Fasting Blood Glucose Level Test Preparation
What should you do if your doctor orders a fasting blood sugar test? The preparation is the same as when you take a fasting test for cholesterol. First, be sure to find out if you need to schedule an appointment for your test . Ask your doctor what time is best to take it.
Then:
- Schedule your test if necessary
- Ask your doctor if you need to change any of the medications you take on the morning of the test
- If you normally drink coffee or have caffeine, ask your doctor if that is okay. It may not be, since it affects blood sugar levels
- Fast for at least 8 hours before your test. Usually, an overnight fast is most convenient
- You can drink water
What Is The A1c Test
The A1C test is a simple blood test that measures your average blood sugar levels over the past 2 or 3 months. The test is done at a lab or your doctors office in addition tonot instead ofregular blood sugar testing you do yourself.
A1C testing is part of the ABCs of diabetesimportant steps you can take to prevent or delay health complications down the road:
- A: Get a regular A1C test.
- B: Try to keep your blood pressure below 140/90 mm Hg .
- C: Manage your cholesterol levels.
- s: Stop smoking or dont start.
The A1C goal for most adults with diabetes is between 7% and 8%, but your goal may be different depending on your age, other health conditions, medicines youre taking, and other factors. Work with your doctor to establish a personal A1C goal for you.
When To Call Your Healthcare Provider
A hypertensive crisisdefined as blood pressure above 180/120 mm Hgrequires immediate medical attention. Call 911 if you are also experiencing symptoms such as chest pain, back pain, shortness of breath, difficulty speaking, a change in vision, weakness, or numbness.

What Are Normal Blood Glucose Levels
This article is not just for older people. We also want to look at the ideal blood glucose level and learn about the average glucose level by age so that you have a better understanding of what your blood glucose level should be. These are just guidelines, so please consult with a doctor if you have any questions.
Average Blood Pressure By Age
As you get older, your blood vessels tend to become stiffer and plaque can build up in them, which can raise your blood pressure. If your blood pressure becomes too high, you’re at a greater risk for heart disease, strokes, and more.
In 2015, the average blood pressure worldwide was 127/79 mm Hg in men, and 122/77 mm Hg in women, according to a study analysis published in Lancet.
When researchers for the National Center for Health Statistics looked at average blood pressure in U.S. adults between 2001 and 2008, the average reading was 122/71 mm Hg. The breakout was 124/72 mm Hg for men, and 121/70 mm Hg in women. It rose by age and was significantly higher in Black people.
The researchers found the following breakdown by age, sex, and race or ethnicity:

How To Measure Blood Sugar Levels
There are two main ways to check your blood sugar levels:
Type 1 diabetics, along with some type 2 diabetics, who require insulin medication, must check their blood sugar at least four times per day, says Mathioudakis. Typically, this should be done before a meal, one to two hours after a meal, and at bedtime.
The timing of these measurements can help determine how much insulin to use. For example, it can be important to use more insulin after a high-sugar meal, or to avoid falling into hypoglycemia while you’re sleeping.
To check your blood sugar at home, you should use blood glucose tests, such as a glucose meter or continuous glucose monitor . Both devices measure blood sugar with the unit mg/dL, which means a milligram of sugar per deciliter of blood.
If you don’t have diabetes, but you may be at risk, your doctor might have you take an A1C test during a yearly check-up. This test reports results as a percentage the higher the percentage, the higher your blood sugar has been in the past three months. Those with diabetes should get an A1C test at least twice a year and sometimes every three months.
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

People With Gestational Diabetes
Gestational diabetes can occur during pregnancy. Often, it is a temporary condition, but it can lead to pregnancy complications.
The American Diabetes Association recommends that people with a diagnosis of gestational diabetes aim for blood sugar levels similar to those for people without diabetes, although individual targets may vary.
The ADA offers the following as a guideline:
| Blood sugar level |
- kidneys
- blood vessels
A wide range of complications can also result, such as slow wound healing and frequent infections. Other possible complications include:
Other Severe Symptoms Of Hyperglycaemia Include:
- Nerve damage
- Kidney damage
- Blood vessel damage
Mild hyperglycaemia, depending on the cause, will not typically require medical treatment. Most people with this condition can lower their blood sugar levels sufficiently through dietary and lifestyle changes.
Those with type 1 diabetes will require the administration of insulin , while those with type 2 diabetes will often use a combination of injectable and oral medications , although some may also require insulin.

Official Hba1c Ada Recommendation For Someone With Diabetes
The American Diabetes Association recommends an HbA1C of less than 7% for most nonpregnant adults with diabetes. A lower goal, such as less than 6.5%, may be appropriate for some people who have had diabetes for a shorter amount of time, for younger people, for those without heart disease, and/or for those with type 2 diabetes treated with lifestyle or metformin only. A higher HbA1C goal, such as less than 8%, may be appropriate for people with a history of severe hypoglycemia, a limited life expectancy, advanced diabetes complications, other illnesses, or for whom a lower HbA1C goal is difficult to achieve. Its important that people with diabetes discuss their target blood sugar goals with their healthcare provider.
HbA1C levels should be checked between two to four times per year in people who have diabetes.

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.
High And Low Blood Sugar Levels In Diabetes
The chart below shows the concerning values of blood sugar levels for diabetic patients. Red levels are indicators that require emergency treatment, while yellow levels indicate medical attention but not an emergency.

Blood Sugar Chart: Summary
The fasting blood sugar, 2-hour post-meal blood sugar, and HbA1C tests are important ways to diagnose prediabetes and diabetes, as well as indicate how well a persons diabetes is being managed. If you think you have diabetes, its important to not try and diagnose yourself by doing a finger-stick with a home blood glucose meter. There are strict standards and procedures that laboratories use for diagnosing diabetes therefore, you should get tested at your doctors office or at a laboratory.
Its also important to talk with your doctor to make sure you understand a) how often you should have certain tests, such as a fasting blood glucose or HbA1C test b) what your results mean and c) what your blood sugar and HbA1C targets are.
If you have not been previously diagnosed with prediabetes or diabetes but your results are above normal, your doctor may recommend other tests and should discuss a plan of treatment with you. Treatment may include lifestyle changes, such as weight loss, a healthy eating plan, and regular physical activity. You may need to start taking diabetes medications, including insulin. If you are diagnosed with diabetes, its recommended that you learn how to check your blood sugars with a meter so that you and your healthcare team can determine how your treatment plan is working for you.
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.

Normal Blood Sugar Levels After Eating For Diabetics
The American Diabetes Association recommends that the blood sugar 1 to 2 hours after the beginning of a meal be less than 180 mg/dl for most nonpregnant adults with diabetes. This is typically the peak, or highest, blood sugar level in someone with diabetes. Again, this target may need to be individualized for certain people based on such factors as duration of diabetes, age and life expectancy, cognitive status, other health conditions, cardiovascular complications, and hypoglycemia unawareness. Its important that people with diabetes discuss their target blood sugar goals with their healthcare provider.
What Is Diabetic Ketoacidosis
If you think you may have low blood sugar, check it even if you dont have symptoms.
When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:
- Fast, deep breathing.
- Nausea and vomiting.
- Stomach pain.
If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, . DKA requires treatment in a hospital.
DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who havent yet been diagnosed. People with type 2 diabetes can also develop DKA, but its less common.

Normal and diabetic blood sugar ranges
For most healthy people, normal blood sugar levels are as follows:
- However, When you are fasting, your blood sugar range between 4.0 to 5.4 mmol / L
- And, 2 hours after eating up to 7.8 mmol / L
For people with diabetes, the targets for blood sugar levels are as follows:
Before meals: 4 to 7 mm / L in people with type 1 or type 2 diabetes
After meals: Under 9 mm / L for type 1 diabetes and less than 8.5 mm / L for type 2 diabetes.
What Are The Complications Of Low Blood Glucose
Mild-to-moderate low blood glucose can be easily treated. But severely low blood glucose can cause serious complications, including passing out, coma, or death.
Repeated episodes of low blood glucose can lead to
- high blood glucose levels, if worry or fear of low blood glucose keeps you from taking the medicines you need to manage your diabetes8
- hypoglycemia unawareness, a condition in which you dont notice any symptoms of low blood glucose until your blood glucose level has dropped very low
