What Are Blood Sugar Levels

Blood Sugar Levels Chart | Includes fasting and after eating

Your blood sugar levels, also known as blood glucose levels, are a measurement that show how much glucose you have in your blood. Glucose is a sugar that you get from food and drink. Your blood sugar levels go up and down throughout the day and for people living with diabetes these changes are larger and happen more often than in people who don’t have diabetes.

Insulin And Blood Sugar

Insulin is an important hormone that helps regulate your blood sugar levels. The pancreas makes insulin. It helps control your blood sugar levels by assisting the cells that absorb sugar from the bloodstream.

If you have type 1 diabetes, your body doesnt make insulin. This means you have to inject insulin every day.

If diet and exercise arent enough to manage blood sugar, those with type 2 diabetes may be prescribed medications to help keep blood sugar levels within target ranges.

If you have type 2 diabetes, your body produces insulin, but may not use it properly or produce enough of it. Your cells dont respond to insulin, so more sugar keeps circulating in the blood.

Exercise can help the cells respond better and be more sensitive to insulin. The proper diet can also help you avoid spikes in blood sugar. This can help keep your pancreas functioning well since high blood sugar levels decrease pancreatic function.

Why You Should Measure Blood Sugar

As many as 1 in 3 adults in the US has prediabetes. This puts them at risk for developing type 2 diabetes. Among those, its also suspected that around 80% dont know they have it. Prediabetes often shows no symptoms at all for years.

This means that its important to get your blood glucose levels tested if you have any of the common for diabetes:

  • A family history of type 2 diabetes

  • Being older than 45

  • Having low levels of physical activity

If you fit into one or more of these categories, asking your health care provider for a simple blood test might help you avoid a lifetime of diabetes. It can also lower your risk for other conditions, such as heart disease, kidney conditions, eye problems, and stroke.

Its also crucial to keep track of blood sugar levels in diabetes to avoid serious complications of hypoglycemia and hyperglycemia:

  • , such as coronary artery disease with chest pain, heart attack, stroke, high blood pressure, and high cholesterol

Several Factors May Cause A Persons Postprandial Blood Sugar To Remain Elevated

Smoking after the meal: Studies show that smoking raises blood sugar levels in people with diabetes. Extreme stress: Stress produces the bodys fight-or-flight response triggering the release of stress hormones such as cortisol. These hormones cause the body to release the glucose it has previously stored for energy. Eating or drinking after the meal and before testing the blood sugar: Continuing to eat will keep blood sugars closer to their immediate post-meal levels.

Studies show that 15 to 20 minutes of moderate exercise, such as walking, shortly after a meal may improve glucose metabolism and reduce postprandial glucose levels.

What Are Normal Blood Sugar Levels

What Is Normal Blood Sugar?

You might want to measure your blood sugar before meals to get a baseline, and then two hours after your meal to measure your “normal blood sugar level”. Your doctor might also suggest measuring blood sugar before bed to be sure you have been eating well throughout the day and can go to sleep with peace of mind.

These are considered within the range of “normal” for blood sugar:

  • Less than 140 mg/dl if you do not have diabetes.
  • Less than 180 mg/dl if you have diabetes.

Why Your Blood Sugar Level May Be Low

If blood sugar drops below 70 mg/dL, it is below normal levels. This can be caused by a variety of factors, such as:

  • Not eating enough or missing a meal or snack
  • Reducing the amount of carbohydrates you normally eat
  • Alcohol consumption especially if youre drinking on an empty stomach
  • Taking too much insulin or oral diabetes medication based on carbohydrates or activity levels
  • Increased physical activity
  • Side effects from medications

If you have diabetes, keep your blood glucose meter and sources of fast-acting glucose close by in case your blood sugar drops. This is especially important for people with hypoglycemia unawareness, which is a condition that causes symptoms of low blood sugar to go unnoticed.

Eating balanced meals and snacks at regular times throughout the day is a big part of maintaining normal blood glucose levels.

Everyone will respond differently to certain factors, which is why its important to have individualized target glucose levels. To help you reach your target blood glucose goals, work with your healthcare provider to discuss modifications to your diet, physical activity, or medications, and alert them of other factors like a recent illness or stressful event.

Fasting Plasma Glucose Test

A fasting plasma glucose test is taken after at least eight hours of fasting and is therefore usually taken in the morning.

The NICE guidelines regard a fasting plasma glucose result of 5.5 to 6.9 mmol/l as putting someone at higher risk of developing type 2 diabetes, particularly when accompanied by other risk factors for type 2 diabetes.

What Are Blood Sugar Targets

Lower Blood Sugar After Eating Breakfast. Are Your Blood Glucose Levels Normal?

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.

Blood glucose is the sugar that is found in the blood. This sugar comes from the food we eat and this is the main source of energy for our bodies. Glucose can also be formed in the body and stored for later user. The blood carries this glucose to all the cells in the body to use it for energy.

Over time, if there is too much glucose in the blood, it can cause some serious health issues. Sometimes problems may arise if the sugar level is either too low or too high even without being a diabetic.

For People Without Diabetes

For people who dont have diabetes, an A1c test result lower than 5.7% is considered normal. If your level is between 5.7% and 6.4%, you may have what is sometimes called . This means that you have higher than normal blood glucose but dont meet the criteria to be diagnosed with diabetes.

An FPG test result of 99 mg/dL or lower means that youre within a safe range. A result between 100 to 125 mg/dL is in the prediabetes range, and you might need follow-up testing. A safe range for an OGT test result is around 140 mg/dL 2 hours after the test starts, while 140 mg/dL to 199 mg/dL is considered a prediabetic range.

If results suggest that you have prediabetes, your provider might order more tests and offer ideas for that can help bring your blood glucose levels down. The goal is tolower your risk of developing type 2 diabetes later in life, or to delay its onset as long as possible.

  • Blood sugar levels above 250mg/dL are considered very high. Therefore, it requires immediate medical treatment. In addition, it is recommended to have a ketones test done.
  • Blood glucose levels between 180 to250 mg/dL are considered high. Therefore, it may require insulin therapy and proper medication to control the high level.
  • Monitoring Blood Sugar In Older Adults

    Pin on Diabetic Me

    Monitoring blood sugar regularly is crucial to diabetes management. You check your blood sugar with a device called a glucometer.

    First, you prick a fingertip with a small needle called a lancet. Then you place a drop of blood on a test strip in the glucometer. After a few seconds, you’ll get a number.

    Generally, blood sugar should be checked before meals and at bedtime. Your healthcare provider may want you to check more or less often.

    The following chart outlines what blood sugar levels should be for older adults in the hours following a meal as well as when levels are either too high or too low.

    Level
    0-70 mg/dL 0-60 mg/dL

    Cognitive decline and chronic illnesses can make it hard to follow your diabetes care plan. That can happen even if you’ve successfully managed it for years.

    In these situations, your healthcare provider may:

    • Prescribe a lower dose of medication
    • Involve your caregivers in monitoring
    • Carefully watch you for low blood sugar

    Other Severe Symptoms Of Hyperglycaemia Include:

    • 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.

    What To Expect After Meals

    Food affects blood sugars, and most people who monitor their blood sugars notice their readings rise — and can be more challenging to control — after meals. If you do not have diabetes or prediabetes, your blood sugars may rise only slightly after meals — typically not exceeding 140 mg/dL when checked 2 hours after the start of a meal. If you have diabetes, ADA recommends post-meal blood sugars stay below 180 mg/dL. If your readings exceed this, you may be able to improve them. For instance, blood sugar can often be reduced by eating smaller meals, choosing healthful, high fiber foods, increasing physical activity, and by taking prescribed diabetes medications on time. If your readings are consistently above target, work with your doctor and diabetes care team to discuss solutions.

    When To See A Healthcare Provider

    If your test results reveal that you have type 1, type 2, or gestational diabetes, it is vital to speak to your doctor about establishing a comprehensive treatment plan.

    This plan should include diabetes self-management education and support services, as well as clear steps you can take to ensure that you are in the best state of health. However, if you have prediabetes or want to prevent diabetic issues, you should modify your lifestyle and avoid the outcome of the condition.

    Maintaining blood glucose levels within your target range is the main objective. Your doctor will specify your desired range. The type of diabetes, age, and presence of problems all affect the target level. For example, your blood sugar levels will be lower if you have gestational diabetes than in other forms of diabetes.

    As per research, physical exercise is crucial for managing diabetes. Find out from your doctor how many minutes you should exercise per week. Nutrition is also vital. You must also keep an eye on your cholesterol and blood pressure.

    Normal Blood Sugar Levels In Children With Diabetes According To Age

  • Children at the age of 6 should have blood glucose levels in the range of 80 to 200 mg/dL.
  • The sugar levels in children vary from the time they get up to the time they have taken their meals. Thus, regular monitoring of their normal blood sugar level is essential.
  • Especially if your child has complaints of hypoglycemia in the middle of the night, a blood sugar test is essential
  • For kids aged 6 to 12, the healthy range of blood sugar levels is between 80 to180 mg/dL. However, at this age, it is found that normal sugar reading increase after meals. Therefore, it is essential to limit their snack intake before sleep to ensure healthy blood glucose levels at bedtime.
  • For teens, healthy blood sugar levels are between 70 mg/dL to 150 mg/dL. Heredity could be one reason for irregular blood glucose levels in teens. The critical challenge in managing healthy blood sugar levels in teens is their stress, mood swing, and lifestyle issues, but regulating sugar levels in teens is possible through implanting good eating, sleeping habits, and other lifestyle modifications at the right age, which can be easily followed for life. A little Push and Motivation are all that is needed.
