What is the need of insulin and why insulin controls sugar level and if sugar level is not control what happens
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).
The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy.
Sugar control has been shown to be very important in helping prevent particular diseases, especially if you have diabetes. In the long term, poor control of blood sugar levels in diabetic patients leads to both heart and blood vessel disease, kidney failure, nerve damage, eye problems and heart disease.
