s possible that the hair loss is related to or caused by fungus, and it sounds like when you are on
Biaxin/clarithromycin, the hair
loss gets worse. Hmmm. Cause==>effect? I also got very bloated when I had the systemic yeast infection, and your weight gain could be a similar symptom. Dunno.
Lyme can often mess with thyroid function; I was put on thyroid supplements for a while, but once I began to kick the Lyme, my thyroid sorted itself out, so consider that too.
