Tricky Thyroid Tests: Is there something wrong with my thyroid in spite of “normal” tests?

Overview of the thyroid system (See Wikipedia:...

Suffering from fatigue, constipation, weight gain, depression, brain fog, cold intolerance, hair loss, irregular menstrual periods, low libido and perhaps a host of other unexplained symptoms? Had tests for thyroid and results come back normal? Could it be that the “thyroid tests” only consisted of TSH (a pituitary hormone) and T4? Let’s say that “all” the thyroid tests were done and everything came back “normal”, is it still possible to have some underlying thyroid issues? Have you been tested for free T3, thyroid antibodies or reverse T3? Is there a family history of thyroid problems? Any history of sub-normal body temperatures (average body temperature less than 98.6)? Are you “freezing” all the time? Do you ever get a fever when you’re fighting off an infection? If any of the above questions got you thinking “could I possibly have thyroid issues?”, then you may be right. It’s always helpful to listen to your body (or intuition) coz in this society, we are brainwashed to think that medical authorities know our body more than we know it ourselves (although in certain instances, we need “expert’s”  opinions).

Back to making a diagnosis of thyroid issues. Free T3 is the metabolically active form of thyroid hormone. If it’s “low normal” and if a person has concomitant low thyroid symptoms, then it will be helpful to support the thyroid. In a holistic practice, one may start with nutritional support of the thyroid and if that doesn’t work, a trial of actual thyroid hormone could be used. The use of animal glandulars with both T3 and T4 such as Armour thyroid is preferable since some people who use synthetic T4 alone may not be able to convert it to T3 due to nutritional deficiencies including that of the mineral selenium. By the way, it’s also important to address adrenal dysfunction if a person has thyroid issues in the first place. In Chinese medicine, these are considered yin yang organs and are supposed to support each other. Substances that help the adrenals are called adaptogens and include rhodiola, ashwaghanda, ginseng, cordyceps and holy basil. Nutrients such as vitamin C and pantothenic acid also support adrenal function.

Anyway, for those with auto-immune type of thyroid conditions, it would be helpful to test for food sensitivity as well. Sometimes, getting off offending foods could resolve the thyroid issue. Interesting, huh?

Why is it that we’re seeing a lot of thyroid problems nowadays? The thyroid is one of the most vascular organs in the body. Toxins that we’re exposed to on a daily basis usually affect our thyroid. Some of these toxins are so ubiquitous in the environment that it’s sometimes difficult to avoid them. Some could be avoided entirely though (such as water that’s been purified with halides such as chlorine, bromine or fluoride). They all compete with iodine in the formation of thyroid hormone. Stress also affects thyroid function (elevated cortisol preventing the conversion of T4 to T3). Nutritional deficiencies also plays a major factor in the prevalence of thyroid disorders nowadays.

Mad as a Hatter: Does It Matter?

Alice in Wonderland iPhone wallpaper

If you think I’m talking about the character in Alice in Wonderland, think again. In today’s blog, I’m going to discuss how toxins, particularly heavy metals (like mercury) could affect everything, including our mental health. The phrase “mad as a hatter” was coined in the early 19th century when “hatters” or people who were making hats started experiencing uncontrollable trembling and appeared insane. Apparently, the hatters were using glue that contained mercury at the time. Mercury toxicity can manifest as loss of appetite, fatigue, depression, emotional instability, peripheral numbness, tremors, poor memory and cognitive function, decreased senses of touch, taste, hearing and vision, and neuromuscular disorders. High levels have also been implicated in acute myocardial infarction. All the symptoms just mentioned  are quite common. Therefore, it’s always a great idea to rule out the presence of (heavy metal) toxins in anyone experiencing the said symptoms or anyone who has a possible exposure to mercury (and that means all of us). Mercury is now found all over the place, including our air (esp. surrounding coal-powered plants), food and water supply. In fact, common sources include fish (all fish now, compared to just large fish during previous years), dental amalgams, skin lightening agents (very common in Asia), some hemorrhoidal creams, some vaccines, medical instruments such as thermometers and sphygmomanometers, batteries, electrodes, some fertilizers, the paper industry and finally, the gold industry. In fact, there were recent reports in the news of mercury/lead toxicity in parts of Nigeria where people are involved in gold mining.

To test if someone has elevated levels of metals, particularly mercury, one can have a blood, hair or (provocative) urine testing done with chelating agents like DMSA or DMPS ( although others may use EDTA or other natural chelating agents). A blood specimen is usually used to determine acute exposure while hair and urinary testing informs us more of chronic exposure. Labs that perform the latter tests include Doctor’s Data and Genova Diagnostics. In Asia, I would imagine that Vitech Pro, a company based in Bangkok, is the one that performs these tests. Regular blood tests for mercury could be performed at any reputable lab like Quest or LabCorp. What do you do if your levels are elevated? Besides avoidance of possible sources (kinda difficult nowadays), the accepted form of treatment is a process called chelation therapy.  This has to be done properly however. Otherwise, further damage can be done. Natural oral chelating agents include vitamin C, alpha lipoic acid, garlic, cilantro, onions, chlorella and some therapeutic-grade essential oils. EDTA is available in oral (least effective), suppository and injectable forms. Other chelating agents include penicillamine (for copper toxocity), deferoxamine (for iron poisoning), dimercaprol (for arsenic, mercury and lead), DMSA and DMPS. It is important to individualize treatment in any case. Factors such as kidney and liver function, nutritional deficiencies, allergies, and general patient constitution should all be taken into account when one embarks on a cleansing or detoxification program.

The Good Bugs: Why You Absolutely Need Them

Lactobacillus acidophilus

Probiotics, we hear all about them now. TV, radio and print ads! It’s great, considering that just a few years ago, most people didn’t know what they were. Probiotics, otherwise known as “good germs”, are part of the normal flora of our intestinal tract. They begin to inhabit our intestinal tract as soon as we’re born (by vaginal delivery, rather than caesarian delivery). They are nourished by eating healthy foods from infancy, starting by drinking mother’s milk (rather than cow’s milk or soy milk). As we age and are exposed to poor diet, antibiotics, chlorinated water, steroids and environmental pollutants (xenoestrogens), their numbers begin to decline. When their numbers decline, pathogenic yeast begin to overgrow (as well as bacteria), causing symptoms in both men and (more obviously in) women (such as vaginal discharge). Known functions of probiotics include: 1. the manufacture of B vitamins (such as folic acid, biotin, B3 and B6); 2. the manufacture of the enzyme “lactase”; 3. produce antibacterial substances; 4. produce anti-carcinogenic compounds; 5. help reduce high cholesterol levels; 6. improve the efficiency of the digestive tract; 7. help recycle hormones such as estrogen; 8. protect against radiation;  and 9. deactivate certain toxins, among many others. The primary bacteria inhabiting the small intestine is Lactobacillus acidophilus while that of the colon is Bifidobacterium bifidum. It is essential that these organisms be replaced when taking antibiotics of any kind. In today’s world, it’s a good idea to incorporate probiotics in a wellness program because of the antibiotics that we’re unknowingly exposed to (from food and perhaps, our water supply). There are different brands available. Some need to refrigerated while others do not. They come in various forms such as powders, liquid, capsules or “pearls”. To find out which brands are better, check out a study done by Consumer Labs. In the study, they found out that claims made by some companies such as number of viable organisms in their product somehow vary from the actual live cells. Factors such as improper storage and handling as well as shelf life affect these numbers. Therefore, it’s always important to do your own research.

Back to Basics 1

Wow! It’s been a while since I last wrote a blog entry. It’s been a busy new year for me. Hopefully, I’ll be writing on a more consistent basis. That, is my new year’s resolution. Hey, it’s better late than never, right?

Anyway, I’m back after spending a few days with a couple of Lyme -literate doctors here in the Bay area. It’s great to see how various practitioners approach the Lyme disease epidemic in different ways (some more “holistic”, while others more “conventional”). I would say that they’re both highly effective, considering how their clients consistently come back for follow up (coz they keep getting better). It’s sad however, how insurance companies sometimes dictate what they’ll cover or not. After all, it’s the doctor who actually treats the patients. Overall, they’re good at collecting your insurance premiums. But when it comes to actually covering for services, they suck (pardon my “French”; no offense to the French, however). Like one of the doctors who I shadowed said, they (insurance companies) are in the business of making and saving money, first and foremost. If they do really want to save money, they should be looking into more preventive health care (or going back to basics). Incorporating nutrition, fitness and stress reduction, could go a long way in solving the health care problems in our country. One good thing though, some of these companies are starting to “see the light” by incorporating stress reduction programs.

More on what I learned during my preceptorship with LLMD’s in the next few days……

New Year’s Resolutions

Here we go again making new year’s resolutions. Among the
most common resolutions include losing weight, stopping unhealthy
habits such as smoking or drinking, and starting an exercise
program. Whatever a person’s new year’s resolution is, it is
important to be patient and give ourselves a break when things
don’t go as planned. Anyway, I’d like to discuss the issue of
addictions, whether it’s smoking, drinking, gambling, you name it.
Oftentimes, these addictions are brought about by nutritional
imbalances. To put it simply, people oftentimes crave certain
things because they lack nutrients such as vitamins, minerals,
amino acids, essential fatty acids, and trace elements.
Fortunately, there are tests available that could tell us exactly
what we’re lacking. These tests could be done through the blood,
hair, and the urine. Of course, these tests are not mainstream yet,
so your conventionally-trained doctor may not be aware of these
tests. However, a simple CBC and serum chemistry can tell us what’s
going on with a person nutritionally, although indirectly. A CBC
for instance, can tell if there’s iron, B12 or folic acid
deficiency. High blood sugar could be due to lack of vitamin B1 or
thiamine. Low creatinine could be due to protein insufficiency or
impaired digestion. Low uric acid could be due to copper or
molybdenum deficiencies. Low CO2 can also be due to a lack of
vitamin B1 or thiamine deficiency. Low albumin could be due to a
need for more vitamin C. Low AST/SGOT and low ALT/SGPT could be due
to vitamin B6 deficiency. Low GGTP could be due to B6 or Magnesium
deficiency. High total/free T-3 could be due to iodine deficiency
while low total /free T-3 could be due to selenium deficiency. Low
total/free T-4 could be due to iodine deficiency. In summary,
“normal” tests don’t really mean anything because it’s mostly based
on statistics. Low normal or high normal mean something, especially
if a person is symptomatic. It goes back to individualizing
treatment or a more personalized medicine.
