Hello.
Thank you for asking at HCM.
Most of the
childhood asthma improve with age and subside by 7-8 years as told by your doctor. However, exact age at which the child will be alright cannot be told and of course, some children do not improve and continue to have asthma.
So if your son's asthma has improved over years (that is, he is having fewer attacks of asthma than he used to have before, or he is requiring fewer doses of inhaler medicines that he used to require before), I would not worry.
However, if his asthma has not improved as suggested above, I would think he may have an
allergic asthma which continues into adolescent and adult age. In such case I would suggest you to consult an Allergist-Immunologist who will after detailed history taking suggest your son
allergy testing, which is necessary to know what he is allergic to.
Breathing exercises & avoidance of amoke-dust-air pollution will help him a lot improve his asthma.
Regarding
stammering, it is a
speech disorder and is not directly related to asthma. However, psychological issues such as low self-esteem (which may be due to having asthma) can contribute to stammering. I would suggest you to stay positive towards him, encourage him and get a help from a speech therapist who will suggest some speech exercises for stammering.
Hope this will be helpful to you.
Wish your son the best of the health.
Regards.
