Diabetes can induce a variety of complications, including life-threatening diseases such as coronary heart disease, stroke and kidney failure, as well as highly disabling diseases such as diabetic foot and retinopathy. Now, diabetes has an additional charge of inducing fractures. Compared to coronary heart disease and stroke, fractures may not sound as dangerous. “It takes a hundred days to break a bone”, so it’s always better not to die, right? You are wrong, once the elderly because of osteoporosis fracture, not only then will cause a lot of damage, even if then not life-threatening, there is a great risk of disability; in a long time in bed, the elderly and will face infection, multi-organ functional decline and other problems, many of the elderly in the occurrence of fracture bedridden, will pass away in a short period of time, even if the recovery is often difficult to return to the previous state. Osteoporosis is not simply a lack of calcium, but is related to abnormal bone metabolism, and the causes of osteoporosis are linked to diabetes mellitus. Diabetes is closely related to osteoporosis and fractures. The incidence of fractures is increased in both type 1 and type 2 diabetic patients. There are many mechanisms why diabetes can cause osteoporosis or fractures. Diabetes is a metabolic disease of the endocrine system, and osteoporosis itself is closely related to several hormonal and bone metabolic conditions. For example, diabetic patients are more likely to have imbalance of calcium and phosphorus metabolism, while stimulating parathyroid hormone secretion, which enhances osteolysis and reduces bone mass; insufficient insulin secretion, which in turn affects bone formation and conversion, decreases bone density. In addition, if a diabetic patient has a long course of disease, various complications, such as eye and nervous system complications, can cause the patient to feel dull and increase the chance of falling and having a fracture, especially for patients who have developed osteoporosis. Therefore, prevention of osteoporosis and fractures needs to be taken seriously for diabetic patients. First of all, diabetes must be controlled to correct metabolic abnormalities and avoid unnecessary calcium and phosphorus metabolic disorders to prevent bone loss at the source. At the same time, diabetic patients need to be examined in terms of bone density, and early diagnosis and prevention will be more effective in preventing the occurrence of this complication.
