Resistance training benefits are unique and just as important as aerobic exercise benefits for living longer and better. So what is resistance training and how much do you need?
Osteopenia is a close relative of the bone-weakening disease, osteoporosis. It, too, is bone mineral density that is lower than normal, but it?s not low enough to qualify for a diagnosis of osteoporosis. If you have osteopenia, it?s important to strengthen your bones, because you are at greater risk for osteoporosis and bone fractures in the future.
Your risk for osteopenia increases as you age, because bones begin to break down faster as you get older. In women, the rate of bone loss speeds up dramatically after menopause because the body no longer produces the hormone estrogen, which helps build bones. Other risk factors include a family history of osteoporosis and a slim body frame. You may also be more prone to thinning bones if you?ve had an eating disorder like anorexia, you received radiation or chemotherapy to treat cancer, or you took steroid medicine to treat an autoimmune disorder such as rheumatoid arthritis.
Osteopenia doesn?t cause any symptoms. You might not realize you have weak bones until the condition progresses and you develop a fracture. Your doctor can diagnose osteopenia and osteoporosis with a bone density test, called a dual-energy x-ray absorptiometry (DXA) scan. This test compares the mineral content, or density, of your bones against those of a younger person of your gender. The result is reported as a T-score. A T-score of between -1.0 and -2.5 means you have osteopenia. A score of -2.5 or lower means you have osteoporosis.
If your bone density is low, your doctor will recommend that you start doing more weight-bearing exercises, such as walking or dancing. Nutritional interventions include getting more calcium and vitamin D, and limiting caffeine and alcohol. Bone-building medicines such as alendronate (Fosamax), risedronate (Actonel), or raloxifene (Evista) may also be an option.
In addition to its key role in imparting strength to bones and teeth, calcium plays a critical role as a messenger in cell-signaling pathways throughout the body and is necessary for normal cell function, transmission of nerve signals, secretion of hormones, blood coagulation, muscle contraction, and muscle relaxation.
According to the National Institutes of Health, osteoporosis is a disease that weakens bones and makes them more prone to breaks. To determine whether you have osteoporosis, your physician will order a bone mineral density test to take a “snapshot” of your bone health. The test can identify osteoporosis and
Vitamin D deficiency symptoms have been linked to numerous health problems, including heart disease, depression, and even cancer. In fact, a recent study conducted by Boston University researchers revealed vitamin D deficiency actually affects your DNA: “Any improvement in vitamin D status will significantly affect expression of genes that have
What does “osteoporosis -2.5” mean? To answer that question, we start with bone density scans, sometimes referred to as bone densitometry or dual-energy x-ray absorptiometry (DEXA, also written as DXA). Such scans have become an increasingly popular testing modality as more than 10 million adults in the United States alone
One in three women over age 50 suffers a fracture due to osteoporosis, a condition that causes fragile bones, according to a report issued by the International Osteoporosis Foundation in October 2013. Although osteoporosis itself causes no symptoms, it raises the risk of a bone fracture, which can be painful
Fibromyalgia symptoms may respond to vitamin D supplementation
People who suffer from the chronic pain and fatigue of fibromyalgia may benefit from taking vitamin D supplements, according to a study published in the February 2014 issue of the journal PAIN. Since there is no known cure for fibromyalgia, treatment focuses on
Q: I have pain in the bottom of my foot, in the area of my heel. What could this be?
A: It’s possible that you have plantar fasciitis, characterized by pain in the morning when you take your first step, followed by slight improvement, and then more pain later in the
Of all the classic osteoporosis symptoms of the spine, the possibility of “hunchback” should motivate you to a prevention strategy. No matter your age or bone density, there’s much you can do now…
What is osteoporosis? Think of it this way: Healthy bones are in a state of continuous breakdown and rebuilding. This process, called remodeling, is performed by specialized cells called osteoclasts, which resorb (break down) old bone, and osteoblasts, which form new bone.
In young adults, remodeling happens in a balanced fashion
