Osteoporosis or Osteopenia
Have you had a bone density test? Did the analysis determine that your bone integrity is diminishing? This could lead to broken bones if not corrected. The test itself is reported in a statistical bell curve. Your practitioner either saw that you are on the good side of the bell curve compared to the population your age or your on the bad side of the statistical bell curve. If it was determined that you have an osteoporotic situation, you should take action.
Often, the leaching of bones occurs at older ages. Why? There is not much exercise or weight bearing activities anymore. BONES HARDEN BASED ON THE STRESSES AND STRAINS PUT UPON THEM. In retirement, we don't do much anymore. Men usually don't have bone density issues because they weigh more than women. Heavy women will generally not have bone density issues unless they are sitting around all the time. Weight and gravity will assist in bone density if you have some weight or gravity to put the strains on muscles. Don't use this as an excuse for fatness.
I recall years ago, watching television as they carried Russian cosmonauts from their space modules. They placed them on stretchers and carted them off. I assumed the cosmonauts were just tired. It was a safety precaution to keep them from breaking a bone once again being in a gravity environment after being weightless so long. It has been said that one trip to outer space will cause ten years worth of bone loss. When in outer space, there is no gravity and bones leach or turn to rubber. Today, there are exercises that the various cosmonauts and astronauts do in a space module when weightless. These exercises place necessary stresses and strains on muscles which in turn place strains on bones to keep them healthy and strong.
If you are a lighter weight person, you will probably experience bone loss. You don't have the gravity pull with the lesser weight. There are two types of exercise, Aerobic and Anaerobic. Aerobic exercise is the long enduring, huff and puff type of activity. Even brisk walking. Anaerobic exercise is shorter duration but requires your muscles to contract and work. I'm not opposed to either and indeed, both should be done throughout life. However, anaerobic or resistance work is the exercise best for bone density. If you don't know the proper ways of completing anaerobic exercise, a quick visit with a trainer or your local gym, you can find out what to do. Anaerobic exercise doesn't even require expensive equipment. Some things can be done at home with a little creativity. Using Bungee type cords to flex muscles in various ways will do wonders. If you have access to some simple weights when done properly will harden bones.
I'm very much opposed to the prescriptions for bone hardening. Often, these types of bone hardening prescriptions will hard bones so much, the bone will crystallize. Even some dentists will have you sign a waiver if you are using bone hardening prescriptions because they can potentially inadvertently break a jaw bone when working on your teeth. Bone fractures can still occur with these prescriptions because of the crystallization.
Taking Calcium supplements is somewhat of a problem as well. Some people take so much calcium, that it clogs up arteries, valves in the hearts, etc. Calcium carbonate is the most popular and the cheapest and the least absorbed. Calcium citrate on the other hand is a highly absorbable calcium but still needs to be done conservatively. Don't get me wrong, calcium is an essential mineral in which the body needs for several functions besides bone integrity. Often, health store personnel could assist in determining a good calcium supplement for you but don't over do it. Seek calcium rich foods. There are lists on the internet.
Remember, weight bearing exercises are far more effective for bone density than all the calcium supplements you could take in a day.
