Why is it important for me to get more vitamin D if I have COPD?

ANSWER

If you don't get enough vitamin D -- what doctors call “vitamin D deficiency” -- researchers believe it can make you more likely to get lung and airway infections that can cause flares. That can make your symptoms get worse suddenly.

If you avoid these flares, your lungs may stay healthier. Flares make it harder for your lungs to work. Over time, they can make your COPD worse. Serious ones can put you in the hospital. Some can be life-threatening.

Vitamin D also helps keep your bones and muscles healthy. In fact, it can keep you from having bone loss, especially if you're older. It can also prevent and treat osteoporosis.

So if you get enough vitamin D, it may be easier for you to build strength and be active. Both of those things can help you live better with COPD.
