t deal with your low blood sugar shortly sufficient, it could even end in extra severe problems, similar to lack of consciousness, seizures, coma, and mind harm. Over time, recurring extreme hypoglycemia may also contribute to cardiovascular problems and cognitive decline.
How will you stop and deal with hypoglycemia unawareness?
Speak to your healthcare supplier should you discover that you’re not detecting signs of low blood sugar.
Most individuals with diabetes ought to have the ability to really feel low blood sugar ranges after they attain 70 mg/dL (3.9 mmol/L), though this stage can range for individuals with a historical past of frequent lows.
If an individual with diabetes has hypoglycemia unawareness, formal applications exist to enhance blood glucose consciousness. Moreover, your well being care supplier can focus on potential methods to grow to be extra delicate to your blood sugar ranges falling.
Your healthcare supplier could counsel reducing 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 might also have the ability to catch low blood sugars sooner by checking your blood sugar ranges extra regularly or carrying a steady glucose monitor (CGM). Carrying fast-acting carbohydrates with you to right away deal with lows can be beneficial, as is having a glucagon package readily 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. Nevertheless, this selection 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 many who have entry to the expertise, 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 means of an algorithm to find out how a lot insulin to ship through a pump. Insulin is lowered or paused as blood sugar ranges lower, serving to to forestall hypoglycemia.
In the US, 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.
It’s possible you’ll not at all times have the ability to reverse hypoglycemia unawareness, however you’ll be able to enhance your sensitivity, largely by avoiding low blood sugar ranges for some time.
