Thyroid Goiter

Iodine is an essential dietary component that is needed to maintain normal thyroid function. Typical sources of iodine include, breads, chesse, cow’s milk, eggs, frozen yogurt, ice cream, iodized table salt, saltwater fish, seaweed, shellfish, soy milk and soy sauce.(1) Iodine deficiency has been almost completely eradicated in the United States since the introduction of iodized salt in the 1920′s-30′s. In the US, the Recommended Daily Allowance (RDA) for Iodine is 150ug per day.

Approximately 40% of the world remains at risk for iodine deficiency.(1)

The thyroid gland is made up of follicular cells. Thyroxine (T4) and Triiodothyronie (T3) are thyroid homones that are made inside the follicular of the thyroid gland. Dietary iodine is absorbed through the gastrointestinal tract and is then concentrated within the thyroid. It is then used by the follicular cell as an essential component of the thyroid hormones.

T3 and T4 are secreted from the thyroid gland under the regulation of Thyroid Stimulating Hormone (TSH) that is made in the anterior pituitary gland. TSH is released in response to low plasma levels of T3 and T4.

The majority of thyroid hormone is released from the thyroid gland as T4; however, once release from the thyroid, T4 is converted to T3. T3 is the metabolically active form of the hormone. T3 is responsible for increasing the body’s Basal Metabolic Rate (BMR). The BMR is the amount of energy that is expended by a person at rest. An increase in BMR leads to an increase in oxygen and energy consumption. T3 acts on the majority of tissues within the body.

A dietary iodine deficiency results in a deficiency in thyroid hormones (T3 and T4). The result can be hypothyroidism in adults, cretinism in children and in some cases nodular goiter.

A goiter is any swelling of the thyroid gland. Endemic goiter is a type of goiter that is associated with dietary iodine deficiency. Typically endemic goiter can be treated medically, however, in advanced cases where the mass encroaches upon or compresses nearby structures such as the trachea, surgical intervention is necessary.

The Struma Classification of Goiters:

Class I – only found by palpation.

Class II – can be easily seen.

Class III – large, pressure results in compression marks.

Thyroid Cancer

 The Rising Incidence of Thyroid Cancer in The New York Times. (October 14, 2010). The article, written by Carolyn Sayre points out,“…that the incidence has more than doubled since the early 1970s, and for women, it is the cancerwith the fastest-growing number of new cases.”(1)Similarly, Sabiston’s textbook of surgery agrees by saying, “Several studies have shown that the incidence of well-differentiated thyroid carcinoma has increased perhaps as much as 50% since 1990.”

And goes on to point out, that…“Whether this increase is due to enhanced sophistication in screening and diagnostic techniques or possible exposure to environmental factors such as radiation or environmental mutagenic chemicals is not clear.” (2)

Types of thyroid cancer include: Papillary (70-80%), Follicular (10%), Medullary (6%), Anaplastic (< 1%). Let’s concentrate on papillary:

  • Commonly associated with previous ionizing radiation
  • 3x more common in women
  • Typically present as asymptomatic nodule
  • Treatment:
    • <1cm: lobectomy & isthmectomy
    • 1-2cm: Controversial. total thyroidectomy vs. lobectomy & isthmectomy
    • 2cm: total thyroidectomy
    • Can metastasize to local lymph node
      • Spread to lymph nodes of the neck present in more than 50% of cases
      • Stage II-IV patients also undergo lymph node resection

Required Reading on The Obesity Epidemic

saltsugarfatSalt, Sugar, Fat is a must read book for anyone who has ever wondered why we are getting bigger.  Michael Moss explains the reasons behind the obesity epidemic.  

Every year, the average American eats thirty-three pounds of cheese and seventy pounds of sugar. Every day, we ingest 8,500 milligrams of salt, double the recommended amount, almost none of which comes from the shakers on our table. It comes from processed food, an industry that hauls in $1 trillion in annual sales. In Salt Sugar Fat, Pulitzer Prize–winning investigative reporter Michael Moss shows how we ended up here. Featuring examples from Kraft, Coca-Cola, Lunchables, Frito-Lay, Nestlé, Oreos, Capri Sun, and many more, Moss’s explosive, empowering narrative is grounded in meticulous, eye-opening research. He takes us into labs where scientists calculate the “bliss point” of sugary beverages, unearths marketing techniques taken straight from tobacco company playbooks, and talks to concerned insiders who make startling confessions. Just as millions of “heavy users” are addicted to salt, sugar, and fat, so too are the companies that peddle them. You will never look at a nutrition label the same way again.
