Diabetes is a great harm to the human body, and the occurrence of this kind of harm usually develops unknowingly. Therefore, patients with diabetes should be more aware of the dangers of diabetes, actively prevent and treat them, and go to a professional hospital in time to avoid delays in their condition.
1. Damage to the kidneys
Hyperglycemia, hypertension, hyperlipidemia, and abnormally elevated glomerular microcirculation filtration pressure promote the occurrence and development of diabetic nephropathy. The early manifestations are proteinuria and edema, and later renal failure may occur. Renal failure is the main cause of death in diabetes.
2. Harm the cardiovascular and cerebrovascular
The accompanying symptoms of cardiovascular and cerebrovascular diseases are fatal accompanying symptoms of diabetes. Mainly in the aorta, coronary arteries, cerebral atherosclerosis, extensive small vessel endothelial hyperplasia and capillary basement membrane thickening of microvascular diabetic disease. The uncoordinated contraction and expansion of blood vessels, the adhesion of platelets and the deposition of lipids in the walls of blood vessels lead to an increase in the prevalence of cardiovascular and cerebrovascular diseases and increased mortality in diabetic patients.
3. Harm to the eyes
Diabetes hyperglycemia can damage retinal blood vessels, causing vascular atresia and hypoxia in retinal tissue. Diabetic retinopathy and diabetic cataract are the main manifestations of diabetes hazard to the eyeball. Diabetes patients with mild symptoms will have reduced vision, and severe ones can cause blindness.
Fourth, diabetic foot
Due to the increase in blood sugar, diabetic patients will cause peripheral vascular disease, mainly lower extremity atherosclerosis, resulting in reduced sensitivity of local tissues to injury, insufficient blood perfusion, and local tissue damage due to external factors or local tissue infection Sometimes local tissue ulcers are more likely to occur. It often occurs in the feet, so it is called diabetic foot.
Common symptoms of diabetes
1. Sudden loss of vision
The lens of diabetic patients can cause blurred vision due to damage to the optic nerve, fundus vascular disease, dilated retinal veins, and bleeding. It also expands due to the penetration of water, and myopia occurs.
2. Postprandial hypoglycemia
In the early stage of diabetes, the process of insulin secretion is slow, and the postprandial blood sugar peak will pass, and hypoglycemia will occur, and symptoms such as dizziness, vertigo, and palpitation will appear after the meal.
3. Gradually lose weight
Severe hyperglycemia will have a typical “three more and one less” symptoms, that is, eating more, drinking more, and urinating more, but people will lose weight.
4. Slow wound healing
High blood sugar will affect the speed of wound healing. When the skin is damaged and the wound has not healed for a long time, blood sugar should be checked in time.
