I don't think you had a TT in August 2019 and RAI in October 2019, it's only July 2019 now.

Don’t know why I am losing weight

The answer to that may depend on certain things.

Were you overweight before?

Is the weight loss alarming?

Were you on Levo only before and overweight?

How long have you been on T3?

Has the weight loss started since being on T3?

What are your current levels for TSH, FT4 and FT3?

When we are hypo and on Levo only and weight loss is difficult, it's generally because our FT3 is low, often due to poor conversion of T4 to T3. Once we optimise our thyroid hormone replacement and we have enough T3 then we can often shift stubborn weight.

Ha. Thanks. Little man had me up all night. Yes 2018

I did start on levo only and weight started to drop off after rai in Oct

I do have a problem connecting to T3

Started T3 May 19

I did wonder it’s because of the T3 that I am losing weight. Just a worried about cancer

Suggest you get bloods retested, making sure to leave correct timing on T3 and Levothyroxine before blood test

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Last Levothyroxine dose should be 24 hours prior to test,

(taking delayed dose immediately after blood draw).

If/when also on T3, make sure to take last dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test

What vitamin supplements do you currently take?

[dodge1979 in reply to SlowDragon]

Thanks no vits. Stopped. Them all

[SlowDragon Administrator in reply to dodge1979]

Then you probably need to retest vitamin levels soon

Many people on Levothyroxine find vitamin levels drop if don't supplement regularly
