Q. I am 61 years old. My doctor recently tested me for vitamin D and found I am deficient. I was really surprised, since I play golf both summer and winter. (We go to Arizona in the winter.)
What are the causes and consequences of a vitamin D deficiency? My legs have become quite weak, so I golf with a cart. I even use a cart at the supermarket to make it all the way around the store. I would be grateful for any information you can send me.
A. Regular sunscreen use might block vitamin D production even though you spend time in the sun. Some medications can lower vitamin D levels in the body. They include prednisone (and other corticosteroids), some anti-seizure medications (phenytoin, primidone, valproic acid) and certain cholesterol-lowering drugs. We are sending you our Guide to Vitamin D Deficiency for more in-depth information.
Low levels of vitamin D are linked to bone pain, muscle weakness, cognitive impairment, depression, arthritis, and falls. You may need a supplement to get you back on track.
