I am concerned about my 15 year old niece...she is experiencing several symptoms: loss of hair, excessive thirst, excessive weight gain, & chronic problems with her tonsils....a few years ago, she lived in a very old house (I suspect that it may have had mold or mildew)....and now, the current house in which she lives, may have some mold as well. I am quite sensitive to mold myself so I detect it when I m exposed. Could mold have caused her problems or is there another underlying issue here?
