Question #1
I have been on a once a week pill for osteoporosis for the last year. Now my DR. wants me to do a yearly injection. Is this something you would advice for patients? Thank you, Beryl

When it comes to medication used to help avoid or minimize osteoporosis there are multiple ways to take it. It comes in daily, weekly, monthly, quarterly and yearly dosings. The yearly medication has been around for a few years and entails getting an IV infusion of the drug every 12 months. This method has reduced some of the immediate side effects of this type of medication including severe fatigue. But it has also been shown to increase the risk of developing heart rhythm problems called atrial fibrillation. In recent years other studies have also found it can also increase the risk of developing jaw bone problems. But for those who have a tough time complying with the more frequent dosages, or have more side effects from them, this could still be a good option. Talking with your doctor about the convenience of the once a year dose as well as the side effects of this medication can help you make an informed decision about whether this is the best medication to use.

Question #2
Dr. I see lots of people wearing black in the heat of the day. It was my understanding that black and dark colored clothing absorbed light and heat and was not healthy or practical to wear, especially in the summer. Am I wrong on this one? Steve

The overall answer to this question is a big "it depends". Although dark clothes do absorb more sunlight and add to the heat that way some experts feel that dark clothes also absorb more body heat so help reduce body temp as well. Light clothes do reflect sunlight more so might help reduce body heat from this source. But how much light gets absorbed or reflected depends heavily on how much sunlight you're exposed to. How cool you'll be in clothes not only depends on the color of the fabric but also how thick it is and how much wind you'll be exposed to. If you're going to be in direct sunlight then lighter colored clothes might be best to avoid heat. But otherwise it's more important to focus on the thickness of the fabric and not as much on the color.
