Overwhelmed with thyroid information? Trust me, I get it. There is SO much to know about the thyroid that you may find yourself getting a serious case of paralysis by analysis– especially if you’re taking your meds like you’re supposed to and STILL feeling crummy.
Here are some of the most important basics you need to know about your thyroid health:
1. The thyroid produces two main thyroid hormones:
T4: ~80% of production, but relatively inactive. It must be converted to T3
T3: ~20% of production. MUCH more bio-active. Produced predominantly from T4 converting into T3.
Note: there are other thyroid hormones, but these are two are the most dominant and abundant!
2. The T4 to T3 conversion doesn’t always happen as expected.
The T4 to T3 conversion (AKA inactive to active) is a critical step in mastering your hypothyroidism and all the symptoms that come along with it. The conversion is highly impacted by:
3. The most common prescription for hypothyroid is Synthroid (or Levothyroxine) which is T4 only.
This is often sufficient enough thyroid replacement for many, but if you’re having issues converting your T4 medication to T3, you could still be experiencing all the symptoms of hypothyroidism despite taking your meds regularly. If this is you, consider getting a FULL thyroid panel that includes both Free T4 and Free T3.
4. TSH (thyroid stimulating hormone) has an inverse relationship with your thyroid status.
This means the higher you TSH, the more hypothyroid you are. TSH is a brain derived hormone that increases when it identifies that circulating thyroid hormone levels are too low in the body. TSH is a marker of thyroid status, but just ONE marker… and not always the MOST helpful marker. Here is what a full thyroid panel looks like!
5. The best way to determine if your root cause of hypothyroidism is to test antibodies.
If you’ve never had it done, it’s worth checking “Anti-TPO” and “anti-TG” to see if autoimmune disease is the reason you have hypothyroidism. While it may not necessarily change the course of action with your medication, this is empowering information to see how you can best manage your disease progression.
