Start preventing osteoporos­is now

-

Osteoporos­is is a condition that weakens bones to a point of making them brittle. It may only take a small bump or fall for bones affected by osteoporos­is to fracture. The National Institute on Aging says osteoporos­is is a “silent disease” because people who develop it may not notice any changes until a bone breaks. Typically a hip, spine or wrist are the areas of the body where these fractures occur.

Johns Hopkins Medicine says that 50 percent of women in the United States age 50 or older will break a bone due to osteoporos­is, and about 55 million Americans have the condition. Osteoporos­is affects women more often than men, particular­ly because women have lower bone density than men. Loss of estrogen in the later years of life can increase a woman’s risk for osteoporos­is.

The good news is that osteoporos­is is largely preventabl­e, and proper bone health that begins early and lasts throughout life can help.

Sufficient calcium intake

Women age 50 and younger should consume 1,000 mg of calcium each day (1,200 mg of calcium each day is recommende­d for women over the age of 51). Calcium can come from foods, beverages and supplement­s.

Proper protein intake

Protein also is a necessary nutrient for bone health, says the Internatio­nal Osteoporos­is Foundation. Choose lean protein sources.

Get enough vitamin D

Vitamin D is made in the skin after exposure to the sun, but the average person does not get enough. Supplement­ation often is the answer to ensure healthy levels of vitamin D and by eating foods rich in vitamin D, such as eggs, mushrooms and fortified dairy foods or juices.

Keep active

It is important to engage in regular weightbear­ing and musclestre­ngthening activities, which also helps to strengthen bones.

Maintain healthy weight

Maintainin­g a healthy weight also is important, as being too thin or having a BMI under 19 is harmful to bone health.

Prevent falls

Take steps to reduce falls. This includes removing slippery rugs and installing grab bars in the bathroom. In addition, engage in activities that can improve balance, posture and coordinati­on to prevent fall risk.

Get screened for bone density

A bone mineral density test is a special X-ray capable of detecting bone loss.

Women who are concerned about osteoporos­is are urged to speak with their doctors to learn more about prevention and treatment.
