Quick Read – Tips to Prevent Weak Bones
WHAT IS OSTEOPOROSIS AND OSTEOPENIA
Osteoporosis is a disease characterized by thinning of bones and increased fragility – what we call a loss of bone mass or reduction in bone mineral density (BMD). This usually starts and continues silently for many years, and the first manifestation of this condition is usually a fracture often after an injury, event or trauma which may otherwise be considered quite trivial or unimpactful. The usual sites of such fractures are the hip, spine, wrist, and shoulder.
Osteopenia refers to a lower bone mineral density (BMD) or bone mass, as compared to normal but not low enough to significantly increase fracture risk and be considered as osteoporosis. However, osteopenia can develop into osteoporosis sooner or later.
Over 200 million people worldwide and more than 50 million people in India suffer from osteoporosis or osteopenia.

WHAT CAUSES OSTEOPOROSIS AND WHO IS AT RISK
Unfortunately, no single cause or definite prevention has yet been identified, therefore the logical way to go will be to know who all are at higher risk than the general population, and screen them for their bone mineral density (BMD).
Increasing age and menopause in women are the most established risk factors. Others include family or past personal history of fractures, physical inactivity and associated medical conditions like diabetes, smoking, inflammatory disorders of the bowel (IBD), arthritis, asthma, hormonal disorders, and some cancers. Long-term intake of certain medicines can also increase the risk of bone loss like PPI-antacids, steroid medicines, hormones and anti-cancer drugs.
Screening for osteoporosis is most important in people having a combination of the risk factors below –
HOW TO GET SCREENED FOR OSTEOPOROSIS?
The only way to know that one has osteoporosis is either by routine screening, or after a fracture occurs. The thin and fragile bones in osteoporosis can lead to relatively minor injuries/trauma causing fractures. Most concerning are the fractures of the hip and spine. Therefore screening and timely intervention is advised especially when the mentioned risk factors are present.
DXA, sometimes known as DEXA (dual-energy X-ray absorptiometry) is the most standard, well-recognized, and reliable test for screening and diagnosis of osteoporosis, as well as monitoring improvement with treatment. DEXA is an X-ray-based test available in all standard labs. It gives the Bone Mineral Density (BMD) measurement result as a ‘T score’ (normal T score is ≥ -1.0, low bone mass or osteopenia is between -1.0 and -2.5, and osteoporosis is ≤ -2.5). In India, the DEXA test costs between 1500 -2500 INR, depending on how many body sites are being screened.
Ultrasound is another screening test used often in ‘BMD camps’ which are conducted as free osteoporosis screening camps at clinics or health centers. Here checking is done by a small, portable, easy to carry quantitative ultrasound (QUS) machine in which one places the foot. This is useful as a quick screening test as it is always done free of charge, but the T score standardized cut-offs of DEXA do not apply here and each of these ultrasound machines has its own calibrations and cut-off values. One cannot use these camp machines for checking improvement in BMD with treatment, and these machines can miss early disease as they use only the foot to check for bone thinning, where the reduction in bone mass may occur later than the hip or spine which DEXA checks. So, it is always best to confirm the diagnosis with DEXA and also use it for follow-up checks.
ONCE DIAGNOSED, WHAT IS THE TREATMENT
If you get diagnosed in time before a fracture becomes the reason for your diagnosis…you are fortunate!
Your Orthopedic doctor will start you on a calcium supplement with vitamin D and other vitamins/minerals (a guide to the different types of calcium/ vitamin D supplements available). Sometimes other drugs that are expensive but stronger and effective may be added if you have multiple risk factors, very low bone mass, are likely to or have already had a fracture. These may include injections (like zoledronate, teriparatide, denosumab) or/and a nasal spray (calcitonin). In some women, hormone therapy with estrogen supplements may be considered too.
Apart from medicines, you will be advised diet and lifestyle modification with regular walking or other appropriate exercises/sports, and care to be taken against trauma, accidents, or injuries.

The article is very useful and written in language the common man can understsnd. It enlightens regarding the limitations of the ‘instant BMD reading gadgets’ without dismissing them as useless, which orthopaedists normally do. Hence the article scores high on credibility. Annual injections and sprays do evoke scepticism and I am looking forward to the writer’s next article that will throw more light on these. Lots of appreciations to the writer for this service.
That’s really crazy that there is a thirty percent incidence in women after menopause. My aunt recently fractured a bone and so she thinks she might have this. We’ll have to look more into postmenopausal fracture treatments. http://tymloshcp.com/
yes…prevention of fractures with timely screening, diagnosis and calcium supplements is the best way to go
Someone necessarily lend a hand to make critically articles I’d state. This is the very first time I frequented your website page and up to now? I amazed with the analysis you made to create this actual post incredible. Great process!
It’s interesting when you mentioned that an ultrasound machine can be used as a screening device to check osteoporosis since it can help diagnose musculoskeletal conditions. It is very important for healthcare facilities to acquire this equipment that is small and portable so the process of screening will be fast and smooth. Therefore, I would like to think if a hospital wants to improve its equipment, it should get an ultrasound machine from a reliable supplier.
I’m extrеmely impreѕѕed with yoսr writing skiⅼls ɑs well as with the layout on yօur weblog. Keep up the nice quality writіng, it’s rare to see a nice blog like this one today.
Thanks for helping me understand that ultrasound screening can help catch any early diseases or issues with a patient. I guess I need to get my mom checked with this since she might be having issues with her bones now.
Thanks for pointing out that osteoporosis is a disease characterized by thinning of bones and increased fragility. My mother thinks she has osteoporosis so this is helpful. I guess we should look for a clinic on Monday that has bone density scanning to diagnose osteoporosis before a broken bone occurs.
For most recent news you have to visit web and on the web I found this website as an excellent site for latest updates.
Pretty! This was an incredibly wonderful post. Thank you for supplying this info.
