5、 6Diabetes mellitus, or simply diabetes, is a group of metabolic diseases in which a person has high blood sugar, either because the pancreas does not produce enough insulin, or because cells do not respond to the insulin that is produced. This high blood sugar produces the classical symptoms of pol

6、yuria (frequent urination), polydipsia (increased thirst), and polyphagia (increased hunger). 01 Brief Introduction 702 Classification 2.1 Type 1 diabetes The pancreas undergoes an autoimmune attack by the body itself,and is rendered incapable of making insulin.Abnormal antibodies have been found in

7、 the majority of patients with type1 diabetes.Antibodies are proteins in the blood that are part of the bodys immune system,the patient with type1 diabetes must rely on insulin medication for survival. 02 Classification 2.2 Type 2 diabetes It previously referred to as non-insulin dependent diabetes

8、mellitus,or adult onset diabetes mellitus.patients can still produce insulin,but do so relatively inadequately for their bodys needs,particularly in the face of insulin resistance as discussed above.In many cases this actually means the pancreas produces larger than normal quantities of insulin.A ma

9、jor feature of type2 diabetes is a lack of sensitivity to insulin by the cells of the body.8 02 Classification 2.3 Other type of diabetes gestational diabetes,occurs when pregnant women without a previous diagnosis of diabetes develop a high blood glucose level. It may precede development of type 2

10、DM.Other forms of diabetes mellitus include congenital diabetes, which is due to genetic defects of insulin secretion, cystic fibrosis-related diabetes, steroid diabetes induced by high doses of glucocorticoids, and several forms of monogenic diabetes.9 2022-7-13 meta-变化的变化的 metabolism n.新陈代谢 metabo

13、s. At the other end of the spectrum , a very high birth weight (over 8.8 pounds or 4 kg) also is associated with an increased risk. Additionally, mothers of infants who had a higher birth weight (over 9 pounds) are at increased risk for developing diabetes.13 03 The major factors 3.2 Fat The distrib

14、ution of fat is important. The classic pear shape person (smaller waist than hips) has a lower risk of developing diabetes than the apple shape person (larger around the waist). The exact reason for this difference is unknown, but it is thought to have something to do with the metabolic activity of

15、the fat tissue in different areas of the body.14 03 The major factors 3.3 Irregular menses (menstruation) There is an association between the lengthening of the menstrual cycle and the risk for developing diabetes, particularly in obese women.those who had a cycle length of greater than 40 days were

16、 twice as likely to develop diabetes than those who cycled every 26 to 31 days. The association is thought to be linked with polycystic ovarian syndrome(PCOS) which is also known to be associated with insulin resistance. Insulin resistance may be a precursor for type 2 diabetes.15 03 The major facto

17、rs 3.4 inflammation In recent years we have begun to understand the importance of inflammation and heart disease. We now know that inflammation may play an important role in the development of diabetes as well. An inflammation marker known as C-reactive protein has been shown to be increased in wome

18、n at risk for developing the metabolic syndrome, and in both men and women at risk for developing type 2 diabetes.16 03 The major factors 3.5 Obesity and a sedentary lifestyle Obesity and a sedentary lifestyle are the biggest risk factors that are controllable.This is in part due to the fact that ob

19、esity increases the bodys resistance to insulin. Studies have shown that reversal of obesity through weight reduction improves insulin sensitivity and regulation of blood sugar.17 03 The major factors 3.6 smoking Smoking is harmful in many ways including increasing the risk of cancer and heart disea
