poolingHave you ever discovered that your free T3 lab result was high and/or over the range with continuing symptoms??

This phenomena is what we, as thyroid patients, call “pooling”. Pooling means your free T3 isn’t making it well to your cells, and instead, is hanging out in your blood, going higher and higher as you raise your T3-containing medication like Cytomel or natural desiccated thyroid. You may or may not know it’s happening at first. But sooner than later, pooling ends up promoting excess adrenaline and hyper-like symptoms as a result. It seems to also eventually result in higher RT3, we’ve seen, if patients keep raising NDT in the presence of low iron or a cortisol problem.

What are symptoms patients experience due to pooling, which pushes excess adrenaline? 

They are individual, but we noticed symptoms such as anxiety, panicky feeling, shakiness, heart palps, higher heartrate, higher blood pressure, etc.  Other issues can cause those excess adrenaline symptoms, too, but we do notice them when pooling, too.

What causes pooling?

For most thyroid patients, it’s because of two problems: inadequate levels of iron, and a cortisol problem, whether too low, or too high. Also accompanying pooling sooner or later, and if you are using Natural Desiccated Thyroid or T4 in your treatment, is rising Reverse T3 (RT3)–the inactive hormone that if in growing amounts, contributes to the “pooling” since it’s competing for the same cell receptors as T3, and blocking the door! T4 in higher amounts converts to RT3 if you have an iron or cortisol problem!

A high FT3 will also mean your RT3 ratio can look good, but it may not be!

Do pooling and a high Reverse T3 come together?

Not always. From looking at each other’s labs, some will see pooling first without having an excess of RT3. Later, if they continue to raise NDT, the RT3 dominance can occur.
