Blood glucose, also known as blood sugar, refers to the concentration of glucose (a type of sugar) present in the bloodstream. Glucose is a crucial source of energy for the cells in the body, particularly for the brain. It comes from the food we eat, especially carbohydrates.

When you consume carbohydrates, they are broken down into glucose during digestion. This glucose is then absorbed into the bloodstream, causing an increase in blood glucose levels. The body’s cells, including those in muscles and organs, use this glucose for energy.

To regulate blood glucose levels and ensure they stay within a normal range, the pancreas releases insulin. Insulin is a hormone that helps cells absorb glucose from the bloodstream. When there’s an excess of glucose, insulin facilitates its storage in the liver for later use.

Maintaining proper blood glucose levels is essential for overall health. Abnormalities in blood glucose levels can lead to various health issues, including diabetes. Diabetes is a condition characterized by either insufficient insulin production or the body’s inability to effectively use the insulin it produces. There are different types of diabetes, including type 1 diabetes, type 2 diabetes, and gestational diabetes.

Regular monitoring of blood glucose levels is crucial for individuals with diabetes to manage their condition effectively. This is often done using a glucose meter, which measures the amount of glucose in a small sample of blood, usually obtained through a fingerstick. The results help individuals make informed decisions about diet, medication, and other aspects of their diabetes management.
