1. Kidney diseases: including glomerulosclerosis, renal arteriosclerosis and pyelonephritis. The former is mainly characterized by intermittent proteinuria and edema, and hypertension and renal insufficiency occur in the late stage. Severe repeated infection can cause high fever, low back pain, hematuria and other symptoms of renal nipple necrosis.
Infection: The most common are skin purulent and fungal infection, followed by tuberculosis, urinary tract infection and lung infection.
Third, eye diseases: cataract, retinopathy. Early telangiectasia forms hemangioma, and later it presents proliferative lesions, which can cause blindness in severe cases.
Cardiovascular diseases: including myocardial diseases, hypertension, arteriosclerosis, coronary heart disease and cerebrovascular accidents. Vasculitis obliterans of lower limbs can cause intermittent claudication, pain and gangrene of lower limbs. Some patients may be complicated with painless myocardial infarction, arrhythmia, cardiogenic shock and sudden death.
5. Neuropathy: Peripheral neuropathy is more common, with sensory disturbance as the main symptom in the early stage and symmetrical pain in the lower leg or lower limb. When motor nerves are involved in the future, muscle tension tends to decrease. Tendon reflex is overactive in the early stage and decreases and disappears in the late stage. Complications of type 2 diabetes may occur after autonomic nerve involvement, such as abnormal sweating, postural hypotension, urinary retention, intractable diarrhea and abnormal pupil changes.
