I just wondered why people changed from a combination of T4 and T3 to T3 only? Do you feel better or different? And how does it affect your blood tests doing this?
If you are hypothyroid and take T3 only - what in your body produces the T4 to show up in a blood test? As presumably your thyroid isn't working so cannot produce T4? Or does the thyroid partially work and so produces some T4?
