Hyperthyroidism occurs when the thyroid gland makes an excessive amount of thyroid hormone. This situation is often known as overactive thyroid. Hyperthyroidism hurries up the physique’s metabolism.

What Causes Hyperthyroidism?

Within the holistic world, we see that the 2 commonest root causes for hyperthyroidism are continual stress and/or toxicity within the physique.

Additionally, the foundation trigger relies on which degree is excessive or low, so let’s check out these:

If TSH is low:

First, let’s clear up one thing vital. TSH shouldn’t be a thyroid hormone. It’s truly a pituitary hormone. So a low TSH doesn’t mechanically imply your thyroid hormones are excessive.

Right here’s the way it works. Your pituitary, hypothalamus and adrenals (collectively they’re referred to as the HPA axis) are all a part of your endocrine system. They discuss to one another all day lengthy. When your physique is beneath continual stress, the hypothalamus tells the pituitary to decrease TSH. This indicators the thyroid to make extra hormones so your physique can sustain.

So a low TSH doesn’t at all times level to a thyroid drawback. Many instances, it’s actually an imbalance within the HPA axis. Your practitioner’s job is to dig deeper and discover out why that imbalance is there within the first place.

If free T4 is excessive:

• Most frequently, free T4 is excessive as a result of there’s a extreme type of emotional or environmental stress (from issues reminiscent of artificial pesticides, poisonous heavy metals, and probably glyphosate).
• FT4 may also be elevated as a result of TSI is mimicking TSH and telling the thyroid to make extra FT4. This typically occurs when one has Graves’ illness, so it’s at all times vital to get this degree examined.
• There may be additionally a adverse suggestions loop between TSH and FT4, so generally FT4 might be elevated when TSH is just too low.
• Free T4 may also be elevated in the event you occur to be on an excessive amount of thyroid hormone alternative, so it’s at all times good a good suggestion to speak to your physician or pharmacist about this risk.
• fT4 might be elevated from overactive thyroid nodules.

If free T3 is excessive:

Listed here are just a few the reason why FT3 might be too excessive:

1. The thyroid is making an excessive amount of T4 that’s being transformed to FT3.

2. When there’s toxicity someplace within the physique, this will improve FT3.

3. Being on an excessive amount of thyroid hormone can even trigger elevated FT3, so it’s at all times good to speak to your physician or pharmacist about this risk.

Don’t ever assume that simply because thyroid hormones are excessive that TSH is low, or that if TSH is low that thyroid hormones are excessive. Testing is at all times essential so that you and your practitioner can see the larger image.

Right here is the listing of thyroid labs to ask your practitioner for (or you possibly can get them organized your self right here):
