Blood sugar is significant in human body chemistry and it is an important diagnostic indicator for diabetes.
What Are Normal Blood Sugar Levels? The normal range is less than 100 mg/dL after not eating (fasting) for at least 8 hours; and less than 140 mg/dL 2 hours after eating.
What are high blood sugar (hyperglycemia) levels?
- Fasting hyperglycemia - This is blood sugar that's higher than 130 mg/dL (milligrams per deciliter) after not eating or drinking for at least 8 hours.
- Postprandial or after-meal hyperglycemia - This is blood sugar that's higher than 180 mg/dL 2 hours after you eat. People without diabetes rarely have blood sugar levels over 140 mg/dL after a meal, unless it’s really large.
In addition, Hemoglobin A1C ( HbA1C) is a blood test that provides an estimated average of blood sugar over the past 2-3 months. The testing result significance is indicated in the chart below, according to NIH –
Diagnosis A1C (percent) Fasting Plasma Glucose Oral glucose tolerance test
Normal below 5.7 99 or below 139 or below
Pre diabetes 5.7 - 6.4 100 to 125 140 to 199
Diabetes 6.5 or above 126 or above 200 or above
High blood sugar damages pancreas, kidneys, vision, nerves overtime and hardening blood vessels. Hypertension is more common in people with diabetes. Clinical Trials have shown that lowering BP reduces major cardiovascular events in those with diabetes. For cardiovascular and also renal protection, people with diabetes require good BP control and so most patients with diabetes and hypertension require combination therapy to achieve targets. Furthermore, NIH study shows connections between glucose metabolism, Alzheimer’s pathology, and symptoms.
More evidences from recent studies suggest that high blood sugar is associated with cognitive decline. Findings suggest that interventions that delay diabetes onset, as well as management strategies for blood sugar control, might help alleviate the progression of subsequent cognitive decline over the long-term.

Hyperglycemia treatment guidelines for 2025 from the American Diabetes Association (ADA) emphasize personalized care, prioritizing cardiovascular and kidney outcomes, and recommending new pharmacotherapies and technologies. Intensive behavioral modification interventions focusing on diet, weight reduction and increasing activity levels are successful in reducing weight and improving glycemic management while, at the same time, reducing the need for glucose-lowering and other medications.

The take home messages from your health coach
1. Making lifestyle modifications will regulate blood sugar naturally. It is an effective preventive strategy for risk reduction or work well in combination with medical interventions.
2. Blood sugar levels may increase with age as result of metabolic changes; therapeutic lifestyle changes will help to reduce cardiovascular and many other risks. Eat healthy, lose weight, and stay active are effective no-drug treatment.
