Blood sugar, also known as glucose, is the main type of sugar found in your blood. It comes from the food you eat, especially carbohydrates like bread, rice, and fruits. Your body uses insulin, a hormone produced by the pancreas, to help move glucose from your bloodstream into your cells, where it provides energy. Maintaining balanced blood sugar levels is important for overall health. If blood sugar levels are too high, it can lead to conditions like diabetes, while levels that are too low can cause symptoms like dizziness and fatigue. Eating a balanced diet and staying active can help keep your blood sugar stable.
