Dr. Mehmet Oz
Dr. Oz welcomes his college roommate, Dr. Scott Forman, to talk about orthopedics. From osteoporosis to foot care, Dr. Forman has the answers!

Who should be concerned about osteoporosis?
Osteoporosis is a big problem, Dr. Forman says, especially for post-menopausal, Caucasian women of European descent. He recommends calcium supplements in the form of calcium citrate plus 400 or 800 IU of vitamin D a day to help with absorption.

How important is weight lifting for bone health?
Although many people think of bone's structure as static, the skeleton is in fact very dynamic and constantly being absorbed and rebuilt, Dr. Forman says. Because bone will heal at lines of stress, and muscles are attached to bone, by working your muscles with weight, it will pull on the bone and stimulate it to become denser.

What's best for my feet? Who can benefit from an orthotic?
Dr. Forman says orthotics (arch support or foot pads are some examples) are generally over-prescribed and expensive. He notes that every foot is unique, and what's more important is buying shoes that are comfortable and fit your foot well. Don't buy the first pair of shoes you try on. Instead, give yourself plenty of time and try on at least 5 pairs of shoes until you find the perfect fit.

Does it pay to buy pricey athletic shoes?
Yes and no, Dr. Forman says. You need some minimal level of materials, but the most important thing is to compare your choices and buy whichever shoe fits your foot the best.

Are high heels bad for your feet?
Not necessarily, Dr. Forman says. Some women's feet adapt to shoes better than others. Stick to this rule of thumb no matter what type of shoe you purchase: the minimal shoe width should be no less than 1/2 inch smaller than your x-rayed foot.

Do shoes cause bunions?
Shoes don't cause bunions—they are genetic and whether or not you will get them depends on your parents, Dr. Forman says. Shoes can cause pain or aggravate a bunion. If a bunion is painful, either modify the shoes you are wearing or consult a physician to discuss surgical options.
