Deficiency in insulin could lead to diabetes.
Insulin is a hormone produced by the pancreas that helps regulate the amount of glucose (sugar) in the blood. In people with diabetes, the pancreas either does not produce enough insulin or the body cannot effectively use the insulin that is produced.
When there is not enough insulin in the body, glucose builds up in the bloodstream instead of being absorbed by cells to provide energy. This can lead to high blood sugar levels, which can cause a range of health problems over time, including damage to the kidneys, nerves, eyes, and cardiovascular system.
Therefore, insulin plays a crucial role in regulating blood sugar levels, and a deficiency in insulin can lead to diabetes.
