When Should You Check Your Blood Sugar Levels

Blood Sugar 101: What is the HEALTHY range for blood sugar?

Its important that people who suspect they have diabetes or pre-diabetes monitor their glucose levels regularly, checking at least once daily and charting the results in order to know what is normal for themselves. If it seems like something isnt quite right with ones blood glucose. It may be time to talk to a doctor about getting a diabetes diagnosis. Its also important that parents make sure their children are well aware of any symptoms of high or low blood sugar. So they know when they need to alert an adult about what might be going on if their parents are not around.

Why Your Blood Sugar Level May Be High

Based on the ADA guidelines above, if your blood sugar is above 180 mg/dL two hours after a meal, it is considered above the normal range. What might cause your glucose or blood sugar to rise? Consider the following factors:

  • Consuming more carbohydrates or a larger meal than usual
  • Not taking enough insulin or oral diabetes medication based on carbohydrates or activity levels
  • Reduced physical activity
  • Side effects from medications like steroids or antipsychotics

How Does Hba1c Differ From A Blood Glucose Level

HbA1c provides a longer-term trend, similar to an average, of how high your blood sugar levels have been over a period of time.

An HbA1c reading can be taken from blood from a finger but is often taken from a blood sample that is taken from your arm.

Blood glucose level is the concentration of glucose in your blood at a single point in time, i.e. the very moment of the test.

This is measured using a fasting plasma glucose test, which can be carried out using blood taken from a finger or can be taken from a blood sample from the arm.

However, fasting glucose tests provide an indication of your current glucose levels only, whereas the HbA1c test serves as an overall marker of what your average levels are over a period of 2-3 months.

HbA1c can be expressed as a percentage or as a value in mmol/mol . Since 2009, mmol/mol has been the default unit to use in the UK.

Note that the HbA1c value, which is measured in mmol/mol, should not be confused with a blood glucose level which is measured in mmol/l. Use our HbA1c conversion tool to help with switching between the two measurement units.

HbA1c is a measure of how well controlled your blood sugar has been over a period of about 3 months. It essentially gives a good idea how high or low, on average, your blood glucose levels have been.

How is HbA1c measured?

A sample of blood will be take, usually from your arm. The test measures how much glucose has stuck to haemoglobin in the blood.

Normal Blood Sugar Levels In Healthy Individuals

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.
  • Summary

    What Is High Blood Sugar

    Morning Fasting Glucose Range

    If your blood sugar levels are chronically higher than normal, then this is referred to as hyperglycaemia. This is a common issue for those suffering from diabetes. The condition can also affect pregnant women who have gestational diabetes and occasionally those who are severely ill .

    Some of the symptoms of hyperglycaemia include:

    • Increased thirst
    • Blurred vision
    • Issues with concentration and/or thinking

    If severe hyperglycaemia is left untreated the condition can lead to organ and tissue damage as the excess glucose present in the body can make it difficult for the organs and cells to function correctly. The disorder can also impair the immune system response in the healing of wounds and cuts.

    Who Should Monitor Blood Sugar Levels

    If you have type 1 or type 2 diabetes, monitoring your blood sugar regularly will help you understand how medication like insulin, food, and physical activity affect your blood glucose. It also allows you to catch rising blood sugar levels early. It is the most important thing you can do to prevent complications from diabetes such as heart attack, stroke, kidney disease, blindness, and amputation.

    Other people who may benefit from checking their blood glucose regularly include those:

    • Taking insulin

    Why Your A1c Matters

    In a nutshell: your A1c is one of the clearest indicators of your risk for developing diabetes complications like neuropathy , retinopathy , nephropathy , and severe infection in any part of your body that requires healing.

    For instance, a small cut on your toe could become infected due to high blood sugars, struggle to heal, and become severe enough that the infection could lead to an amputation.

    The general guidelines from the American Diabetes Association recommend an A1c at or below 7.0 percent for the best prevention of diabetes complications. Your risk of developing a diabetes complication continues to drop as your A1c drops closer to 6 percent.

    Some people with diabetes aim for A1c levels in the 5s and lower especially those who follow strict low-carb diets like the ketogenic diet and the Bernstein diet. However, this hasnt been proven in research as especially necessary, nor is it reasonably achievable for the larger population of people with diabetes.

    Its also important to remember that your blood sugar levels and your A1c are just information that tells you whether your body needs more or less of factors like insulin, other diabetes medications, changes in your nutrition, and changes in your exercise.

    If you dont like the number youre seeing on your glucose meter or your A1c results, use that number as motivation to make changes in how you safely manage your diabetes in order to get different results.

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

    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.

    Why Your Blood Sugar Level May Be Low

    What Is the Blood Sugar Normal Range that People with Diabetes Should Target?

    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.

    Everyone will respond differently to certain factors, which is why its important to have individualized target glucose levels. To help you reach your target blood glucose goals, work with your healthcare provider to discuss modifications to your diet, physical activity, or medications, and alert them of other factors like a recent illness or stressful event.

    Can You Have High A1c And Not Be Diabetic

    According to one 2009 study, 3.8% of people without a history of diabetes have an elevated A1C level . This group is more likely to have other risk factors for Type 2 diabetes and cardiovascular disease. Researchers found that the following groups were more likely to have an elevated A1C without having a diagnosis of diabetes:

    • Older
    • Obesity
    • Higher C-reactive protein levels

    A high A1C result might signal that there is a problem. Even a modest increase in your blood sugar, above normal levels, can increase your risk of heart disease, even when you dont have full-blown diabetes, says Dr. Bellatoni. A physician can review test results and talk to patients about risk factors and lifestyle changes to improve blood sugar levels.

    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.

    Is Diabetes More Common In Men Or Women

    Studies show that type 1 diabetes is more common in men, and theyre more likely to pass it on to their offspring. However, although women previously showed more indication of type 2 diabetes, it is now equally prevalent between men and women.

    Type 1 diabetes is an autoimmune condition that usually starts in childhood. With type 1 diabetes, your body attacks its own pancreas so it cannot produce insulin. Type 2 diabetes is far more common in adults, and although often milder than type 1, can still cause major health implications, including kidney disease or damage, heart disease, or stroke. Unlike type 1, with type 2 diabetes some insulin can be produced, but the body is either resistant to it or there is not enough. This insulin resistance develops in fat, liver, and muscle cells, hence the extensively researched correlation between obesity and type 2 diabetes.

    Diabetes Is Diagnosed By Any One Of The Following:

    Normal Blood Sugar Levels
  • 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.

    What Else Can I Do To Help Manage My Blood Sugar Levels

    Eating a healthy diet with plenty of fruit and vegetables, maintaining a healthy weight, and getting regular physical activity can all help. Other tips include:

    • Keep track of your blood sugar levels to see what makes them go up or down.
    • Eat at regular times, and dont skip meals.
    • Choose foods lower in calories, saturated fat, trans fat, sugar, and salt.
    • Track your food, drink, and physical activity.
    • Drink water instead of juice or soda.
    • Limit alcoholic drinks.
    • For a sweet treat, choose fruit.
    • Control your food portions .

    Factors That Can Affect Blood Sugar Levels

    If you have prediabetes or diabetes, you may have insulin resistance or an inability to produce insulin. This means your body has difficulty regulating blood sugar levels on its own.

    Its a delicate balance to maintain, so the following list can help you familiarize yourself with factors that can cause your blood glucose levels to go up or down.

    Diabetes By The Numbers

    Staying healthy with type 2 diabetes is a numbers game. Get the scoop on the health indicators you should be measuring and why.

    Thinkstock

    When you have type 2 diabetes, youve got to know your numbers. Its not just about blood sugar. To successfully manage diabetes, there are several measurements that you should take, or have taken, on a regular basis. Keeping track of the following numbers can help you live well with type 2 diabetes and lower your risk of complications.

    Blood sugar levels. This is probably the type 2 diabetes measure youre most familiar with. Testing your blood sugar regularly allows you to see how certain foods, exercise, and other activities affect your blood sugar levels on a day-to-day basis. Many people with type 2 diabetes need to test once or twice a day to make sure blood sugar levels are in target range. If your blood sugar is very well controlled, you may only need to check a few times a week, according to the National Institutes of Health.

    The American Diabetes Association recommends aiming for a blood sugar level between 70 to 130 mg/dl before meals and less than 180 mg/dl one to two hours after a meal. To keep your blood sugar within this range, follow a healthy, well-rounded diet and eat meals and snacks on a consistent schedule. If your blood sugar is not well controlled, talk to your doctor about adjusting your diabetes management plan.

    Normal Blood Sugar Ranges In Healthy Non

    Normal Blood Sugar Range

    For a person without any type of diabetes, blood sugar levels are generally between 70 to 130 mg/dL depending on the time of day and the last time they ate a meal. Newer theories about non-diabetic blood sugar levels have included post-meal blood sugar levels as high as 140 mg/dL.

    Here are the normal blood sugar ranges for a person without diabetes according to the American Diabetes Association:

    • Fasting blood sugar : under 100 mg/dL
    • 1 hour after a meal: 90 to 130 mg/dL
    • 2 hours after a meal: 90 to 110 mg/dL
    • 5 or more hours after eating: 70 to 90 mg/dL

    What Happens During The Test

    Most people can take an A1C test at any time without preparing beforehand. However, a doctor may sometimes request that a person avoids eating or drinking for 8 hours before the test.

    Women who are pregnant may need to drink a sugary beverage 1 hour before the test.

    A doctor or nurse will collect a blood sample, usually from a vein in the arm or hand. They will send the sample to a laboratory for analysis.

    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
    • Alcohol

    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.
