Osteoporosis
WHAT
The language of medicine can be complicated and at times confusing. This section lays out in plain and simple English the basics of these conditions. As far as possible, technical terms and medical language is minimised or explained. What is the basic starting point for each of the conditions. What is the literal translation of the diagnostic label? What does this mean and what are the key symptoms of the disease?
Osteoporosis literally translated to a disease process, “porosis”, of the bones, “osteo”. It is characterized as low mineral density of bone resulting from either deficient calcium or protein content impairing structural integrity with an increased risk of fracture even following normal activity leading to falls, sudden trauma (even low energy trauma such as slipping on a curb) or lifting heavy objects. Diagnosing osteoporosis can occurs incidentally such as following an X-ray showing thinning of the bone or following an incident such as a fracture.
While not everyone experiences symptoms with osteoporosis, unusual backaches may indicate spinal fractures within the vertebrae, although many cases remain asymptomatic. The best way to diagnose osteoporosis if to screen individuals who are at risk pre-emptively so that this thinning can be detected at an early stage and treatment commenced before events such as fractures occur.
The risk factors include sex, medications and the presence of underlying medical conditions that impact the bodies ability to remodel the skeleton effectively. Treatment with exercise, dietary modification and drugs can then be recommended to individuals at risk.
WHO
The next section is who, the scientific word for this is the epidemiology of the condition. Epidemiology refers to the study of patterns and trends associated with diseases or injuries within a population. In other words, how common is the condition, what age range is affected? Are men and women affected equally? Does the frequency of the illness depend on what part of the world I live in? In other words, who is more likely to suffer from this condition.
Osteoporosis is a condition where bones become weaker and more prone to fractures. It often occurs in older people, especially women after menopause, but can affect anyone. In the UK, around 3 million people have osteoporosis, and it is estimated that 1 in 2 women and 1 in 5 men over the age of 50 will break a bone due to osteoporosis. The prevalence of osteoporosis is higher in women due to hormonal changes during menopause, which can cause bone loss. However, men can also develop osteoporosis, especially as they age, especially where there is a decrease in the amount of the male hormone testosterone.
Globally, the prevalence of osteoporosis is expected to increase as the population ages. It is estimated that by 2050, there will be 319 million people aged over 65 years with osteoporosis worldwide. There are several risk factors for osteoporosis, including age, sex, genetics, lifestyle factors, certain medical conditions, and medications. It is important to have regular bone density scans and speak to a healthcare professional if you have any concerns about osteoporosis.
WHY
Why has this condition affected me, and what is happening in my body that is causing it? We can break this down into two parts: aetiology (which is the study of what might be causing the condition) and pathophysiology (which is about what is happening in the body as the disease progresses). Scientists are still studying these areas, and we don’t have all the answers yet. This section will provide a simple summary of what we do know, without all the complex medical terms.
Osteoporosis is a bone disease that occurs when the body loses too much bone, makes too little bone, or both. As a result, bones become weak and may break easily from a fall, or in serious cases, from simple actions like sneezing or bending over.
The bones in the body are constantly being broken down and rebuilt, a process called bone remodeling. In healthy bones, the breakdown of old bone is balanced by the formation of new bone. Osteoblasts are specialised cells which increase the amount of mineralised bone in the skeleton while osteoclasts remove bone. A balance is maintained that constantly remodels bone over our lifetimes. However, with osteoporosis, bone breakdown outpaces the growth of new bone, leading to a decrease in bone density and overall bone strength.
Several factors can contribute to the development of osteoporosis, including age, sex, genetics, and lifestyle factors such as poor diet, lack of physical activity, and smoking. Medications also impact bone health such as steroids and medications for epilepsy. Medical conditions such as inflammatory arthritis also weaken the bones. In younger patients, eating disorders like anorexia can also lead to the development of osteoporosis. Women are at a higher risk than men due to the loss of oestrogen after menopause, which contributes to bone loss.
Osteoporosis is often referred to as a “silent disease” because it can progress for many years without any symptoms until a bone fracture occurs. Therefore, it is important to prevent osteoporosis by maintaining a healthy lifestyle and getting screened for osteoporosis if you are at risk.
HOW
The how section answers more practical questions. This discusses what the next steps are in getting towards a diagnosis. If you have been suffering from the symptoms of a rheumatic condition, you will ultimately need to be reviewed by an appropriate specialist and will likely require some form of further investigation to help confirm or refute a particular diagnosis. This section lays out the typical medical work up you can expect for any given condition.
A clinician can make a diagnosis of osteoporosis based on a combination of a patient’s medical history, physical examination, and diagnostic tests. As mentioned above, this diagnosis is sometimes made as a reaction to an event (such as a fracture) or incidentally because the bones appear unusually thin on an X-ray taken for an incidental reason.
During a physical exam, the clinician may check for signs of a curvature of the spine, loss of height, and tenderness over the bones. They will also ask about any falls, fractures, or family history of osteoporosis.
The most commonly used diagnostic test for osteoporosis is a dual-energy X-ray absorptiometry (DXA) scan. This is a painless, non-invasive test that measures bone density at the hip and spine. A DXA scan result is reported as a T-score, which compares a patient’s bone density to that of a healthy young adult of the same sex.
A clinician may also order blood tests to rule out other medical conditions that can affect bone health, such as hyperthyroidism or vitamin D deficiency.
Based on the results of the medical history, physical exam, and diagnostic tests, a clinician can make a diagnosis of osteoporosis and develop a treatment plan to reduce the risk of fractures and improve bone health.
WHAT NOW
Having now gained some better understanding of the condition; you now hopefully have a number of crucial questions on the background of the disease answered. The “What now” section outlines the road ahead. This includes an overview of the most common interventions that are likely to be considered for this including common medications and non-drug therapies. The list is not exhaustive and not all options listed are appropriate for every patient. What now also seeks to provide you a list of valuable additional resources where you can learn even more and get local and online support for your condition.
The goal of treatment is to prevent fractures, relieve pain, and improve the patient’s quality of life.
Disease education is an essential part of managing osteoporosis. Patients need to understand the risk factors, lifestyle modifications, and treatment options for osteoporosis. They should be advised to quit smoking, limit alcohol intake, exercise regularly, and consume a diet rich in calcium and vitamin D.
Medications are also an important aspect of treating osteoporosis. The first line of treatment includes bisphosphonates, which help to slow bone loss and reduce the risk of fractures. Other medications that may be prescribed include denosumab, teriparatide, and romosozumab. Second-line treatments may include calcitonin, hormone therapy, and selective oestrogen receptor modulators.
Specialist referrals may be necessary in some cases, especially for patients with severe osteoporosis or complex medical conditions. An endocrinologist or rheumatologist may be consulted for further management and treatment or in some centres, the care may be managed by a consultant with expertise in care of the elderly.
Therapies such as physiotherapy and occupational therapy may
also be recommended to improve mobility, balance, and strength, which can help
to reduce the risk of falls and fractures.
In summary, the management and treatment of osteoporosis
include disease education, medication, specialist referrals, and therapies to
prevent fractures, relieve pain, and improve the patient’s quality of life.
