What are the complications of diabetes in the elderly? Diabetes is a relatively common disease in our lives, with the majority of the elderly being affected. It can be very harmful to patients, and if left untreated diabetes can lead to complications that can affect patients even more. So what are the complications of diabetes in the elderly? Cataract According to statistics, about 30% of cataract patients are diabetics. Due to the high concentration of glucose in the blood and intraocular atrial water of diabetic patients, glucose is transformed into sorbitol substances in metabolism and accumulates in the crystal, causing swelling of crystal fibers, which then breaks and disintegrates and eventually completely blurs, causing patients to lose vision and even go blind. 2, difficult to control tuberculosis According to relevant statistics, diabetic patients with complications of tuberculosis accounted for 10% to 15% of patients with tuberculosis, 3-5 times higher than normal people. This is due to the poor resistance of diabetic patients, high sugar environment is more conducive to the growth and reproduction of tuberculosis bacteria. 3, nephropathy diabetic nephropathy is diabetes caused by microangiopathy in the kidney, is a common comorbidity of diabetes, usually occurs after 5 to 15 years of diabetes. 4, cardiovascular disease According to the survey, nearly half of the diabetic patients complications of coronary heart disease. The possibility of myocardial infarction in diabetic patients is 5 to 7 times that of normal people. Diabetes mellitus is mainly with sugar metabolism disorders, accompanied by protein and fat metabolism disorders, and even water, salt metabolism and acid and alkali imbalance. 5, cerebral thrombosis Investigation shows that the incidence of cerebral thrombosis in diabetic patients for non-diabetic patients 12 times. Diabetes due to increased blood sugar. Can make the blood become sticky, platelet aggregation increased. Blood flow is slow and cerebral thrombosis is easy to occur. At the same time, various metabolic disorders occur in the body, causing hyperlipidemia and hypertension, which aggravate atherosclerosis, and several factors act synergistically with each other, and eventually cerebral thrombosis occurs.
