PATHOLOGY

Detailed explanation-1: -In one category, type 1 diabetes, the cause is an absolute deficiency of insulin secretion. Individuals at increased risk of developing this type of diabetes can often be identified by serological evidence of an autoimmune pathologic process occurring in the pancreatic islets and by genetic markers.

Detailed explanation-2: -Type 2 diabetes occurs when the body doesn’t produce enough insulin to function properly, or the body’s cells don’t react to insulin. This means glucose stays in the blood and isn’t used as fuel for energy. Type 2 diabetes is often associated with obesity and tends to be diagnosed in older people.

Detailed explanation-3: -Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. This buildup of glucose in the blood is called hyperglycemia. The body is unable to use the glucose for energy. This leads to the symptoms of type 1 diabetes.
