Abstract:
It has been shown that diabetic patients have bone fragility independent of bone mineral density. Recently, diabetes-related bone disease is recognized as one of diabetic complications. It is reported that advanced glycation end products(AGEs)collagen cross-links, low bone turnover with osteoblastic dysfunction, and abnormality of microarchitectures such as cortical porosity and deterioration of trabecular bone structure are involved in diabetes-related bone disease. AGEs and homocysteine directly and negatively affect osteoblasts and osteocytes. Moreover, anti-diabetic drugs also affect bone metabolism. Therefore, the underlying mechanisms are very complex. In this review, we describe the effects of diabetes on bone metabolism based on the recent evidence.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
