Hypothyroidism

What is hypothyroidism?

Hypothyroidism refers to any state in which thyroid hormone production is below normal. There are many disorders that result in hypothyroidism. These disorders may directly or indirectly involve the thyroid gland. Because thyroid hormone affects growth, development, and many cellular processes, inadequate thyroid hormone has widespread consequences for the body.

What are thyroid hormones?

Thyroid hormones are produced by the thyroid gland. This gland is located in the lower part of the neck, below the Adam's apple. The gland wraps around the windpipe (trachea) and has a shape that is similar to a butterfly - formed by two wings (lobes) and attached by a middle part (isthmus).

The thyroid gland uses iodine (mostly available from the diet in foods such as seafood, bread, and salt) to produce thyroid hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3), which account for 99.9% and 0.1% of thyroid hormones present in the blood respectively. However, the hormone with the most biological activity is T3. Once released from the thyroid gland into the blood, a large amount of T4 is converted into T3 - the active hormone that affects the metabolism of cells.

Thyroid hormone regulation

The thyroid itself is regulated by another gland that is located in the brain, called the pituitary. In turn, the pituitary is regulated in part by the thyroid (via a "feedback" effect of thyroid hormone on the pituitary gland) and by another gland called the hypothalamus.

The hypothalamus releases a hormone called thyrotropin releasing hormone (TRH), which sends a signal to the pituitary to release thyroid stimulating hormone (TSH). In turn, TSH sends a signal to the thyroid to release thyroid hormones. If a disruption occurs at any of these levels, a defect in thyroid hormone production may result in a deficiency of thyroid hormone (hypothyroidism).

The rate of thyroid hormone production is controlled by the pituitary gland. If there is an insufficient amount of thyroid hormone circulating in the body to allow for normal functioning, the release of TSH is increased by the pituitary gland in an attempt to stimulate more thyroid hormone production. In contrast, when there is an excessive amount of circulating thyroid hormone, TSH levels fall as the pituitary attempts to decrease the production of thyroid hormone. In persons with hypothyroidism, there is a continuously decreased level of circulating thyroid hormones.

What causes hypothyroidism?

Hypothyroidism is a very common condition. It is estimated that 3 to 5% of the population has some form of hypothyroidism. The condition is more common in women than in men, and its incidence increases with age.

Below is a list of some of the common causes of hypothyroidism in adults followed by a discussion of these conditions.

Hashimoto's Thyroiditis
Lymphocytic Thyroiditis After Hyperthyroidism
Thyroid Destruction (from radioactive iodine or surgery)
Pituitary or Hypothalamic Disease
Medications
Severe Iodine Deficiency

Hashimoto's Thyroiditis: The most common cause of hypothyroidism in the United States is an inherited condition called Hashimoto's thyroiditis. This condition is named after Dr. Hakaru Hashimoto who first described it in 1912. In this condition, the thyroid gland is usually enlarged (goiter) and has a decreased ability to make thyroid hormones. Hashimoto's is an autoimmune disease in which the body's immune system inappropriately attacks the thyroid tissue. In part, this condition is believed to have a genetic basis. This means that the tendency toward developing Hashimoto's thyroiditis can run in families. Hashimoto's is 5 to 10 times more common in women than in men. Blood samples drawn from patients with this disease reveal an increased number of antibodies to the enzyme, thyroid peroxidase (anti-TPO antibodies). Since the basis for autoimmune diseases may have a common origin, it is not unusual to find that a patient with Hashimoto's thyroiditis has one or more other autoimmune diseases such as diabetes or pernicious anemia ( B12 deficiency). Hashimoto's can be identified by detecting anti-TPO antibodies in the blood and by performing a thyroid scan.

Lymphocytic Thyroiditis following hyperthyroidism: Thyroiditis refers to inflammation of the thyroid gland. When the inflammation is caused by a particular type of white blood cell known as a lymphocyte, the condition is referred to as lymphocytic thyroiditis. This condition is particularly common after pregnancy and can actually affect up to 8% of women after they deliver. In these cases, there is usually a hyperthyroid phase (in which excessive amounts of thyroid hormone leak out of the inflamed gland), which is followed by a hypothyroid phase that can last for up to 6 months. The majority of affected women eventually return to a state of normal thyroid function, although there is a possibility of remaining hypothyroid.

Thyroid destruction secondary to radioactive iodine or surgery: Patients who have been treated for a hyperthyroid condition (such as Graves' disease) and received radioactive iodine may be left with little or no functioning thyroid tissue after treatment. The likelihood of this depends on a number of factors including the dose of iodine given, along with the size and the activity of the thyroid gland. If there is no significant activity of the thyroid gland six months after the radioactive iodine treatment, it is usually assumed that the thyroid will no longer function adequately. The result is hypothyroidism. Similarly, removal of the thyroid gland during surgery will be followed by hypothyroidism.

Pituitary or Hypothalamic disease: If for some reason the pituitary gland or the hypothalamus are unable to signal the thyroid and instruct it to produce thyroid hormones, a decreased level of circulating T4 and T3 may result, even if the thyroid gland itself is normal. If this defect is caused by pituitary disease, the condition is called "secondary hypothyroidism." If the defect is due to hypothalamic disease, it is called "tertiary hypothyroidism."

A pituitary injury may result after brain surgery or if there has been a decrease of blood supply to the area. In these cases of pituitary injury, the TSH that is produced by the pituitary gland is deficient and blood levels of TSH are low. Because the thyroid gland is no longer stimulated by the pituitary TSH, hypothyroidism results. This form of hypothyroidism can, therefore, be distinguished from hypothyroidism that is caused by thyroid gland disease, in which the TSH level becomes elevated as the pituitary gland attempts to encourage thyroid hormone production by stimulating the thyroid gland with more TSH. Usually, hypothyroidism from pituitary gland injury occurs in conjunction with other hormone deficiencies, since the pituitary regulates other processes such as growth, reproduction, and adrenal function.

Medications: Medications that are used to treat an over-active thyroid (hyperthyroidism) may actually cause hypothyroidism. These drugs include methimazole (Tapezole) and propylthiouracil (PTU). The psychiatric medication, lithium, is also known to alter thyroid function and cause hypothyroidism. Interestingly, drugs containing a large amount of iodine such as amiodarone (Cardorone), SSKI, and Lugol's solution can cause a decrease in thyroid function, thereby resulting in low blood levels of thyroid hormone.

Severe Iodine Deficiency: In areas of the world where there is an iodine deficiency in the diet, severe hypothyroidism can be seen in 5 to 15% of the population. Examples of these areas include Zaire, Ecuador, India, and Chile. Severe iodine deficiency is also seen in remote mountain areas such as the Andes and the Himalayas. Since the addition of iodine to table salt and to bread, iodine deficiency is rarely seen in the United States.

What are the symptoms of hypothyroidism?

The symptoms of hypothyroidism are often subtle. They are not specific (which means they can mimic the symptoms of many other conditions) and are often attributed to aging. Patients with mild hypothyroidism may have no signs or symptoms. The symptoms generally become more obvious as the condition worsens and the majority of these complaints are related to a metabolic slowing of the body. Common symptoms are listed below:

Fatigue
Depression
Modest weight gain
Cold intolerance
Excessive sleepiness
Dry, coarse hair
Constipation
Dry skin
Muscle cramps
Increased cholesterol levels
Decreased concentration
Vague aches and pains
Swelling of the legs

As the disease becomes more severe, there may be puffiness around the eyes, a slowing of the heart rate, a drop in body temperature, and heart failure. In its most profound form, severe hypothyroidism may lead to a life-threatening coma (myxedema coma). In a severely hypothyroid individual, a myxedema coma tends to be triggered by severe illness, surgery, stress, or traumatic injury. This condition requires hospitalization and immediate treatment with thyroid hormones given by injection.

Properly diagnosed, hypothyroidism can be easily and completely treated with thyroid hormone replacement. On the other hand, untreated hypothyroidism can lead to an enlarged heart (cardiomyopathy), worsening heart failure, and an accumulation of fluid around the lungs (pleural effusion).

Did you know that nearly 11 million of us have a hypo-active thyroid? And that Hypothyroidism is linked to obesity and high cholesterol?

Fortunately there’s help…

Hypothyroidism, also called under-active thyroid, is a condition in which the thyroid gland doesn’t produce enough thyroid hormone to regulate the needs of the body. Even though it’s linked to many of our modern day ills, many of us are unaware that our thyroid may be the culprit.

Hypothyroidism is often misdiagnosed by doctors, because the symptoms are so diverse and vary with each person. Sometimes doctors attribute your symptoms to other causes.

Think back to those years when you felt fabulous! You had energy to burn, passion for living, and a feeling of vitality that carried you through the day and night. You were feelin’ fine!

Did your “get up and go” just get up and leave?

Are you one of those 11 million people thinking, “I guess I’m just getting old,” and wishing it weren’t true? Do you feel blue and depressed? Is your skin dry? Do you have brittle hair? You don’t understand why you’re gaining weight, and your hands and feet are always cold.

According to the famed Mayo Clinic, these are all symptoms of hypothyroidism.

HOW THYROMINE SUPPORTS YOUR OVERALL HEALTH

Ultra Herbal, a global herbal supplement company, recognized the need to make a safe, wholesome supplement that would assist sluggish thyroid function and give people relief from the debilitating effects of hypothyroidism.

Thyromine The thyroid gland is part of your endocrine system. It is located just above your collarbone at the base of your throat and is shaped like a butterfly. This little gland has the job of regulating your basal metabolism, or of converting heat (your calories) to energy.

When the gland becomes damaged, it can no longer produce proper levels of thyroid for optimal body function. The pituitary gland, which is the master gland of the endocrine system, tells the thyroid to make more thyroid hormone, but sometimes it just can’t make enough hormones to keep your body functioning normally.

Many things can contribute to a decline in thyroid hormone output. Thyromine Your thyroid could be damaged from a serious illness, which required work from your immune system. A trauma or accident could contribute to the problem. Or the thyroid can be injured by over-exposure to toxins, chemicals, pesticides, or radiation.

To function at it’s best, the thyroid gland requires iodine from sea vegetables (like sea weeds) and some vegetables. It also needs amino acids from meat, poultry and fish. In other words, like the rest of your body, the thyroid gland requires a healthy diet.

THE QUIET DANGERS OF BEING HYPOTHYROID

There is no cure for hypothyroidism, yet. Damaged thyroid cells do not re-grow. If left untreated, the symptoms will gradually increase, and in rare cases can even lead to cardiac involvement and death.

THE TRUE STORY BEHIND THYROMINE

Thyromine is truly a son’s gift to his mom. The need for a natural formula came from personal experience. The mother of one of the directors of Ultra Herbal was diagnosed with hypothyroidism. At that time her only choice was the synthetic thyroid prescribed by her doctors. Although she took the medicine, she was miserable with the side effects.

Thyax is a high-potency supplement, designed to adjust the metabolic and nutritional alterations caused by underactive thyroid disease, or hypothyroidism.

Hypothyroidism is more common than one might expect. Currently, hypothyroidism is the most common pathological condition related to a hormone deficiency. It is estimated that 3-5% of the entire population suffers from some form of this condition. Getting to the root of this deficiency is critical as many conditions can arise if hypothyroidism is not definitively diagnosed. Today, medical treatments for hypothyroidism are geared towards hormone replacement.

Although chances are you will eventually require replacement hormone medications, this does not mean that you should neglect the fact that your thyroid gland has nutritional needs of its own. Thyax has been developed for this purpose. Thyax supplies the body with the nutrients needed by the pituitary gland to activate the production of sufficient amounts of circulating thyroid hormone, thereby allowing for normal functioning of the thyroid to take place.

Thyax can be used to reset the balance of nutrients utilized by the thyroid gland. By providing your body with specific vitamins, minerals, and amino acids that support the thyroid, you regain a balance of the many thyroid-related chemical reactions which take place in the body on a daily basis.

Anyone can develop hypothyroidism. However, women older than 40 years of age have the greatest chance for onset. Generally, for both sexes, risk factors do increase as our metabolic rates continually decline with age. Other potential risk factors and at-risk populations include; having a close relative with an autoimmune disease, diabetics, pregnant women, those who are taking anti-thyroid medications or have received radioactive and radiation treatments, as well as persons who have had thyroid surgery (thyroidectomy).

Thyax: Your Natural Alternative to Conventional Thyroid Drugs

The most common treatments for hypothyroidism are prescription medications. Existing as synthetic thyroid hormone, these popular medicines are intended to replace the T4 hormone, which the body naturally produces. However, many patients have failed to respond to such treatments. Many physicians point to the lack of T3 in such medicines as the cause for little or no symptom relief in a large number of persons with hypothyroidism. Because of this, a growing number of individuals within the medical community have supported the use of natural or alternative therapies for hypothyroidism support.

As mentioned, the thyroid does require its own nutritional support for optimal health. Thyax accomplishes this by supplementing nutrients into the body that can support thyroid functioning on a permanent basis. Proper thyroid function requires adequate amounts of B-vitamin compounds, zinc, iodine, and copper; nutrients found in Progressive Health’s thyroid support formula. In addition to these thyroid supporting nutrients, Thyax also includes an L-tyrosine complex and L-phenylalanine; amino acids which are integral for the production of the neurotransmitters associated with hormone production, as well as the stability of endocrine glandular processes.

By stimulating the thyroid with natural components, Thyax not only eliminates the many adverse reactions and side effects of conventional thyroxine drugs, but may potentially restore normal thyroid hormone levels, relieve hypothyroidism symptoms, and reverse of any metabolic abnormalities associated with lowered thyroid hormone levels.

“My wife has had a borderline thyroid problem for years. Recently it started to get worse. We found out about your product and she has had great success.

I have been on synthroid for over 5 years. I did not perceive any real problems. When my wife had success with your product, I decided to switch. I decided that I would stop synthroid one day and start your product the next. The only side effect that I noticed was on the first evening. I had a “buzz” of “high”. This did not continue after the first night.

To date neither of us has hand any additional side effects. I did not realize the side effects that I was having from synthroid: excessive sweating, falling asleep watching TV, lack of ambition. My wife says I am a different person. My wife’s thinning hair has begun to thicken up.

One effect that we both noticed is that our allergies seemed to have disappeared. My wife was taking 3-5 antihistamines per week and I was taking 2 or 3. Since the first week, neither of us has taken and antihistamine.”

Thank you.
