00:07 – 00:08
Hello.
00:08 – 00:11
Thanks for joining me for Severe Low Blood Sugar Basics.
00:12 – 00:14
Life is a journey and so much of it happens
00:14 – 00:16
while we are busy making other plans.
00:16 – 00:19
And as much as we would like, we can’t plan for everything.
00:20 – 00:23
Sometimes, even when people with diabetes are taking steps
00:23 – 00:25
to prevent severe low blood sugar
00:26 – 00:29
life can still get in the way.
00:30 – 00:32
A1C is a blood test
00:32 – 00:34
that measures average blood sugar over the past 3 months.
00:35 – 00:39
Because A1C doesn’t look at how your blood sugar levels vary from hour to hour,
00:39 – 00:42
or from day to day, you may still be at risk
00:42 – 00:46
for severe low blood sugar, regardless of your A1C level.
00:47 – 00:49
Now, let’s talk about
00:49 – 00:51
some of the causes of severe low blood sugar.
00:52 – 00:56
In one study, people with diabetes who take insulin reported
00:56 – 00:58
a range of everyday circumstances that
00:58 – 01:00
can lead to low blood sugar emergencies.
01:00 – 01:03
These include not eating enough food,
01:03 – 01:05
unexpected or unusual physical activity,
01:06 – 01:08
taking the wrong amount of insulin,
01:08 – 01:10
situations that cause stress,
01:10 – 01:12
changing blood sugar levels,
01:12 – 01:16
and not noticing signs or symptoms of low blood sugar.
01:17 – 01:21
A severe low blood sugar emergency could happen anytime, and anywhere.
01:23 – 01:26
So, people with diabetes should be prepared with an emergency plan,
01:26 – 01:28
just in case.
01:29 – 01:31
Things to remember.
01:31 – 01:36
One, you may be at risk for severe low blood sugar, regardless of your A1C level.
01:36 – 01:41
Two, a range of everyday circumstances can lead to low blood sugar emergencies.
01:41 – 01:44
Three, be prepared with an emergency plan
01:44 – 01:46
just in case.
01:48 – 01:50
Thank you for joining us for Severe Low Blood Sugar Basics.

Did You Know?
Having one single low blood sugar event increases your risk of having a severe low blood sugar event in the future.
What Causes Severe Low Blood Sugar?
You may have a severe low blood sugar event for several reasons, and many of them are out of your control. But understanding why a severe low blood sugar event may happen in the first place can help you feel more in control—and potentially help you recognize low blood sugar before it becomes severe. Some common causes of severe low blood sugar include:

Taking too much medicine or taking the wrong medicine

Missing a meal or not being able to eat enough

Medicine that may increase the risk of low blood sugar (for example, insulin, glimepiride, or glipizide)

Exercising vigorously or for a long time

Eating foods that are high in fat and low in carbohydrates

Drinking alcohol

CGM* readings that are not accurate

Other medical conditions (for example, kidney disease)
*CGM=continuous glucose monitor

Did You Know?
Most people with diabetes feel symptoms, such as sweating or anxiety, when they have low blood sugar. Others have difficulty noticing as they do not feel any symptoms, so they don’t know they need to treat it. This is known as “hypoglycemia unawareness” or “impaired hypoglycemia awareness.”
Hypoglycemia unawareness puts the person at higher risk for severe low blood sugar. People with hypoglycemia unawareness need to take extra care to check blood sugar frequently, especially before and during critical tasks such as driving.

Learning About Your Own Low Blood Sugar Events

If you’re having low or severe low blood sugar events, but you don’t know the reasons, try the tips below. They may help you learn more about what’s causing your low blood sugar.
Keep a logbook (hand written or electronic) every day, or as often as you can. You can write down your:
- Blood sugar levels
- Medicines you take
- How often and how much you exercise
- Foods you eat and alcohol you drink
Think about your previous low or severe low blood sugar events. Write down any early warning signs or symptoms you noticed. Also, write down any changes in your daily activities around the time of low
blood sugar events.
Discuss your logbook, and CGM data if available, with your healthcare provider. They may be able to
help you see trends related to your low blood sugar event

Did You Know?
A higher A1C level does not protect you from severe low blood sugar. A1C is a blood test that measures your average blood sugar over the past 3 months. Because A1C doesn’t look at how your blood sugar levels vary from hour to hour, or from day to day, you may still be at risk for severe low blood sugar, regardless of your A1C level.
