This article discusses diabetes, including its types, symptoms, risk factors, and treatments.
Definition and types
Diabetes is a chronic condition that occurs when your pancreas does not produce enough insulin or when your body cannot properly use the insulin that is produced.
Insulin is a hormone that helps manage your body’s blood sugar levels. When your body cannot produce insulin or use it properly, it affects how your body turns the food you eat into energy. Your body turns most of what you eat into sugar, called glucose, and releases it into your bloodstream.
When your blood sugar levels increase, it sends a signal to your pancreas to release insulin. This allows your body to use these sugars as energy.
When you have diabetes, this system does not work as it should. Your blood sugar increases to potentially unsafe levels and may lead to further health issues.
