Hip and wrist fractures are a common result of osteoporosis. A new drug, Evenity, reduces the risk of vertebral fractures, but it doesn’t significantly reduce the risk of non-vertebral fractures. Other drugs do. Atypical fractures of the femur can occur with bisphosphonate drugs, but the benefits exceed the risk. Evenity… read more "Evenity for Osteoporosis"
Juvent is a small vibrating platform that is advertised to provide all kinds of health benefits for everyone by just standing on it for 10 minutes a day. They have no convincing evidence and the price is exorbitant. Ads for Juvent keep popping up in my Facebook feed. It is… read more "Juvent"
Osteoporosis is routinely treated with bisphosphonates to prevent fractures. A new study suggests that osteopenia should be treated too. But questions remain. Bisphosphonate drugs have been shown to increase bone density and prevent fractures in postmenopausal women with osteoporosis (remember Sally Field in those ads for Boniva?) but what about… read more "Osteopenia: When Does Decreased Bone Density Become a Disease Requiring Treatment?"
Hormone replacement therapy in menopause is safer and more effective than we have been led to believe. A new book examines the evidence and sets the record straight. Estrogen replacement stops hot flashes cold and is a veritable Fountain of Youth. Estrogen replacement is dangerous: it kills women. It prevents… read more "Estrogen Matters"

Newtonian physics was taken as “the truth” until we learned in the 20th century that it didn’t apply on cosmological or subatomic scales. Medicine and human… read more "K2: The Vitamin, Not the Mountain"

It identifies a serious problem, debunks medical misconceptions and contains words of wisdom. We are healthier, but we are increasingly being told we are sick. We… read more "Overdiagnosis"
A recent story on NPR accused the drug manufacturer Merck of inventing a disease, osteopenia, in order to sell its drug Fosamax. It showed how the definition of what constitutes a disease evolves, and the role that drug companies can play in that evolution. Osteoporosis is a reduction in bone… read more "Osteoporosis Drugs: Good Medicine or Big Pharma Scam?"
There is a new industry offering preventive health screening services direct to the public. A few years ago it was common to see ads for whole body CT scan screening at free-standing CT centers. That fad sort of faded away after numerous organizations pointed out that there was considerable radiation… read more "Ultrasound Screening: Misleading the Public"
