I have had symptom consistent with hypothyroidism and had the TSH and free
. The TSH is normal but my free T4 is low...what does this mean? I have seen some literature on the net that sometimes the free T4 can gradually decline and the TSH and suddenly go up, therefore indication of hypothyroidism. My symptoms are weight gain, not able to lose weight, constipation, depression, lack of libido, memory problems. Any help?
