Understanding Normal Blood Sugar Levels: An All-Ages Comprehensive Guide Maintaining healthy blood sugar levels is a huge step towards good health on your part. Blood sugar, or glucose, is the most important source of fuel for the human body that forms the base of general well-being, and keeping adequate sugar in the blood would prevent varied chronic conditions like diabetes and promote an overall healthy lifestyle altogether.
What Are Normal Blood Sugar Levels?
Blood sugar may vary with age and hour of the day. Below is a general guideline of normal blood sugar levels within different age categories:
| Age Group | Fasting Blood Sugar (mg/dL) | 1-2 Hours After Eating (mg/dL) |
| Children under 6 years | 80–180 | Up to 180 |
| Children 6–12 years | 80–180 | Up to 140 |
| Teens 13–19 years | 70–150 | Up to 140 |
| Adults 20 years and above | Less than 100 | Less than 180 |
| Seniors 65 years and above | 70–130 | Less than 180 |
Why is blood glucose level different at every age?
Physiological changes, such as metabolic rate, hormonal change, and general level of activity, differs at every stage of life and thus affects glucose control. For example:
Children and Adolescents: Their metabolic rate is higher, and the level of blood glucose concentration required for growth and energy is highly increased.
Adult: Immature range becomes stable, however, an unhealthy diet and sedentary lifestyle would eventually turn into an imbalance of glucose.
Older people are mainly associated with higher blood sugar, the risk which arises due to lesser sensitivity towards insulin.
It is quite a significant milestone to go to see your doctor, or your health care practitioner, and work out what normal is for you, especially with risk factors like family history and conditions one already has.
Gender Differences in Blood Sugar Levels
Even though the normal range of blood sugars is the same for both men and women, in specific conditions, a woman’s sugar might call for more particular attention as discussed below.
- Hormonal Changes. Menstruation, pregnancy, and menopause are all causes that can affect the glucose levels.
- Gestational Diabetes: This is a form of diabetes that begins during pregnancy and must be monitored.
- Changes after Menopause: Hormones can cause higher resistance to insulin.
Women need to monitor their sugar levels more frequently in these two stages of life to avoid any unwanted complications.
Understanding Blood Sugar Testing
Testing often is a way of knowing and controlling the blood sugar levels. There are two common ones;
- Fasting Blood Sugar Test: Glucose after fasting overnight. Normal level is less than 100 mg/dL.
- Postprandial Blood Glucose Test: Measuring glucose 1 to 2 hours after meals is usually below 180 mg/dL in most adults.
The doctor may also request more tests from the patient with diabetes or prediabetes. Such tests include A1C tests which show the average level of blood glucose in the last three months.
Signs of High and Low Blood Sugar
Hyperglycemia- High Blood Sugar
- Drink excessively and pass too much water.
- Feeling fatigued or has a headache.
- Blurry eyesight.
- Lengthy period of healing wounds.
Hypoglycemia- Low Blood Sugar
- Tremors or dizziness.
- Sweat.
- Incomprehensibility or becomes restless.
- Panic heartbeat.
Both are medical conditions that should not go untreated; otherwise, complications may arise.
