What is insulin?

Insulin is a hormone produced by the pancreas. It is vital in regulating blood sugar levels. Imagine insulin as the “key” which is used to open your cells, letting the glucose to go inside and be used as fuel. In the absence of the insulin the blood sugar doesn’t enter the cells leading to high levels of glucose in the blood.

How Insulin Works

when you eat something, the carbohydrate from your food is broken down into glucose and enters the blood stream. This glucose sends signals to pancreas to release insulin to help this insulin move into the cells. This glucose is either used by the cells or stored for the later use. Insulin also signals liver to store extra glucose in the form of glycogen for future use and this prevents blood sugar levels from rising too high.

What Happens When Insulin is Insufficient or Ineffective?

In people with type 1 the body doesn’t produce enough insulin while in type 2 diabetes the body becomes resistant to the insulin. Without insulin in the body or when body isn’t able to use it properly the glucose buildup in the blood leading to hyperglycemia. Over the time this hyperglycemia can cause serious complications, such as nerve damage, kidney disease, and cardiovascular problems.
