What Causes Difficulty In Breathing While Exercising?

Just got routine bloodwork done and I have low MCHC. I am a very active, relatively fit 42 year old female. My cardiovascular performance is not improving like I would like but I was a smoker for many years. Wondering if the low MCHC could contribute to difficulty breathing when running. Or if it could be an indicator of early stage lung cancer.

Pulmonologist,  's  Response
Thanks for your question on HCM.
I want to ask few questions.
1. Wahat is your hemoglobin level.
2. What is MCV level.
If both of these are low along with MCHC than you are having iron deficiency anaemia.
If both of these are normal than we need to rule out cardiac and pulmonary causes as you had smoking history.
So get done ECG and 2D Echo to rule out cardiac causes.
Get done chest x ray and PFT (Pulmonary Function Test) to rule out pulmonary causes.
Inmy opinion you are having bronchitis rather than lung cancer.
So get done above mentioned investigations.
I find this answer helpful
