| 英文摘要 |
Diabetes mellitus is classed as a metabolism disorder. Metabolism refers to the physical and chemical processes involved in the activities of the body. A person with diabetes has a condition in which the quantity of glucose in the blood is too elevated, or called hyperglycemia. This is because the body either does not produce enough insulin, which is one of hormones the body uses to maintain blood glucose levels, produces no insulin, or has cells that do not respond properly to the insulin the pancreas produces. Such mechanism causes too much glucose building up in the blood. As a result, the blood has plenty of glucose; the cells are not getting it for their fundamental energy and growth requirements. |
