Thyroid and the gut: Hidden health partners

Though I have personally dealt with both auto-immune thyroiditis (Hashomoto’s) and several gut issues (wheat sensitivity, gastritis, etc.), it was not until recently that I discovered how close the thyroid and gut work together to keep you healthy – and how problems with one can affect the other along with your overall health.
 
Most of us understand that the primary function of the gut, that 25 to 30 feet of “tubing” that includes everything from your stomach to your large intestines, is to process the food we eat and allow the “good stuff” (essential nutrients) to pass into our blood stream while keeping the “bad stuff” (harmful proteins) out. However, it may surprise some that the gut also holds as much as 70% of all the immune tissue in the body.
 
Now, imagine all the health havoc that could ensue if, suddenly, the gut stopped doing its job – particularly if it failed to stop toxic proteins from entering the blood stream and then mounted an overzealous immune response against them.  Sometimes, those overzealous immune responses reach beyond their intended targets to attack otherwise healthy tissues and organs – like the thyroid gland.
 
Recent studies indicate that thyroid hormones play a significant role in maintaining gut integrity, preventing leaky gut that can, in some cases, lead to auto-immune attacks against the thyroid.  A properly functioning gut also aids the production of thyroid hormones by converting some of the inactive “T4” thyroid hormone into the functional “T3” hormone.  Failure to simultaneously maintain both a healthy gut and a healthy thyroid can create a vicious cycle leading to chronic health problems and declining vitality.
 
What it all means is that to enjoy optimal health, you must promote good thyroid health to promote good gut health and vice versa.  Unfortunately, traditional medicine tends to focus on one issue to the exclusion of others.  A typical endocrinologist may treat your under active thyroid without spending a moment to address underlying gut issues.  A gastroenterologist will work alleviate a gut problem but will rarely address a potential thyroid problem.
 
This illustrates, once again, how our bodies work as a system and why it is necessary to bridge the “healthcare gaps” in traditional medicine by becoming personally responsible for your health.  I encourage everyone to consult the Cureality Program Guide and online Cureality Diet and Thyroid Health Tracks to learn more about how to optimize both your gut and thyroid health on your journey to realizing complete, whole-body health.

A stent--just in case

A stent--just in case

Burt came to me last week. He'd received a stent a few months earlier. He'd been feeling fine except for some fatigue. A nuclear stress test proved equivocal, with the question of an abnormal area of blood flow in the bottom (inferior wall) of the heart.

"The doctor said I had a 50% blockage. Even though it wasn't really severe, he said I'd be better off with a stent, just in case."

Just in case what? What justification could there be for implanting a stent "just in case"? (The artery that was stented did not correspond to the area of questionable poor blood flow on the nuclear stress test.)

Just in case of heart attack? If that's the case, what about the several 20 and 30% blockages Burt showed in other arteries? The cardiologist was apparently trying to prevent the plaque "rupture" that results in heart attack by covering it with a stent. Why stent just one when there were at least 7 other plaques with potential for rupture?

That's the problem. And that's why stents do not prevent heart attack (unless the stent is implanted in the midst of heart attack, when the rupturing plaque declares itself.) Of course, when no plaque is in the midst of rupturing, as with Burt, there's no way to predict which plaque will do so in future. Since only one plaque was stented, there is a 7 out of 8 chance (87.5%) that the wrong plaque was chosen. And that's assuming that there aren't plaques not detected by catheterization angiogram; there commonly are. The odds that the right plaque was chosen would be even lower.

In other words, stenting one blockage that is slightly more "severely blocked" in the hopes of preventing heart attack is folly. If it's not resulting in symptoms and blood flow is not clearly reduced, a stent can not be used to prevent plaque rupture. A stent is not a device to be used prophylactically. It is especially silly when an approach like ours is followed, since plague progession is a stoppable process.

Note: This issue is distinct from the one in which symptoms and/or an abnormal stress test show clearly reduced blood flow and flow is restored by implantation of a stent. While some controversies exist here, as well, a stent implanted under these circumstances may indeed provide some benefit.

    Interesting blog.  I have a question: would you be able to offer some comments on Dr. Ornish reversal programme and low fat vegan diets (in reversing CHD), based on your professional experience?

    We are having a little discussion about various pros and cons of various therapies and dietary approaches on the Web MD forum:

    We would really welcome you and would greatly appreciate some professional comments.  Sincerely,

    Super low-fat diets, while an improvement over a conventional modern American diet of high saturated fat and processed foods, seriously exagerrate the small LDL particle pattern that is among the most powerful causes known of heart disease. It also reduces HDL and raises triglycerides, sometimes substantially. Dr. Ornish would argue that these are inconsequential changes, since his patients regress. Unfortunately, the methods he uses to gauge regression of atherosclerotic plague are flawed: angiography and nuclear imaging. Both can be envisioned as measures of flow, not of atherosclerotic plaque. Only CT heart scans or intracoronary ultrasound actually measure artery plaque. I tell my patients that, if you want heart disease, follow the American Heart Association diet. If you want heart disease and diabetes, follow Dr. Ornish's diet.

    I know several people who have gone for a "routine" check with a cardiologist, sent for an angio, and ended up with at least 1 stent. (NO symptoms prompted these visits, just "high cholesterol".

    I also know a couple of people that have 9, 10, or more stents!
