I had a ct scan to follow up on lung nodule which came back no change after 12 years and most likely from previous infection or inflammation.

That was good news. However scan showed some lung hyperinflation and bronchial thickening. No emphysema noted and no bronchiost.


I had asthma when I was young and am 64 years old. No symptoms. I exercise regularly with no issues.

Is this something I need to be concerned about?

I am wondering if asthma typically involves restrictive or obstructive airway problems, and if the following spirometry data is indicative of asthma, COPD, or some other breathing difficulty condition: (1) 11/02/2016. FEV1/FVC 0.55, FEV1 50% predicted; (2) 12/16/2016. FEV1/FVC 0.66, FEV1 72% predicted; (3) 01/09/2017. FEV1/FVC 0.64, FEV1 83% predicted; (4) 05/16/2017.

Hello, In November after visiting gym I ve got stuffed and 100% plugged nose, later developed chest caugh, pain, tiredness, thought I might have had pneumonia.. Took a lot of rest, lung teas, herbal tinctures, veget. and fruit juices etc. Lung Xray was OK. 2 weeks of antibiotics didn t clear it up. Up to now having smelly yellowish mucus coming out of my Bronchi s. Much worse after any kind of small walk, excercise. I am very concerned, it feels like infection in my chest that is not going away. Dr. ordered spirometry and metacholine tests, that suggested mild Asthma. Recommended cortison puffers only. I gave sample of yellow mucus - came out as inflamation only. What should I do next? So far I stayed off work last 3 months, taking care of myself, it seems getting slowly better until I go for a little walk when symptoms come back big time. What other test should be done to find out the real cause? I feel, that if it is not cleared, it will be getting worse over time. I used to do a lot of sports here as well as in Europe since childhood, until 3.5 months ago, and I am very worried about the future of this medical issue. Thank You, Radka

Hi, may I answer your health queries right now ? Please type your query here...just got the results of my pft, the interpretation is: forced vital capacity,fev1 are decreased. Tvci is normal. mmfr is normal. tlc is normal. thoracic gas volume is normal. Diffusion capacity is decreased to 55%, Airway resistance is decreased. Specific airway conductance is increased.
Impression is: Mild combined ventilatory defect obstructive and restrictive,primarily obstructive lung disease with some restrictive component. Moderately impaired gas exchange mechanism. suboptimal post bronchodilator improvement.
Please explain what all this means and is it asthma or emphysema.
