Eric, Metabolism.com member, explains why T4 only doesn’t work


A long time member of metabolism.com, Eric Pritchard, has been a determined critic of “T4 only” treatment of hypothyroidism.  In his latest comment Eric shows that scientists were aware of the inadequacy of “T4 only” treatment since 1947!  I wanted to give everyone a chance to read his comment so I am posting to the main blog. Thanks again for your insight Eric.

Eric writes:

Endocrinologists have a hard time with the symptoms of hypothyroidism in the same sort of way that New York City folks believing that there is anything worthwhile west of the Hudson River. However, there are very relevant functions to the thyroid hormone effectiveness that exist beyond the boundaries of the classical endocrine system. This potential was given initial credence by Drs. Kirk and Kvroning in 1947 when they published a note saying that not all patients’ symptoms were managed by thyroxine (T4). This was collaborated in 1954 by Dr. Means. Drs. Gross and Pitt-Rivers discovered triiodothyronine (T3) and found it far more active than T4, which is now called a pro-hormone. The concept of euthyroid (your thyroid is OK) hypometabolism (but you are dragging anyway) was demonstrated by Dr. Goldberg in 1960. Drs. Refetoff and Braverman, circa 1970, discovered the connections between the thyroid gland and symptom producing cells, namely the cellular reception of hormones and the conversion of T4 to T3 outside of the endocrine system, which produces 80% of the body’s requirement for the active hormone, T3.

Another issue that is dismissed is the necessity of supporting chemistry to function properly. For example, every thyroid hormone replacement counter-indicates is use if the adrenals are insufficient.

So there is far more going on than endocrinology is willing to promote. That is why there are 1.7 million patients suffering in spite of T4 therapy. That is why there are still more patients suffering from false negative diagnoses for the symptoms of hypothyroidism.

SweetiePie Doesn’t Need a Shrink to Quit Smoking


Many members here at metabolism.com have shared their thoughts and experience on ways to stop smoking. There have been many who feel defeated because they can’t beat the weight gain that accompanies their efforts. SweetiePie has a clear message about how not to beat yourself up while achieving the goal of a smoke free (and healthier) life.

Here’s what SweetiePie has to say;

Hello:

55 Year old female here, 200 lbs, hypothyroid smoke free for 6 months. Feeling great about being smoke free and this time its permanent and for real.

I have quit smoking and relapsed so many times in my life. And dieting, on again and off again for 40 years. Pfffft…..This time what prompted me to go to the doctor and quit was that my heart feels heavy and hurts sometimes. Not angina yet, but scary and depressing. I’m fine, it turns out, but I definitely needed to quit smoking and still need to exercise more and lose weight . I am no expert in the weight loss department, having had limited success with that over the years. I can see from this interesting thread that I am not as weight conscious as most of you, but I still thought I’d share what my doctors told me because it may help and inspire you the way it did to me: When I tried to bring up the weight gain and the overweight with doctors heres what they said: CARDIOLOGIST told me I’d have to be about 100 lbs over my ideal weight of 145 for the weight to be as stressful and damaging on my heart and cardiovascular as SMOKING, GP #1 told me the key was, instead of focusing on an ideal weight and size, was to focus on preventing DIABETES through NONSMOKING, AND EXERCISE just as important as wholesome diet, and GP #2 (I moved and needed a new doctor for my thyroid perscription) told me, after my bloodwork tested all ok, “why don’t you just forget about losing weight for a little while and focus on quitting SMOKING? Well, I took all of that advice, and this time, it worked! I’ve really kicked the smoking habit and finally found freedom from that deadly addiction. The “permission” from doctors to stop beating myself up about my weight freed me up mentally to do what I needed to do (giving myself plenty of rewards, including food treats and being lazy treats!) in order to become smoke free and never going back! I am ready now to step up to exercise and weight loss this year with the same strategy: Increased exercise first, food modification instead of deprivation. The reason for my post is to say stick with it but your QUIT is SO IMPORTANT – don’t ever let your desire to be thinner or to get back down to an ideal outweigh your resolve to stay SMOKE FREE. SMOKING is the singlemost damaging behavior -don’t lose sight of that! Never take another puff! Oh, btw I gained about 5% while quitting and my first goal is to go back down 5%.

Patti Keeps on Running Despite Thyroid Cancer


Thyroid cancer is one of the most common cancers of young adults. Many of these cancers have no symptoms until a routine exam reveals a lump in the neck. This was the case with Patti who shares her upbeat experience with us. The good news about this type of cancer is that despite spread to lymph nodes (metastasized) it is still very curable. So, if you notice an unexplained neck lump don’t hesitate to have it evaluated by an endocrinologist or other knowledgeable physician.

Here is what Patti has to say about her thyroid cancer experience;

I found a lump in my throat in August of this year. I am one of the few (about 10%) who tested positive for Thyroid cancer. I also had cancer in 4 of the lymph nodes of my neck. I am a competitive athlete (for fun not for a living) and I worried what would happen. I had surgery in September and although the last 4 months have been very hard on me, I am happy to report I am running, swimming and cycling again. The cancer is completely gone based on my body scan and negative bloodwork.

Most likely you do NOT have cancer. But you can’t roll the dice and not know. And if you do, you can and will get through it and go on to live a wonderful life. It takes work and perseverance to be healthy but it is worth it. 🙂

HCG is a Hairy Hormone



By Gary Pepper, M.D.
Editor, Metabolism.com
In the first article in this series, The HCG-Cancer Connection, I explained how HCG is made by some types of cancer and can serve as a marker for cancer activity. Now I want to explore another effect of HCG, the stimulation of male hormone (testosterone) production.
Just to review, there is no evidence that HCG will cause cancer although conceivably certain cancer responsive tumors may grow faster due to its effect to increase estrogen and testosterone. Every woman who has had a normal pregnancy has been exposed to high HCG levels for many months so if it did cause cancer that effect would be very obvious.
What concerns me is how HCG can influence the normal ovary and its hormone metabolism. HCG is a promiscuous hormone. It will hook up with different hormone “receptors” and masquerade as these other hormones. In the previous article I explained how at very high levels HCG can stimulate the thyroid to make thyroid hormone resulting in hyperthyroidism. Another hormone effect of HCG is to mimic LH (leutinizing hormone) which turns on the production of the sex hormones by the testicle in men and ovary in woman. Surprisingly the normal ovary makes testosterone which it then converts to estrogen. FSH (follicle stimulating hormone) from the pituitary helps the ovary change testosterone to estrogen. What happens when the ovary gets a lot of LH but not FSH? This is the situation when a woman gets HCG. Testosterone levels will rise more than estrogen levels. Research shows that after a single HCG injection a rise of 20% in testosterone levels occurs in normal women, confirming this theory. During pregnancy with HCG pumping in the blood from the placenta, testosterone levels can double, resulting in acne, oily skin and (in some women) an increase in sex drive. The situation would be far worse for a pregnant woman if the placenta wasn’t also pumping out 100 times the normal amount of estrogen to counteract all the male hormones.
So why should women care if HCG makes their testosterone levels go up? Acne, oily skin and horniness are one thing but there are other effects which might be less acceptable. Testosterone is a mischievous hormone. While it causes hair growth where you don’t want it, it causes hair loss in places you want to keep it. Testosterone stimulates hair growth on the face, chest, back and abdomen. At the same time it causes hair loss from the scalp particularly at the temples and crown. This is referred to as male pattern baldness. Other effects of testosterone in women are the growth of the clitoris, known as clitoromegaly. A clitoris the size of a man’s thumb has been described in a woman due to excess testosterone exposure. Generally this degree of clitoromegaly is seen only in more extreme cases. So you may want to think twice before starting an HCG diet unless looking like Bruce Willis is your thing.
In the final installment on the hazards of HCG I will focus on other possible nasty hormone effects of HCG such as fibroids, infertility and bulging muscles.

Lovey Needs Encouragement to Deal with Her Condition


Sad LadyLovey posts this sad message to metabolism.com. Many of the members here have been through this type of paralyzing doubt and have found a way to get the help they need. So, if you have a minute to spare, in the spirit of the season, why not offer Lovey a message that will help her get her nerve up to go to the doctor.

Lovey writes:

Hi, I’m too scared to go to the doc as I have a large lump in my throat. I don’t know much about thyroids or how it works an wat the worse case situations r. Alls I know is that the lump is about as round n size of a golf ball maybe abit smaller. I’ve had this lump for about 4 years an it’s recently started to get bigger. Ive gain about 12kg in about 8 months but I still do everything the same. I weigh 75 kg an MT height is 174cm. Something is wrong isn’t it!!!

Here is my reply to her;

Hi Lovey

A sluggish thyroid often produces a “lump” in the neck (which is the enlarged thyroid) and weight gain due to a slow metabolism. I’m not sure if you believe me but there really isn’t anything to be scared about. For example, if it turns out your thyroid is under active (low functioning or hypothyroid) the treatment is very simple. For most people taking one pill per day is all that is required to get back to normal. May people with hypothyroid are taking their thyroid pill and feel fine.

It’s hard to say exactly what the problem is in your case, but I wouldn’t be surprised if it is something like hypothyroidism, which could be fixed so easily.

So please get yourself to a doctor, clinic or whatever and have them look into this. Then you can stop worrying so much.

Okay? Let us know what happens. I’m asking other members here to give you their words of support as well, since many of the members here have gone through what you are experiencing and are happy they received proper treatment.

HCG, Your Hormone Metabolism and Cancer


by Gary Pepper, M.D.
Editor, Metabolism.com

Last week Helen, a friend of the family, called to brag she had lost 12 pounds in 4 weeks and also to ask if she had given herself cancer in the process. What was the connection between her supposed miracle metabolism and cancer? Helen was taking HCG injections and just read this hormone was somehow related to cancer. I reassured her that I didn’t think she was giving herself cancer by taking HCG but I did let her know that very soon she was likely to resume her normal metabolism and regain the weight she lost. Unfortunately her wallet was never going to recover what it lost in this process. Many services prescribing HCG treatment for weight loss are charging $400 or more for a course of treatment.

Now what about the cancer-HCG connection?

HCG is a hormone normally produced by the fertilized egg in the earliest stages of fetal development and then later by the placenta itself. Since rising HCG level is one of the earliest hormone changes during pregnancy, measuring this hormone is the basis for the everyday pregnancy test. HCG also causes the ovary to make progesterone which is essential for preparing the uterus to become a nesting ground for the developing embryo. HCG may also suppress immune function so that the fetus is not rejected by the mother’s immune system.

The placenta forms at the onset of pregnancy to support the developing embryo and later the fetus. If a sperm fertilizes an empty egg at the onset of pregnancy a Hyditidiform mole can arise in conjunction with or instead of the normal placenta. This is also referred to as a molar pregnancy. HCG levels can rise to extreme levels in the presence of the Hyditidiform mole particularly if it goes on to become an invasive cancer known as a choriocarcinoma. Body chemistry gets a little weird at this stage. HCG is slightly similar in structure to TSH, the pituitary hormone that stimulates the thyroid. The result is that when HCG levels are extremely high as with a molar pregnancy, the thyroid can be stimulated to make excess thyroid hormone resulting in hyperthyroidism in the mother. Typical symptoms of hyperthyroidism can occur including feeling hot, shaky, sweatiness, palpitations, vomiting (which can be severe) and diarrhea. Curing the cancer will cure the hyperthyroidism as well.

Other cancers of the reproductive system can make HCG as well. Certain testicular cancers can make HCG. Since HCG is the hormone responsible for a positive pregnancy test, testicular cancer can sometimes be diagnosed in men by a positive pregnancy test. For tumors making HCG, measuring levels of this hormone during cancer treatment can aid doctors in determining whether therapy is working or not.
Certain cancers are termed “hormone responsive”. That means the cancer will grow more aggressively in the presence of a particular hormone. Tumors that grow faster in the presence of estrogen include receptor positive breast cancer and endometrial cancer. A tumor that grows faster in the presence of testosterone is prostate cancer. Since HCG is likely to increase these hormones, it is conceivable that should a hormone responsive tumor already exist in the body it could grow faster during HCG treatment.

So Helen, I don’t think HCG is going to give you cancer, but it may cause you to grow a beard. Why is that? I’ll be explaining my theory in the next article, “HCG is a Hairy Hormone”. Visit metabolism.com for more on this, in the very near future.

Will T-3 Help Dana with her weight, hair, skin and mood?


Although we often speak of the metabolic effects of thyroid hormone, we are really referring to the fact that this hormone helps to regulate the function of every system in the body. A system that is often a source of concern is known as the integument; the hair, skin and nails. The effects of disease is often first noticed due to effects on the integument and thyroid disease is one of the most likely to show up here. Brittle hair that sheds easily, and skin that is dry, itchy and flaky are often noticed early in hypothyroidism. Here is Dana’s story and I’m hoping that the addition of T3 will help her lose her excess weight and also reverse the deterioration she is experiencing in her integument, and her nervous system (mood).

Dana writes:

I was diagnosed as hypo a few years ago and my doctor just added 25 mcg of liothyronine (Cytomel) along with 100 mcg of Synthroid. In the past year I have gained 35+ pounds and it’s been alomost impossible to take it off. Last year I competed in my very first fitness/ figure competion. At 135lbs I came in 2nd place. I play softball and basketball on competitve level teams for the psat 15 years and I run about 3-4 times a week. I eat relatively healthy and have recent gone gluten-free, soy free, and nitrate free. Today is my very first day on the combined T3/T4 thereapy. I steppeed on my scale and it said 174lbs. Im hopeful that not only my weight will decrease but my hair will stopp shedding, dry skin/ scalp, joint pain, hopelessness and depression, and fatigue will all go away. I know patience is the key so I will be patient and wait.

My response:

Hi Dana

As you read here, some people are unable to return to normal thyroid equilibrium on t4-treatment alone; this may be due to an inherited form of enzyme defect preventing the normal conversion of the t4 hormone into the more potent t3 hormone; I am happy you found a doctor who will prescribe T3. Sometimes this needs to be given twice daily since t3 is a short acting hormone and the benefit may wear off within 6 to 8 hours. Some people don’t notice this while others definately do.
Good luck with your treatment. Also remember, thyroid hormone allows you to lose weight normally but doesn’t make weight “melt off”. You still have to do the right things with diet and exercise but at least your efforts should start paying off.
Good luck.

Zach’s Treatment Success with Cytomel


Zach points out that most of the posts about thyroid treatment issues at metabolism.com are from women. That makes sense because autoimmune thyroid disease is approximately 10 times more common in women than men. But man or woman, thyroid hormone treatment is still the same and his success with Cytomel is something worth noting.

Zach writes:

Hi everyone. From what I can gather, most posters here are women, well I’m a guy with similar problems. I thought my story might be useful so that men don’t think it’s a women only problem. I gained a hypothyroid diagnosis at the age of 25 due to Hashimodo’s. There was no direct cause, it runs heavily in my family. For a year, or two, maybe even three (it’s hard to tell due to widespread symptoms), I was feeling nervous, bad memory, attention problems, sleep problems, low appetite, and easily fatigued from a normal 8 hour work day. I assumed my lifestyle choices were causing these symptoms so didn’t go to the doctor for years.

Finally when I was diagnosed I was put on levothyroxine. The very first day I took it I felt IMMENSLY better. However, months down the road the symptoms gradually built up again. Every time my dose was raised, I would feel better for about 2 days, but the symptoms would gradually return. My endo decided to drop my T4 dosage and put me on a combo T4/T3 (T4 was dropped by 50 mcg and one quarter of the drop was added in as T3, so 12.5 mcg of T3). This is the first day I’ve tried it, and instantly the morning of starting on T4/T3 my body aches have almost disappeared and I am feeling much less sleepy at my desk during work.
