Normal Blood Sugar Levels for Adults: A Complete Chart by Age

Understanding normal blood sugar levels is crucial for maintaining good health and preventing diabetes. This article provides a complete chart of blood sugar ranges for adults, categorized by age, and explains what these numbers mean for your overall well-being. We’ll also discuss factors that can influence blood glucose levels and offer tips for maintaining a healthy range.

What is Blood Sugar and Why Does It Matter?

Blood sugar, or glucose, is the main source of energy for our bodies. It comes from the food we eat and is transported through the bloodstream to cells throughout the body. Insulin, a hormone produced by the pancreas, helps glucose enter the cells to be used for energy.

Maintaining stable blood sugar levels is vital because consistently high or low levels can lead to serious health problems. High blood sugar (hyperglycemia) can damage organs over time, leading to complications such as heart disease, kidney disease, nerve damage (neuropathy), and vision problems. Low blood sugar (hypoglycemia) can cause dizziness, confusion, and even loss of consciousness.

Normal Blood Sugar Ranges for Adults

The following chart outlines the general normal blood sugar ranges for adults without diabetes, as recommended by medical professionals. Keep in mind that individual results may vary, and it's essential to consult with a healthcare provider for personalized advice. These numbers typically refer to blood sugar levels measured after fasting (at least 8 hours without eating) and two hours after eating a meal.

Age Group	Fasting Blood Sugar (mg/dL)	2-Hour Postprandial (After Eating) Blood Sugar (mg/dL)	HbA1c
Adults (Under 60)	70-100	Less than 140	Less than 5.7%
Adults (60 and Older)	80-110	Less than 160	Less than 6.5%

Fasting Blood Sugar: This is the blood sugar level measured after an overnight fast (typically 8-12 hours). It provides a baseline measure of how well the body is regulating blood glucose when not actively processing food.
2-Hour Postprandial: This refers to the blood sugar level measured two hours after starting a meal. It indicates how effectively the body processes glucose from food.
HbA1c: Also known as glycated hemoglobin, the A1c test reflects your average blood sugar levels over the past 2-3 months.

Note: These ranges are general guidelines. Optimal blood sugar targets can vary based on individual factors such as overall health, medications, and other medical conditions.

Blood Sugar Levels for People with Diabetes

For individuals with diabetes, target blood sugar ranges are typically different than those without diabetes. The American Diabetes Association (ADA) recommends the following general targets:

Fasting Blood Sugar: 80-130 mg/dL
2-Hour Postprandial: Less than 180 mg/dL
HbA1c: Less than 7.0%

It's crucial for people with diabetes to work closely with their healthcare team to establish individualized blood sugar goals and a management plan tailored to their specific needs. This often involves regular blood glucose monitoring, medication adjustments, and lifestyle modifications.

Factors That Can Affect Blood Sugar Levels

Several factors can influence blood sugar levels, including:

Diet: The type and amount of food consumed play a significant role. Carbohydrates, in particular, have a direct impact on blood glucose levels.
Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and using glucose for energy.
Stress: Stress hormones can raise blood sugar levels.
Illness: Being sick can also elevate blood sugar.
Medications: Certain medications, such as steroids, can affect blood glucose levels.
Age: As we age, our bodies may become less efficient at regulating blood sugar, leading to higher fasting and postprandial levels.
Hydration: Dehydration can affect blood sugar concentration.
