Blood sugar levels refer to the amount of glucose in your bloodstream, which is crucial for providing energy to your body’s cells. The body regulates blood sugar levels through insulin, a hormone produced by the pancreas.
Normal blood sugar levels for a healthy adult are:
Fasting (no food for 8 hours): 70–99 mg/dL
Post-meal (2 hours after eating): Less than 140 mg/dL
Random blood sugar (any time of day): Less than 200 mg/dL
High blood sugar (hyperglycemia) can occur in diabetes, leading to long-term complications such as heart disease, nerve damage, and kidney problems. Low blood sugar (hypoglycemia) can cause dizziness, confusion, or even loss of consciousness. Regular monitoring and maintaining balanced blood sugar through diet, exercise, and medication are essential for managing health.
