Has medic explained to you that you have Hashimoto's- also called autoimmune thyroid disease

Your antibodies are very high so this confirms Hashimoto's, (also known as autoimmune thyroid disease). About 90% of hypothyroidism in UK is due to Hashimoto's.

How long since you stopped T3. How much were you taking before

Hashimoto's very often affects the gut, leading to low stomach acid, low vitamin levels and leaky gut.

Low vitamins that affect thyroid are vitamin D, folate, ferritin and B12. Important to test these. If they are too low they stop Thyroid hormones working. Have these been tested, if not ask that they are. Always get actual results and ranges.

Very important to correct low vitamin levels first. Some of your symptoms are likely due to this

Post results if you have them

Also with Hashimoto's then hidden food intolerances may be causing issues, most common by far is gluten. Changing to a strictly gluten free diet may help reduce symptoms. Very, very many of us here find it really helps and can slowly lower antibodies.







I stopped T3 in June and above results done start of September this year. I was taking 5mcg of T3 twice a day. I didn't know I have Hashimotos. Don't know where to start with vitamins and minerals, I have all sorts of different things at home thinking they help but I am lost with what to take and when.


Ask GP to test vitamin D, folate, ferritin and B12

If you have not been taking any B vitamins do NOT start now, or results will be not true.

Selenium recommended with Hashimoto's and vitamin C you can take to support adrenals.

Low B12 - can be cause of tinnitus

Heavy periods likely to cause low ferritin


Hi they were tested 2 weeks ago, is that recent? I know what results are


Yes post now - either here or on new post
