Mr. Shi, a police officer of a police station in Xuhui District, Shanghai, told a meeting of diabetic patients about his changes after the minimally invasive diabetic surgery at Shanghai Sixth People’s Hospital, where he not only lost weight to normal, his blood sugar returned to normal, and even his original high blood pressure and high blood lipids were reduced to normal range. It turned out that the police uncle had been diabetic for 8 years before the surgery, oral hypoglycemic drugs have been unable to control high blood sugar, once also because of diabetic ketoacidosis and emergency hospitalization. Later changed to subcutaneous insulin injection, although barely control the blood sugar, but also brought great trouble. Because as a civilian police, is the protector of social security, to often go to the police to deal with all kinds of emergency situations, but also often night duty, high pressure, high risk, three meals irregular. In order to control blood sugar when on duty also carry insulin pen, and because of excessive weight, lower limb joints also appear degenerative arthritis. This makes the police uncle distressed, although the leadership, colleagues are taking care of him, but over time, caused him great mental stress. The policeman uncle had been following up with the Endocrinology Department of Shanghai Sixth People’s Hospital to regulate his blood sugar. During an outpatient follow-up visit, Deputy Chief Physician Yu Haoyoung of the Endocrinology Department introduced the new method of minimally invasive surgery to treat diabetes carried out by the General Surgery Department of the Sixth Hospital and recommended him to undergo surgery. After a detailed preoperative examination and evaluation, in December 2011, the director of the Department of General Surgery, Zhang Pin, performed a laparoscopic gastric bypass for him, and his postoperative recovery was smooth. The glycosylated hemoglobin is lower than 6.5%, the arthritis in the lower extremities has healed, and the hypertension and hyperlipidemia have dropped to the normal range. Now on duty, he is obviously much more relaxed, agile, active thinking, in handling a variety of cases with ease, often praised by the leadership and colleagues, no wonder he said he was like a cocoon into a butterfly like a new life.
