Anyone can develop this condition, as a result of damage to your lungs that gradually limits their ability to take in oxygen.
Here are 2 signs which indicate that your lungs could be in trouble
Many of us who experience breathlessness think that it's a problem related to age or being out of shape and not do anything about it until it becomes extremely serious. Researchers say that the lung damage that constitutes COPD can't be reversed; all you can do is halt or slow the progression of the disease. And if you don't start treating it until you're already out of breath just walking around the house, you've got a lot less to work with. If you feel your ability to draw a deep breath is declining, ask your doctor to perform lung function tests to give you a clear picture of your lung health.
2) Frequent or worsening coughs:
Everyone gets a cough once in a while. But, if you seem to be getting them more frequently, or they linger for a long time or become chronic, it's time to talk to your doctor. COPD inflames the bronchial tubes and the tiny sacs called alveoli that line the lungs, making them less flexible and elastic. When that happens, the walls of the airways thicken and produce more mucus than usual, which clogs them up.
