Thanks and Regards.. [/INST] Hello, Thank you for asking at Chat Doctor. I went through your sons history and would like to know more about him as follows:a. What is the frequency of his wheezing? Any seasonal variations?b. What are his nose symptoms - running nose, congested nose, sneezing, etc.?c. Does he cough more during day or night’d. Does he vomit or often nauseate?e. Does he have gastric disturbances like constipation, frequent stomach pain, frequent diarrhea, etc.?f. Did he have any skin problems/allergies since birth?g. Does any of his family member have allergies? Above details would help me to know more about his health and therefore to make suggestions more specifically for him. At present, from your provided details, I would like to make suggestions for him as follows:1. As long as Tb and other chronic lung diseases are concerned, I would think about them only if he is almost always sick, he does not respond to nebulization and other medications, he has serious weight loss, etc. If he does not have above features, I would not think of any serious cause.2. Wheezing is very common in this age and there are many causes like allergies, viral infections (including bronchiolitis), gastroesophageal reflux disease (HERD), childhood asthma (non-allergic), etc. So detailed history is important before suspecting a particular diagnosis and suggesting any investigations.3. I usually prescribe my such patients regular montelukast + levocetirizine which helps for most symptoms. If he develops wheezing, I suggest them nebulization with albuterol or levosalbutamol on as-and-when-needed basis.4. Cold air, cold Chat Doctor. 5. Also, please avoid exposure to dusts, smokes and air pollution as much as possible.6. It is usually true that around 70-80% of the child </s>
