Thyroid

The thyroid gland secretes the aptly named thyroid hormone. The over-production or under-production of this hormone can cause big problems in the body and lead to a myriad of symptoms that sometimes goes undiagnosed or misdiagnosed.
What does thyroid hormone do?
It regulates:
– heart rate
– metabolism & body temperature
– cholesterol levels
– weight
– vision
– menstrual regularity
As we age, and our glands, including the thyroid produce less hormone, we typically fall into a syndrome of hypothyroidism.
Some of the signs of hypothyroidism are:
– slow-down of metabolism
– loss of energy, excessive fatigue
– weight gain, even with extreme dieting
– memory and mood disorders
– cold sensitivity
– menstrual problems
– constipation
– generalized hair loss
– thinning nails
Because a patient with hypothyroidism is not producing enough thyroid, the pituitary gland, which monitors thyroid levels in the blood, starts secreting TSH (Thyroid Stimulating Hormone). TSH “cracks the whip,” forcing the thyroid to work harder. The strain and stress on the thyroid may cause enlargement of the thyroid—a “goiter.”
Diagnosis of hypothyroidism
Hypothyroidism is not easily diagnosed by physicians because the symptoms are that which are routinely attributed to old age, that is the loss of energy, weight gain, etc. A “Thyroid Panel,” measuring TSH, Free T3, and Free T4 levels should be part of a basic blood chemistry panel in everyone over 30 so this “old age issue,” may be treated.
Normal blood work and abnormal symptoms
Thyroid testing is broken up into the thyroid hormone components Free T3 and Free T4.
Briefly, the designations come from the number of iodine molecules connected to the thyroid hormone. In T3 (triiodothyronine), it’s three iodine molecules, in T4 (thyroxine), it’s four.
T3 is much more potent than T4 but considerably less abundant in our bodies. To counterbalance T3 and T4 levels, our bodies, especially the liver, collect T4 and convert it into the higher potency T3. If there is a problem in this conversion process, even though blood tests would be considered “normal,” the patient is considered “sub-clinically,” hypothyroid. There may be enough circulating Free T4 in the blood, it is just not being converted to T3. The indications from these blood tests will help differentiate which type of thyroid supplementation should be recommended in each individual’s case.
The ratio of T4 to T3 in the body is a little more than 9 to 1. When hypothyroidism is diagnosed, typically it is T4 (Levothyroxine) that is prescribed. Why? Because many doctors believe that the body will convert the T4 to T3 as it is needed. However, occasionally, T4 will convert to an excess of reverse T3 which is ineffective in up regulating metabolism, and little T3 is produced, leaving a patient hypothyroid in spite of high T4 levels and low TSH levels. It is very important that the patient is closely monitored to indeed make sure that this is not happening. Some physicians also prescribe Armour thyroid, which is a combination of T3 and T4, or a compounded version can be made. Some doctors do not like to prescribe Armour because the T3-T4 ratio is not exactly standardized. Again close monitoring by a physician can gauge if the desired result is being achieved.
Questions About Thyroid Supplementation
When To Take Your Thyroid Supplementation?
Take your medication before breakfast on an empty stomach.
Many physicians believe that you can best absorb your thyroid medication by taking it on an empty stomach.
Additionally, some foods or supplements (those contain calcium and iron) may prevent proper absorption.
Remember that it is important to check thyroid levels regularly to regulate dosage and absorption. If there is an absorption problem or your dose needs to be adjusted, regular blood tests will bear this out.
How Do You Know You Are Reaching Your “Best” Thyroid Levels?
Thyroid supplementation for low or hypothyroid conditions should start effecting the following:
– An increase in metabolism
– An increase in energy
– Increase in your ability to lose weight
– Improvements in memory and mood
– Better digestion and regular bowel movements
– Hair loss BECAUSE of HYPOTHYROIDISM is reversed
– Improved condition of skin and nails
If you are on thyroid medication and are not seeing a more positive improvement than you or your doctor anticipated, regular blood tests should be performed to check thyroid levels and adjustments in medication or in dietary habits maybe needed.
Hypothyroidism and Low Testosterone Levels
Recent research published in the International Journal of Andrology says that there is a direct association between subclinical hypothyroidism and a reduction in testosterone levels in men and further, “Testosterone deficiency and its symptoms should be kept in view while managing subclinical hypothyroidism in male patients.”
Hypothyroidism is not easily diagnosed by physicians because the symptoms are that which are routinely attributed to old age, that is the loss of energy, weight gain, etc. A “Thyroid Panel,” measuring TSH, Free T3, and Free T4 levels should be part of a basic blood chemistry panel in everyone over 30 so this “old age issue,” may be treated.

Hormone Supplementation
What are hormones?
What is hormone supplementation?
How does it enhance vitality even as we age?
Hormones are chemicals within our bodies responsible for many things including the regulation of our metabolism, immune function, blood pressure, sugar levels, body temperature as well as a host of other things including regrowth and repair of damaged tissue. They are produced by our glands, namely the Thyroid (Thyroid), Adrenals (DHEA, Pregnenolone), Pituitary (Human Growth Hormone (HGH)), Ovaries (Estrogen, Progesterone, Testosterone) or Testes (Testosterone), and Pineal (Melatonin). After about the age of 30, our body’s hormone levels start to decline. Many cite this decline with the “normal” aspect of aging and its familiar characteristics of fatigue and loss of energy, problems of memory and mood, lack of ambition, loss of libido, weight gain and muscle loss and much more that add up to a sense of poor health. This hormonal decline continues as we age, and usually becomes problematic in our 40’s and 50’s, although, it can create issues at an even younger age. An example are the statin drugs that can cause a dramatic decrease in testosterone even at a young age. With testosterone decline, we find incidence of erectile dysfunction.
Giving “pause” to thought We have all heard of and embraced the term menopause to describe a decline in the female sex hormones, but there are other “pauses” that are becoming more recognizable as house-hold names. Doctors have coined the terms “andro-pause” to describe the decline of male sex hormones in men, “somatopause” to describe the decrease in human growth hormone, “adrenalpause” to describe a decline in DHEA, and “pinealpause” to describe a decline in melatonin.
In the opinion of many doctors, maintaining optimal hormonal balance is our best opportunity to enhance vitality into “old age” and overcome these “pauses” in life. Some doctors however believe that aging is inevitable and that nothing can be done about it except to accept it gracefully. This is a stigma of modern medicine. On one hand, medicine is proud, and rightfully so, of enormous jumps in life expectancy ages, but on the other hand, they are skeptical about enhancements in quality of life. Therefore some doctors may be reluctant to treat hormonally deficient patients because they see this as a normal result of aging, and something they can’t do anything about.
In other words a 70 year-old man presents himself to the doctor’s office with complaints of loss of sex drive, fatigue, and inability to lose weight. It is likely that his doctor will say, “You are 70 years old, and this is normal for your age!”, rather than take blood tests of hormone levels. If the patient was insistent about getting his hormones checked the doctor may see “normal” results, that are the normal ranges for a man 70 years old and tell the patient that he is normal. But the patient isn’t “normal,” that is why he went to his doctor! He doesn’t want the hormones of a 70 year-old man, he wants the hormones necessary to have sex drive, muscle tone, strength, ambition, joy, and his vitality back. He also wants a good chance to be free of heart disease, diabetes mellitis, and other diseases of aging. Why not check his c-reactive protein, fasting insulin, and homocysteine levels, along with many other markers of hidden disease?
