Chart of Normal Blood Sugar Levels for Adults with Diabetes Age Wise

Our body maintains a level of blood glucose for body metabolism. The normal blood glucose levels in a healthy body are between 90 to 100 mg/dL. But sometimes, these blood glucose levels may go high or low. Such high or low blood glucose levels are signs of health conditions requiring medical attention.

Why Blood Glucose Levels Rise in Diabetes?

The food we eat is converted to glucose and released into the bloodstream. Therefore, blood glucose levels (blood sugar levels) are high after eating. As does the glucose generates, the body signals the pancreas to release insulin.

Insulin helps in the absorption of blood glucose by the body cells. As a result, the glucose from the blood is absorbed, and its level in the blood becomes normal again. Thus, together insulin and cell absorption helps in regulating blood glucose levels.

But in the case of diabetes, the body becomes insulin resistant, or there is insulin deficiency. Due to which the cell absorption of the blood glucose decreases. As a result, high blood glucose levels cause Diabetes. Over time, such high blood glucose levels can cause damage to nerves, kidneys, eyes, and heart.

Therefore if you have diabetes, it is essential to keep your blood glucose levels to some typical acceptable values. To help you understand blood glucose levels, a blood sugar level chart is the best option.

Normal Blood Glucose 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 (male or female) 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. The major factors for such change in the blood glucose levels are as follows:

  1. The type of food can impact blood sugar levels. For example, if you eat rich carb food, high-calorie food, the blood sugar levels may be high.
  2. The quantity of food. A high amount of food may increase blood sugar levels.
  3. Physical activities impact blood sugar levels. For example, heavy and rigorous work may decrease blood sugar levels, whereas no or less physical activity may increase blood sugar levels.
  4. Certain medicines change blood sugar levels.
  5. Medical conditions like hypoglycemia, diabetes, liver disease may cause changes in blood sugar levels.
  6. Alcohol consumption.
  7. Age and stress
  8. Dehydration. It can cause low blood glucose levels.
