As all sugar lovers know, diabetes is still incurable. It lurks in the body and is not harmful in itself, but complications are like its claws and teeth, bent on getting bigger and stronger to tear at our healthy organism. All we need to do is to combine the efforts to hold down the claws and teeth of diabetes and stifle the complications, and we will be able to maintain our health. In general, complications of diabetes are divided into acute and chronic. Acute complications appear quickly with the appearance of ketone bodies in the blood and urine, a decrease in blood pH and an increase in blood osmolarity. The main manifestations are fatigue, loss of appetite, nausea and vomiting, polyuria, dry mouth, deep and fast breathing, headache, drowsiness and even coma, which may directly endanger your life. Acute complications of diabetes are likely to occur after infection, improper diet, trauma, surgery, etc. If the above clinical phenomena occur, you should visit the hospital promptly for clear diagnosis and treatment. Regular glucose-lowering treatment and blood glucose monitoring can basically eliminate the emergence of acute complications of diabetes. Of course, the most prevalent risk to the majority of sugar lovers is the chronic complications of diabetes, such as diabetic nephropathy, diabetic eye disease, diabetic foot disease, diabetic neuropathy, diabetic skin lesions, diabetic periodontal disease, etc.. It can lead to uremia requiring dialysis to maintain life, loss of vision or even blindness, foot ulceration or even amputation resulting in disability, numbness and tingling in hands and feet, diarrhea and constipation, sexual dysfunction, abnormal sweating, incomplete urination, itchy skin, loose teeth or even loss of teeth, etc. Diabetes is more likely to cause atherosclerosis than non-diabetic people, mainly invading coronary arteries, cerebral arteries, aorta, renal arteries and peripheral arteries of limbs, causing coronary heart disease, stroke, accelerated brain aging, increased pulse pressure difference of blood pressure, bruised and cold feet, etc. Especially when it attacks both the heart microvasculature and nerves, it easily leads to painless myocardial infarction, heart failure, arrhythmia, cardiogenic shock and sudden death. Due to the rapid increase in income levels and drastic lifestyle changes, the number of people suffering from diabetes is very high, and the chronic complications of diabetes are diverse and have no symptoms in the early stages, which can quietly erode the health of patients. In general, type 1 diabetes should be screened for chronic complications at least once a year after 3-5 years of disease. Because type 2 diabetes starts insidiously and often may have been present for many years by the time it is discovered, screening for chronic complications is required as soon as it is diagnosed. Our work has found that the incidence and severity of complications in patients in the Lingang area are much higher than in the supermarkets. These chronic complications are better if detected early and treated early, with many disappearing completely, and are poor and incredibly costly when they progress to advanced stages. Early detection of diabetes and good glycemic control can significantly reduce the occurrence of these chronic complications. It is also important to note that diabetic patients are prone to infections, such as urinary tract infections, lung infections, skin infections, tuberculosis, shingles, etc. Serious infections such as sepsis, liver abscesses, and lung abscesses, which are already relatively rare, can also often be seen in diabetic patients. In general, as long as the comprehensive control of diabetes indicators to meet the standards, and regular check-ups, to consolidate their own defense, so that diabetes is paralyzed, not able to flare, then diabetes is not terrible. Diabetics can fully achieve this through the diabetes prevention and control network of community and secondary and tertiary hospitals led by the Sixth Hospital.
