this has been happening for 2 years in a row now. Could only tell by symptoms last year but this year I tested every 2 weeks and sure enough its happening again.
Last year I was started on thyroid medication. From mid may I was on 4 grains NDT. This continued for almost a year. The first few months up till August every symptoms was taken care of. Cone September everything gets worse. Turns out thathat where my 4 grains first brought be to the top of the range for t3 and t4, they dropped. Up till the winter and spring my t3 was never more than 4, t4 as low as 11.
At a review in may I was put on 6 grains and again, my levels finally get top of the range: t3 6.2, t4 20.
I got these numbers from june onwards until the last test on the 23rd of august.
I test again on the 5th of September and still on 6 grains, taken the same waway at the same time, my t3 has now dropped to 4.2, t4 to 17.
Has anyone noticed such marked seasonal changes and what have you done to manage? Thanks so much
Ps: I dont have hashimoto, just dio1polymorphism so cant convert
