What is normal blood sugar by age?

If you have diabetes, simple blood sugar control is critical for maintaining optimal health and avoiding long-term health issues.

Blood sugar levels can also be used to determine your risk of developing diabetes. For instance, individuals with prediabetes will have their blood sugar levels checked annually, as elevated blood sugar levels can suggest an increased risk of developing diabetes(blood sugar by age).

Diabetes type 2

Here’s everything you need to know about how blood sugar is checked, what constitutes normal, and how to adjust blood sugar levels if they are abnormally high or low.

How is blood sugar defined?

The term “blood sugar” or “blood glucose” refers to the amount of glucose in your blood.

When you consume carbohydrates, your body converts them to glucose. This becomes your body’s primary source of energy, powering essential systems such as the brain, heart, liver, and muscles.

Without diabetes, the pancreas produces insulin to aid cells in absorbing glucose and fueling the body. However, in persons with diabetes, the body either does not generate enough insulin or does not operate well, necessitating strict control of blood sugar levels to avoid health consequences.

How to take blood sugar readings

There are two primary methods for monitoring your blood sugar levels:

  • Test of blood glucose. Numerous at-home blood sugar monitoring devices are available, such as finger-prick monitoring kits or continuous glucose monitors.
  • A1C testing. A1C is a blood test that your doctor performs to determine your average blood sugar levels over the previous three months.
  • Type 1 diabetics and some type 2 diabetics must check their blood sugar at least four times daily, according to Mathioudakis. This should typically be done before a meal, one to two hours after, and before night.
  • The timing of these measures can aid in determining the appropriate dose of insulin to employ. For instance, it may be necessary to increase insulin use following a high-sugar meal or avoid hypoglycemia while sleeping.

You should check your blood sugar at home using blood glucose tests such as a glucose metre or continuous glucose monitor (CGM). Both devices test blood sugar in milligrams per deciliter or mg/dL.

If you do not have diabetes but are at risk. Your doctor may request that you undergo an A1C test during your annual check-up. This test provides data in the form of a percentage; the more significant the percentage, the higher your blood sugar level was in the preceding three months. Individuals with diabetes should have their A1C levels checked at least twice a year, maybe every three months(blood sugar by age).

What is a healthy individual’s typical blood glucose level?

Blood sugar levels can be expected, elevated, or depressed, depending on the amount of glucose in a person’s bloodstream. Glucose is an essential sugar that is constantly present in the bloodstream. Normal blood glucose levels can be determined while fasting, eating, or shortly after eating. For adults without diabetes who have not eaten in at least eight hours (fasting), an average blood glucose level is less than 100 mg/dL. Two hours after eating, an adult without diabetes should have a 90 to 110 mg/dL.

Numerous factors during the day affect blood sugar levels

  • The type of food consumed, the quantity consumed, and the period during which it was consumed
  • Physical exertion
  • Medication
  • Medical problems
  • Age
  • Stress
  • Dehydration
  • Illness
  • Menstrual cycles
  • Alcohol

For everyone without diabetes or prediabetes, regardless of age, an optimum blood sugar level in the morning should be less than 100 mg/dL. However, remember that blood sugar levels can change during the day due to the variables described previously.

Children under the age of six years should have daily blood glucose levels of approximately 80 to 200 mg/dL. This range is considered healthy. And the amount of glucose in a child’s blood will change throughout the day. From when they wake up to when they eat and again before bedtime. As a result, children with diabetes or hypoglycemic episodes may require their parents to check their blood sugar levels in the middle of the night.

Children’s Blood Sugar Level

Blood sugar levels in children aged 6 to 12 should range between 80 and 180 mg/dL throughout the day. Following a meal, blood sugar levels rise as the body converts carbs to glucose, subsequently transported throughout the bloodstream. To prevent a child’s blood sugar from getting too high before bedtime, particularly if the youngster has diabetes, try restricting foods before bed.

Teenager’s Blood Sugar Level

Teenagers should maintain an average blood sugar level between 70 and 150 mg/dL throughout the day. Teenage years are frequently the most challenging for adolescents with diabetes, as diabetes management needs a level of responsibility and behaviour control that is uncommon in most teenagers. Therefore, teenagers should strive to maintain blood sugar levels between 70 to 150 mg/dL throughout the day by monitoring their diet, exercising, and taking their diabetic medications, if they have any.

Adults Blood Sugar Level

Adults aged 20 years or older typically have blood sugar levels between 100 to 180 mg/dL throughout the day. Therefore, when you awaken in the morning, your fasting blood sugar level should be the lowest it has been in approximately eight hours. If you are an adult with difficulty controlling your blood sugar, your healthcare provider can help you develop a treatment plan to manage it more effectively.

Blood glucose levels outside the ranges mentioned above are classified as either high or low blood sugar. Blood sugar levels are deemed high if they exceed 130 mg/dL before a meal or 180 mg/dL one to two hours afterward. Many people do not experience symptoms of hyperglycemia until their blood sugar level reaches 250 mg/dL or higher. The maximum blood sugar level considered safe varies according to the individual and whether they have diabetes, but it is generally between 160 and 240 mg/dL.
