Degenerative disc disease is not genetic. Inheritance of Degenerative Disc Disease refers to whether the condition is inherited from your parents or runs in families. The level of inheritance of a condition depends on how important genetics are to the disease.
Bone fractures, particularly in the spine or hip, are the most serious complication of osteoporosis. Hip fractures often are caused by a fall and can result in disability and even an increased risk of death within the first year after the injury. In some cases, spinal fractures can occur even if you haven't fallen.
In other words, your bones lose density, become weak, and are prone to fractures. This process isn't the sole cause of osteoporosis; there are other factors that contribute to and exacerbate the onset of the disease. Your diet has a significant impact on the health of your bones.
