Hi Caz, check your ranges. Make sure your numbers are in the high end of normal ranges or a tad above, as this is where a lot of people do best on the meds.
It’s likely that the recent cold weather is wreaking havoc with your system. I know I’ve had to change things up with the icy cold weather recently. Many people find they need to increase their meds during the winter months and lower them as the weather warms up. I can tell you that thyroid management is much easier in a warm climate.
So, your thyroid does not function independently of the rest of your body and is in fact intimately linked to many functions and reacts to body functions to adjust your energy levels. More on this in a bit...
Keep in mind that levothyroxin is T4 only. So most people wind up with relatively high T4 and lower T3, though still in range. You tend to get T4 at the top end of the range and T3 at the low end with levothyroxin. There is a natural normal ratio in humans of T4/T3. Since the meds, levothyroxin, are T4 only, even if you’re converting well, your ratios will be low in T3. The normal human ratio is 14:1 T4/T3.
There is now a ton of research on ratios, so feel free to search studies as they’ve found various syndromes within thyroid disease to have various abnormal ratios.
Your body depends on the thyroid, gut and liver to convert to T3. Since meds bypass your thyroid, your levels will automatically be lower in T3.
You’ll likely do better with NDT if you’re low in T3. NDTs are from pigs and have a way higher ratio of T3/T4 than human. So you’ll get higher than normal T3/T4 ratios on the NDT. This also can throw your system off. However, NDT is closer in molecular structure to human thyroxin, since it is natural, which a more important reason to go with NDT. Either way, you’ll get a wonky T3/T4 ratio when you take meds because none match the natural human ratios: Levo results in too low T3, NDT is too high. The higher the dose, the farther you get from normal ratios, the more wonky your system becomes... and this can really mess with your adrenals. So it’s all circular.
Currently, the closest thyroxin to human T3/T4 ratios is bovine. However, there is no prescription natural bovine. It is available as a supplement called ThyroGold. There are other non prescription bovines available, but I’ve found the ThyroGold to be very good. You can order it online. It is effective for all levels if thyroid treatment, as my mother uses it due to thyroidectomy and is doing far better on the ThyroGold than anything else.
This ratio is super important, as T3 is the fast acting, short lived thyroxin that your body uses as needed fir bursts of energy. If you do not have enough T3, your adrenals must compensate and provide short bursts of energy. This leads to adrenal burnout. Though, many thyroid patients already have adrenal burnout before starting thyroid medication. Oddly, while the instructions for all thyroid meds dictate that patients should be tested and treated for adrenal disease prior to taking thyroid medications, no adrenal testing is provided in typical hospital settings.
In the end, if you have thyroid disease, you most likely have an adrenal problem. There’s a hormone book that I’ve found helpful that offers various levels of treatment options for endocrine problems. I’ve found this to be extremely helpful. The herbs work very well to rebalance things!
Many patients experience gut and liver problems due to thyroid disease (the levothyroxin is known to worsen gut and liver problems). I recently discovered that pancreatitis also results in a myriad of gut issues (and is heavily linked to liver and gallbladder function). With the cold weather, my system was super wonky as my thyroid levels were very low, and I could hardly eat anything. After some research, I tried a pancreatitis regimen, and found it to be extremely helpful. Hence, I suspect that both hypothyroid disease and levothyroxin cause pancreatitis stemming from low body temps and liver/gallbladder sluggishness. Once I got the pancreatitis somewhat controlled, it was a lot easier to tell what my thyroid symptoms were doing and adjust my thyroid regimen.
So yup, your system is wonky because of the cold. Yup, the meds can contribute to the wonkiness, and can make things worse, and it’s hard to tell what’s what, and your whole body is effected! Where to start!?
