Severe Low Blood Sugar
As your low blood sugar gets worse, you may experience more serious symptoms, including:
- Feeling weak.
- Having difficulty walking or seeing clearly.
- Acting strange or feeling confused.
- Having seizures.
Severe low blood sugar is below 54 mg/dL. Blood sugar this low may make you faint . Often, youll need someone to help you treat severe low blood sugar.
People with diabetes may experience low blood sugar as often as once or twice a week, even when managing their blood sugar closely. Knowing how to identify and treat it is important for your health. Learn how to treat low blood sugar.
Brain Desensitization To Hypoglycemia
If a person has frequent episodes of hypoglycemia , the brain becomes “used to” the low glucose and no longer signals for epinephrine to be released during such times. More specifically, there are glucose transporters located in the brain cells . These transporters increase in number in response to repeated hypoglycemia . As a result, what was once the hypoglycemic threshold for the brain to signal epinephrine release becomes lower. Epinephrine is not released, if at all, until the blood glucose level has dropped to even lower levels. Clinically, the result is hypoglycemic unawareness.
Since repeated hypoglycemia is common in people with diabetes who strive to keep their glucose levels near normal, the incidence of hypoglycemic unawareness becomes more prevalent in patients who follow ‘intensive treatment’ protocols.
The most common treatment for this condition is to liberalize the patient’s target glucose levels, in an attempt to decrease the frequency of hypoglycemic episodes. Hypoglycemic unawareness will sometimes disappear when the frequency of hypoglycemic episodes has declined, but this is not always the case.
When It’s Time To Call A Doctor
If any of the symptoms mentioned have begun to impact your life, such as fatigue so severe you can’t stay awake through the day, it’s a good idea to consult your physician. Dr. Fruge warns that “unstable blood sugar levels could put you at higher risk of heart disease and stroke and it is a red flag for serious health issues” — so blood sugar issues should be taken seriously.
You should also see a doctor if you’re experiencing symptoms of hypoglycemia and haven’t been diagnosed with diabetes or any other underlying condition.
If you do have diabetes and your hypoglycemia isn’t responding to the treatments described above, that’s another good cue to call your health care provider.
If testing reveals you have Type 1 diabetes, you’ll need to continue to test your blood sugar levels as often as instructed by your physician, take insulin regularly and participate in regular exercise. This may mean you will need a new glucose monitoring system, so ask your doctor what they recommend. If you’re diagnosed with Type 2 diabetes, you’ll most likely need to do the same as for Type 1, as well as working with health care professionals to make lifestyle changes such as improving nutrition and planning workouts. Medication may be necessary as well.
Healthy eating, regular exercise and other lifestyle changes can help alleviate symptoms and possibly even reverse prediabetes.

How Can I Stop My Blood Sugar From Crashing
Here are a few ways to avoid hypoglycemic episodes:
- Get in the habit of self-monitoring your blood glucose. Keeping track of when your blood sugar drops can help you recognize aspects of your routine that may be contributing to your hypoglycemia. Dr. Klonoff recommends a continuous glucose monitor. Its the best tool for automatically checking your blood glucose levels around the clock, he says.
- Change your meal plan. When, what, how much, and how often you eat all play a big part in your blood glucose levels. A dietitian can teach you about healthy, well-balanced food choices that will make it easier for you to maintain an acceptable blood sugar range.
- Keep a stash of glucose tablets on hand. With your doctor’s recommendation, make sure you always have glucose tablets with you. You can stick them in your briefcase, purse, car, desk, school locker, etc. You may also want to keep snacks nearbyfor example, cheese or peanut butter crackers, although doctors suggest over-the-counter glucose tablets for more accurate dosage. Do not eat a healthy sugar-free candy bar during hypoglycemia, warns Dr. Klonoff. Its lack of sugar means that it will not raise your blood glucose level sufficiently when you want it to.
- Certain drinks can help get your blood sugar up as well. Try 8 oz. of fruit juice, a soft drink , or a cup of milk.
If A Person Is Unconscious
If a person loses consciousness because of severe hypoglycaemia, they need to be put into the recovery position and given an injection of the hormone glucagon . The injection will raise their blood glucose level.
The injection should be carried out by a friend or family member who knows what they’re doing, or by a trained healthcare professional.
You should dial 999 to request an ambulance if:
- a glucagon injection kit isn’t available
- there’s nobody available who’s trained to give the injection
- the injection is ineffective after 10 minutes
Never try to put food or drink into the mouth of someone who’s unconscious as they could choke.
If you’re able to give a glucagon injection and the person regains consciousness, they should eat some longer-acting carbohydrate food, such as a few biscuits, a cereal bar or a sandwich.
You should continue to monitor the person for signs of recurring symptoms in case they need to be treated again.

What Is Hypoglycemia And Low Blood Sugar
Hypoglycemia is the state of having a blood glucose level that is too low to effectively fuel the bodys cells.
Glucose, which comes from carbohydrates found in foods, is a main source of energy for all of the cells of the body and, especially, the brain. While the body is quite good at extracting glucose from the foods we eat, it relies on a hormone called insulin to actually get the glucose inside the cells of specific organs: the liver, fat, and muscle.
We can think of insulin as holding the key to a cell without insulin, the glucose just remains in the blood, where its also known as blood sugar. During an episode of hypoglycemia, theres not enough glucose in the blood. The normal range is approximately 70 to 150 mg/dl .
Hypoglycemia is most common in newborns. In older children, its most often seen as a complication of insulin therapy for diabetes but can sometimes have other causes as well.
In the majority of cases, hypoglycemia is temporary, easily treated, and usually does not have serious consequences. There are several rare disorders in which hypoglycemia is recurrent and potentially life-threatening. However, with timely diagnosis and appropriate treatment, these can be effectively managed.

Where Can I Find Support
The Hypoglycemia Support Foundation, established nearly 40 years ago, is a national group that offers many resources, including advocacy. They offer salons so that you can personally connect with people like you who are also dealing with bouts of low blood sugar.
Occasionally blood sugar crashes are so extreme they require emergency room care for an immediate dextrose IV treatment. If you have diabetes, wear a medical bracelet that does TK thing? What will this bracelet have on it? A number of one of your contacts? Can you answer and smooth out with this line? have a circle of people who serve as close contacts and are aware of your condition and how to help.
Nighttime Low Blood Sugars
You may experience a low blood sugar night. The low blood sugar might wake you up and your symptoms might be similar to those you have during the day. However, the symptoms may be different. You might have nightmares, sleep poorly, perspire, or feel hot and cold. In the morning you may have a headache, feel nauseated, or feel confused. Notify your doctor if this happens. Check your blood sugar at the time you have the symptoms.
Treatment for a low blood sugar that occurs at night is the same as described earlier.
Your doctor may request that you check a 3:00 a.m. blood sugar 1 to 2 times per week in order to detect any low blood sugars during the night.

Dont Drive When You Have Low Blood Sugar
It’s dangerous. If you’re driving and you have hypoglycemia symptoms, pull off the road, check your blood sugar, and eat a sugary food. Wait at least 15 minutes, check your blood sugar, and repeat these steps if needed. Eat a protein and carbohydrate source before you drive on. Be prepared. Keep a sugar source, such as glucose tablets, in your car at all times for emergencies.
Check Your Blood Sugar Often
Talk with your provider about when you should check your blood sugar every day. People who have low blood sugar need to check their blood sugar more often.
The most common causes of low blood sugar are:
- Taking your insulin or diabetes medicine at the wrong time
- Taking too much insulin or diabetes medicine
- Taking insulin to correct high blood sugar without eating any food
- Not eating enough during meals or snacks after you have taken insulin or diabetes medicine
- Skipping meals
- Waiting too long after taking your medicine to eat your meals
- Exercising a lot or at a time that is unusual for you
- Not checking your blood sugar or not adjusting your insulin dose before exercising
- Drinking alcohol

If you dont feel better after three tries, or if your symptoms get worse, call your healthcare provider or 911. Healthcare providers can use a medication called glucagon. They inject it with a needle or squirt it up your nose. Glucagon is also available for home use. Your healthcare provider can prescribe it and teach a family member or friend how to use it in the event of severe hypoglycemia.
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.

Signs Of Low Blood Sugar
With hypoglycemia, the blood sugar falls below the normal, healthy levels mentioned earlier, which can occur for a variety of reasons.
“Although some people with blood sugar problems may not experience symptoms,” Dr. Aldasouqi continued, “there are some key things to look out for. For those with low blood sugar, someone might have symptoms like anxiety, sweating, increased heart rate, confusion, and may go into what is called ‘a hypoglycemic coma’… The term ‘diabetic coma’ is also used by some.”
Other symptoms of low blood sugar may include:
- Tingling or numb lips, tongue or cheek
- Blurry vision
Slurred Speech And Clumsiness
Your sugar-starved brain may change the way you sound. Slurred speech is a common symptom associated with blood sugar levels that drop below 40 mg/dL, according to University of Michigan Health Systems. Combined with clumsiness another sign of low blood sugar you may seem as though you’ve had a few too many cocktails, even if you haven’t touched a drop, according to the National Health Service.

Low Blood Sugar Without Diabetes
Low blood sugar is uncommon in people who don’t have diabetes.
Possible causes include:
- eating large carbohydrate-based meals this is called “reactive hypoglycaemia”
- binge drinking
- fasting or malnutrition
- having a gastric bypass
- other medical conditions including Addison’s disease a non-cancerous growth in the pancreas or a problem with the liver, kidneys or heart
- some medicines, including quinine
See your GP if you think you keep getting low blood sugar. They can arrange some simple tests to check if your blood sugar level is low and try to find out what’s causing it.
What To Do When Your Blood Sugar Levels Drop Too Low
People who use insulin and other diabetes medications are at risk for hypoglycemia. Keep this action plan handy so youÃ¢re prepared.
If you take insulin or diabetes medication, you may be at risk of developing hypoglycemia, or low blood sugar. Without quick attention, hypoglycemia can lead to serious complications, so its important to know what to do if it happens to you or someone close to you.
In very severe cases, hypoglycemia can lead to seizures or loss of consciousness, says a clinical assistant professor of medicine, endocrinology, gerontology, and metabolism at Stanford Health Care, and chief of the Stanford Endocrine Clinic.
ItÃ¢s possible to have hypoglycemia but have no symptoms, according to the National Institute of Diabetes and Digestive and Kidney Diseases . On the other hand, symptoms can also come on rapidly. While symptoms vary from person to person, if you develop mild to moderate low blood sugar you may:
- Feel shaky or jittery
- Be irritable or combative
- Have blurred vision or see double
Some people feel tingling or numbness in their extremities too, says Rodolfo Galindo, MD, an assistant professor of medicine in the division of endocrinology, metabolism, and lipids at the Emory University School of Medicine in Atlanta, and chair of the inpatient diabetes taskforce.

What Is The Best Thing To Eat When Your Blood Sugar Is Low
To avoid overtreating lows with too much simple carbohydrate or food and then facing a rebound high blood sugar, its best to have go-to automatic corrections for hypoglycemia that are quantity limited and unappealing to overeat. Glucose tablets and gels, and candies like Smarties, are predictable, relieve low symptoms quickly, and are hard to overeat. Some people with diabetes count out jelly beans, mini-Swedish Fish, gummies, or hard candy and eat the exact amount that will help their blood sugar. Others take a specific amount of juice or another sugar-containing drink.
How do you know how much of your correction to consume? Similar to the 15-15 rule, the only way to discover exactly how much of your go-to correction your body needs is by checking your glucose levels, eating a source of sugar that has been measured out, and then checking again in roughly 15 minutes. This can help you adjust the amount of your source of sugar to raise your blood sugar to your target , but not overshoot. This is a precision dose of carbs. To learn more, read Adam Browns Defeating the Hypoglycemia Binge.
Do not use a low as a reason to eat treats this can cause your blood sugar to spike later. Plus, it connects a food reward with something you want to avoid , which is an easy way to develop a bad habit.
Checking For Low Blood Sugar Levels
The warning signs of hypoglycemia are the body’s natural response to low blood sugar levels. When blood sugar levels fall too low, the body releases the hormone adrenaline, which helps get stored glucose into the bloodstream quickly. This can make someone:
- start shaking
- have an increased heart rate
If the hypoglycemia isn’t treated, more serious symptoms may happen, such as drowsiness, confusion, seizures, and loss of consciousness.
The only way to know for sure if you’re having a low blood sugar level is to test. Blood sugar levels can be tested with a . This computerized device measures and displays the amount of glucose in a blood sample. But if you can’t quickly check your blood sugar level, it’s important to treat yourself for hypoglycemia immediately to prevent symptoms from getting worse.
Sometimes a person with diabetes may have symptoms of low blood sugar levels, but blood sugar levels are not actually low. This is a called a false reaction. The hormone adrenaline is not just released when blood sugar drops too low it’s also released when blood sugar levels fall quickly when they’re too high. If you’re having a false reaction, you might actually have blood sugar levels in a healthy range but feel as if you have low blood sugar. Testing blood sugar levels before treating yourself for hypoglycemia can help you figure out if you’re having a false reaction.
