What thyroid patients should know about Oxidative Stress

20130817_151332With a recent Italian study hypothesizing a significant correlation between T4-only levothyroxine use and lung cancer because of “oxidative stress” (possibly due to the serum peak of T4), or the same oxidative stress simply from the hypothyroidism itself, it spurs curiosity as to what oxidative stress is about and what we, as thyroid patients, can learn from this biological phenomena!

Oxidation–what the heck is that?

I have a shampoo holder that hangs from the shower nozzle, and to my dismay, it started to rust underneath the coating. (Note to self: don’t buy a hanging shampoo holder from a garage sale, even if it does look brand new).  And this rust is an example of “oxidation”, i.e. when the iron comes into contact with oxygen (also via moisture), an oxidized corrosion will form called “rust”. Other examples of oxidation are the greenish patina you see on copper, the fading of paint on your house, or the brown coating you’ll see on an exposed cut apple…all due to the substance coming in contact with oxygen.

In your body, oxidation is a constant and normal chemical reaction going on every hour, every day and occurring when your cells come into contact with oxygen. It’s a required process to supply your body and all its cells with energy. Oxidation helps your body to get rid of old cells in favor of new cells. Your immune system also uses oxidation to attack and kill off pathogens.

Biologically, oxygenation describes the process of any particular molecule (which is made up of connected atoms) coming into contact with oxygen (making it an “oxygenated molecule”), resulting in the loss of an electron–a subatomic particle with a negative electric charge that surrounds any of those atoms. This oxygenated-molecule-minus-an-electron will frantically try to connect with another molecule which does NOT have this electron loss, and this constant attempt of connection produces an unstable “free radical”. And free radicals can cause all sorts of havoc.

Fortunately, a healthy and balanced body has a built-in ability to keep these unstable free radicals in check with anti-oxidant defense mechanisms…or at the very least, slow the havoc of a free radical down. Those heroes include several anti-oxidant enzymes, also called free radical scavengers, which can neutralize all those frenzied free radicals. Our body will also use nutrients in what we eat to squelch those free radicals, such as Vitamin C and E. Our bodies have the ability to repair DNA and tissue damage from free radicals, as well as zap damaged cells to death!

When Oxidation become “Oxidative Stress”

On the negative side, sometimes your body can lose the ability to take care of all the free radicals caused by the constant oxidation. (Collectively, all these free radicals are called “reactive oxygen species” (ROS).) The body then becomes overwhelmed by the excess of oxygenated free radicals, causing all sorts of damage. And this is all termed “oxidative stress”. 

Alarmingly, oxidative stress can cause the loss of one of your key and internally-natural antioxidants: glutathione. Glutathione is a powerful antioxidant produced by your own cells, and it neutralizes those free radicals/reactive oxygen species. It also works expertly with antioxidants vitamin C and E. And as your glutathione levels fall, a cascade of toxic deterioration and damage can also begin, from cells to tissues to organs. Scientists theorize, and studies propose, that this is what leads to conditions like:

Oxidative stress may also be negatively affecting your methylation process, such as the MTHFR enzyme.

Dr Andrew Weil explains :

Although we need oxygen to live, high concentrations of it are actually corrosive and toxic. We obtain energy by burning fuel with oxygen – that is, by combining digested food with oxygen from the air we breathe. This is a controlled metabolic process that, unfortunately, also generates dangerous byproducts. These include free radicals – electronically unstable atoms or molecules capable of stripping electrons from any other molecules they meet in an effort to achieve stability. In their wake they create even more unstable molecules that then attack their neighbors in domino-like chain reactions.

Some Causes of oxidative stress

There are quite a few situations mentioned in articles and studies which can cause your body to be overly stressed from the results of oxidation and all the reactive oxygen species. They include, but are not limited to:

  • excess endurance exercising
  • excess weight lifting
  • lack of key antioxidant nutrients like Vitamin C, Vitamin E, Selenium, Magnesium and other minerals
  • excess radiation or sunlight
  • smoking (huge cause of oxidative stress)
  • excessive drinking or drug use
  • over-exposure to toxins in our air, water and foods like pesticides, chemicals, heavy metals and more
  • prescription medications
  • processed foods with all their artificial dyes, additives or flavorings
  • excess physical trauma
  • Graves disease aka hyperthyroidism
  • excess copper levels from the MTHFR defect

Your thyroid condition and Oxidative Stress

In addition to all the above, there are a vast amount of documentation about the strong relationship between hypothyroidism and Oxidative Stress. In just four examples of many:

  1. Oxidative stress and enzymatic antioxidant status in patients with hypothyroidism before and after treatment :  concludes that “increased ROS levels in hypothyroidism may result in a pro-oxidation environment, which in turn could result in decreased antioxidant PON1 activity, increased MDA (malondialdehyde) and NO (nitric acid) levels”. ROS stands for Reactive oxygen species, which are chemically reactive molecules containing oxygen
  2. Serum Lipids and Oxidative Stress in Hypothyroidism : found relationship between high Total Cholesterol, Triglycerides, LDL and MDA levels in hypothyroid patients with oxidative stress
  3. Oxidative Stress and Antioxidant Status in Hypo- and Hyperthyroidism  “Despite some contradictory reports, the aforementioned results provide strong evidence that thyroid hormones induce oxidative stress in target tissues.”
  4. Oxidative stress status in hypothyroid patients.  “Hypothyroidism undeniably can be risk factor for in- creased oxidative stress; can eventually lead to many other complications. Antioxidant therapy and antioxidant diet should be advised along with thyroid hormone replacement therapy to diminish further complications.”

What we might conclude as informed thyroid patients

Plenty of research studies and articles underscore that lack of optimal thyroid hormones are strongly associated with your anti-oxidative status in a negative way, meaning the lack of adequate thyroid hormones means oxidative stress. And worldwide thyroid patient reports underscore the reality of a potential, hypothyroid-induced “oxidative stress profile” with their chronic inflammation and finding themselves more frequent illnesses, besides lowered levels of important nutrients (due to hypothyroid-induced low stomach acid) which can end up contributing to oxidative stress. In other words, all too many patients have reported continued hypothyroidism while being on T4-only, or they reporting seeing symptoms of hypothyroidism creep up the longer they stay on T4-only. Continued hypothyroidism can occur if you are undertreated even on Natural Desiccated Thyroid or T3-only thanks to being held hostage to the TSH lab test (or issues with untreated low cortisol).

Conversely, informed thyroid patients could surmise that proper treatment of their hypothyroid state, in addition to their acquire low iron, low nutrient, low cortisol state, could strongly improve their anti-oxidative status in a positive way. And reported patient experience in the use of Natural Desiccated Thyroid may be underscoring this, as well. Namely, patients who switch from T4 to NDT report far better health outcomes i.e. less sicknesses, better well-being, lowered inflammation.

In the meantime, the same four Italian researchers who did the study on T4-only, lung cancer and oxidative stress may eventually provide us with more tips to counter this issue.

Ten suggested strategies for informed thyroid patients to consider to counter oxidative stress

  1. Be on a thyroid treatment which gives the best results, and thus, may play a role in lowering your oxidative stress, which reported patient experience reveals to be natural desiccated thyroid (or adding T3 to your T4 treatment, or even being on T3-only).
  2. Get a wide variety of antioxidants in foods.
  3. Optimize and balance your blood sugar levels
  4. Identify and address your food intolerances
  5. Optimize your gut health
  6. Treat your low cortisol
  7. Dr. Kharrazian recommends the following nutrients: N-acetyl-cysteine (NAC), Alpha Lipoic Acid (ALA), L-Glutamine, Selenium, Cordyceps, Gotu kola and Milk thistle. (Learn about each before using)
  8. Consider meditation and/or Yoga or any other stress-busting activities
  9. Find ways to laugh…and laugh….and laugh!
  10. Get plenty of sleep.

Discuss all the above with your doctor so he or she can be included in your team approach to your health and well-being. Let’s STOP THE THYROID AND OXIDATIVE STRESS MADNESS! 🙂

New discovery about low magnesium & oxalates, plus a GOOD UK article, and when your spouse is hypo and wants out of the relationship!

(This page, originally written in 2011, has been updated to the present day and time. Enjoy!)

HAVE LOW MAGNESIUM LEVELS AND SYMPTOMS?

Do you have a hard time raising any of your mineral levels?

I have been working to raise my miserably low RBC (red blood cell) magnesium levels for a good year. And in spite of a strong commitment to my magnesium supplementation as well as oil, I continued to have typical low-magnesium symptoms–most especially lower leg cramping after hiking or heavy duty activity. Why was that?  I think I may have discovered one contributing factor, and this may or may not apply to you.  It’s called high OXALATE food consumption.

Oxalate is an “organic acidic salt compound” commonly found in foods of plant origin. It’s also produced in your body by the metabolism of glyoxylic acid or ascorbic acid (vitamin C).  And it is normally excreted out of your body via urine, and sometimes the bowels.

But it turns out if you consistently eat a LOT of food containing high levels of oxalates, on top of what your body naturally produces, your body might have excessive levels. This may be exactly what happened to me this year, also causing chronic hives (scratch~scratch~scratch). The latter pushed me to do research, and voila, I realized I had consumed far too many high-oxalate foods (which in turn produced excessive histamine). And my eyes popped out when I read this:

“oxalates strongly bind to minerals and vice versa (e.g., calcium, magnesium, zinc and potassium), and reduces the absorption of your minerals as they both come out via your urine.”

Of course, I am only proposing this may be why I’ve had a hard time bringing my magnesium levels up. Please do your own research.

What are foods which are the highest in oxalates?

In alphabetical order, they include:

almonds, amaranth, black beans, brazil nuts, beets, blackberries, buckwheat, carob chips, carrots, cashew nuts, cannellini beans, celery, chocolate, corn meal, dried apricots, cooked tomatoes, great northern beans, green peppers, hazelnuts, marshmallow root, milk thistle, navy beans, oil of oregano, okra, peanuts, pecans, pine nuts, pink beans, pinto beans, potato chips, potato flour, rice bran, rhubarb, sesame seeds and tahini, slippery elm bark, all soy, spinach, star fruit, sweet potatoes, teff (flour and whole grain), quinoa (whole grain), white bean flour, and yucca powder.

And what was I eating daily as I was working on the final updating of the revised STTM book this year? Cocoa-covered almonds! Almonds are considered a very-high-oxalate food, as is cocoa.  That was on top of the slivered almonds in my morning yogurt, as well as my consumption of pecans, spinach, and okra. I also drink iced tea daily, which can have higher levels of oxalates. And many times, I grabbed small amounts of frozen sugar-free carob chips every few hours. ~~blush~~

I am currently on a low oxalate diet (besides a great herbal blend four times a day to counter the itchiness and histamines).  And I am curious that by lowering oxalates, I just may finally be able to get my magnesium levels up and far faster.  We’ll see. To see a good blog post and list of oxalate foods (high and low), called Roo’s Clues, go here.

And for more to the oxalate story, including its connection to autism, leaky gut, depression, kidney stones, yeast overgrowth and arthritis, read this.  B6 is also crucial in lowering oxalates.

P.S. Here’s research that may underscore a relationship between oxalates and mineral loss.  The problem with research is that one study will say one thing and another will say the exact opposite! So you decide! If you know of more research on this topic, let me know and I’ll add it.

**************************

UK thyroid patients are clapping at the latest article which appeared in the July 3rd “The Mail”, a UK based, Sunday only magazine. It’s titled  “For Twelve Years I was a victim of The Great Thyroid Scandal” by Matthew Barbour. You can read its entirety here.

**************************

WHEN YOUR HYPOTHYROID SPOUSE OR LOVED ONE IS RUINING YOUR MARRIAGE or RELATIONSHIP:

Over the years, I’ve gotten several emails, and mostly from men, who are emotionally suffering.  But it’s not because they themselves are hypothyroid. It’s because their spouse/girlfriend is, and many of the latter seem to be in the throes of adrenal fatigue and low cortisol, as well.

The correspondents all seem to love their spouses dearly. But their spouses are defensive, over-reactive, paranoid, depressed and/or reclusive—all typical symptoms of having low cortisol. Depression is especially a problem even for those who just have undiagnosed or T4-only treated hypothyroidism.  And most all of those who email me are facing extremely unhappy relationships at the least, and pending divorces at the worst, even while still loving their spouses and wanting to stay married or connected.

The irony of the Oprah debacle for thyroid patients

opraharmsupI’ve been sitting back silently, reading all the backlash that started with Newsweek’s Best Life or Risky Advice May 30th article, a critical analysis of Oprah’s multiple program topics of Wish Away Cancer! Get A Lunchtime Face-Lift! Eradicate Autism! Turn Back The Clock! Thin Your Thighs! Cure Menopause! Harness Positive Energy! Erase Wrinkles! Banish Obesity! Live Your Best Life Ever!

And granted, some of the criticism seems justified.

Even thyroid patients winced and squirmed when Oprah stated that a month long Hawaiian vacation and eating fresh foods with soy milk were a great way to treat her thyroid condition.  Uh huh.   Patients equally gagged at her support of Dr. Christiane Northrup who made the the nutty insensitive comment that our thyroid problems were due to an “energy blockage in the throat region, the result of a lifetime of ‘swallowing’ words one is aching to say.”

But the ensuing array of blog posts and articles following in the footsteps of the Newsweek criticism of Oprah has presented quite an irony for thyroid patients whose lives have been changed thanks to natural desiccated thyroid. Adjectives and/or descriptions of Oprah in these blogs and articles have included:

* dangerous

* peddling alternative treatments that are ineffective

* failing to present scientific evidence

* failing to listen to bona fide, medical school trained,  medical professionals

* being too gullible about the so-called wisdom and knowledge of certain patients (ala Suzanne Somers)

* failing to give more attention to science-based, status quo, mainstream medicine

Any of the above sound familiar? Yup, it sure does.

How many times have thyroid patients been told that desiccated thyroid like Armour or Naturethroid was dangerous, or raising it by symptoms rather than the TSH was dangerous. Or it’s dangerous to use because you’ll get heart problems and osteroporosis. Yet thyroid patients on desiccated thyroid have their lives CHANGED, with stronger hearts and increased bone density.

How many patients have had their doctors tell them that desiccated was ineffective as an alternative out-dated product, yet these same patients started to LIVE again with relief from old symptoms from this ineffective “alternative” medication that grandma once used.

How many articles by medical professionals are there who claim that there’s no scientific evidence to prove that desiccated thyroid is effective, in spite of CLEAR observation and reports of a huge and growing body of thyroid patients and certain doctors around the world about relief from depression, lowered cholesterol, better blood pressure, weight maintenance, hair regrowth, better stamina, less sickness and a myriad of other improvements!

How many bona fide, medical school trained,  medical professionals told us ad nauseum that our symptoms were not thyroid related (when they were), that we are “normal” because the TSH lab test says so (when we were far from it), that desiccated thyroid is outdated, unreliable, ineffective, and a ten ton load of other ridiculous comments from bona fide, medical school trained,  medical professionals.

How many doctors have told patients that they should NOT listen to other patients on the internet or Stop the Thyroid Madness because patients can’t possibly have any wisdom or know what they are talking about. Yet, lo and behold, it’s been patients and what they have learned who have started a wide-reaching revolution for better thyroid treatment that works, and a growing body of doctors are listening!

And how many times has science-based, status quo, mainstream medicine completely ruined the lives of thyroid patients because many doctors are too lazy to dare question or think outside the pharmaceutical, medical school box.

Yup, Oprah has made some blunders, gaffes and misjudgments as outlined in the Newsweek article.  She has gushed too quickly when Northrup opens her mouth or Oz walks in with his surgical garb.  But isn’t it a bit ironic that some of the criticism by others towards Oprah are the same blunders, gaffes and misjudgments which most any thyroid patient has heard about their use of desiccated thyroid, and which has all been COMPLETELY wrong.

Bottom line, for every mistake and misjudgment Oprah has made–and CLEARLY she has done so in her understanding of thyroid treatment—she just might be opening the doors to medical truth, somewhere, somehow, between it all.
