Causes Of High Blood Glucose
- The hormone, insulin, regulates blood glucose levels by stimulating various tissues to take up glucose from the blood. In this way it clears the blood of excess glucose. A deficiency or resistance of the bodys cell to insulin is one the main reasons for hyperglycemia.
- Certain drugs may produce hyperglycemia . Some examples of these hyperglycemia inducing drugs include corticosteroids, beta blockers, thiazide diuretics, niacin, protease inhibitors, amphetamine, olanzapine, duloxetine.
- Other than diabetes, conditions such as acute stress, myocardial infarction , stroke, pancreatic diseases, brain tumors and hormonal dysfunctions of adrenal, pituitary, and thyroid glands could also cause hyper-glycemia.

What Is Fasting Blood Sugar
As the name suggests, fasting blood sugar is the amount of sugar present in your blood after fasting . During these fasting hours, you cannot eat or drink anything except water. The normal range of fasting blood sugar levels varies from 70-100mg/dl. If your blood sugar level is more than this then you may have diabetes.
Fasting sugar is preferred by doctors as it is a reliable number compared to non-fasting sugar levels. After eating different types of food, our blood sugar level fluctuates differently. So, doctors, may not get a correct picture of your blood sugar level. Your doctor may also ask for fasting sugar levels to calculate your insulin resistance.
What Is Gestational Diabetes
It has been reported that on average 2% to 4% of women develop temporary diabetes also known as gestational diabetes
This happens because they are unable to produce an increased amount of insulin to overcome the resistance levels.
In gestational diabetes there is not normally any show of external symptoms normally recognised as characteristic of the disease for example excessive thirst, tiredness and increased urination.
What If The Range Of Your Fasting Blood Sugar Levels Go Up 100 Mg/dl Chart Explained
The chart below will help you get an idea on what goes on in case of changing of fasting blood sugar levels up 100mg/dl and down 70 mg/dl.
When your fasting blood sugar level readings are between 100 and 125 mg/dl, then most probably you may have pre-diabetes.
That is a condition in which your body insulin function is impaired. You may know it also as impaired fasting blood glucose condition.
In case your fasting blood sugar levels figures are higher than 125 mg/dl, than most probably you may have diabetes. Further diagnostic exams will determine what type of diabetes you may have.
Remember: always will be a double check to fully determine if you have diabetes or not.
This means that youve to monitor your fasting blood sugar levels for one week, record the results for reference when consulting your doctor. Then, and only then you will know if you are diabetic or not.
What If The Blood Glucose Check Result Doesnt Sound Right
If youre not convinced that a result is correct, heres a suggested check list:
- Have the strips expired?
- Is the meter too hot or too cold?
- Is the calibration code correct?
- Is the battery low or flat?
All meters will give a different result with a different drop of blood. As long as there is not a big difference there is not usually cause for concern.
The accuracy of all meters can be checked with meter-specific liquid drops called control solutions. If you are concerned, you can arrange to have your meter checked with a control solution. Your Credentialled Diabetes Educator or pharmacist can help you with this.

What Is Blood Glucose
Blood glucose comes from food. When an individual eats, the food is broken down into sugar and sent to the blood. The insulin is what helps the sugar go into the cells. Once this happens, the sugar that has moved from the blood into the cells is used for energy or is stored.
Glucose is known as the bodys main energy source. Too much glucose in the blood, or if it is not absorbed properly, can create health issues both long and short term. To keep a healthy blood sugar level, it is important to:
- Check blood glucose levels
- Keep in contact with your healthcare provider
It is important to keep in contact with a healthcare professional, eat properly, check your blood glucose, and exercise regularly to keep a healthy blood sugar level.
When Should Hba1c Levels Be Tested
Everyone with diabetes mellitus in the UK should be offered an HbA1c test at least once a year.
Some people may have an HbA1c test more often. This may be more likely if you have recently had your medication changed or your health team are otherwise wishing to monitor your diabetes control more than once a year.
Although HbA1c level alone does not predict diabetes complications, good control is known to lower the risk of complications

This test can be done in the lab or the healthcare providers office with a simple finger stickor your doctor may prescribe a meter and have you test regularly at home.
A fasting blood sugar level indicates what your blood sugar is when you havent eaten for at least 8 hours. For adults without diabetes, a normal fasting blood sugar is less than 100 mg/dL. A fasting blood sugar level of 100-125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes.
Chart Of Normal Blood Sugar Levels For Adults With Diabetes Age Wise
The amount of glucose present in blood fluctuates during the day and at night. Our body maintains a level of blood glucose for metabolism. The normal sugar level in a healthy body is between 90 to 100 mg/dL. But sometimes, these blood sugar levels may go high or low due to various factors. Such high or low blood glucose levels are signs of health conditions that need/ require attention and blood glucose can be kept at healthy levels with various Diabetes Reversal Methods and medical attention. This article gives in-depth information about normal blood sugar levels chart for adults with diabetes according to age.

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.
Translating Your A1c To A Blood Sugar Level
Using this easy calculator from the ADA, you can translate your most recent A1C result to an eAG or estimate average glucose level.
You can also use this translation when working to improve your A1c and achieving closer to normal blood sugar levels. If you know an A1c of 6.5 is an average blood sugar level of 126 mg/dL or a range of 100 to 152 mg/dL, then you can look at your current blood sugar results on your CGM and meter and pinpoint which time of day youre frequently higher than this range.12% = 298 mg/dL or range of 240 347 11% = 269 mg/dL or range of 217 31410% = 240 mg/dL or range of 193 2829% = 212 mg/dL or range of 170 2498% = 183 mg/dL or range of 147 2177% = 154 mg/dL or range of 123 1856% = 126 mg/dL or range of 100 1525% = 97 mg/dL or range of 76 120
Normal blood sugar levels in a person without diabetes can result in an A1c as low as 4.6 or 4.7 percent and as high as 5.6 percent.
Just a decade or two ago, it was rare for a person with type 1 diabetes to achieve an A1c result below 6 percent. Thanks to new and improved insulin and better technology like continuous glucose monitors and smarter insulin pumps, more people with diabetes are able to safely achieve A1c levels in the higher 5 percent range.

Blood Sugar Level Chart By Age
Blood sugar levels tend to rise with age due to an increase in insulin resistance and decrease in insulin sensitivity. In one study by the National Health Institute , each extra decade of age was linked to a 2.7 mg/dl increase in fasting glucose, and a 4.5 mg/dl increase in 2-hour post-prandial glucose levels.

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.
What Is Normal Fasting Blood Sugar And What Is A Diabetes Blood Sugar Level
The results of the fasting blood sugar test will come back as a number:
- 99 mg/dL or lower: This is a normal fasting blood sugar level.
- 100125 mg/dL: Fasting blood sugar in this range typically indicates prediabetes. This means your blood sugar levels are higher than normal but not high enough to be classified as diabetes.
- 126 mg/dL or above: This indicates high blood sugar, the main sign of diabetes.
If you have a high fasting blood sugar level, your healthcare provider may repeat the test to make sure. If the test reveals that you have prediabetes, your healthcare provider will recommend you repeat the fasting blood sugar test every year or two. The results will help you know whether you are progressing to Type 2 diabetes.

Enhancing Healthcare Team Outcomes
Routine screening of plasma glucose levels in at-risk patients would aid early diagnosis and intervention to limit the complications and mortality risks of diabetes. In particular, continuous monitoring of glucose in intensive care patients has been suggested to help prevent severe hyperglycemia and hypoglycemia and associated mortality risks. With continuous glucose monitoring , hypoglycemia or hyperglycemic episodes can be detected early and provide guidelines for rapid insulin/interventional adjustments. Hence, access to accurate measurements of glucose in real-time alerts health professionals to the efficacy of treatment and helps decrease the risk of missed episodes of hypoglycemia/hyperglycemia.
Serum glucose monitoring can inform and direct care for several potentially deleterious sequelae if elevated. As a result, it is the responsibility of everyone on the health care team to be involved in the testing, patient education, monitoring, and therapy when appropriate. This includes physicians, specialists, nurses , and pharmacists, such that everyone is on the same page and directing their efforts to optimize patient care and outcomes.
