I am a 39 year old man, Smoker, weight 63KG & height 172 cm I fell always a mild shortness of breathe from the last 02 month. My doctor makes me the, Chest x-ray, 6 minute walk test, allergy test & a bronco provocation test. My chest X-ray, 6 minute walk test is quite normal. But my bronco provocation test result is 1) moderately restrictive airway defect. 2) Moderately positive bronco provocation test. My baseline/ pre-medication FVC are 61% & FEV1 is 61%. FEV1/FVC ratio is 82%. (My doctor prescribed me the medication, Seretide 250 Accuhaler, MONTELUKAST 10MG, Ebastine ,
MY question is: 1) is it possible to increase The FVC % till to normal range? As I can see it is lower than normal 80%, which indicates restrictive lung dieses. 2) Is there any treatment to stop the decline of FVC% 2) do I require further more investigation? 3) How severe my situation is according the above mentioned info? Do I need further more diagnosis?
