Insulin is one of the vital hormones in our body and has various functions. When we consume carbohydrates, it gets broken down by the body into glucose. Insulin helps in proper utilization of glucose for energy or storing purposes. This hormone is produced by the beta cells present in the pancreas. Insulin plays a major role in ensuring that the blood sugar levels are not too high – hyperglycemia or too low – hypoglycemia. It is very important for our cells to get energy from glucose, so after we have a meal, sugar levels in our blood rises. To make sure that the cells are not overloaded, the pancreas produces insulin. If the pancreas does not produce enough insulin, chances are that one can be at a higher risk of diabetes. There are many different roles that insulin plays in our body, which are mentioned below.
Creates and Distributes Energy
When our food breaks down into sugars, it needs a medium by which it can reach out to the entire body and enter the cell directly, this is possible because of insulin. Insulin is key to making sure that the cells carry out the glucose required in the body so that it can be used up as energy to keep us going throughout the day.
Balances Blood Sugar
Insulin ensures that our blood cells are carrying the right amount of glucose. Too much or too little can cause serious condition. It helps my making sure that cells are not overloaded with glucose/sugar. This helps in balancing blood sugar levels in the body.
How does insulin make sure that the blood is not carrying too much sugar/glucose? Insulin sends a signal to the liver to store excess glucose in the bloodstream that can be used later.
Muscles and Fat Storage
Another way insulin carries out the function of storing glucose is by directing the muscle and fat cells to store excess glucose in blood.
Keeps Cells Healthy
It is very important for our cells to be healthy as they carry out our day-to-day function. Insulin makes sure that the cells are not starved for energy. When cells are starved for energy, they look for an energy source elsewhere which could lead to unhealthy complications.
Insulin helps use glucose for energy, without which the body begins to burn fats to use as energy instead that could lead to high levels of toxic ketones. To make sure that does not happen, insulin is required in the body.
