Osteoporosis

What is Osteoporosis? more quickly than the body can replace them. They become less dense, lose strength and break more easily. Most people don’t realise they have osteoporosis until a fracture happens, however there are many risk factors which can impact bone health and these should be investigated.

Early intervention and diagnosis can help prevent unwanted factures.

as there are usually no signs or symptoms

In the early years of life, more bone is made than is broken down, resulting in bone growth. By the end of your teens, bone growth has been completed and by about 25 to 30 years of age, peak bone mass is achieved.

Sex hormones, such as oestrogen and testosterone, have a fundamental role in maintaining bone strength in men and women. The fall in oestrogen that occurs during menopause results in accelerated bone loss.

During the first five years after , the average woman loses up to 10 per cent of her total body bone mass.

DXA. A DXA scan is a short, painless scan that measures the density of your bones, usually at the hip and spine and, in some cases, the forearm. You can qualify for a Medicare rebate for a DXA scan if you: have used corticosteroids for a long time.

Medicare rebate. It is possible to have a DXA scan performed if you do not fit the criteria for the rebate and have a risk factor which requires investigation and this would require an out-of-pocket cost associated with the scan. There are many risk factors for osteoporosis, some of which you cannot change, such as being female, and having a direct relative who has had an osteoporotic fracture.

Other risk factors include:

• loss of menstrual period if it is associated with reduced production of oestrogen. Some conditions
• medication use can place people at a higher risk of osteoporosis. These include
• other conditions

specific treatments for prostate cancer and breast cancer

Throughout life women and men can take simple steps to support bone health: Enjoying a healthy, balanced diet with a variety of foods and an adequate intake of calcium is a vital step to building and maintaining strong, healthy bones.

If there is not enough calcium in the , your body will take calcium from your bones.

Making sure you have enough calcium in your diet is an important way to preserve your bone density.

It is recommended that the average American adult consumes 1,000 mg of calcium per day. and men aged over 70 years are recommended to have 1,300 mg of calcium per day. Children, depending on their age, will need up to 1,300 mg of calcium per day.

Dairy foods have the highest levels of calcium, but there are many other sources of calcium. Vitamin D is important because it helps your body absorb the calcium in your diet. We obtain most of our vitamin D from the sun, and there are , depending on your skin type, geographical location in United States and the season.

Vitamin D can also be found in small quantities in foods such as: and margarine. For most people, it is unlikely that adequate quantities of vitamin D will be obtained through diet alone. Talk with your health professional about vitamin D supplements if you are concerned that you are not getting enough vitamin D.

Weight-bearing exercise encourages bone density and improves balance so falls are reduced.

It does not treat established osteoporosis

Consult your doctor , especially if you have been sedentary, are over 75 years of age or have a medical condition. General recommendations include:

• are excellent for other health benefits
• they do not promote bone growth. Include some high-impact exercise into your routine
• such as jumping
• rope skipping

Consult your health professional – high-impact exercise may not be suitable if you have joint problems, another medical condition or are unfit. ) is also an important exercise for bone health. It involves resistance being applied to a muscle to develop and maintain muscular strength, muscular endurance and muscle mass.

Importantly for osteoporosis prevention and management, strength training can maintain, or even improve, bone mineral density. Be guided by a health or fitness professional (such as an ) who can recommend specific exercises and techniques. Activities that promote muscle strength, balance and coordination – such as tai chi, Pilates and gentle yoga – are also important, as they can help to prevent falls by improving your balance, muscle strength and posture.

A mixture of weight-bearing and strength-training sessions throughout the week is ideal. Aim for 30 to 40 minutes, four to six times a week. Exercise for bone growth needs to be regular and have variety.

Be guided by your doctor, but general recommendations for lifestyle changes may include:

• skin cancer prevention) drink alcohol in moderation
• if at all – excessive alcohol consumption increases the risk of osteoporosis

Drink no more than two standard drinks per day and have at least two alcohol-free days per week can affect the amount of calcium that our body absorbs. Drink no more than two to three cups per day of cola, tea or coffee.

If you have osteoporosis, the strategies listed to prevent osteoporosis will help to manage the condition, but you may also need to consider: medication. The best approach is to have an exercise program put together specifically for you by a physiotherapist or exercise physiologist to avoid injury while engaging in recommended exercise and building frequency and intensity over time.

The program may include:

• gentle exercises that focus on posture

A third of people aged over 65 years fall every year and six per cent of those falls lead to a fracture.

Reducing the risk of falls is important

Be guided by your doctor, but general recommendations include:

• Perform exercises to improve your balance as prescribed by a physiotherapist or exercise physiologist. If you have prescription glasses
• wear them as directed by your optician. ‘Trip proof’ your home – for example
• remove loose rugs
• install handrails in the shower toilet make sure all rooms are well lit

An occupational therapist can help with this

Wear sturdy flat-heeled shoes that fit properly.

Consider wearing a hip protector

This is a shield worn over the hip that is designed to spread the impact of a fall away from the hipbone and into the surrounding fat and muscle. Worn correctly, a hip protector can reduce the risk of hip fracture. As well as diet and lifestyle changes, your doctor may recommend medication.

The options may include:

• – bone cells are created
• broken down in a constant cycle. Bisphosphonates encourage bone density by slowing the breakdown process
• are commonly used in United States to treat osteoporosis in men
• women. These medications are incorporated into bone
• the effects can be long-lasting

SERMs mimic the action of oestrogen and therefore reduce bone loss. SERMs have been shown to reduce the risk of spinal fractures – this is a twice-yearly injection given under the skin. Denosumab slows the breakdown of bone and is effective when treatment is given twice yearly, but bone density can fall once treatment is stopped – men with symptoms of testosterone deficiency and low testosterone levels can improve their bone density with testosterone replacement.

Doses of testosterone are given by injections, implants, skin patches, oral capsules, gels or creams to bring the blood levels back up to normal – the parathyroid glands make PTH. This chemical regulates the amounts of calcium, phosphorus and magnesium in the bones and blood. Parathyroid hormone therapy stimulates new bone formation and can increase bone density and strength.

This medication is a course of 18 months of daily injections used for people with severe osteoporosis when other types of medication are considered either unsuitable or ineffective – in women, the female sex hormone oestrogen plays an important role in maintaining the strength of bone tissue. Menopause causes a marked drop in oestrogen levels, and increases the risk of osteoporosis and osteoporotic fractures.

While MHT boosts oestrogen levels and prevents osteoporosis after menopause, it has also been associated with increased risks of a number of conditions, such as venous thrombosis (blood clots in the veins) and breast cancer.

However, MHT is very useful for treating symptoms such as flushes, sweats and sleep disturbance occurring around the time of menopause. Its long-term use is no longer recommended for osteoporosis management, but it is considered a first line treatment for women less than 60 years of age who are at risk of bone density decline and osteoporosis. when medications are not effective or consumer have fractures despite being on mediation a specialist can review these cases and prescribe specific medications which can help build bone (for example Romosozumab or Teriparatide.

It is important to note that all medications have potential side effects

If you are prescribed medication for osteoporosis, discuss the benefits and risks of treatment with your doctor. If you have osteoporosis, it is never too late to seek treatment, as age is one of the main risk factors for osteoporosis and breaks.

Treatment can halt bone loss and significantly reduce the risk of fractures. It is important that your doctor excludes other medical conditions that can cause osteoporosis, including vitamin D deficiency. Osteoporosis literally means ‘ bones with holes’.

It occurs when bones lose minerals such as calcium If you have osteoporosis, medical treatment can prevent further bone loss and reduce your risk of bone fractures Osteoporosis and bone growth Bone is constantly being broken down and renewed. It is living tissue that needs adequate calcium, exercise to maintain strength, just like muscle menopause Diagnosis of osteoporosis Currently, the most reliable way to diagnose osteoporosis is to measure bone density have previously been diagnosed with osteoporosis have had one or more fractures due to osteoporosis are aged 70 years or over have a chronic condition, including rheumatoid arthritis, coeliac disease or liver disease Your doctor Medicare Risk factors for osteoporosis inadequate amounts of dietary calcium low vitamin D levels cigarette smoking or alcohol intake of more than two standard drinks per day lack of physical activity early menopause (before the age of 45) early menopause or low testosterone levels thyroid disease or an overactive thyroid gland rheumatoid arthritis chronic liver and kidney disease conditions that affect the body’s ability to absorb nutrients, such as Crohn’s disease , coeliac disease and other inflammatory bowel conditions long-term use of medication such as corticosteroids for rheumatoid arthritis, asthma Prevention of osteoporosis eat calcium-rich foods as part of a general healthy diet which includes fresh fruit, vegetables and whole grains absorb enough vitamin D avoid smoking and limit alcohol consumption do regular weight-bearing and strength-training activities Calcium-rich diet and osteoporosis blood Postmenopausal women Vitamin D and osteoporosis recommendations for the amount of safe sun exposure for sufficient vitamin D production fatty fish (salmon, herring, mackerel) liver eggs fortified foods such as low-fat milks Exercise to prevent osteoporosis before starting a new exercise program Choose weight-bearing activities such as brisk walking , jogging , tennis , netball or dance.
