<s>[INST] i am a bronchial asthma patient of 52 years of age.  I am asthmatic for the last 16 years.  Doctor had prescribed Foracort inhaler for daily use which I am not using.  Nowadays,   I feel breathlessness even after running for 50 mtrs slowly.  Am I suffering from Lungs Fibrosis ? Please advise [/INST] Hi. I can understand your concern. Asthma is most common allergic disease which is not a curable disease but definitely controllable, by controlling the same you can lead a symptom free life. Usually presents with cough, wheezing, difficulty breathing and chest tightness. If not treated appropriately can be life-threatening. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test). PFT is needed for the diagnosis of asthma. It will also tell you about severity of the disease and treatment is based on severity only. You may need inhaled bronchodilators and inhaled corticosteroid (ICS)Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks. </s>
