What is
Bone Loss?
Bone loss occurs when there is
decreased calcification or reduced density of the bones. The
result is weak bones that are at increased risk of fracture.
Bone loss can occur as part of the normal aging process or
as a complication of cancer or cancer treatment.
Symptoms of
Bone Loss?
Bone loss is sometimes called a
silent disease, because it occurs without symptoms. People
may not know they have bone loss or low-density bones until
they become so weak that a sudden strain, bump, or fall
causes a fracture.
Fractures can occur in any bone. However, fractures to the
hip or spine are particularly troublesome and are often a
sign of bone loss. When these bones are healthy, they can
withstand significant impact; but when an individual
has low bone density, even a minor fall may result in a
fracture.
Causes Of Bone Loss
Being thin is associated with more bone loss. Body fat
increases certain types of estrogen, thin women tend to
have lower levels of estrogen. As a result, age and
estrogen-related declines in bone mass will have a greater
effect on them.
Some diets can cause bone loss. Losing a lot of weight,
putting it back on, and losing it again can lead to poor
nutrition and shifts in hormone levels. These ups and downs
can cause significant bone loss.
Certain diseases may lead to
hormonal imbalance that causes bone loss. These diseases
include hyperthyroidism, diabetes mellitus, Cushing's
disease, anorexia nervosa, and chronic kidney failure.
Some medications cause bone loss, including corticosteroids,
thyroid drugs, and anti-seizure drugs; some diuretics; and
chronic use of barbiturates. Some hormonal therapies for
breast cancer are also associated with bone loss.
Not getting enough calcium, vitamin D, or magnesium can lead
to bone loss. Hormonal changes, especially a drop in
estrogen levels, increase bone loss. |
