A general guideline for categorizing blood glucose levels based on severity using milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L):
Normal blood glucose: Fasting blood glucose levels between 70-99 mg/dL (3.9-5.5 mmol/L) are considered normal.
Hypoglycemia: Blood glucose levels below 70 mg/dL (3.9 mmol/L) are considered low and may indicate hypoglycemia (low blood sugar), which can cause symptoms such as shakiness, sweating, confusion, and fainting. Hypoglycemia can be caused by a variety of factors, including medications, excessive alcohol consumption, or medical conditions such as diabetes.
Hyperglycemia: Blood glucose levels above 126 mg/dL (7.0 mmol/L) are considered high and may indicate hyperglycemia (high blood sugar), which can cause symptoms such as increased thirst, frequent urination, blurred vision, and fatigue. Hyperglycemia can be caused by a variety of factors, including poor diet, lack of exercise, or medical conditions such as diabetes.
It's important to note that blood glucose levels may vary depending on the individual's age, health status, and other factors. Additionally, some medications and medical conditions may affect blood glucose levels. If you are concerned about your blood glucose levels or if you experience symptoms such as excessive thirst, frequent urination, or blurred vision, it's important to seek medical attention.
