People who suffer from asthma may be more prone to bone mineral density decrease.
Researchers analyzed the medical records of over 7,000 adult patients in Seoul, Korea and found links between bone loss and asthma. People with a certain symptom of asthma had much lower bone mineral density in one of their spine's region than those who do not have asthma characteristics. 216 people who had airway hyperresponsiveness (AHR) had lower bone density in their lumber spine.
Based on the research found in Annals of Allergy, Asthma and Immunology, American College of Allergy, Asthma and Immunology's (ACAAI) scientific journal, femur bone and lumber spine density was much lower in people with asthma or AHR than those who do not. Around 45 percent of the patients had a lower than average bone density or osteopenia and six percent was diagnosed with osteoporosis. 30 percent of people without AHR had osteopenia and only four percent had osteoporosis.
Reasons for the link between asthma and bone loss are yet to be singled out but it could be low vitamin D levels, corticosteroid use and even race. The study revealed findings that still need further investigation. Oral corticosteroids are related to adverse effects including osteoporosis but it is the most effective asthma treatment.
Because of it being associated with adverse effects, allergists always prescribe the lowest effective dosage of oral corticosteroid if required. Patients are also encouraged to inhale the medication if possible instead of taking it orally.
Steroids can decrease bone build up because it stops calcium absorption. The medication can interfere with sex hormone production that can cause weak muscles, increasing the risk of fall and other fractures. As per the National Institutes of Health (NIH), people with asthma may also avoid key ingredients for healthy bones such as milk, other dairy products rich in calcium and weight-bearing exercise.
"Asthma is a serious disease that can be life-threatening," associate editor of AAI journal Dr. John Oppenheimer said. "It is important that those with asthma and other breathing problems continue their prescribed treatment. It is also imperative that allergists discuss the potential of the disease itself or as a consequence of therapy in asthma sufferers."
