can candida cause hypothyroidism??? My doctor tested me for this, and in fact she said I have this and now have to take something called NatureThyroid. It's no big deal, I have none of the symtoms of hypothyroidism so I can just take this stuff which is easy with zero side effects. My sister has the hypothyroid thing too, she's 52, I'm 50 and just says it is really common in women this age. She doesn't have the candida though. I have the candida which stemmed from parasites, not Antibiotics .
