Hello. Thank you for asking at HCM. I went through your history & investigations and would like to make suggestions to you as follows: 1. Cough/breathing problem with weather change usually indicates allergic cause. 2. I would like to know more details about you like - do you have nose symptoms like running nose, nasal congestion, sneezing? do you ever had wheezing? What is the frequency of your episodes? Are you able to carry out your routine activities? 3. In reply to your query - Do I have asthma? - I would like to say that you can possibly have asthma. I would suggest you spirometry with post-bronchodilator reversibility test to confirm the diagnosis of your respiratory disease. 4. Were I treating you, I would suggest you to take montelukast regularly as well as salbutamol/levosalbutamol inhaler on as-when-needed-basis for when you experience breathing difficulty. 5. I would suggest you allergy testing which will help you identify the substances you may be allergic to. It will also help you to know how to avoid the substances exposure. 6. In general, I would suggest you to avoid exposure to dusts, smokes and air pollution as much as possible. 7. Regular breathing exercises and a healthy diet rich in vitamins & minerals (adequate amounts of green leafy vegetables, fruits, sprouts) will help you in longer run by improving lung capacity and immunity respectively. Hope above measures will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
