Patients with chronic liver disease are often combined with abnormal bone metabolism, also known as hepatic bone disease, with reduced bone mass and osteoporosis being the most common. The literature reports that the incidence of osteoporosis in combination with chronic liver disease is about 12%-55%, and the incidence of fracture is about 5%-20%. Once a vertebral fracture or femur fracture occurs, it will have a great impact on the quality of life of patients with chronic liver disease. Clinical experience tells us that all causes of cirrhosis are at risk of osteoporotic fractures. In order to detect abnormal bone metabolism early and intervene early for treatment, several guidelines recommend regular bone density testing (dual-energy X-ray bone densitometry) for patients with cirrhosis, which is a convenient, rapid and accurate non-invasive test to determine whether you have an estimation check or osteoporosis in hand.
