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. One of these sugar is the primary supply of vitality, or gasoline, for the physique. It’s additionally the first supply of vitality for the mind.
If 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 vitality.

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

In kind 2 diabetes, cells within the physique don’t reply properly to insulin; as well as, the pancreas stops making sufficient insulin to assist regulate blood sugar.
Excessive blood sugar is named hyperglycemia. If left untreated, this situation can result in critical issues. These embody:
Different issues attributable to excessive blood sugar embody foot issues, gum illness, pores and skin points, and listening to loss.
