Has RSV. Gets Pneumonia, Chronic Coughs, Chronic Upper Respiratory Infection. Possibly SCID, Leukimia?
Thanks for posting your query.
According to studies, 50% of children suffering from recurrent respiratory infections are normal but others may have.
1.some atopy or allergy (30%) causing asthma, bronchitis, hyperreactive airways.
2.A chronic disease (10%) like congenital heart disease, gastroesophageal reflux and chronic aspiration etc or
3.Some immunodeficiency(10%) either primary or congenital or secondary like malignancy etc
So all of these are possibilities and a confirmation of the diagnosis with complete physical examination as well as blood tests, xrays etc.
According to the age and history of past illnesses , the presence of chronic ilness or immunodeficiency can be the most probable diagnoses. Since asthma usually has other pointers of allergic rhinitis, sinusitis etc. Primary immunodeficiency disorders usually present between 7_12 mths and runs in families.
Chronic illness or heart defects can cause all the mentioned symptoms and can be picked up by your pediatrician on auscultation and examination
Your doctor is right in ordering the tests since the persistent or recurrent infections can significantly decrease the growth and development of your child.
Meanwhile you should improve the childs nutrition by giving wholesome homemade meals with vegetables, fruits and plenty of water/ fluids. This prevents dehydration, and anemia/ vitamin
deficiencies.
If the cause is evident then your doctor can further manage the illness accordingly.If cause remains undiagnosed then most likely it is part of development and as your child's age and immunity increase they are likely to resolve.
Hope I have answered your query. Please write back if you have any further queries.
Wishing you good health.
