WHY ARE YOUR THYROID LABS FLUCTUATING?
This could definitely be annoying, especially when it’s high, then low, then normal, and your practitioner just acknowledges the normal range and says “Oh, you’re back on track, nothing to worry about” and forgets about it.
.
Thyroid fluctuation can sometimes be normal, but not to the degree that markers exceed out of the optimal range and there’s a possible diagnosis. In many cases, it is a stress on the body, but exogenous sources can also influence the numbers. Here are a few below:

1️⃣Stress in itself can cause thyroid hormone to fluctuate. Whether this is mental, physical or environmental, the nervous system will kick in and signal to the thyroid to either slow down or pick up pace.
2️⃣Time of day. In the morning our numbers should be pretty average, but they rise by mid day, and then slowly dip back down at night for when our bodies know we won’t need as much energy.
3️⃣Natural supplements: Things like biotin, tyrosine (which is an amino acid that helps convert thyroid hormone),  iodine (or natural sources even like kelp), or herbs such as guggul or bladderwack can affect one’s thyroid levels causing it to seem overstimulated, or in some rare cases suppress it.
4️⃣Medication can also affect lab markers such as not having the proper dosage of Synthroid, cholesterol lowering drugs like statins, corticosteroids affecting the HPAOT axis, hormone replacement therapy (especially if the dosage of estrogen is too high, suppressing thyroid function), as well as antidepressants or SSRIs.
5️⃣Lastly, sometimes alternating thyroid markers is a sign of autoimmunity developing, particularly Hashimoto’s, which is a condition in which your immune system starts “attacking” the thyroid in itself.
