Lisa, re: the question about hypo vs hyper thyroidism there exists primary
and secondary hypothyroidism. Secondary hypothyroidism is caused by pituitary
causes and can occassionally cause decreased TSH Levels.T3 and T4 are the
thyroid hormones . These are produced and secreted in response to TRH and
TSH, which are regulated by the hypothalamus and TSH from the Anterior
Pituitary. TRH regulating the secretion of TSH which directly increases or
decreases the production and release of T3 and T4. The effects of TSH can
occur in 30 mins where the other responses take days or weeks.This I obtained
from an excellent lab reference book  I have. It would look like hyperthyroid
perhaps because when T3 and T4 are increased in the blood stream TSH levels
decrease, except as the reference book said , occasionally , in secondary
hypothyroidism, TSH levels can be decreased. What sx does she have besides
the low milk supply? Lisa Mooney, RN, BSN soon to be IBCLC
