Osteoporosis comes from the Greek, meaning “porous bones”. It is a disease in the bone the leads to an increased risk of fracture. Bones become brittle and break easily, even after very little trauma, for example falling at home. This is different from the traumatic fractures that occur after road accidents. The bones that most commonly break are around the wrist, the spine and the hip.
When suffering from osteoporosis the bone mineral density is reduced, the bone micro-architecture deteriorates, and the amount and variety of proteins in the bone is altered. There might not be any symptoms in the early stages of this condition until a fracture occurs. People with osteoporosis may suffer from spinal compression fractures resulting in a loss of height with a stooped back, also known as dowager’s hump.
Osteoporosis is defined by the World Health Organisation as a bone mineral density that is 2.5 standard deviations or more below the mean peak bone mass of average of young, healthy adults. Established osteoporosis includes the presence of a fragility fracture. To decide weather a bone mineral density test is needed or not, you can call us at 6471 2674 for an appointment!
While you can be affected by this bone-weakening disease in any bone in your body, fractures in the hip and spine are particularly serious, due to the fact that these often result in hospitalization or sometimes even death. Over the last 30 years in Singapore, cases of hip fractures have increased five times in women aged 50 and above, and 1.5 times in men of the same age group. Studies have shown that one in every five people with osteoporosis hip fracture died within a year. Those at risk of bisphosphosphonates, strontium ranelate or denosumab. The medications can reduce the chance of getting a fracture by about 50 per cent. All medications can have side effects but patients should take medication if the benefits outweigh the risks. Those who have low bone mineral density, low body weight, on steroids or with a family history of osteoporosis may need medication after consulting doctor.
The disease is split into three categories, classified as primary type one, primary type two, or secondary. The form of osteoporosis most common is women after menopause is referred to as primary type one or postmenopausal osteoporosis. Primary type two osteoporosis may arise at any age and affect men and women equally. This form of osteoporosis results from chronic predisposing medical problem or disease, or prolonged use of certain medications.
Prevention of osteoporosis is important. An adequate intake of calcium is recommended, to build strong bones. You lose calcium on a daily basis via bodily excretions such as urine, faeces and sweat. We also lose it when shedding skin, hair and nails. It is possible to replenish your loss by eating calcium-rich foods. Calcium rich foods include certain dried herbs, cheese, sesame seeds, tofu, almonds and green leafy vegetables. Calcium is better absorbed when taken in small amount throughout the day, so try to spread your calcium absorption. Exposure to the sun helps in the production of vitamin D. If you cannot eat enough naturally you can take supplements.
Apart from diet, other lifestyle changes include doing weight-bearing exercise to strengthen your bones. Tai chi, brisk walking, skipping, dancing, hiking, jogging and aerobics can help to build up your bones and strengthen them. Resistance exercises like weight-lifting, push-ups, and standing and rising on your toes can also help to increase muscles and decrease the risk of falls.
