Diabetic can cause foot pain, ulcers, gangrene and other diseases of the feet due to peripheral neuropathy, insufficient blood supply to the lower extremities and bacterial infection. Severe cases can lead to amputation, collectively known as diabetic foot.

Diabetic patients are 2 to 3 times more likely to have coronary heart disease than non-diabetic patients. Common ones include heart enlargement, heart failure, arrhythmia, angina pectoris, and myocardial infarction.

also known as diabetic glomerulosclerosis, is a common and intractable microvascular complication of diabetes, and one of the main causes of death in diabetes.

The duration of diabetes is more than 10 years, and most patients have retinopathy of varying degrees. Common lesions are iritis, glaucoma, cataract and so on.

Diabetic ketoacidosis occurs most often when insulin-dependent diabetes is untreated, when treatment is interrupted, or when stress is present. Diabetic patients are severely deficient in insulin, and the decomposition of fat is accelerated to generate a large amount of fatty acids.

The incidence of this complication is not high, but the fatality rate is high. Most of them occur in patients with hypoxic diseases such as liver and kidney insufficiency, or chronic cardiopulmonary insufficiency, especially those taking phenformin at the same time.

In the state of hyperglycemia, nerve cells and nerve fibers are prone to lesions. The clinical manifestations are spontaneous pain, numbness, and hypoesthesia in the extremities. Individual patients develop local muscle weakness and muscle atrophy. Autonomic dysfunction is manifested as diarrhea, constipation, urinary retention, impotence and so on.

The high blood sugar state of diabetic patients is conducive to the growth and reproduction of bacteria in the body. At the same time, the high blood sugar state also inhibits the ability of white blood cells to phagocytose bacteria, which reduces the patient's ability to resist infection. Common urinary tract infections, respiratory infections, skin infections and so on.

Most diabetic patients have impotence, premature ejaculation, low libido, menstrual disorders and other sexual dysfunctions, which can occur at the same time as diabetes symptoms, but most of them appear after diabetes symptoms. Medicine believes that the influence of diabetes on sexual function may be related to vascular disease and pelvic autonomic neuropathy.
