I've recently had to switch from T3/T4 to T3 alone. Trying to raise T4 resulted in an increase of hypo symptoms.
On 25mcg of T4 and 37.5mcg T3 my bloods were:
TSH 0.08 (0.3 - 6.5) FT4: 8.4 (9 - 2.5) FT3: 4.7 (3.5 - 6.5)
Prior to this I was on 75mcg T4 and 20mcg T3
TSH: 0.01 (0.27 - 4.20) FT4: 17.9 (12.00 - 22.00) FT3: 5.2 (4.00 - 6.80)
Every time I try to increase the T3 I get slow hard palps. If I reduce the T3 then the palps subside. If I stay on the increase the palps get worse daily.
I'm not low in iron and vits etc. are good or I supplement. Cortisol levels are good.
I have to come off of T4 as I think it has built up in my body and is not being utilised. Many hypo symptoms occurring.
I have given blood levels but does not really show what is going on in my body. Bloods look good with T4 but I am very hypo.
