The main cause of fractures in older adults is osteoporosis.  As we age our bones become less dense.  This causes them to become weak. There are a few things you can do to help.   Get a bone density test if you are over 65.  It will tell you how strong your bones are. Calcium is important to keep bones healthy and strong.  You need about 1,000-1,200 mg a day.  Adults over 70 need 1,000-2,000 units of vitamin D per day.  The very best way to get enough vitamin D is by taking a supplement.  Exercise is another way to keep bones healthy and strong.  Speak with your Loveland Family Practice doctor about getting enough calcium.
