Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that makes it harder for you to breathe and can cause secondary headaches.
If you have COPD, finding the cause of your headache is important because of the potential for life-threatening complications.
Headaches from COPD happen from a lack of oxygen to your brain combined with too much carbon dioxide. COPD headaches commonly occur in the morning after waking up due to a buildup of carbon dioxide in your blood while you sleep. Visit your doctor immediately in case you are suffering from morning headaches for proper evaluation.
