Is the use of this medicine(steroid) effect him in long run? what are the diagnosis which can be done, as his general physician says he has Childhood Asthma.

### output:

Hello, thanks for posting on Chat Doctor, I understand that this must be a very troubling situation for your. But what you need to understand is that the underlying causes of childhood asthma are not fully understood by the medical community. Developing an overly sensitive immune system generally plays a role. Some factors thought to be involved include:- Genetic inheritance- Certain childhood respiratory tract infection in early childhood- A child who is exposed to certain extreme environmental factors such as cigarette smoking.  Increased immune system sensitivity causes the lungs and airways to swell and produce mucus when exposed to certain triggers. Reaction to a trigger may be delayed, making it more difficult to identify the trigger. These triggers vary from child to child and can include:- Viral infections such as the common cold-Exposure to air pollutants, such as tobacco smoke-Allergies to dust mites, pet dander, pollen or mold-Physical activity-Weather changes or cold sometimes, asthma symptoms occur with no apparent triggers. As child will get matured, his lungs will become much more mature and the frequency of crisis will be less but that does not mean that the asthma has been dissolved. You will need to know that asthma is a chronic condition and only requires child being on regular treatment. I do not think that being on low dose corticosteroid will not be of any harm to your child and other medications (such as bronchodilators) will be used instead to replace the steroid. Hope this helps
