Vitamin D deficiency common in patients with lung disease

A new study from Korea has uncovered a high prevalence of vitamin D deficiency in individuals with chronic obstructive pulmonary disease (COPD), as well as a significant relationship between vitamin D deficiency and airflow limitations. Exercise capacity also tended to be decreased in participants with vitamin D deficiency.

"About 80% of the 193 patients with COPD in the study had vitamin D deficiency compared with 40% to 60% of Koreans in the general population," said Dr. Sang-Do Lee, senior author of the Respirology study.
