If your test results show you have prediabetes, ask your doctor or nurse if there is a lifestyle change program offered through the CDC-led National Diabetes Prevention Program in your community. You can also search for an online or in-person program. Having prediabetes puts you at greater risk for developing type 2 diabetes, but participating in the program can lower your risk by as much as 58% .

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.

Normal Random Blood Sugar Levels

Normal random blood sugar levels fall within a standard range of between 70mg/dl to 150mg/dl. This variation can be attributed to various factors including the time, type and volume of food consumed during previous meals.

When you eat foods that are high in carbohydrates, pancreatic secretions of glucagon and insulin regulate the glucose levels. However, the main problem arises when the pancreas does not secrete sufficient amounts of insulin to convert glucose into energy.

The condition of extremely high blood sugar is known as Hyperglycemia which can damage various organs resulting in kidney damage, nerve damage, loss of vision, and heart disease. The other extreme of low blood sugar is known as hypoglycemia and the patient might lose consciousness in case the blood sugar level is too low.

In case your blood sugar level does not fall within the normal range, appropriate action should be taken to diagnose the condition. Here are some tests to help diagnose diabetes and help diabetics ascertain how to manage the disease in the best way possible.

It is important to note that very high blood glucose levels can be dangerous and it is important to be aware of the symptoms and risk factors of the following conditions:

If you are struggling to keep your blood glucose levels under control, speak to your GP or consultant who can advise you or refer you onto a diabetes education course.

Diabetes Is Diagnosed By Any One Of The Following:

Normal Blood Glucose Range
  • 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 Is The Random Blood Sugar Level

    Random blood sugar level is the measurement of the level of glucose in your blood. The random blood sugar test is done to detect diabetes in a patient. Diabetes is a metabolic condition in which the person has high blood sugar levels. The rise in the sugar level is due to inadequate insulin functioning or if the body cells are not responding properly to insulin or both.

    Early symptoms of diabetes are excessive urination , excessive hunger , and excessive thirst . It occurs as the sugar build up in the blood is not being absorbed and is filtered out through kidney in large amounts. This can lead to dehydration.

    • Tingling in arms and legs
    • Constantly being tired

    Normal And Diabetic Blood Sugar Ranges

    For the majority of healthy individuals, normal blood sugar levels are as follows:

    • Between 4.0 to 5.4 mmol/L when fasting
    • Up to 7.8 mmol/L 2 hours after eating

    For people with diabetes, blood sugar level targets are as follows:

    • Before meals : 4 to 7 mmol/L for people with type 1 or type 2 diabetes
    • After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes

    Normal Blood Sugar Levels For Adults With Diabetes

    Normally, your pancreas releases insulin when your blood sugar, or âblood glucose,â gets high — after a meal, for example. That signals your body to absorb glucose until levels get back to normal.

    But if you have diabetes, your body doesnât make insulin or doesnât respond to it normally . That can leave your blood sugar too high for too long. Over time, that can damage nerves and blood vessels and lead to heart disease and other problems.

    If you have diabetes, your doctor may ask you to keep track of your blood sugar by testing it at home with a special device called a blood glucose monitor or home blood sugar meter. It takes a small sample of blood, usually from the tip of your finger, and measures the amount of glucose in it.

    Follow your doctorâs instructions about the best way to use your device.

    Your doctor will tell you when and how to test your blood sugar. Each time you do it, log it in a notebook or online tool or in an app. The time of day, recent activity, your last meal, and other things can all affect whether a reading will be of concern to your doctor. So try to log relevant information like:

    • What medication and dosage you took
    • What you ate, when you ate, or whether you were fasting
    • How much, how intense, and what kind of exercise you were doing, if any

    That will help you and your doctor see how your treatment is working.

    Diagnosing Prediabetes Type 2 And Type 1 Diabetes

    Normal Blood Glucose Level according to ADA

    Depending on which country or medical organization you ask, the qualifying numbers for normal versus prediabetes versus diagnosed type 1 or type 2 diabetes can vary slightly. The following blood sugar and A1c the general results are used to diagnosed prediabetes and diabetes according to sources including the American Diabetes Association and Diabetes UK:

    Prediabetes

    • HbA1c: 5.7 to 6.4 percent
    • Fasting: 100 to 125 mg/dL
    • 2 hours after a meal: 140 mg/dL to 199 mg/dL

    Type 1 or 2 diabetes

    • HbA1c: 6.5 percent or higher
    • Fasting: 126 mg/dL or higher
    • 2 hours after a meal: 200 mg/dL or higher

    Please note: Type 1 diabetes tends to develop very quickly which means that by the time symptoms are felt, blood sugar levels are generally well above 200 mg/dL all the time. For many, symptoms come on so quickly they are dismissed as the lingering flu or another seemingly ordinary virus.

    By the time blood sugar levels are tested, many newly diagnosed type 1 patients will see levels above 400 mg/dL or higher. If you do suspect that you or a loved-one has type 1 diabetes, visit your primary care or urgent care immediately and ask for a urine test to measure ketones in addition to testing blood sugar levels and A1c.

    How To Prevent High Blood Glucose Levels

    For maintaining a proper blood glucose level you must maintain a balanced diet for especially for people who are with diabetes. You may talk with your doctor or any dietitian to set up a diet plan. With type 1 diabetes, the timing will be according to its activity and diet. It is important to note that when you eat, how much you eat, and what you eat.

    Most doctors prescribe three to four snacks every day and small meals to maintain the balance between insulin and blood sugar in your body. The accompanying ideas can help keep your glucose within your objective reach:

    • Follow your diabetes meal plan. If that you take insulin or oral diabetes medications, its significant that you be steady about the amount and timing of your meals and bites. The food you eat should be in balance with the insulin working in your body.
    • Monitor your glucose. Depending upon your treatment plan, you may check and record your glucose level many times each week or several times each day. Careful monitoring is the best way to ensure that your glucose level remains within your objective reach. Note when your glucose readings are above or underneath your objective reach.
    • Taking of your medications as prescribed by your doctor.
    • Change your medicine if you change your physical activity. The change relies upon the glucose test results and on the type and length of the activity.
    • Encountering emotional stress, for example, financial loss or working environment challenges

    Still Frustrated With Your Blood Sugar And A1c Results

    Your blood sugars and your insulin or medication needs never stay in one place. If you gain weight or lose weight, your insulin and medication needs will change. If you become more active or less active, your needs will change. If you make drastic or even small changes to your nutrition, your needs will change!

    Working with your diabetes healthcare team, and diabetes coaches who can teach you how to make changes in your overall diabetes management plan are essential. Diabetes is a lifelong learning process.

    Take a deep breath and be patient. If you dont like what youre seeing on your glucose meter, dont get madget studying! Take good notes and work with your team to make changes to reach your goals.

    How Do I Prepare For The Plasma Glucose Level Test And How Are The Results Interpreted

    To get an accurate plasma glucose level, you must have fasted for at least 8 hours prior to the test. When you report to the clinic or laboratory, a small sample of blood will be taken from a vein in your arm. According to the practice recommendations of the American Diabetes Association, the results of the blood test are interpreted as follows:

    Fasting blood glucose level

    • If your blood glucose level is 70 to 99* mg/dL . . .
    • What it means: Your glucose level is within the normal range
  • If your blood glucose level is 100 to 125 mg/dL . . .
  • What it means: You have an impaired fasting glucose level . . .
  • If your blood glucose level is 126 mg/dl or higher on more than one testing occasion
  • What it means: You have diabetes
  • *Values between 50 and 70 are often seen in healthy people

    **The condition of “prediabetes” puts you at risk for developing Type 2 diabetes, high blood pressure, and blood lipid disorders

    Target Blood Sugar Levels For People With Diabetes

    People with diabetes have difficulty creating or using enough insulin, which is the hormone that helps convert glucose into energy. Although there is no universal blood sugar chart for everyone with diabetes, clinical organizations like the ADA and American Association of Clinical Endocrinologists offer guidelines on target blood sugar levels as a starting point.

    Healthcare providers typically tailor normal blood sugar target ranges to an individual diabetes care plan. This includes considering your:

    • Age

    Causes Of Blood Sugar Levels

    Whilst the liver and muscles produce some glucose, most comes from the foods we eat. Food and drinks that are high in carbohydrates are most impactful on blood sugar level. What we eat provides us most of the nutrients our body needs and sometimes, does not need. That is not to say that food is a major cause of blood sugar level increasing or decreasing too dramatically.

    Typically, if a person has health conditions or poor nutrition, this will lead to a spike or decline in blood sugar level. The causes differ from high to low blood sugar levels and are as follows:

    The main goal behind random blood sugar test is to check random blood sugar levels. Having a random blood sugar range of 200mg/dl or more is a clear indication of the presence of diabetes mellitus. With the diagnosis of diabetes, random blood sugar test helps in the timely treatment of the disease through monitoring during and after the treatment.

    To get an accurate reading of your blood sugar level, the best and most effective method is using a glucose meter. This will involve a small prick in your finger so receive a blood sample. The strip is then inserted into the meter and tested.

    You may be wondering what your reading should be. There is no normal reading, an ideal reading differs from person to person. Everyone will get different readings at different times of the day. However, there is a rough range to determining a low, normal and high blood sugar level. Blood sugar level is read in mmol/L, which stands for millimoles per liter. Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:

    Child
    4 5.9 mmol/L< 7.8 mmol/L 4 5.9 mmol/L< 7.8 mmol/L

    It is advised to check it regularly if you are concerned, show regular symptoms or have diabetes. You should check before meals, exercise, before bedtime and after driving. Everyone is different so it is best to ask your doctor if you are unsure how many times and when you should check your blood sugar levels.

    Research shows that over 50% who try to estimate their blood sugar level reading are incorrect. This may be due to over underlying medical conditions that did not know they had or poor lack of judgement. Therefore, this suggests it is very important to test at home to check in on your levels regularly to avoid any unnecessary future complications.

    Low Blood Sugar Chart And Action Plan

    Low blood sugar is also called hypoglycemia. The numbers below represent values in the hypoglycemic range and require action to bring blood sugar levels up into a normal range.

    Alert Level and Treatment Plan
    50 mg/dL or under Red Flag: Blood sugar is critically low and requires immediate treatment.

    If a person is unable to speak and/or is not alert, treat with glucagon via injection or nasal spray. Call emergency medical response if necessary. Do not place food or drink into the mouth.

    If a person is alert and able to speak clearly, treat with 15 grams of rapid-acting carbohydrate such as glucose gel, 4 oz regular soda, or fruit juice. Re-test blood sugar in 15 minutes and repeat as needed to bring blood sugar within range.

    51-70 mg/dL Red Flag: Blood sugar is below normal levels and requires immediate treatment.

    Treat with 15 grams of rapid-acting carbohydrate and re-test in 15 minutes. Repeat treatment as needed to bring blood sugar within range.

    71-90 mg/dL Yellow Flag: Blood sugar levels should be watched and treated as needed.

    If youre having symptoms of low blood sugar, treat with 15 grams of rapid-acting carbohydrate and re-test in 15 minutes.

    Repeat treatment or follow with a meal. If it is meal time, move forward with eating the meal. People often fall into this range when they are late for a meal or have been especially active.

    Normal Blood Sugar Levels Chart

    Every substance present in our body has an optimum level. Above or below that specific range, that particular substance is harmful to our health. And so is sugar. There is a certain range of blood sugar which is considered as standard for almost all age. However, there might be some changes in the level considering different factors like age and other co-morbidities. Lets look at the chart:

    Time
    2 hours after the meal < 140 mg/dl
    5.7-6.4% 6.5%

    Sometimes, random blood is also taken. In this case, the glucose level of 200 mg/dl is considered a diabetic condition.

    Going through the chart you will notice certain terms regarding blood sugar which you need to understand in order to evaluate your own glucose level. So, I will just give a small brief regarding those:

    • Fasting blood glucose: Here, blood sugar is tested after abstaining from food and drink for at least 8 hours.
    • Postprandial blood sugar:In this case, blood sugar is tested 2 hours after a meal to access if its at the optimum level after having a meal or not.
    • Random blood glucose: Blood is tested at any time of the day.
    • HbA1c: It refers to a blood test which is done to evaluate the average level of blood glucose over the past 3 months. HbA1c is also known as glycosylated haemoglobin or A1C. Moreover, fasting is not required before carrying out the test.
