Increased dose Levothyroxine Sodium

I have been Hypothyroid since 1999, I had no need for any change in dose until 2014 when my doctor at that time did not put my dose from 100mcg to 75mcg for nearly a year thus losing weight from 8st to 6st... As with all Covid restrictions I have not seen a Doctor since 2019 and when I was contacted for blood tests in May 2021 I asked them to include my Thyroid all tests came back normal apart from my Thyroid which was low, It was increased from 75mcg to 100mcg , up until the beginning of August I felt great, my blood pressure was good etc, for the past few days my hearts racing, I have high blood pressure again and feel tired all the time. I have rung doctors and was given a phone call appointment which hasn't happened so will ring again tomorrow. Have only been on them 3 month should I persevere.

Bloods should be retested 6-8 weeks after any dose change or brand change in levothyroxine

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis) diagnosed by high thyroid antibodies

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Is this how you do your tests?

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

If TPO or TG thyroid antibodies are high this is usually due to Hashimoto’s (commonly known in UK as autoimmune thyroid disease).

About 90% of all primary hypothyroidism in Uk is due to Hashimoto’s. Low vitamin levels are particularly common with Hashimoto’s. Gluten intolerance is often a hidden issue too
