Bones and joints Archive

A 2022 study found that people with sleep apnea are more likely to have low bone density. Apnea may trigger low oxygen levels and inflammation that impair the body's continuous bone renewal process.

Staying active when knee osteoarthritis flares helps the joint stay flexible. But activity should be modified to take pressure off the knee. That could mean walking instead of running, or playing pickleball instead of tennis. Other activities that are easy on the joint include riding a stationary bike, using an elliptical machine, practicing yoga, swimming, walking pain-free distances on flat terrain, doing upper body strength training, or core strengthening. Warming up before activity helps to loosen stiff knee joints.

A 2022 study found that vitamin D deficiency significantly increases the likelihood of age-related loss of muscle strength, known as dynapenia, a major risk factor for falls.

After a drug is approved by the FDA, unexpected safety problems may be discovered. Depending on the level of concern, different safety warnings may be issued –– including a black box warning designed to call attention to serious or life-threatening side effects.

People with knee arthritis who don't feel ready for joint replacement can take a number of steps as they ponder the possibility. These include getting knee injections or wearing a brace to reduce pain, modifying activities (such as exercise) that aggravate knee pain, losing weight to take pressure off the knee joint, exercising more to help with weight control, seeking physical therapy, getting underlying health conditions under control, doing research about knee replacement, and talking to an orthopedic surgeon.

Pain in the shoulder, elbow, or wrist without obvious injury is common. Possible causes include arthritis, bursitis, frozen shoulder, rotator cuff tear, tendinitis, or nerve compression in the carpal tunnel or the cubital tunnel. Home remedies include rest, ice, compression, or elevation; over-the-counter anti-inflammatory pain relievers; and devices such as a splint or brace. Other treatments include physical therapy or steroid injections. Surgery is usually a last resort.

Most men will lose about 30% of their muscle mass over their lifetimes, a natural process called sarcopenia. But no matter a man's age, he can still build and maintain muscle with strength training. Strength training consists of upper- and lower-body exercises using free weights, weight machines, resistance bands, or body weight. Hiring a personal trainer who can design an individual program and teach proper exercise techniques and form is an ideal first step for beginners and those returning to exercise.

Aerobic and muscle-building exercises can trigger physiological changes that improve blood vessels and metabolism in ways that help prevent all the major risk factors that contribute to heart disease. These include high blood pressure, diabetes, obesity, and unhealthy cholesterol levels. Exercise can also improve mental health problems such as depression and stress, which are common but underrecognized risks for heart disease.

Gout strikes when too much uric acid builds up in the body and triggers severe pain, swelling, and redness in one or more joints, often in the big toe. New research suggests that an episode may increase the risk for a heart attack or stroke over the following two months.

Every second, someone age 65 or older suffers a fall, making it the No. 1 cause of injury-related death among this age group. The best way for older adults to protect themselves is to address the three main physical conditions that contribute to falls: weak stabilizer muscles, poor core strength, and balance issues. They can do this by improving their side-to-side motion through specific exercises and playing racquet sports, doing abdominal exercises, and practicing tai chi.
