Blood Sugar Basics: What Is Blood Sugar

How to Avoid Blood Sugar Spikes after Meal | 7 Easy Tips

The term blood sugar refers to the sugar, or glucose, that is floating around in your bloodstream at any given time. Blood sugar, or blood glucose is the main source of sugar found in your blood, and comes from the food you eat. I

f you are monitoring your blood sugar, it is important to keep these numbers in check according to the American Diabetes Association .

Your blood sugar needs to be in the right range for you to be healthy. At least some glucose is necessary for your muscle, liver, and some other cells to use as fuel so they can function.

At least some sugar is necessary for your cells and organs to function properly. When our blood sugar levels get too low, it is called hypoglycemia. Without enough glucose as fuel, we lose the ability to function normally. This can make us feel weak, dizzy, and sweaty. And it can even lead to loss of consciousness.


On the other hand, blood sugar levels that get too high are also harmful, this is called hyperglycemia. Our blood sugar levels can get too high when we dont have enough insulin, or when our insulin isnt working well. This is the case for people who have prediabetes or diabetes. If it isnt treated, high blood sugar can lead to serious problems that can be deadly

The Centers for Disease Control and Prevention explains that keeping blood sugar levels in the target range is vital. It can help us prevent serious health concerns like heart disease, vision loss, and kidney disease, for example.

Are Some Canadians At Higher Risk For Elevated Blood Sugar Levels Than Others

You may have a higher risk for elevated blood sugars and type 2 diabetes if you:

  • Are 40 or years of age or older
  • Have a close relative with diabetes
  • Are of African, Arab, Asian, Hispanic, Indigenous or South Asian descent
  • Are overweight
  • Have been diagnosed with prediabetes

Some medical conditions can also increase your risk of type 2 diabetes, such as:

  • High blood pressure or cholesterol levels
  • Polycystic ovary syndrome
  • Psychiatric disorders
  • Sleep apnea

Knowing Blood Sugar Levels

If you have diabetes, the frequency of testing your blood glucose level depends on your treatment plan, so follow your doctors advice on the appropriate times for you.


Common times to check are in the morning, before and after meals, before and after exercise, at bedtime, and if you feel sick. Some people may not need to check their blood sugar daily.

What you eat and what you do for physical activity affect your blood sugar. But theres no way to know what effect they have unless you test your blood sugar.

Blood glucose meters are used to test blood sugar levels so you can see if your levels are within the target range. Your doctor will also work with you on your individualized range.

What Is The Normal Blood Sugar Level

The normal blood sugar levels are after eating and before eating are not the same. It becomes essential to know what the normal blood sugar levels are after eating and before eating. After eating the food, the blood sugar levels are less than 140 mg/dL for 2 hours. But when you are on an empty stomach or have been fasting for more than 8 hours, the blood sugar levels are less than 100 mg/dL.


How Can One Tell If I Have Diabetes By Examining My Blood

Understanding Diabetes &  Foods To Lower Blood Sugar Levels ...

Your body converts sugar, also called glucose, into energy so your body can function. The sugar comes from the foods you eat and is released from storage from your bodys own tissues.

Insulin is a hormone made by the pancreas. Its job is to move glucose from the bloodstream into the cells of tissues. After you eat, the level of glucose in the blood rises sharply. The pancreas responds by releasing enough insulin to handle the increased level of glucose moving the glucose out of the blood and into cells. This helps return the blood glucose level to its former, lower level.

If a person has diabetes, two situations may cause the blood sugar to increase:

  • The pancreas does not make enough insulin
  • The insulin does not work properly

As a result of either of these situations, the blood sugar level remains high, a condition called hyperglycemia or diabetes mellitus. If left undiagnosed and untreated, the eyes, kidneys, nerves, heart, blood vessels and other organs can be damaged. Measuring your blood glucose levels allows you and your doctor to know if you have, or are at risk for, developing diabetes.

Much less commonly, the opposite can happen too. Too low a level of blood sugar, a condition called hypoglycemia, can be caused by the presence of too much insulin or by other hormone disorders or liver disease.

Are There Different Recommendations For Blood Sugar Levels In Other Countries

The recommended blood sugar level ranges in countries around the world are very similar. However, there are two different units of measurement that are used when referring to blood sugars, depending on where you live: millimoles per litre and milligrams per decilitre .

The mmol/L measurement is used here in Canada, as well as England, Australia and China, while mg/dL is used in such countries as the United States, France, Japan, Israel and India.


To convert mmol/L to mg/dl, simply multiply by 18. For example, a blood sugar level of 5.0 mmol/L would mean a level of 90 mg/dL .

Here are blood sugar recommendations from some countries other than Canada:

Keeping Your Levels In Range

If you have diabetes, keeping your blood glucose within normal range after a high-carbohydrate meal can be difficult. The type of carbohydrates you choose can make a difference in your blood sugar. Complex carbohydrates, which must be broken down into simple sugars before your body can absorb them, slow the absorption process and help stabilize your blood sugars. The glycemic index defines carbohydrates by their absorption rate. Carbohydrates with a low glycemic index, less than 45, cause a slow steady rise in blood glucose. Whole grains such as oats, wheat, barley, brown rice and lesser known grains such as quinoa help keep your levels within range. Foods high in fiber, such as whole grains, fruits and vegetables, also slow digestion and help stabilize blood glucose after meals. Exercise can also help slow digestion and stabilize peaks in glucose.

Clearing Up Myths About Blood Sugars After Eating

Blood glucose levels, also known as blood sugar levels, can be normal, high, or low. The blood sugar levels are generally measured after 8 hours of eating.


A normal blood sugar range for a healthy adult after 8 hours of fasting is > 70 mg/dL. and < 100 mg/dL.

While a normal blood sugar level in a healthy person after 2 hours of eating is between 90 to 100 mg/dL.

Blood glucose levels change throughout the day. Major factors affecting for such change in the blood glucose levels are as follows:

  • The type of food we consume can impact blood sugar levels. For example, if we eat rich carb food, high-calorie food, the blood sugar levels might increase.
  • The quantity of food also affects our blood sugar levels. Eating too much may increase blood sugar levels.
  • Physical activities impact blood sugar levels. For example, heavy and rigorous work may decrease blood sugar levels, whereas no or less physical activity may increase blood sugar levels. People who succeed in reversing their diabetes get constant support and motivation from Diabetes Reversal Coach. These experts help you decide how much and what type of exercise is needed to maintain your blood sugar levels.
  • Certain medicines disturb blood sugar levels.
  • Medical conditions like hypoglycemia, diabetes, liver disease may cause changes in blood sugar levels.
  • Alcohol consumption can cause our blood glucose level to drop
  • Smoking can lead to Type 2 Diabetes
  • Stress Physical or Mental, can spike your blood sugar levels.

    How Often Is A1c Tested

    To keep A1C levels in check, patients should have the test repeated regularly. If the A1C is less than 5.7, indicating you dont have diabetes, you should have it checked every three years, according to Robert Williams, MD, a family doctor and geriatrician in Lakewood, Colorado, and a medical advisor for eMediHealth. If it is between 5.7 and 6.4, indicating you are at risk of developing diabetes, you should have it rechecked every one to two years. If you have a confirmed diabetes diagnosis, and your blood sugar is well-controlled, you should have an A1C test every six months. If you already have diabetes and your medications change, or your blood sugar is not well-controlled, you should have an A1C test every three months.

    Diabetes Is Diagnosed By Any One Of The Following:

  • Two consecutive fasting blood glucose tests that are equal to or greater than 126 mg/dL
  • Any random blood glucose that is greater than 200 mg/dL
  • An A1c test that is equal to or greater than 6.5 percent. A1c is an easy blood test that gives a three month average of blood sugars
  • A two-hour oral glucose tolerance test with any value over 200 mg/dL
  • Sometimes you may have symptoms of fatigue, excessive urination or thirst, or unplanned weight loss. However, often people have no symptoms of high blood glucose and find a diabetes diagnosis surprising.

    Why Your Blood Sugar Level May Be Low

    Blood Sugar After Eating  How to Manage it Better

    If blood sugar drops below 70 mg/dL, it is below normal levels. This can be caused by a variety of factors, such as:

    • Not eating enough or missing a meal or snack
    • Reducing the amount of carbohydrates you normally eat
    • Alcohol consumption especially if youre drinking on an empty stomach
    • Taking too much insulin or oral diabetes medication based on carbohydrates or activity levels
    • Increased physical activity
    • Side effects from medications

    If you have diabetes, keep your blood glucose meter and sources of fast-acting glucose close by in case your blood sugar drops. This is especially important for people with hypoglycemia unawareness, which is a condition that causes symptoms of low blood sugar to go unnoticed.


    Eating balanced meals and snacks at regular times throughout the day is a big part of maintaining normal blood glucose levels.

    What To Do When Your Blood Sugar Is High Or Low

    High blood sugar can harm you. If your blood sugar is high, you need to know how to bring it down. Here are some questions to ask yourself if your blood sugar is high.


    • Are you eating too much or too little? Have you been following your diabetes meal plan?
    • Are you taking your diabetes medicines correctly?
    • Has your provider changed your medicines?
    • Is your insulin expired? Check the date on your insulin.
    • Has your insulin been exposed to very high or very low temperatures?
    • If you take insulin, have you been taking the correct dose? Are you changing your syringes or pen needles?
    • Are you afraid of having low blood sugar? Is that causing you to eat too much or take too little insulin or other diabetes medicine?
    • Have you injected insulin into a firm, numb, bumpy, or overused area? Have you been rotating sites?
    • Have you been less or more active than usual?
    • Do you have a cold, flu, or another illness?
    • Have you had more stress than usual?
    • Have you been checking your blood sugar every day?
    • Have you gained or lost weight?

    Fasting Plasma Glucose Test

    A fasting plasma glucose test is taken after at least eight hours of fasting and is therefore usually taken in the morning.

    The NICE guidelines regard a fasting plasma glucose result of 5.5 to 6.9 mmol/l as putting someone at higher risk of developing type 2 diabetes, particularly when accompanied by other risk factors for type 2 diabetes.

    Hba1c Test For Diabetes Diagnosis

    An HbA1c test does not directly measure the level of blood glucose, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.

    Indications of diabetes or prediabetes are given under the following conditions:


    • Normal: Below 42 mmol/mol
    • Prediabetes: 42 to 47 mmol/mol
    • Diabetes: 48 mmol/mol

    There are two types of blood sugar levels that may be measured. The first is the blood glucose level we get from doing finger prick blood glucose tests. These give us a reading of how high our levels are at that very point in time.

    The second is the HbA1c reading, which gives a good idea of our average control over a period of 2 to 3 months. The target blood glucose levels vary a little bit depending on your type of diabetes and between adults and children.

    Where possible, try to achieve levels of between 4 and 7 mmol/L before meals and under 8.5 mmol/L after meals. The target level for HbA1c is under 48 mmol/mol .

    Research has shown that high blood glucose levels over time can lead to organ and circulation damage.

    Keeping blood glucose above 4 mmol/l for people on insulin or certain medications for type 2 diabetes is important to prevent hypos occurring, which can be dangerous.


    Your doctor may give you different targets. Children, older people and those at particular risk of hypoglycemia may be given wider targets.

    When levels rise to 9.0, the risk of kidney and eye damage and neuropathy increases. Some people who are newly diagnosed could have levels over 9.0. Lifestyle changes and possibly medication can lower levels quickly. For someone who has long-standing diabetes, levels rise above 9.0 could signal the need for a change in their treatment plan.

    Some labs estimate average blood glucose , which corresponds to home glucose meter readings , allowing patients to understand the results better.
