In general, a fasting blood glucose level of 63 mg/dL is below the normal range and may indicate hypoglycemia.
The normal fasting blood glucose level for adults should be between 70-99 mg/dL. Levels below this range are considered hypoglycemia and may cause symptoms such as dizziness, sweating, and palpitations. However, occasional mild decreases may be related to diet, exercise, or certain medications and are usually not a cause for concern. It is recommended to immediately consume sugary foods, such as candy, chocolate, or fruit juice. Additionally, seeking timely medical evaluation is advised to rule out other conditions such as abnormal insulin secretion or insulinoma.
It is important to maintain regular eating habits, keeping consistent meal times each day and avoiding prolonged fasting. Eating small, frequent meals—5 to 6 times daily, with intervals of 3 to 4 hours—can help maintain balanced nutrition. If you are prone to hypoglycemia, regular blood glucose monitoring is recommended, especially after dietary or medication adjustments, to track changes in blood sugar levels and better manage your lifestyle.
