Are you concerned about your bone health? Do you worry about osteoporosis? According to the CDC, more than 10 million Americans have low bone density that makes them more vulnerable to fractures. For many older people, a fracture can be devastating, reducing mobility and possibly even leading to death. What does the latest medical science tell us about how you can maintain strong bones? At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

We have added extra information to these notes, but not to the interview itself. Strong Bones You may have seen Halloween skeletons or even chewed the meat off a bone that you then dropped on a plate with a clatter. No wonder we usually think of bones as hard, unchanging objects. Dead bones are. But living bones are quite different. Strong bones are constantly undergoing change. Scientists call it remodeling. One set of specialized cells, osteoclasts, breaks bone tissue down and recycles it. Another set, the osteoblasts, builds bone back. Ideally, their activities are in balance. But if the osteoclasts start to get ahead, as they tend to do while we age, that can weaken bone. The result is low bone mass, known as osteopenia, or even serious bone loss called osteoporosis. This puts a person at risk for fractures. Who Gets Osteoporosis? Osteoporosis may have been less common a hundred years ago or more, when many people had to do manual labor that put stress on their bones. That helps for strong bones, so today’s sedentary lifestyles can undermine bone health. Although we think of osteoporosis as typically affecting postmenopausal women, men can lose bone mass too. Medications may contribute to the risk for bone loss. Steroids such as prednisone or methylprednisolone are especially risky if taken for a long period of time. Androgen deprivation therapy for prostate cancer is a risk factor specifically for men. Wait–MEN Can Get Osteoporosis? Q. My husband and I have two friends with significant disability largely due to spinal fractures as a result of osteoporosis. One man was always an avid exerciser, including running marathons. Both men are over six feet tall and have always appeared to be muscular. My husband is shorter and is physically active, playing tennis and going to the gym regularly. Because of our friends’ bone issues, I advised him to request a DXA scan to assess his bone health. The nurse practitioner told him that it was not recommended for men. I am still concerned that he may be at risk for osteoporosis. Are there medical studies that determine the risk factors for men? A. The nurse practitioner was mistaken. Men can develop osteoporosis, as your friends discovered. Many medical guidelines recommend that men over 70 be tested with a DXA scan to assess bone health. If your husband has low testosterone levels or has taken medications such as prednisone, he could be at increased risk for a fracture. He would be prudent to have the assessment. Diagnosing Osteoporosis Doctors assess bone mineral density with imaging called dual-energy X-ray absorptiometry, or DEXA for short. Then they compare the results on the scan to the results they would expect from a 30-year-old person. Results more than 2.5 standard deviations from that could result in a diagnosis of osteoporosis. A person who experiences a fracture without trauma, such as falling from standing height, is also suspected and often diagnosed with osteoporosis. Non-Drug Approaches to Strong Bones: People who want to keep strong bones need to focus on exercise. High intensity exercise can be helpful, but brisk walking may be enough. Tai chi and yoga are also popular. If you have been diagnosed with osteoporosis, be sure to check in with your doctor before you start a new exercise program. Building balance and core strength without increasing your risk of a fall (and thus a fracture) would be ideal. Our guest expert, Dr. Kendall Moseley, says the jury is still out on technology such as vibrating platforms, weighted vests or vibrating belts. More studies should show how valuable these could be. Following a diet that supplies adequate protein, vitamin D and calcium is also crucial. If you must take a calcium supplement, calcium citrate may be well tolerated and absorbed. How Do Doctors Treat Osteoporosis? Physicians prescribe several different types of medications to help curb bone less and perhaps even build it back. Some of the oldest and least expensive are the bisphosphonates such as alendronate (Fosamax). These slow bone break down and give the osteoblasts a chance to catch up. They can be hard on the digestive tract, though, and they have been associated with a few rare but alarming side effects: jawbone deterioration and atypical thigh bone fracture. Most people seem to do well on them. Doctors generally prescribe them for up to five years. Did You Forget Evista? Another type of osteoporosis medicine is called raloxifene (Evista). It is appropriate only for women, because it is an estrogen modulator. It acts like estrogen in the bones and reduces bone loss. In the breast and uterus, it opposes estrogen activity. Raloxifene does double duty in reducing the risk of breast cancer as well as osteoporosis. Like all drugs, though, it has some worrisome side effects. It can increase the risk of blood clots that cause deep vein thromboses and strokes. What About Prolia? Denosumab (Prolia) is a monoclonal antibody that also interferes with osteoclasts. That is how it improves bone density. One thing to keep in mind about Prolia is that stopping it requires careful planning and backup medication. Otherwise, a patient can lose all the bone that was built rather quickly and may suffer debilitating fracture. This Week’s Guest Kendall F.

Welcome to this podcast of The People’s Pharmacy. Joe 00:06-00:13 You can find previous podcasts and more information on a range of health topics at peoplespharmacy.com. Joe 00:14-00:27 Hypertension is often called the silent killer, but osteoporosis might be considered a silent and deadly disorder. This is The People’s Pharmacy with Terry and Joe Graedon. Terry 00:34-00:41 If an older person breaks a hip, the consequences can be disastrous. They often lose mobility and they may even die. Joe 00:42-00:50 The focus for osteoporosis is usually on older women, but we should remember that men can also lose bone and become vulnerable. Terry 00:51-00:57 There are drugs that hurt bone health as well as help build it back. What about supplements or exercise? Joe 00:57-01:06 Coming up on The People’s Pharmacy, the science of strong bones, lifestyle, medication, and movement. Terry 01:14-02:32 In The People’s Pharmacy health headlines, semaglutide has gotten a lot of attention over the past few years. If you don’t recognize this generic drug name, you probably do recognize the brand names. Ozempic for type 2 diabetes and Wegovy for weight loss. Both these medications are self-administered injections, but not everyone is enthusiastic about needles. There’s also an oral form of semaglutide called Rybelsus. The FDA has approved it for treating type 2 diabetes six years ago, and so far it has mostly gone under the radar. A new study published in the New England Journal of Medicine demonstrated that oral semaglutide at 25 mg a day helped people without diabetes lose significantly more weight than placebo. The randomized trial included more than 300 volunteers and lasted approximately a year and a half. This could be good news for people who have trouble accessing injectable semaglutide or keeping it
