Signs And Symptoms Of Low Blood Glucose
Each person’s reaction to low blood glucose is different. Learn your own signs and symptoms of when your blood glucose is low. Taking time to write these symptoms down may help you learn your own symptoms of when your blood glucose is low. From milder, more common indicators to most severe, signs and symptoms of low blood glucose include:
- Feeling shaky
- Color draining from the skin
- Feeling sleepy
- Feeling weak or having no energy
- Blurred/impaired vision
- Tingling or numbness in the lips, tongue, or cheeks
- Nightmares or crying out during sleep
The only sure way to know whether you are experiencing low blood glucose is to check your blood glucose levels, if possible. If you are experiencing symptoms and you are unable to check your blood glucose for any reason, treat the hypoglycemia.
A low blood glucose level triggers the release of epinephrine , the fight-or-flight hormone. Epinephrine is what can cause the symptoms of hypoglycemia such as thumping heart, sweating, tingling, and anxiety.
If the blood sugar glucose continues to drop, the brain does not get enough glucose and stops functioning as it should. This can lead to blurred vision, difficulty concentrating, confused thinking, slurred speech, numbness, and drowsiness. If blood glucose stays low for too long, starving the brain of glucose, it may lead to seizures, coma, and very rarely death.
What Is Hypoglycemia In Children
Hypoglycemia is when the level of sugar in the blood is too low. Glucose is the main source of fuel for the brain and the body. The normal range of blood glucose is about 70 to 140 milligrams per deciliter . The amount differs based on the most recent meal and other things, including medicines taken. Babies and small children with type 1 diabetes will have different goal ranges of blood glucose levels than older children.

What to do next
51 to 70 mg/dL
10 to 15 grams of fast-acting carbs, such as 4 ounces of fruit juice, 6 to 8 hard candies, or 3 to 4 glucose tablets.
Test your blood sugar again in 15 minutes. Repeat the treatment if necessary.
Under 50 mg/dL
Eat 20 to 30 grams of fast-acting carbs, such as 8 ounces of fruit juice, 12 to 16 hard candies, or 6 to 8 glucose tablets.
Test your blood sugar again in 15 minutes. Repeat the treatment if necessary.
What Is Blood Sugar
When you eat, the carbohydrate in your food is broken down into a usable form of energy called glucose. Glucose also known as sugar enters the bloodstream and a hormone called insulin helps move it into our cells.
This process lowers the amount of glucose in the bloodstream. When this process works efficiently, your muscles and organs have the fuel they need without there being too much glucose remaining in the blood.

Translating Your A1c To A Blood Sugar Level
Using this easy calculator from the ADA, you can translate your most recent A1C result to an eAG or estimate average glucose level.
You can also use this translation when working to improve your A1c and achieving closer to normal blood sugar levels. If you know an A1c of 6.5 is an average blood sugar level of 126 mg/dL or a range of 100 to 152 mg/dL, then you can look at your current blood sugar results on your CGM and meter and pinpoint which time of day youre frequently higher than this range.12% = 298 mg/dL or range of 240 347 11% = 269 mg/dL or range of 217 31410% = 240 mg/dL or range of 193 2829% = 212 mg/dL or range of 170 2498% = 183 mg/dL or range of 147 2177% = 154 mg/dL or range of 123 1856% = 126 mg/dL or range of 100 1525% = 97 mg/dL or range of 76 120
Normal blood sugar levels in a person without diabetes can result in an A1c as low as 4.6 or 4.7 percent and as high as 5.6 percent.
Just a decade or two ago, it was rare for a person with type 1 diabetes to achieve an A1c result below 6 percent. Thanks to new and improved insulin and better technology like continuous glucose monitors and smarter insulin pumps, more people with diabetes are able to safely achieve A1c levels in the higher 5 percent range.
How To Treat A Low Blood Sugar Level Yourself
Follow these steps if your blood sugar level is less than 3.5mmol/L or you have hypo symptoms:
You do not usually need to get medical help once you’re feeling better if you only have a few hypos.
But tell your diabetes team if you keep having hypos or if you stop having symptoms when your blood sugar level is low.

The Dangers Of Low Blood Sugar And What You Can Do About It
Your blood sugar fluctuates throughout the day, going up or down depending on the food you eat, how much you exercise, the medications you take, and even your stress level.
Most of the time you probably wont notice these fluctuations because theyre within whats considered a target range. However, if your blood sugar gets too low below 70 mg/DL it can be dangerous, especially if you have diabetes.
This condition is called hypoglycemia and its especially common among patients with diabetes who take certain types of medications. A large global study found that 4 out of every 5 patients with type 1 diabetes, and nearly half of those with type 2 diabetes, reported low blood sugar at least once over a four-week period.1
As long as youre aware of the symptoms of hypoglycemia, there are plenty of things you can do to bring your blood sugar back to a healthy level. However, if left untreated, hypoglycemia can cause serious side effects and potentially land you in the hospital.
The hypoglycemia-diabetes connection
Your body converts carbohydrates in foods like fruits, vegetables, dairy, and bread products into glucose, and requires insulin to transport it into cells and tissues for energy. Normally, when your blood sugar levels drop too low, your body either produces more glucose or releases extra glucose that has been stored in the liver and muscles.

Talk To Your Doctor Or Nurse
If you use insulin and your blood sugar is frequently or consistently low, ask your doctor or nurse if you:
- Are injecting your insulin the right way
- Need a different type of needle
- Should change how much insulin you take
- Should change the kind of insulin you take
Do not make any changes without talking to your doctor or nurse first.
Sometimes hypoglycemia can be due to accidently taking the wrong medicines. Check your medicines with your pharmacist.

How To Help Someone With Diabetes And Low Blood Sugar
More than 30 million Americans at least 9.4 percent of the U.S. population have diabetes. Because of this, your odds of knowing or interacting with someone with diabetes are high.
There may come a day when one of those people needs your help.
Here, well prepare you for that day and answer some of the questions you might have about the situation, regardless of whether the person has type 1 or type 2 diabetes.
How can I tell if someone has diabetes?
You cant tell someone is diabetic just by looking at them. Many people have undiagnosed diabetes and very high blood sugar without realizing it themselves.
Some people with diabetes wear medical bracelets identifying their diagnosis.
How can I tell if someone has low blood sugar?
Someone with low blood sugar may have some or all of these symptoms:
- Anger, anxiety and irritability
If they dont consume something quickly enough to treat the problem, they could have more serious symptoms, including passing out, experiencing mouth or tongue numbness, losing coordination or even experiencing seizures or coma.
If you know someone has diabetes and theyre displaying symptoms of low blood sugar, ask them if theyve checked their blood sugar recently or if they could check it now.
If their blood sugar is low enough, they may not be able to process the question. You can try to get them to eat or drink something to slowly raise it.

Hypoglycemia Unawareness Or Impaired Awareness
The goal is to help a person recognize symptoms of hypoglycemia early on so they can take action sooner. In some cases, if a person does not experience the perceived signs of hypoglycemia this can cause an unawareness. Hypoglycemia unawareness can occur in those patients with diabetes who live with chronically low blood glucose levels. on insulin are at higher risk for hypoglycemia unawareness. The brain and body of those with hypoglycemia unawareness is accustomed to long-standing hypoglycemia, so their normal physiologic response to hypoglycemia is impaired. These people may function and live normally with blood glucose values in the 70s, and only experience symptoms of hypoglycemia when the glucose values drop into the 50s or below. People with hypoglycemia unawareness are at much greater risk of experiencing severe hypoglycemia. It is important to identify those who suffer from hypoglycemia unawareness and find a medication regimen for their diabetes which is safe for them.
At What Number Range Are You Considered Diabetic
Question Originally asked by Community Member teresa At What Number Range Are You Considered Diabetic what numbers must you have to be consider borderline and what number range to be considered to be diabetic such as type 2 diabectic and type 1 Answer Hello teresa, Diagnosis of diabetes is based on blood sugar measurements. The difference between type 1 and type 2 is not based on blood sugar levels, but in the mechanisms that raise blood sugar. Fasting glucose levels above 140 mg/dl on at least two occations are diagnosic for diabetes. Anything above 110mg/dl but less than 140mg/dl after fasting is considered impaired impaired glocose tolerence. There is a formal test, called a glucose tolerance test, that involves ingesting a specified amount of glucose and lthen measuring how the blood sugar levels increase and fall. Likely, anybody with a blood sugar level about 200 mg/dl on at least 2 occasions without fasting is likely diabetic and needs to be treated.

Preventing A Low Blood Sugar Level
If you have diabetes, you can reduce your chance of getting a low blood sugar level if you:
- Check your blood sugar level regularly and be aware of the symptoms of a low blood sugar level so you can treat it quickly.
- Use a continuous glucose monitor or flash monitor to see how your blood sugar levels are changing. Ask your diabetes care team about getting a monitor if you do not already have one.
- Always carry a sugary snack or drink with you, such as glucose tablets, a carton of fruit juice or some sweets. If you have a glucagon injection kit, always keep it with you.
- Do not skip meals.
- Be careful when drinking alcohol. Do not drink large amounts, check your blood sugar level regularly, and eat a carbohydrate snack afterwards.
- Be careful when exercising eating a carbohydrate snack before exercise can help to reduce the risk of a hypo. If you take some types of diabetes medicine, your doctor may recommend you take a lower dose before or after doing intense exercise.
- Have a carbohydrate snack, such as toast, if your blood sugar level drops too low while you’re asleep .
If you keep getting a low blood sugar level, talk to your diabetes care team about things you can do to help prevent it.
Can A Continuous Glucose Monitor Help With Low Blood Sugar
A continuous glucose monitor measures the bodys glucose levels in real-time by sensing the glucose present in tissue fluid . A CGM typically provides your glucose level every five minutes, which can be really helpful for tracking and finding patterns in how your glucose changes throughout the day. With CGM you can see how much time you spend in your target glucose range each day , notice trends, and develop strategies to improve your diabetes management.
CGMs can sound alerts when glucose levels drop below a certain threshold or are predicted to do so soon. This can be especially helpful for people who experience hypoglycemia unawareness, nighttime low blood sugar, or frequent hypoglycemic events. CGMs also allow you to share your glucose readings with your loved ones and care-partners in real time, so that they can let you know or help you out if your blood sugar starts to drop.
If you are interested in trying CGM, ask your healthcare team if the technology is available to you. You can also try ten-days of CGM for free.
