When You Have Low Blood Sugar
First, eat or drink 15 grams of a fast-acting carbohydrate, such as:
- Three to four glucose tablets
- One tube of glucose gel
- Four to six pieces of hard candy
- 1/2 cup fruit juice
- 1 cup skim milk
- 1/2 cup soft drink
- 1 tablespoon honey
Fifteen minutes after you’ve eaten a food with sugar in it, check your blood sugar again. If your blood sugar is still less than 70 mg/dL, eat another serving of one of the foods listed above. Repeat these steps until your sugar becomes normal.
Cgm Studies In Nondiabetic Individuals
One study from 2009 entitled Reference Values for Continuous Glucose Monitoring in Chinese Subjects looked at the glucose levels of 434 healthy adults using CGM and found the following:
- On average, their daily glucose levels stayed between 70140 mg/dl for 93% of the day, with very small portions of the day spent above 140 mg/dl or below 70 mg/dl.
- Also, their mean 24-hour glucose levels were around 104 mg/dl
- 1-hour post-meal glucose values average 121-123 mg/dl for breakfast, lunch, and dinner
- 3-hour post-meal glucose values were around 97-114 mg/dl.
- Peak post-meal values appeared to be around 60 minutes after eating.
- Mean fasting glucose was 86 ± 7 mg/dl.
- Mean daytime glucose was 106 ± 11 mg/dl.
- Mean nighttime glucose was 99 ± 11 mg/dl.
A 2010 study, Variation of Interstitial Glucose Measurements Assessed by Continuous Glucose Monitors in Healthy, Nondiabetic Individuals, looked at a healthy population of 74 individuals that included children, adolescents, and adults during daily living using CGM. This research showed that:
- Glucose levels stayed between 71-120 mg/dl for 91% of the day.
- Levels were lower than 70 mg/dl for 1.7% of the time and greater than 140 mg/dl, only 0.4% of the time.
- Mean 24-hour glucose was 98 ± 10 mg/dl.
- Mean fasting glucose of 86 ± 8 mg/dl.
Compared to the first study mentioned, these healthy, nondiabetic individuals appeared to have a tighter range of glucose, spending the vast majority of the 24-hour period between 71-120 mg/dl.
Maintaining Healthy Blood Sugar Levels
- Eat a healthy breakfast containing fiber and protein within an hour of waking up to prevent hypoglycemia.
- Always eat healthy fats, protein, and fiber with each meal, as this slows the digestive process and the number of carbohydrates released into the bloodstream, keeping blood sugar levels stable.
- Exercise regularly to burn off extra blood sugar.
- Drink plenty of water and avoid sugary drinks, such as soda, sports drinks, and juice, as these quickly raise blood sugar levels.
- Keep a supply of hard candy, juice boxes, or glucose tablets on hand in case of low blood sugar crashes. If your loved one has hypoglycemia, he or she should consume a sugary snack or drink as soon as possible and then recheck his or her levels.

What Should I Do If This Happens
People and their partners or roommates should learn to recognize the signs of nighttime hypoglycemia. Be prepared! Ask your doctor for an emergency glucagon kit. This kit contains a fast-acting medication that can be injected if the person cant be woken up. Store the kit in a bedside drawer for easy access.
DO NOT PUT ANYTHING INTO A PERSON’S MOUTH IF THEY ARE ASLEEP OR CANNOT SIT UP.
If the person cannot be woken: If there is no emergency glucagon kit, call 911. If the person has a glucagon kit, the partner or roommate should follow the instructions to fill the syringe and inject the medicine. Once fully awake, he/she should eat a meal and check their blood glucose every few hours using a home test kit. After giving the injection, the persons doctor should be notified.
If the person can be woken up and sit without support: They should be given a fast-acting glucose source. Good options include hard candy, fruit juice or glucose paste or tablets, which can be purchased at most pharmacies. Once the person is fully awake, they should eat a meal and check their blood glucose every few hours using a home test kit.
Summary Of Normal Glucose Ranges
In summary, based on ADA criteria, the IDF guidelines, a persons glucose values are normal if they have fasting glucose < 100 mg/dl and a post-meal glucose level < 140 mg/dl. Taking into account additional research performed specifically using continuous glucose monitors, we can gain some more clarity on normal trends and can suggest that a nondiabetic, healthy individual can expect:
- Fasting glucose levels between 80-86 mg/dl
- Glucose levels between 70-120 mg/dl for approximately 90% of the day
- 24-hour mean glucose levels of around 89-104 mg/dl
- Mean daytime glucose of 83-106 mg/dl
- Mean nighttime glucose of 81-102 mg/dl
- Mean post-meal glucose peaks ranging from 99.2 ± 10.5 to 137.2 ± 21.1 mg/dl
- Time to post-meal glucose peak is around 46 minutes 1 hour
These are not standardized criteria or ranges but can serve as a simple guide for what has been observed as normal in nondiabetic individuals.

High Blood Sugar: Hidden Dangers
In the short term, high blood sugar levels can zap your energy, cause excessive thirst and urination, and blur your vision. High blood sugar levels can also lead to dehydration, dry and itchy skin, and infections. Minimizing the time spent above your target blood sugar range can help you feel your best and will help prevent complications and injury to your body.
Over time, high blood sugar affects many parts of the body. Chronic high blood sugar can start to cause noticeable changes, including:
- Memory problems
- Vision problems like blurriness, diabetic retinopathy, and blindness
- Gum disease that leads to tooth loss, which can make eating healthy foods difficult due to problems chewing
- Heart attack and stroke due to increased plaque build-up in the vessels and other vascular issues
- Kidney disease, which can lead to the need for dialysis or a kidney transplant
- Nerve damage that can cause decreased sensation in the feet and legs which increases the risk for wounds to turn into serious infections and even amputation
Nerve damage from high blood sugar can also cause a variety of symptoms including:
- Pain and tingling in the feet and hands
- Difficulty emptying your bladder
- Problems during the digestion process after eating, which can cause food to sit in the stomach too long and lead to nausea, vomiting, and erratic blood sugar levels
Checking your blood sugar frequently and taking immediate action when it is above range can reduce your risk of complications.
High Blood Sugar Level Causes
Several types of diabetes and medical conditions are the primary cause of high blood sugar levels. Most of which are unpreventable issues but are the reason for a spike in high blood sugar. The causes for high blood sugar levels are as follows:
Causes of low blood sugar levels are very different and are as important to be aware of, as they are in fact easier to control.

How To Measure Blood Sugar Levels
There are two main ways to check your blood sugar levels:
Type 1 diabetics, along with some type 2 diabetics, who require insulin medication, must check their blood sugar at least four times per day, says Mathioudakis. Typically, this should be done before a meal, one to two hours after a meal, and at bedtime.
The timing of these measurements can help determine how much insulin to use. For example, it can be important to use more insulin after a high-sugar meal, or to avoid falling into hypoglycemia while you’re sleeping.
To check your blood sugar at home, you should use blood glucose tests, such as a glucose meter or continuous glucose monitor . Both devices measure blood sugar with the unit mg/dL, which means a milligram of sugar per deciliter of blood.
If you don’t have diabetes, but you may be at risk, your doctor might have you take an A1C test during a yearly check-up. This test reports results as a percentage the higher the percentage, the higher your blood sugar has been in the past three months. Those with diabetes should get an A1C test at least twice a year and sometimes every three months.
How To Reduce Blood Sugar
You can take steps to reach your blood sugar goals as soon as you find out that it is high. This is how to reduce blood sugar if you have a single high reading that may be dangerous:
- Ask your doctor what to do if you missed a dose of insulin or another diabetes medication
- Ask your doctor if your medication types and doses are still appropriate for you
- Drink water to dilute the sugar
- Exercise for 15 minutes
- Eat a small protein snack, such as a hard-boiled egg, ½ ounce of peanuts or pistachios or other nuts, ½ cup of beans, or ½ cup of plain yogurt or cottage cheese
If you have chronically high blood sugar in prediabetes or diabetes, you can follow this treatment plan:
- Exercise regularly, assuming your doctor approves it
- Lose weight if you are overweight or obese
- Eat a higher proportion of vegetables, whole grains, lean proteins, healthy fats, and fruit
- Limit sugary foods and beverages, fried foods, refined starches, and processed and fatty red meats
- Beware of starchy vegetables such as sweet potatoes, which can spike your blood sugar. Check out our guide of which veggies to avoid!

Faq: How Low Can Blood Sugar Go Before Death
If your blood sugar drops below 70 milligrams per deciliter , you may have symptoms, such as feeling tired, weak, or shaky. If your blood sugar drops very low and you do not get help, you could become confused or drowsy or even lose consciousness and possibly die.
How low can blood sugar go before you die?
- Doctors say that a blood sugar level below 50 is fatal. Levels below 60, even in a healthy person, are potentially fatal, especially if the blood sugar drops quickly.
What Level Of Blood Sugar Is Dangerous
Higher blood sugar than normal is always a matter of concern. When should you become vigilant looking at your glucometer?
If you are a non-diabetic person then it is a basis of distress if your glucometer shows a number higher than 140mg/dl and in case of diabetic the range increases to 180 200 mg/dl. This condition is known as hyperglycemia and calls for the necessity to consult with a doctor.

Blood Sugar Levels During Pregnancy
The NIDDK states that gestational diabetes is high blood sugar that occurs during pregnancy if you were not diabetic before getting pregnant. Healthy blood sugar during pregnancy can help lower your risk of developing type 2 diabetes later. It can also lower the risk of your baby being born prematurely, at a high birth weight, and having respiratory problems.
Blood sugar and insulin levels during the first trimester of pregnancy tend to be lower than usual, but they rise during the late second and early third trimesters. You can be diagnosed with an oral glucose tolerance test .
These are the steps for the 2-step strategy.
- Drink a solution with 50 grams of glucose about the amount in 1 16-oz. bottle of a soft drink
- Get your blood drawn after 1 hour. IF the value is high, retest
- Fast overnight
- Drink a solution with 100 grams of glucose about the amount in 12 peanut butter cups
- Get your blood drawn immediately and after 1, 2, and 3 hours
Or, your doctor might use the 1-step strategy with a 2-hour OGTT:
- Fast overnight
- Drink a solution with 75 grams of glucose
- Get your blood drawn immediately and after 1 and 2 hours
These are some values to know from NIDKK related to gestational diabetes and healthy blood sugar in pregnancy.

|Baseline: at least 105 mg/dl1 hour: at least 190 mg/dl2 hours: at least 165 mg/dl3 hours: at least 145 mg/dl|
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.

According to the American Diabetes Association, screening for diabetes is recommended in people over 45 , or at any age if you have certain risk factors, including :
- Being overweight, obese, or physically inactive
- Having a close relative with diabetes
- Belonging to a certain race/ethnic group
- Having signs of insulin resistance or conditions associated with insulin resistance, such as high blood pressure , low good cholesterol and/or high triglycerides , and polycystic ovary syndrome

What Causes Hypoglycemia In A Child
Hypoglycemia can be a condition by itself. Or it can be a complication of diabetes or other disorder. Its most often a problem in someone with diabetes. It occurs when theres too much insulin. This is also called an insulin reaction.
Causes in children with diabetes may include:
Too much insulin or oral diabetes medicine
The wrong kind of insulin
Incorrect blood-glucose readings
Tingling feelings around the mouth
Nightmares and confusion on awakening
The symptoms of hypoglycemia can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

What Are Blood Sugar Levels
Blood sugar levels, also known as blood glucose level, is the level of sugar/glucose present in the blood. Glucose is a simple version of sugar which comes from the food we eat. Therefore, the more food you consume with high sugar levels over a period of time, will typically increase your blood sugar level.
Glucose comes from the foods we eat and its sugar content. When a person consumes a food with high sugar content, that is turned into glucose. The glucose is then absorbed into the bloodstream with the support of insulin. This is then distributed between the bodys cells and used as energy.
Foods high in glucose include most carbohydrates and a handful of proteins and fats. Most foods contain glucose as it is simply a natural sugar that occurs in most dietary forms. However, it is carbohydrates that contain the most sugar and 100% of it turns into glucose, through the process mentioned above, once consumed. The concentration of glucose present in the blood will determine your blood sugar level.
Here is a quick video explaining Blood sugar levels chart :
Your blood sugar level can either be low, normal or high. Depending on what you eat and health conditions, it will vary from person to person. Here is a breakdown of how your blood sugar works and how low or high blood sugar levels happens:
What Are Normal Blood Sugar Levels
You might want to measure your blood sugar before meals to get a baseline, and then two hours after your meal to measure your normal blood sugar level. Your doctor might also suggest measuring blood sugar before bed to be sure you have been eating well throughout the day and can go to sleep with peace of mind.
These are considered within the range of normal:
- Less than 140 mg/dl if you do not have diabetes.
- Less than 180 mg/dl if you have diabetes.

After You Have Low Blood Sugar
If your low blood sugar was mild , you can return to your normal activities once your blood sugar is back in its target range.
After you have low blood sugar, your early symptoms for low blood sugar are less noticeable for 48 to 72 hours. Be sure to check your blood sugar more often to keep it from getting too low again, especially before eating, physical activity, or driving a car.
If you used glucagon because of a severe low , immediately call your doctor for emergency medical treatment. If you have had lows several times close together , you should also tell you doctor. They may want to change your diabetes plan.
