My endocrinologist stopped my 5 mcg of T 3 a few months ago to see if T 3 was causing palpitations.!now I am on increased dose of t4, levothyroxine 75mcg 3 days a week and 50 mcg 4 days a week both first thing in the morning on empty stomach.
Should I restart taking T 3 again ? Endocrinologist says blood work better without T 3. I don’t think stopping T 3 made much difference to palpitations, even though they are better after I stopped.
I got a sty on my eye, not sure if it’s related to my not talking T 3?
Any one know connection between sty and T3? I had cataract surgery years back and have glaucoma.

A stye happens usually because the immune system has become run down with impaired defence against the stye causing bacteria. This can happen when thyroid hormones are not adequate enough for well-being, ie alleviating all symptoms.
Endos freak when we suffer heart issues because elevated thyroid hormones will increase heart function and can be dangerous. However, the heart has a huge requirement for the right amount of T3, and I suffered AF & atrial flutter when medicating Levo alone which stopped when a little T3 was added to my meds.
Blood work only looks better to endo because they often aren't used to the different presentation of T3 labs. If you felt improvements medicating a little T3 then you need it and should medicate it. If it made no difference then the ongoing supply worry and fights with doctors probably isn't worth it.

"The major effects of thyroid hormones on the heart are mediated by triiodothyronine (T3). Indeed, T3 generally increases the force and speed of systolic contraction and the speed of diastolic relaxation. In addition T3 decreases vascular resistance, including coronary vascular tone, and increases coronary arteriolar angiogenesis'.
Low supplies of T3 can cause high diastolic known as diastolic hyertension. Not every organ has good conversion abilities and the heart is particularly reliant on a good supply of T3.
I’ve been trying to find you a paper that evidences this, and this isn’t great as is more about heart failure due to left ventricle abnormalities but it looks at other causes and clearly states;
‘Low thyroid hormone levels are associated with both systolic and diastolic dysfunction. However, both basic and clinical studies highlight that in hypothyroidism the diastolic abnormalities predominate’.
‘Cardiovascular risk factors are amplified in patients with overt hypothyroidism, particularly diastolic hypertension and dyslipidemia’.
When I first was prescribed levothyroxine, I had severe palpitations - especially during the night and I had many 'overnight heart checks'.
The cardilogist was puzzled and was contemplating putting an 'implant in heart' to see what was going on. Just then T3 was added to T4 and palpitations reduced but when I took T3 only, palps resolved altogether and I haven't had problems since with heart.
When first diagnosed (by myself after GP phoned to tell me all my results were fine) I was prescribed levothyroxine. GP didn't understand what a TSH of 100 indicated.
I had severe palpitations with levo and when T3 was added to T4 palps reduced but when I stopped T4 all pals resolved.
I now take T3 only as I was diagnosed as having a rare condition called Polyglandular Autoimmune No.3. as I have Hypothyroidism, pernicious anaemia/alopecia.

From hypothyroid to hyperthyroid. Is it possible?
New GP agreed to trial extra 25 mcg of T4 - advice urgently needed please (heart palpitations, sweating but good digestion?)
Reduction in meds due to palpitaions
Should I reduce levothyroxine due to palpitations?
