Diabetes has become the third most serious chronic non-communicable disease threatening human health after oncology and cardiovascular disease, and is an increasingly serious public health problem. Currently, there are about 150 million people with diabetes worldwide, and it is expected to increase to 300 million by 2025. As of 2003, China has become the second largest country with diabetes. The increased medical costs associated with treating diabetes have become a heavy burden on health care in all countries. The complications of diabetes are divided into: 1) macrovascular complications, including cardiovascular and cerebrovascular diseases, lower limb vascular diseases, which can lead to myocardial infarction, cerebral infarction and diabetic foot in serious cases, with high death and disability rates, and seriously affect the quality of life of diabetic patients. (2) Microangiopathy, diabetic nephropathy can be manifested as increased urinary microprotein in the early stage and uremia in the late stage; diabetic retinopathy can lead to blindness. 3) Diabetic neuropathy: sensory nerve disorder, motor nerve disorder, vegetative nerve disorder, visceral dysfunction, neurogenic bladder and urinary retention, neurological joint damage. 4) Infections, such as tuberculosis, pneumonia, urinary tract infections, skin infections, etc. The key to reducing or delaying diabetes complications is to keep blood glucose in the ideal range. This requires the concerted efforts of diabetic patients and their diabetic physicians. I hope this helps you!
