Osteoporosis is a condition that occurs when the bones decrease in mass and strength. It is associated with low bone mineral density (BMD), caused by a reduction in the mineral content of the bones.
Throughout life, new bone is continuously added to the skeleton and old bone is taken away. Normally, this process is tightly regulated so that a healthy bone mass is maintained. In Osteoporosis, the rate of bone breakdown is greater than the rate of bone formation.
Maximum bone mass is reached by the mid 20s and after the mid 30s, bones begin to lose their mineral content. One of the most important bone minerals is calcium. As you get older, more minerals are taken from the bones than are put into the bones, meaning that the bones become weaker. Age-related Osteoporosis is the most common cause of decreased bone density. After the mid 30's , the outer shell of the bones becomes weaker and holes develop in the inner material.
Oestrogen deficiency, which affects many post-menopausal women, is a major cause of accelerated bone loss. Age-related testosterone deficiency in men is also associated with the development of Osteoporosis. The effects of both oestrogen and testosterone deficiencies are worsened by low calcium levels in the body.
When the bones are fragile, there is an increased risk of fracture, particularly of the hip, spine and wrist. Many cases of Osteoporosis are not detected until there is a bone fracture. In some cases of Osteoporosis, there may be no symptoms at all. In other cases, there may be pain in bones or muscles, especially in the back region.
Osteoporosis can be either primary or secondary. Primary Osteoporosis is the most common type and occurs as a result of age-related loss of skeletal bone. Seconday osteoporosis may result from surgical removal of a young woman's ovaries or certain medications such as loop diuretics, anti-convulsants and glucocorticosteroids.
There is no cure for Osteoporsosis, however, it can be prevented. Methods for preventing Osteoporosis include;
Age is not the only risk factor associated with Osteoporosis. Other risk factors include gender (women are more likely to develop Osteoporosis than men are), high alcohol intake, smoking, poor diet, little or no exercise, stroke, hyperthyroidism and some medications. Ask your Pharmacist if you are concerned about the effects of medication that you are currently taking.
Other risk factors for Osteoporosis include; inadequate calcium and vitamin D intake, lack of exercise, prolonged bed rest, excessive intake of salt and caffeine. Thyroid, kidney and bowel disorders along with some medications such as loop diuretics, anti-convulsants and glucocorticosteroids can aslo increase a person's risk of developing Osteoporosis.
Always consult your Doctor for the diagnosis and treatment of Osteoporosis. The diagnosis of Osteoporosis is usually made using a non-invasive test called a Bone Density Test. This technique uses x-ray beams to determine bone mineral density.
The treatment for Osteoporosis varies according to its cause. In most cases, lifestyle changes such as dietary modification, exercise and the avoidance of certain substances such as excess alcohol are required. Your Doctor may also recommend dietary supplements such as calcium and vitamin D, which help maintain bone strength if dietary intake is inadequate.
Various medications are available to restore oestrogen or progesterone levels or mimic the effects of these hormones to prevent the breakdown of bone. Other classes of drugs, such as the bisphosphonates and calcitriol, reduce the activity of the cells that are responsible for the breakdown of bone tissue.
Several dietary factors affect the passage of calcium in and out of the bones. There is a constant turnover of calcium and up to the mid 30's, deposition of calcium tends to outweigh the loss of calcium.
The diet should be rich in:
The diet should be low in:
Studies show that dietary soy supplementation may increase bone mineral content in post menopausal women, and protect against bone loss. Improving digestion with a little apple cider vinegar or lemon juice in water before meals may help to increase the excretion of digestive juices and the absorption of nutrients.
