Osteoporosis Is An Age Related Disease Of The Skeletal System

Introduction: Osteoporosis is an age-related disease of the skeletal system characterized by both low bone mass and bone structural degeneration (Nunes, 2011). Understanding osteoporosis is important because it is continues to be overlooked and undertreated, causing high numbers of bone fractures each year –in the elderly, these bone fractures can be debilitating or even life threatening (Eastell, 2009). Osteoporosis manifests when an imbalance between bone resorption and bone rebuilding occurs – this is due to changes in osteoclast and osteoblast activity. I chose this topic because osteoporosis affects millions of people, and research will allow me to better understand this common yet complex, and very perilous bone disease. Types: There are two types of osteoporosis, primary and secondary. Primary osteoporosis is more common and has no direct cause. It is usually more prevalent in women who are postmenopausal where the rate of bone loss increases while the rate of bone regeneration decreases. Secondary osteoporosis, unlike primary, has a direct cause, such as an illness like leukemia, cushings syndrome, or type 1 diabetes. These diseases cause an increase in bone resorption, and weakening of the bones. Pathophysiology: Bones are made up of two layers, the trabecular and cortical layers. The trabecular layer is internal and spongy-like, where the cortical layer is external and more compact. These layers are continuously broken down and reformed by two cells known asShow MoreRelatedElderly Populations Case Study968 Words   |  4 PagesOne in six Canadians have a chronic disease, with these chronic diseases being especially prevalent in the elderly population, individuals 55 years of age or older. Elderly populations have four times the rate of chronic disease compared to the overall population (Government of Canada, 2017). In fact, population aging was stated as one of the three most prominent elemental determinants of chronic disease development, along with globalization and urbanization, by the World Health Organization (WHO)Read MoreA Brief Note On The Highland Beach Group1218 Words   |  5 Pagesprone to diseases such as osteogentic sarcoma, osteomallacia, and lastly osteoporosis as a conseq uence. For this study I must look at the femurs of individuals in F.A.U.’s Highland Beach collection for any signs of osteoporosis and it’s possible causes. If there are any signs of osteoporosis it maybe was due to a low vitamin D diet and in consequence a low calcium intake.

Osteoporosis is defined as a â€Å"skeletal disorder characterized by compromised bone strength predisposing to increased risk of fractures (Manolagaas, 2014). Osteoporosis is defined as â€Å"a disease characterized by low bone mass and deterioration of bone tissue (What is osteoporosis?2014). Osteoporosis is sometimes also referred as â€Å"silent thief† as the bone loss occurs very slowly and silently without any symptoms (OsteoporosisRead MoreOsteoporosis Is The Most Common Chronic1725 Words   |  7 PagesOsteoporosis is translated from the Greek and literally means â€Å"porous bone â€Å" .It is the most common chronic, metabolic bone disease in the U.S.A, resulting in osteopenia an d fractures in spine , hip and wrist. In addition osteoporosis is progressive, and the skeletal fragility often leads to disabling fractures (hip fractures) and even death.

Therefore healthy bones contribute to the overall health of a living organism. However, bones are susceptible to infections and diseases much like the body parts of the rest of the body. These diseases/infections span anywhere from bone cancer and osteomyelitis to osteoporosis alongRead MoreEssay on Forecasting Denosumab957 Words   |  4 Pagesdevelopment of the drug. The products that Amgen produces are not growing well and their market share is declining. Also it has seen a decline in its stock value. So the profitability of the company is at stake. 2. The target disease is an increasing function of the population age and thus the market is available. But the manner in which the drug is positioned will make the difference in the success of Denosumab for Amgen. How compelling is the drug proposition? (For Denosumab) At an initial glance
