Insulin - a hormone that regulates blood glucose levels and is used in the diagnosis and monitoring of diabetes.
Insulin is a hormone responsible for regulating blood sugar levels in the human body. It is produced in the pancreas and helps move sugar from the blood into the cells, where it can be used as an energy source. In this blog post, I would like to explain how insulin works and why it is important for people with diabetes.
Blood glucose level is the concentration of glucose (sugar) in the blood. Glucose is the main source of energy for the body's cells and is obtained from the food we eat. After a meal, blood glucose levels rise because glucose enters the blood. To lower and stabilise the blood sugar level, the pancreas secretes insulin. Insulin is like a key that fits onto special receptors on the surface of the cells and makes them permeable to glucose. This allows the glucose from the blood to enter the cells and be burned or stored there.
In people with diabetes, the blood glucose level is too high because either too little or no insulin is produced (type 1 diabetes) or because the cells, no longer respond properly to insulin (type 2 diabetes). This means that glucose no longer reaches the cells sufficiently and accumulates in the blood. This can lead to various health problems, such as damage to the nerves, eyes or kidneys.
Insulin is therefore a vital hormone that regulates blood sugar and provides us with energy.
