Diabetes Type 2

Diabetes Type 2 is the most common form of diabetes. Although it can occur at any age, it is more common in people who are overweight, sedentary, and over middle age.

Glucose is the main source of energy for body cells.

When blood sugar levels rise, as is normal after a meal, the pancreas gland located behind the stomach secretes the hormone insulin.

Insulin enters and circulates in the blood and acts on the insulin receptors present in muscle, fat cells and other tissues of the body.

Binding of insulin to these receptors causes the glucose transporters to come to the cell surface.

This facilitates the entry of glucose into these cells.

In Diabetes Type 2 the production of insulin is low and sometimes there may be resistance to Insulin.

The circulating insulin fails to facilitate the absorption of glucose into the cells and to keep the blood glucose level at optimum levels.

This results in the rise of blood glucose levels.

The excess in blood glucose reacts with proteins in tissues to form what are known as advanced glycation end products, or AGE's. AGE's create an inflammatory condition in the vasculature, which causes heart disease and damage to other organs such as the kidneys.

Diabetes can eventually cause damage to the heart, arteries, kidneys, nerves, eyes and skin.

葡萄糖是主要的能源来源,为人体细胞。

当血糖水平上升,因为是正常后,吃一顿饭,胰腺腺位于背后的胃分泌荷尔蒙胰岛素。

胰岛素进入流通,在血液和行为对胰岛素受体存在于肌肉,脂肪细胞和其他组织中的人体。

结合胰岛素,以这些受体导致葡萄糖转运来细胞表面。

这有利于在入职的葡萄糖进入这些细胞。

在2型糖尿病胰岛素的产生,是在低水平,有时候甚至有可能是胰岛素抵抗。

循环胰岛素失败,以方便吸收的葡萄糖进入细胞,并保持血糖水平在最佳水平。

这一结果在崛起的血糖水平。

过量血糖反应蛋白在组织中,以何种形式被称为晚期糖化终产物,或年龄的。时代的创造一种炎症状态,在血管,造成心脏病和损害其他器官,如肾脏。

糖尿病可最终会损害心脏,血管,肾脏,神经,眼睛和皮肤。
