Your Blood Sugar Levels Chart by Age: Are You in the Normal Range?
Understanding your blood sugar levels is crucial for maintaining good health, regardless of age. Blood sugar, or glucose, is the primary fuel for your body, and keeping it within a healthy range is essential for preventing long-term complications. This article provides a comprehensive overview of normal blood sugar levels by age, factors that can affect these levels, and what to do if your numbers are outside the target range.
What is Blood Sugar and Why Is It Important?
Blood sugar, also known as glucose, comes from the food you eat. After digestion, glucose enters your bloodstream and is used by your body for energy. Insulin, a hormone produced by the pancreas, helps glucose move from the blood into your cells.
Maintaining stable blood glucose levels is important because consistently high or low blood sugar can lead to serious health problems. High blood sugar (hyperglycemia) can damage blood vessels, nerves, and organs over time, leading to complications such as heart disease, kidney disease, and nerve damage. Low blood sugar (hypoglycemia) can cause dizziness, confusion, and even loss of consciousness if not treated promptly.

Understanding Blood Sugar Testing
There are several types of blood sugar tests that can help you monitor your blood glucose levels. The most common tests include:
- Fasting Blood Sugar (FBS) Test: This test measures your blood sugar after an overnight fast (at least 8 hours). It's often used to screen for prediabetes and diabetes.
- Random Blood Sugar Test: This test measures your blood sugar at any time of day, without fasting. It can be used to diagnose diabetes if symptoms are present.
- A1C Test: This test measures your average blood sugar levels over the past 2-3 months. It provides a longer-term view of blood sugar control and is used to diagnose and monitor diabetes.
- Oral Glucose Tolerance Test (OGTT): This test involves drinking a sugary drink and then having your blood sugar measured at regular intervals over a period of two hours. It is often used to diagnose gestational diabetes during pregnancy.

Factors That Can Affect Blood Sugar Levels
Many factors can influence your blood sugar levels, including:
- Diet: The types and amounts of food you eat play a significant role. Carbohydrates, in particular, have a direct impact on blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and burning glucose for energy.
- Medications: Certain medications, such as steroids and some antidepressants, can raise blood sugar levels. Diabetes medications can also affect blood sugar.
- Stress: Stress hormones, like cortisol and adrenaline, can raise blood sugar.
- Illness: When you're sick, your body may release hormones to fight the illness, which can raise blood sugar.
- Age: Blood sugar levels tend to increase with age as the body becomes less efficient at using insulin.
- Medical Conditions: Conditions such as Cushing's syndrome, polycystic ovary syndrome (PCOS), and pancreatic disorders can affect blood sugar levels.
