Suggest Treatment For Asthma, Seasonal Allergies, Tiredness And GERD

My daughter is 46. She is suffering with hair loss, asthma, seasonal allergies, GERD and her teeth are even chipping. She had allergy tests which revealed only the seasonal allergies. The Dr said she had asthma brought on by GERD. She looks and feels tired all the time. She has always been very health conscious, eats right, works out an hour every morning, does not smoke and drinks only wine very moderately...I m very worried and would like to give her some guidance regarding what type of Dr she should see next.
