I have been suffering with hypothyroidism for many years. Despite taking levothyroxine my TSH has been steadily rising and symptoms getting worse as I get older even though my GP has kept increasing my dose. I queried whether it would be worth testing my T3/T4 to find out if there might be a problem in conversion but the consultant that my GP wrote to said this was unnecessary and to buy myself some selenium tablets if it would make me feel better. My TSH has come down in last weeks blood test but is still the high end of normal, which is best I ever seem to get with it yo-yo-ing borderline / high. I'm on 250mg Levothyroxine daily and have been told I need to increase this by 50% should I become pregnant. We would like to start a family but my question is should I bottom out what my stable dose is before considering starting a family as I can't be sure that mine is being well managed? - I still experiencing severe symptoms: Weight gain, Slowed thought and speech, increasing Pins and needles (left arm - My rheumatologist is checking if this could be caused by my Rheumatoid Arthritis), Loss of libido, Dry eyes, Dry skin and Constipation. I know how severe the effects of insufficient thyroxine is on fetus so I am very keen to get some advice on whether I should be pushing for a second opinion, and if so how to go about it?
