What Is A Good Blood Sugar Number

Is Diabetes Diagnosed The Same Way In Every Country

There are four methods of diagnosing diabetes, which are used around the world. They are:

Diagnosing Prediabetes Type 2 And Type 1 Diabetes

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.

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.

What Is Blood Glucose Anyway

Blood glucose, or sugar, is sugar that is in your blood . It comes from the food that you eat foods that contain carbohydrate, such as bread, pasta and fruit are the main contributors to blood glucose. The cells in our bodies need glucose for energy and we all need energy to move, think, learn and breathe. The brain, which is the command center, uses about half of all the energy from glucose in the body.

How Do You Know What Your Blood Glucose Level Is

For the most part, you cant feel what your blood glucose level is unless its fairly high or its low. You may not even always have symptoms of either high or low blood glucose in fact, many people with type 2 diabetes dont have the usual symptoms of high blood glucose, and for this reason, its not uncommon for people to go undiagnosed for many years.

The best way to know your blood glucose level is to check it with a glucose meter. This means doing a fingerstick with a lancet and getting a drop of blood onto a test strip, then inserting the strip into the meter for a reading. Your doctor may be able to give you a meter free of charge, but youll likely need to pay for test strips and lancets. But check with your health plan, as there are likely one or two preferred meters that they want you to use.

Another way to know what your glucose levels are up to is to use a continuous glucose monitor, or CGM, which reads glucose in the interstitial fluid about every 5 minutes. Continuous glucose monitoring is expensive and may or may not be covered by your health plan.

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.

What You Can Drink With Meals

Add a low-calorie, low-sugar drink or choose water. Proper hydration is essential to helping your body remove excess sugar.

Some drinks that are good for keeping your blood sugar level low include:

• Unsweetened tea
• Unsweetened coffee
• Sparkling water or club soda
• Flavored water or sparkling water without added sugar
• Diet soda or other diet drinks

How To Save On The Freestyle Libre With Singlecare

If you dont have it yourself, you probably know at least one person living with diabetes. More than 30 million people in the U.S. alone have the condition. Which means youre likely familiar with the hassle of having to monitor glucose levels at all times. The process involves pricking your finger tip with a needle to test a drop of bloodouch!

When you have diabetes, its crucial to make sure its under control by testing your glucose levels often, based on your doctors recommendation. Luckily, for those who are sensitive to it or just tired of the repetition, there is an easier way: the Freestyle Libre, an FDA-approved glucose monitoring system that works as an alternative to the finger stick.

Symptoms Signs Causes Of Levels Of High Blood Sugar In The Blood

High blood sugar or hyperglycemia is an abnormally high blood sugar level in the blood. Hyperglycemia is a hallmark sign of diabetes and prediabetes.

Signs and symptoms of hyperglycemia include blurred vision, headaches, hunger, and …

The normal ranges for blood sugar levels in adults who do not have diabetes before eating or fasting the range begins at 72-99mg/dL while fasting ranges for those being treated for type 1 or type 2 diabetes range from 80 -130 mg/dL. According to the American Diabetes Association normal blood sugar levels before and after eating should be 80-130 mg/dL before eating a meal , and less than 180 mg/dL about 1-2 hours after eating a meal

High blood sugar ranges for people who dont have diabetes begins at 140 mg/dL or greater while for those being treated for diabetes, the high range begins at 180 mg/dL , called hypoglycemia.

A1c Goals Should Be Individualized

A1c goals should be individualized based on the individual capabilities, risks, and prior experiences, explains Gary Scheiner, MS, CDE, founder of Integrated Diabetes, and author of Think Like a Pancreas.

For example, we generally aim for very tight A1c levels during pregnancy and more conservative targets in young children and the elderly.

However, Scheiner highlights important factors that could justify aiming for a higher A1c, like hypoglycemia unawareness, which is described as when a person with diabetes no longer feels the oncoming warning signs of low blood sugar. This can put you at significant risk for severe low blood sugars resulting seizures or death. To reduce that risk, you would aim for higher target blood sugar ranges.

Someone with significant hypoglycemia unawareness and a history of severe lows should target higher blood glucose levels than someone who can detect and manage their lows more effectively, adds Scheiner. And certainly, someone who has been running A1cs in double digits for quite some time should not be targeting an A1c of 6% better to set modest, realistic, achievable goals.

Why Elevated Glucose May Lead To Weight Gain

According to an article published in the journal Diabetes, Metabolic Syndrome and Obesity and other research, high-glycemic carbs promote fat storage through their effect on insulin productionâespecially when carbohydrates and fats are eaten together. Elevated insulin levels result from both hypersecretion and hyperinsulinemia .

High insulin levels can occur both at baseline and after a meal. Even slightly elevated insulin levels past your normal promote fat storage and play a âkey roleâ in obesity for many.

High-glycemic foods result in quick spikes in glucose and insulin production as your body tries to return your blood glucose back to a normal level. Examples of high-glycemic foods include:

• White bread, bagels, white rice, pasta, white potatoes
• Muffins, croissants, doughnuts, flavored instant oatmeal, most cereals
• Cakes, candy, cookies, most desserts
• Corn

When your glucose spikes and you donât burn the excess energy, your body converts the extra glucose to glycogen that gets stored in your muscle tissue and liver and, with the help of insulin, gets converted into fat stored in your adipose cells. Meanwhile, the fat that you ate at the same time is pushed straight into fat cells, since your body loves to burn carbohydrates for quick energy.

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.

What Should My Blood Sugar Levels Be

Your blood sugar level changes depending on what you’ve eaten, whether you’ve exercised and other factors but we have some general guidelines to determine what levels are healthy.

For generally healthy individuals who haven’t eaten for eight hours or more, a normal blood sugar level is between 70-99 mg/dL. When you’ve eaten in the past two hours, it should be no higher than 140 mg/dL. To refresh your chemistry knowledge, that unit is milligrams per deciliter and it’s measuring the amount of glucose present in your blood.

Only a medical professional can diagnose diabetes or another issue with your blood sugar, so if you’re concerned about your blood sugar levels, check with a doctor.

Take Things One Day At A Time

While you can understand how diabetes works on an intellectual level, the reality is that things can sometimes happen that feel out of your control. This can be a very stressful and scary time for the child but also for the parent, McCrudden says. The needles can be painful or anxiety-inducing at first. Or, maybe your child is embarrassed about dealing with the condition in front of other kids or feels like a burden.

Diabetes management is a balancing act, says Lisa Goldsmith, of Natick, Massachusetts, whose daughter was diagnosed at 7. You can do everything right and still get high or low blood sugars. It is not an exact science and you will not ever have perfection. But you will figure out a routine and develop a new normal. The more you all adjust to the condition, the more good days you will have.

Levels After Youve Eaten

Many foods have types of carbohydrates called starches and sugars. When you eat foods with these types of carbohydrates, your body breaks them down into glucose, which is a type of simple sugar, and releases the glucose into your bloodstream. Aside from glucose produced by your liver, food is the main source of plasma glucose.

Two hours after eating, your blood sugar levels rise. They rise more when you eat more carbohydrates, when you do not eat fiber, fat, or protein with your carbs, and when you eat certain types of carbohydrates, such as refined sugars and starches.

These are target values from The Joslin Diabetes Center, which include levels for people with diabetes:

Can I Check My Own Blood Sugar

You can do blood sugar level check by doing a finger-prick test, by using a blood sugar monitor called a flash glucose monitor or with a continuous glucose monitor . You can do this several times a day helping you keep an eye on your levels as you go about your life and help you work out what to eat and how much medication to take. Find out your ideal target range.

Not everyone with diabetes needs to check their levels like this. Youll need to if you take certain diabetes medication. Always talk to your healthcare team if youre not sure whether thats you theyll give you advice on whether to check them yourself and how often.

And theres also something called an HbA1c, which is a blood test to measure your average blood sugar level over the last three months. Everyone with diabetes is entitled to this check.

High blood sugar levels increase your risk of developing serious complications. However you manage your diabetes, stay in the know about your blood sugar levels

How Do I Check My Blood Sugar

You use a blood glucose meter to check your blood sugar. This device uses a small drop of blood from your finger to measure your blood sugar level. You can get the meter and supplies in a drug store or by mail.

Read the directions that come with your meter to learn how to check your blood sugar. Your health care team also can show you how to use your meter. Write the date, time, and result of the test in your blood sugar record. Take your blood sugar record and meter to each visit and talk about your results with your health care team.

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

Make A Note Of Your Readings

It may sound obvious, but you must record your readings. Note them down in a diary, a notebook or in your phone calendar. Some meters have software that lets you do this. You could try a diabetes app too.

You and your healthcare team can then look back over your results to see if you need to adjust your treatment.
