What Is The Ideal Blood Sugar Reading

When Things Go Awry

When we eat food, the pancreas goes to work, releasing enzymes that help to break down food and hormones that help the body handle the influx of glucose. One of these hormones is insulin, and it plays a key role in managing glucose levels in the blood.

And here is where things can go wrong. If the pancreas doesnt make enough insulin or stops making it altogether, in the case of type 1 diabetes glucose levels in the blood can rise too high. Another scenario is that the pancreas makes enough insulin but the cells have trouble using it properly, causing blood glucose levels to rise. This is called insulin resistance and is the hallmark of type 2 diabetes.

In the short term, high blood glucose levels can make you feel downright bad. Thirst, frequent trips to the bathroom, fatigue and weight loss are all symptoms of high blood glucose . If not treated, more serious issues can occur, such as diabetic ketoacidosis. Chronic high blood glucose levels can lead to complications such as heart, kidney and eye disease, as well as nerve damage. So, its all about the blood glucose.

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

Do Your Blood Sugar Levels Drop When You Sleep

Yes, people with diabetes may experience a blood sugar level that drops when they sleep. This is largely due to a phenomenon called the dawn effect.

This doesn’t always happen and it’s not something that everyone experiences but as time goes on, our bodies will tell us which pattern is best for it: whether we should eat before bed or not. It’s important to experiment with what works best for our individual needs – if eating before bed causes our blood sugar to drop too low, then we’ll know that it’s best to avoid eating for the hours leading up to bed to keep your blood sugar under control.

If we do experience a drop in blood sugar levels, there are some strategies that may help us either prevent or treat it. Some people will take insulin before going to bed if they know their blood sugar is too high others might drink juice or eat cereal with milk before bedtime when they know they have low blood sugar during the night.

What Happens If Blood Sugar Level Is Too High

If your blood sugar levels are too high then you risk developing diabetes. You can develop cardiovascular disease and nerve damage. With diabetes, the glucose in your blood does not reach your cells and can lead to these and other complications. Adding exercise and eating healthy can help to control your diabetes and prevent secondary diseases.

You may develop diseases and disabilities in the future, such as cardiovascular disease and nerve damage, if you have diabetes.

If your blood sugar levels are high then you can develop diabetes and risk developing cardiovascular diseases and nerve damage. Doing exercise and eating healthy is important to control your diabetes and prevent secondary diseases.

Beyond Normal Goals: Whats An Optimal Glucose Level And Why Does It Matter

Exact numbers for what is considered optimal glucose levels to strive for while using CGM to achieve your best health are not definitively established this is a question that is individual-specific and should be discussed with your healthcare provider. With that said, research shows that there is an increased risk of health problems as fasting glucose increases, even if it stays within the normal range, making finding your optimal glucose levels all the more important.

While the International Diabetes Federation and other research studies have shown that a post-meal glucose spike should be less than 140 mg/dL in a nondiabetic individual, this does not determine what value for a post-meal glucose elevation is truly optimal for your health. All that number tells us is that in nondiabetics doing an oral glucose tolerance test, researchers found that these individuals rarely get above a glucose value of 140 mg/dL after meals.

So, while this number may represent a proposed upper limit of whats normal, it may not indicate what will serve you best from a health perspective. Many people may likely do better at lower post-meal glucose levels. Similarly, while the ADA states that a fasting glucose less than 100 mg/dL is normal, it does not indicate what value is optimal for health.

The following is a summary of insights from our review of research. You should consult with your doctor before setting any glucose targets or changing dietary and lifestyle habits.

Now That Youre Checking Your Blood Glucose What Do The Numbers Mean

Depending on your diabetes treatment plan, your doctor or diabetes educator may advise you to check once a week, once a day or up to 10 times a day . But what does it mean when you see a 67, 101 or 350 on your meter? And what is a normal blood sugar, anyway? Great questions! After all, if you dont know what the numbers on your meter mean, its hard to know how youre doing.

The American Diabetes Association provides guidelines for blood glucose goals for people with diabetes, and the goals vary depending on when youre checking your glucose:

Fasting and before meals: 80130 mg/dl

Postprandial : Less than 180 mg/dl

By the way, these guidelines are for non-pregnant adults with type 1 or type 2 diabetes. Children, adolescents and pregnant women may have different goals.

Your blood glucose goals may be different, however. If youre younger, have had diabetes for a shorter amount of time or are not taking any medicine for your diabetes, your glucose goals might be a little tighter, or lower. Likewise, your blood glucose goals may be higher than what ADA recommends if youre older, have diabetes complications, or dont get symptoms when your blood glucose is low.

Bottom line: talk with your health-care provider about the following:

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

*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

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:

What Are Abnormal Glucose Levels And Why Do They Matter

Why is it unhealthy for glucose levels to be too high or too low ?

Hyperglycemia refers to elevated blood glucose levels. This usually occurs because the body does not appropriately remove glucose from the blood this can happen due to many complex reasons. Elevated glucose levels can damage blood vessels and nerves over time this can then lead to problems in the eyes, kidneys, and heart, as well as numbness in the hands and feet. Very high levels can lead to coma and even death in some cases. People with fasting glucose levels higher than 100 mg/dl have impaired glucose tolerance and should speak with their healthcare provider.

Some people may think that to avoid all these issues, they should just keep their blood glucose levels as low as possible. If too high is bad, then low must be good, right? Not exactly. When glucose gets too low, its called hypoglycemia. The threshold for hypoglycemia is typically thought to be when glucose falls below 70 mg/dl. When this happens, the body may release epinephrine , the fight or flight hormone, which can lead to a fast heart rate, sweating, anxiety, blurry vision, and confusion, but also helps the body mobilize glucose into the blood. If blood glucose levels stay too low for too long, it can cause seizures, coma, and in very rare instances, death.

What Are Blood Sugar Targets

A blood sugar target is the range you try to reach as much as possible. These are typical targets:

• Before a meal: 80 to 130 mg/dL.
• Two hours after the start of a meal: Less than 180 mg/dL.

Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.

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.

Recommended Blood Sugar Targets

For people with type 1 diabetes, the American Diabetes Association recommends that blood sugar targets be based on a person’s needs and goals. Talk to your doctor and diabetes educator about these goals. A general guideline is:

Before meals, your blood sugar should be:

• From 90 to 130 mg/dL for adults
• From 90 to 130 mg/dL for children, 13 to 19 years old
• From 90 to 180 mg/dL for children, 6 to 12 years old
• From 100 to 180 mg/dL for children under 6 years old

After meals , your blood sugar should be:

• Less than 180 mg/dL for adults

At bedtime, your blood sugar should be:

• From 90 to 150 mg/dL for adults
• From 90 to 150 mg/dL for children, 13 to 19 years old
• From 100 to 180 mg/dL for children, 6 to 12 years old
• From 110 to 200 mg/dL for children under 6 years old

For people with type 2 diabetes, the American Diabetes Association also recommends that blood sugar targets be individualized. Talk to your doctor and diabetes educator about your goals.

In general, before meals, your blood sugar should be:

• From 70 to 130 mg/dL for adults

After meals , your blood sugar should be:

• Less than 180 mg/dL for adults

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.

Symptoms Of Blood Blood Sugar Levels

Symptoms of blood sugar levels differ depending on if it is high or low. To determine which way the blood sugar have moved, the symptoms for each are typically:

If symptoms are left untreated, more extreme circumstances can happen such as fainting, weakness, disorientation, vomiting and dehydration. When you notice symptoms, usually more than one at one time, it is advised to see a doctor right away.

It is important to get the right treatment so that you can return to a healthy normal blood sugar level and inhibit it from occurring again.

Treatment methods vary from the severity of the blood sugar level, whether it is high or low and if the patient has existing medical conditions, such as diabetes. Here are ways in which blood sugar levels can be treated:

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.

What Should I Do If My Blood Sugar Gets Too High

High blood sugar is also called hyperglycemia . It means that your blood sugar level is higher than your target level or over 180. Having high blood sugar levels over time can lead to long-term, serious health problems.

If you feel very tired, thirsty, have blurry vision, or need to pee more often, your blood sugar may be high.

Check your blood sugar and see if it is above your target level or over 180. If it is too high, one way to lower it is to drink a large glass of water and exercise by taking a brisk walk. Call your health care team if your blood sugar is high more than 3 times in 2 weeks and you dont know why.
