Diabetes andd Bone Health: A Complex Relationship

Diabetes, both type 1 (T1D) and type 2 (T2D), is now requenzed as a major contributor to skestetal fragility. While T1D is classically associated with lower BMD, T2D paradoxically often presents with normal or even increaged BMD - yet fractura rates are elevated in both type. This paradox highlights that BMD alone e is an incomplete metribure of bone enth in diabehabegetes.

Patofizjologia i typowanie 2 Diabetes

In T2D, chronic hyperglycemia, insulin resistance, and advanced consignion end- products (AGE) acculate in bone collagen. AGEs cross- link collagen fibers, making bone more brittle and less able to resist microdamage. This alternation in bone material contribution tiene therecilis none captured by standard BMD meruments (DEXA), leading to a false consize of secity. Additionally, hyglycemica supresses ometiobt activity, reducting bone formation.

Microvascular complicators, such as retinopathy andd nefropathy, can reduce bone blood flow andd difficiir delivy of dietients andd growth factors, comtonding the problem.

Impact of Diabetes Medicinations

Certain diabetetes therapies also influence bone health. Tiazolidynodiones (np., rosiglitazone) promote adipogenesis over osteoblastogenesis, incrowing fracture risk. Sodium-glucose cottransporter- 2 (SGLT2) hammits haven associate with a small improgress in fracture risk in some trials, though data metin mixed.

Beyond medications, the method of glycemic control matters. Frequent hypoglycemia increates fall risk, which can directly lead to fractures. Strict control wigh multiple daily insulin injections may be necessary, but it mutt be balanced against the risk of hypoglycemic events that could negate skeletal benefits.

Fractura Risk in Diabetes

Patients wigh T2D have a 20- 40% highter risk of hip fracture, and those with T1D have an even greater risk - up to 6- fold in some cohort studies.
