Primary Osteoporosis
There are two primary kinds of osteoporosis: type I osteoporosis and type II osteoporosis. The determining factor for the actual existence of osteoporosis, whether type I or type II, is the amount of calcium left in the skeleton and whether it places a person at risk for fracture. Someone who has exceptionally dense bones to begin with will probably never lose enough calcium to reach the point where osteoporosis occurs, whereas a person who has low bone density could easily develop osteoporosis despite losing only a relatively small amount of calcium.
Type I osteoporosis (postmenopausal osteoporosis) generally develops in women after menopause when the amount of estrogen in the body greatly decreases. This process leads to an increase in the resoprtion of bone (the bones loses substance). Type I osteoporosis occurs in 5% to 20% of women, most often between the ages of 50 and 75 because of the sudden postmenopausal decrease in estrogen levels, which results in a rapid depletion of calcium from the skeleton. It is associated with fractures that occur when the vertebrae compress together causing a collapse of the spine, and with fractures of the hip, wrist, or forearm caused by falls or minor accidents. Type 1 accounts for the significantly greater risk for osteoporosis in women than in men.
Type II osteoporosis (senile osteoporosis) typically happens after the age of 70 and affects women twice as frequently as men. Type II osteoporosis results when the process of resorption and formation of bone are no longer coordinated, and bone breakdown overcomes bone building. (This occurs with age in everyone to some degree.) Type II affects trabecular and cortical bone, often resulting in fractures of the femoral neck, vertebrae, proximal humerus, proximal tibia, and pelvis. It may result from age-related reduction in vitamin D synthesis or resistance to vitamin D activity (possibly mediated by decreased or unresponsive vitamin D receptors in some patients). In older women, types I and II often occur together.
Secondary Osteoporosis
Secondary osteoporosis is caused by other conditions, such as hormonal imbalances, certain diseases, or medications (such as corticosteroids). Details on the many other causes of secondary disease are included throughout this report. Secondary osteoporosis accounts for < 5% of osteoporosis cases. Causes include endocrine disease (eg, glucocorticoid excess, hyperparathyroidism, hyperthyroidism, hypogonadism, hyperprolactinemia, diabetes mellitus), drugs (eg, glucocorticosteroids, ethanol, dilantin, tobacco, barbiturates, heparin), and miscellaneous conditions (eg, immobilization, chronic renal failure, liver disease, malabsorption syndromes, chronic obstructive lung disease, RA, sarcoidosis, malignancy, prolonged weightlessness as found in space flight).
Thank you! This was a very interesting read. I never knew there were different types. Guess I need to do more research/reading, huh? Yeah, telling someone to exercise is easier said than done! My RD tells me to keep moving, no matter how little. Some days you just gotta be a lump though. LOL
We walked to the park today and by the time we came back, I thought my knees were gonna totally give out on me. Took some vidodin and a hot shower which seemed to help. I'd love to start bicycling once it gets warmer here. Have you (or anyone else) tried that yet? I wouldn't think it'd be considered high impact. I just wonder how bad my wrists/shoulders/knees would hurt after the fact. I have seen people riding around on this nifty bikes with three wheels that are low to the ground - it almost looks like they're sitting! I bet it'd be a great ab work out, too. Sorry, went off on a tangent and got a little chatty! I'm blaming the meds! [QUOTE=SnowOwl]My RD continually stresses that exercise is important, for bone, for strength and flexibility, and for people with RA she contends people who exercise regularly have fewer flares. Goodness knows I try, however possible, each day. There are chair exercises that don't require standing or walking/running, if I'm really hurting or whupped I do those. It can surely seem unfair that exercise is recommended when a person's condition is such as makes that so difficult, but movement can be as valuable as meds.[/QUOTE]
My RD stresses exercise too
You want a good laugh? There's these free exercise shows on OnDemand that show "flirty" moves you can do. I watched one and tried... and I failed. I was definitely NOT brining sexy back!!LOL- I have On Demand I never knew they were there. I'll have to see what I can do!
Lynn .. do you take Tai Chi Classes? is that what LinB said she was going to do too?
I have the desire.. but truly lack motivation.... I'm too tired *sigh*
Me too Babs....sooooo tired

justsaynoemore2009-06-21 06:09:57I've never run across a dr who seemed to have had a microphone in the office. I do have drs that have incredibly good memories and if they dictate notes immediatly followingthe appt they are likly to get them right.
my RD is putting my information right into a data file on his computer as we speak.. he's typing away.. stops.. asks a question.. and types my responses.... .
