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! 🙂

About Quinoa; Mistakes made on T3-only; Thyroid Patients and West Nile Virus

“WHAT IS THAT??”

As a thyroid patient who went to hell and back thanks to 20 years of a lousy treatment by allopathic medicine, I care about my good health and what I eat. So I attempt to balance my eating sins. And when I was recently at a salad bar, I couldn’t figure out what a particular bowl of food was, sitting next to mixtures of fruit, pastas, etc.

It looked like “frog eye salad”, which is made up of teeny tiny b-b size pasta and sweet fruits. But this had tomatoes in it. And the small round things had a thin white line around them. Were they fish eggs??

Turns out its a high protein, higher fiber whole grain called Quinoa (pronounced keen-wa), and is loaded with nutrients, including the minerals iron, zinc, and selenium, plus vitamin E and lysine, and all essential amino acids. I got a scoop and I was impressed.

And voila….if you need to be gluten-free, this grain gets the mark! I plan on buying some at my local health food store for an occasional hot breakfast cereal (as I suspect my husband would do better avoiding gluten thanks to frequent digestive issues), besides strongly recommend it to my husband’s niece, who badly needs to go gluten-free to lower her high inflammation levels.

Don’t feel the need to avoid gluten?? This still looks like a great grain and food to become familiar with, which I’m going to do! But a word of warning: it’s not low carb. So like any carb you intake, you’ll want to eat it in moderation.

KEY MISTAKES IF YOU ARE ON T3-ONLY, says a lot of patient experience

Though ten years of strong patient experiences show that natural desiccated thyroid gives the best results for thyroid disease, some thyroid patients have to be, or choose to be, on T3-only. It’s definitely a far better treatment than the lousy T4-only treatment with Synthroid and other brands.

And along the way, we’ve figured out some mistakes we may be making when using T3-only:

  1. Dosing rigidly every certain amount of hours  When patients were first learning about using T3-only (which requires more multi-dosing at first than does natural desiccated thyroid), we thought it was a good idea to dose rigidly about every 4-5 hours or so, thinking that T3 would peak about 4 hours after taking the first dose, then make a fall, and you’d then need to replenish your levels. We were wrong with that rigidity.It can be very individual when one needs a dose of T3. Some might need another dose of T3 in three hours after taking the first one due to a higher metabolism. So if they go longer, they put themselves in an increasing hypothyroid state. Another person might be a slow metabolizer and only need their next dose in 5 or 6 hours. So if you take it too soon, you put yourself in the direction of a hyper state.Turns out you need to be dosing  T3 when your body tells you it’s time you need it! How to know? Your signs and symptoms. Look for clues that you need your next dose, like a rising heartrate or blood pressure, depression, fatigue, or any hypothyroid symptom unique to you. Notate that on paper, then you’ll know to take your T3 right before that time the next day. It might take a few days of experimenting to figure out when your ideal dosing times are.
  2. Multi-dosing T3 too many times during the day As patients, we used to think that we need to dose T3 up to four to fives times a day in smaller doses. But with our new knowledge about T3, several patients have noted noted that moving dosing to 2-3 times a day, and thus in larger amounts each time, has resulted in better treatment of their hypothyroid state, especially with better cortisol levels.
  3. Thinking that different brands of T3 are equal  Unfortunately, some brands of T3 are weaker than others. And occasionally, some batches of a better brand may be bad due to heat exposure.  Generally, patients have reported Cytomel to be of a quality and consistent strength. Cynomel has been reported as equal in strength, but lately, patients have found some batches to be weak and are reporting this to the company. UK’s Liothyronine by Goldshield has been reported by patients as weaker in strength all the time.  All in all, Cytomel has received the most positive scores.

Using T3 all day while doing the T3 Circadian Method (T3CM) for your proven adrenal fatigue?? As your adrenals kick back in, you may notice that you 1) need to space your T3 farther apart, and 2) that you will need less T3.

WEST NILE VIRUS IS BACK LIKE A VENGEANCE: WHAT YOU AS A THYROID PATIENT SHOULD BE DOING!

Found out that a cousin of mine, who’s a father of two young children, found himself with West Nile Virus several days ago. I got West Nile about 5 years ago, as well. For many of us, it’s like the WORST flu you ever had, and you can take a few weeks to get over your post-illness weakness.

And since having a compromised immune system (as struggling hypothyroid/adrenal patients can have) makes one more vulnerable to the virus effects, I can see it being imperative to be on immune-supportive herbs right now, besides putting on some kind of mosquito repellant of your choice. I also read about Lomatium root, which is supposedly very anti-viral. I would talk to your local health food/supplement store for recommendations.
