Respiratory issues in a 50yo athlete

[vmi84]

I'm a 50yr old ultra distance athlete who's noticed a perceived reduction in lung volume.  Instead of always being able to take in the deepest breath possible (95+%), I typically experience a slight constriction (85+%) of lung volume.  

I've changed my diet thinking food sensitivities or alergies were the cause, but the symptoms still remain.  I've also had two spiriometery tests and was evaluated as having some level of blockage, but nothing more.

My concern is being in the early stages of some condition which could be manageable, but if it goes unrecognized could become debilitating or worse...thanks

Have they specifically checked you for Exercise Induced Bronchospasm? (standard spirometery does not cover  this) And, have you noticed if cold air or humidity changes influence any of the reductions?  One of the E.I.B. tests uses spirometery tests in conjunction with albuterol as a comparator, the second test may vary depending on the doctors methods.

Hello and hope you are doing well.

You symptoms could also be due to Small airway disease, which affects the respiratory bronchioles. Disease of small airways results from exposure to tobacco smoke, mineral dust, air-pollutants, and viral infections. It may also be associated with connective tissue disorders. The pulmonary function tests are abnormal only late in the disease and the damage done is irreversible. Therefore, management lies in preventing exposure to smoke and dust, whether in the form of smoking tobacco or exposure to industrial dusts in the work environment. Check with your doctor to rule out this condition.

Hope this helped and do keep us posted.
