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.
