At present, the number of people with diabetes in China has reached 109 million, ranking first in the world, which means that one in ten adults is a diabetic. However, diabetes is scary, and the complications of diabetes are even scarier. There are even many diabetic patients who died from diabetes complications. So Heng Xuan, a famous Hong Kong actress who starred in “The New Zha Shifu” and “The Legend of the Shooting Hero”, is believed to be a memory of many people’s youth, but she was in and out of the hospital many times because of her diabetic foot, and had to have her toes removed to save her life due to foot ulceration, and had four surgeries in just two months, and eventually died without resisting the disease. There is also Shi Jieqiang, who was famous with Stephen Chow’s movie “The Inquisitor” and can be seen in many Hong Kong movies behind him. He was loved by the audience because of his comical looks, but because he always loved sweets, plus his body was obese and got diabetes, he died on February 22, 2018 at the age of 60 due to complications from long-term unsatisfactory blood sugar control. There are also statistics that the incidence of cardiovascular disease in diabetic patients is two to four times higher than in the general population, and ischemic heart disease is the leading cause of death in diabetes, accounting for 60% to 80% of deaths in diabetic patients. However, the incidence of eye blindness is up to 25 times higher in diabetics than in non-diabetics. And diabetes also triggers nephropathy, which starts with proteinuria, reduced kidney function and finally uremia. Diabetic nephropathy accounts for 10%-30% of the total mortality from diabetes, and as the age of onset is getting younger, the proportion of deaths from diabetic nephropathy is getting higher. Then and how to avoid these terrible complications? Control blood sugar: good or bad blood sugar control is the key to determine the occurrence of diabetic complications. We need to avoid high-sugar and high-calorie foods by eating less and more meals, chew slowly during meals, exercise properly one hour after meals, and take glucose-lowering medications regularly and quantitatively. Regular blood pressure and lipid checks: controlling blood pressure and lipids can reduce the risk of macrovascular disease and death in diabetic patients. Blood pressure should preferably be controlled at 130/80 mmHg, total cholesterol <4.5 mmol/L and triglycerides <1.7 mmol/L. Regular vision checks: regular eye examinations for early detection and treatment; blood sugar control and stable dilated eye examinations once every six months; eyes with a history of If you have a history of internal eye surgery (cataract surgery, glaucoma surgery, etc.), you should shorten the time of eye examinations or follow the doctor's instructions for re-examination. Weight control: Many type 2 diabetes are caused by obesity because the fat in the body is resistant to insulin, resulting in a relative lack of insulin secretion, so it is imperative to reduce weight in order to avoid complications and treat diabetes. Pay attention to foot care: check your feet carefully every day to see if they are broken, observe the temperature and color of the skin of your feet; wash your feet with warm water every day and dry them in time; choose soft, breathable cloth shoes or moccasins; avoid walking barefoot to avoid injury and infection, and massage your feet more in summer to unblock the blood vessels. Regular electrocardiogram, cardiac ultrasound, cardiac enzymes and other tests, pay attention to the screening of macrovascular complications. For patients suffering from diabetes and obesity can try to choose weight loss surgery, which can not only reduce weight but also reduce insulin resistance caused by fat accumulation of simple obesity, thus playing a role in reducing blood sugar. It can also reduce the risk of diabetic complications, reduce the chance of cardiovascular disease by 1/3, and greatly reduce the risk of cardiovascular mortality and cardiovascular events.
