Hello im a female and my thyroids are always a little low but other times way low but my doctor will not perscribe me on meds what do i do?

Second opinion: Are your thyroid low by symptoms or on labs or both? If you don't agree with what your doctor is doing, seek a second opinion by another board certified physician or a specialist.

Get a second opinion: He may be wrong or what you call little low may not be 'significant' clearly md and patient need to communicate better- so see ask him to explain more precisely, or see someone else.
