Be taught extra: What Are Regular Blood Sugar Ranges?
What’s blood sugar?
Blood sugar, additionally known as blood glucose, is the sugar present in your blood. Such a sugar is the primary supply of power, or gas, for the physique. It’s additionally the first supply of power for the mind.
Whenever you eat, the physique breaks down the carbohydrate (carb) in meals into glucose, which then is launched into the bloodstream. As glucose ranges within the blood start to rise, the pancreas releases insulin, a hormone, to maneuver glucose into cells for use for power.

In individuals who don’t have diabetes, blood sugar ranges are very tightly managed within the physique by two hormones: insulin and glucagon. Any additional glucose within the blood will get saved as glycogen within the liver.

In kind 2 diabetes, cells within the physique don’t reply nicely to insulin; as well as, the pancreas stops making sufficient insulin to assist regulate blood sugar.
Excessive blood sugar known as hyperglycemia. If left untreated, this situation can result in critical problems. These embody:
