Thanks for the query to H.C.M. Forum.
Molds are aeroallergens that can trigger significant asthma
symptomsin both seasonal & perennial fashion.
Molds are tow types usually as,
1 Outdoor molds &
2 Indoor molds.
Here we concern only about indoor molds as you stated in your query that you are living in house with black molds from the last 4 years.
Two most important molds are as,
2 penicillium ( also known as MILDEW) usually this is in black color over the walls of house where damp and moist climate present, as in bathroom and in kitchen walls.
Water seepage and humidity increases the effects of these molds over health.
When any persons resides in these type of house , naturally with inhalation these molds enter into lung with airflow through mouth and nose.
They develops allergy
This lowers the immunity of patient and other many more diseases develops.
ALLERGIC ASTHMATIC BRONCHITIS
is one of the most important disease.
If one patient suffers for 3-4 months in a year for three consequent years , patient develops C O P D ( CONGESTIVE OBSTRUCTIVE PULMONARY DISEASE
) , this leads to fibrosis
in lungs and more many diseases.
Child are more prone to these allergy and later on infection ( as in your child case). Respiratory disease causes gastric problems as in your child.
Immunity diminishes , narcolepsy
phleboliths are common associated with these disease.
Hope I have answered your query.
If further any question I will help.
Good luck. Dr. HET
