What Levels Of Blood Sugar Are Dangerous
Human bodies are wonderfully complex organisms, sometimes to a fault. Its really hard to say exactly what levels of blood sugar are dangerous unless they are really dangerous.
What we mean by that is healthy individuals can have glucose levels ranging from 60ish to about 140. Things start to get bad when you exceed these number, but symptoms might not become apparent until youve reached really dangerous territory. Thats why its important to measure.
Preventing Low Blood Sugar
Preventing low blood sugar is better than having to treat it. Always have a source of fast-acting sugar with you.
- When you exercise, check your blood sugar levels. Make sure you have snacks with you.
- Talk to your provider about reducing insulin doses on days that you exercise.
- Ask your provider if you need a bedtime snack to prevent low blood sugar overnight. Protein snacks may be best.
DO NOT drink alcohol without eating food. Women should limit alcohol to 1 drink a day and men should limit alcohol to 2 drinks a day. Family and friends should know how to help. They should know:
- The symptoms of low blood sugar and how to tell if you have them.
- How much and what kind of food they should give you.
- When to call for emergency help.
- How to inject glucagon, a hormone that increases your blood sugar. Your provider will tell you when to use this medicine.
If you have diabetes, always wear a medical alert bracelet or necklace. This helps emergency medical workers know you have diabetes.
What Are Normal Blood Glucose Levels In Healthy Individuals
Blood sugar levels can either be normal, high, or low, depending on how much glucose someone has in their bloodstream. Glucose is a simple sugar thats present in the bloodstream at all times. Normal blood glucose levels can be measured when someone fasts, eats, or after theyve eaten. A normal blood glucose level for adults, without diabetes, who havent eaten for at least eight hours is less than 100 mg/dL. A normal blood glucose level for adults, without diabetes, two hours after eating is 90 to 110 mg/dL.
Many factors affect blood sugar levels throughout the day:
- Type of food consumed, how much, and when
- Physical activity
- Menstrual periods
An ideal blood sugar level for anyone without diabetes or prediabetes, regardless of age, in the morning should be less than 100 mg/dL. Remember, blood sugar levels can fluctuate throughout the day as a result of the factors previously mentioned.

A1c Goals Should Be Individualized
A1c goals should be individualized based on the individual capabilities, risks, and prior experiences, explains Gary Scheiner, MS, CDE, founder of Integrated Diabetes, and author of Think Like a Pancreas.
For example, we generally aim for very tight A1c levels during pregnancy and more conservative targets in young children and the elderly.
However, Scheiner highlights important factors that could justify aiming for a higher A1c, like hypoglycemia unawareness, which is described as when a person with diabetes no longer feels the oncoming warning signs of low blood sugar. This can put you at significant risk for severe low blood sugars resulting seizures or death. To reduce that risk, you would aim for higher target blood sugar ranges.
Someone with significant hypoglycemia unawareness and a history of severe lows should target higher blood glucose levels than someone who can detect and manage their lows more effectively, adds Scheiner. And certainly, someone who has been running A1cs in double digits for quite some time should not be targeting an A1c of 6% better to set modest, realistic, achievable goals.

When To Get Urgent Medical Attention
Contact your diabetes care team immediately if you have a high blood sugar level and experience the following symptoms:
- feeling or being sick
- a fever for more than 24 hours
- signs of dehydration, such as a headache, dry skin and a weak, rapid heartbeat
- difficulty staying awake
These symptoms could be a sign of a more serious complication of hyperglycaemia, such as diabetic ketoacidosis or a hyperosmolar hyperglycaemic state, and you may need to be looked after in hospital.

Blood Sugar Levels: What’s Normal What’s Not And How To Measure Them
What blood glucose levels mean and what range is healthy.
Sugar can lead to high blood sugar and contributes to the development of diabetes.
We all want to keep track of our health in every way we can — you may weigh yourself daily, measure your waist-to-hip ratio, keep track of your blood pressure or monitor your resting heart rate. But how close of an eye do you keep on your blood sugar?
People with diabetes are all too familiar with their blood sugar levels, but the rest of us might not even think about them. However, consistently high blood sugar levels can coexist with Type 2 diabetes and cause serious health conditions like kidney disease, nerve problems or stroke.
Our Health & Wellness newsletter puts the best products, updates and advice in your inbox.
I hope I haven’t scared you away, but when it comes to our health it’s important to know exactly what’s going on inside of our bodies. Without further ado, let’s get into what blood sugar means, how to measure it and everything else you need to know.
How Can Continuous Glucose Monitoring Help You Maintain Optimal Glucose Levels
It is not uncommon for your glucose levels to increase after a meal: you just ate food that may contain glucose, and now your body is working on getting it out of the bloodstream and into the cells. We know that we want to prevent excessive spiking of glucose levels because studies show that high post-meal glucose spikes over 160 mg/dl are associated with higher cancer rates. Spikes are also associated with heart disease. Repeated high glucose spikes after meals contribute to inflammation, blood vessel damage, increased risk of diabetes, and weight gain. Additionally, the data shows that the big spikes and dips in glucose are more damaging to tissues than elevated but stable glucose levels. Therefore, you should strive to keep your glucose levels as steady as possible, at a low and healthy baseline level, with minimal variability after meals.
Keeping your glucose levels constant is more complicated than just following a list of eat this, avoid that foods. Each person has an individual response to food when it comes to their glucose levels studies have shown that two people can have different changes in their glucose levels after eating identical foods. The difference can be quite dramatic. One study found that some people had equal and opposite post-meal glucose spikes in response to the same food.

High Blood Sugar Symptoms
Hyperglycemia is the medical term for high blood sugar. Hyperglycemia happens when the body doesnt have enough insulin or when it cant use insulin correctly. Many things can cause high blood glucose levels like Type 1 diabetes, Type 2 diabetes, stress, illness, or the dawn phenomenon. If you have hyperglycemia or suspect you may have it, talking with a healthcare provider is always a good idea. A doctor can help you determine whats causing your high blood sugar levels and lower it to a healthy range.
Here are some of the most common symptoms that may indicate hyperglycemia:
- Vision loss
You should seek immediate medical attention if your blood sugar reaches 400 mg/dL or higher.
When patients experience any of these accompanied by elevated blood sugar levels, diabetic patients are advised to go directly to the ER to avoid diabetes-induced coma, says Vikram Tarugu, MD, a gastroenterologist and the CEO of Detox of South Florida. Patients who have elevated blood sugar may also present with frothy, ketone-like smelling breath.
Here are some lifestyle changes and medical treatments that can help treat hyperglycemia:
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 taking the wrong medicines. Check your medicines with your pharmacist.
How To Do A Finger
Your healthcare team will show you how to do it the first time, but these are the key steps:
- Wash your hands with soap and warm water. Dont use wet wipes as the glycerine in them can affect the test result. Make sure your hands are warm so its easier to get blood and wont hurt as much.
- Take a test strip and slot it into the meter to turn it on. Some meters will have tests strips built in.
- Remove the cap from your finger prick device and put in a new lancet. Then put the cap back on and set the device by pulling or clicking the plunger.
- Choose which finger to prick but avoid your thumb or index finger . And dont prick the middle, or too close to a nail. Place the device against the side of your finger and press the plunger. Use a different finger each time and a different area.
- Take your meter with the test strip and hold it against the drop of blood. Itll tell you if the test strip is filled, usually by beeping.
- Before you look at your reading, check your finger. Use a tissue to stop bleeding, then use it to take out the lancet and throw it away in your sharps bin.
- You can use the same tissue to take out the test strip and throw that away too. Taking out the strip will usually turn the meter off.
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.
Is testing blood sugar the only way to know your hyperglycemia? What would you do if you dont have glucometer at home?
Just be conscious of the following 7 symptoms:
In this condition, your body starts to burn fat to get energy as the cells dont get enough of it. This produces ketones causing the blood to be acidic and creates a life-threatening condition if left untreated.

When To Call The Doctor
If signs of low blood sugar do not improve after you have eaten a snack that contains sugar, have someone drive you to the emergency room or call your local emergency number . DO NOT drive when your blood sugar is low.
Get medical help right away for a person with low blood sugar if the person is not alert or cannot be woken up.
How Do Carbs Affect Blood Sugar
Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have and stay in your target blood sugar range depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels. Make sure to talk to your health care team about the best carb goals for you.

Managing Your Diabetes Devices
If you are using an insulin pump, talk to your diabetes team about how to best manage hyperglycemia. In general, be sure to check your pump first. Make sure all parts are connected and working correctly. Check your bolus history and temporary basal rate. Also check your insulin to make sure it has not expired or gotten too warm.
If you use a CGM, try not to react to it too often. You might be tempted to give another dose of insulin too soon, before the first one finishes working, which is known as stacking insulin this can cause low blood sugar .
How To Check Your Blood Sugar Levels
As Dr. Emanuele says, glucose monitoring can be an important tool to help you get your blood sugar under control. Typically, you would do it yourself using a glucose meter or glucometer, which analyzes a drop of blood that you draw by sticking your finger with a lancet and placing the blood on a disposable test strip that you insert into the meter. Your blood sugar goals are set by you and your doctor, but blood glucose for an adult without diabetes is below 100 mg/dl before meals and at fasting and less than 140 mg/dl two hours after a meal, notes the ADA.
Some people will check their blood sugar daily or multiple times a day, sometimes using a continuous monitor that is worn on the body particularly those who have type 1 diabetes or who have type 2 but take insulin. Yet how frequently a person should monitor their blood sugar is based on a number of factors, including but not limited to whether theyre on insulin, whether theyâre taking oral medication, and how well their blood sugar is controlled and how old they are.
Meanwhile, keep an eye out for these nine key warning signs and symptoms that blood sugar is too high and talk to your doctor about whether you need to adjust your management plan.

Different Levels And What They Mean
The ranges of safe levels of blood glucose depend on factors such as what time of day it is and when you last ate. Safe levels of blood sugar are high enough to supply your organs with the sugar they need, but low enough to prevent symptoms of hyperglycemia or complications of diabetes which follow the National Institute of Diabetes and Digestive and Kidney Diseases guides. Dangerous levels of blood glucose are outside of this range.
The target levels can also vary if you have diabetes. For example, if you are diabetic and are monitoring your blood sugar, you might get a reading of 65 mg/dl. That is considered to be mild hypoglycemia, and you would be wise to eat 15 grams of fast-acting carbohydrates and retest your blood sugar in 15 minutes.
If you were not diabetic, you probably would not know that your sugar was low because you would not test and because you would not symptoms, and you would not act.
That is fine because your body is capable, under normal circumstances, of raising your blood glucose to healthy levels when needed, even if you have not eaten. It is important to keep them in control to help prevent issues like heart disease or nerve damage.

How Can I Treat High Blood Sugar
Talk to your doctor about how to keep your blood sugar levels within your target range. Your doctor may suggest the following:
- Be more active. Regular exercise can help keep your blood sugar levels on track. Important: dont exercise if ketones are present in your urine. This can make your blood sugar go even higher.
- Take medicine as instructed. If your blood sugar is often high, your doctor may change how much medicine you take or when you take it.
- Follow your diabetes meal plan. Ask your doctor or dietitian for help if youre having trouble sticking to it.
- Check your blood sugar as directed by your doctor. Check more often if youre sick or if youre concerned about high or low blood sugar.
- Talk to your doctor about adjusting how much insulin you take and what types of insulin to use.

Stay Away From Stimulants
Stimulants can affect your sleep cycle in a few different ways. Some stimulants have light addictive properties which create a decreased quality of sleep. Also, the brain needs time to wind down and feel relaxed for quality shut-eye so these drugs will not only make you anxious but they’ll also keep you up at night with the inability to fall asleep. One of the well-known stimulants is caffeine that can be found in Cola, coffee, and some teas. Stay away from this and other stimulants before bedtime to have a more natural night’s sleep.
What Factors Affect Blood Sugar
You can guess that carbohydrate intake and insulin production are at least partly responsible for your blood sugar levels. But the list is much longer — almost every lifestyle choice you make can affect your blood sugar. Here’s just a partial list.
- Exercise can affect insulin sensitivity, leading to lower blood sugar for up to 48 hours.
- Alcohol intake increases insulin production, causing low blood sugar.
- Stress hormones like cortisol can raise blood sugar, because your body wants access to energy in order to escape what it perceives as a dangerous situation.
- Medications, especially statins and diuretics, can raise blood sugar. Statins are used to treat cholesterol, and diuretics for high blood pressure.
- Diet is a major player in blood sugar. Eating too many simple carbs at once can cause levels to skyrocket, while protein intake leads to a slower increase in blood sugar.
- Dehydration raises blood sugar, because with less water in your body the glucose concentration will be higher.
Other surprising factors can affect your blood sugar, like a sunburn or gum disease, so if you’re dealing with a blood sugar issue and can’t figure out what’s causing your spikes and dips, talk to a health care professional.
