Functions of the Thyroid

The thyroid is a small ductless gland weighing less than one ounce, located in the neck along the trachea or windpipe. The thyroid is the only place where iodine can be absorbed into the body.


Iodine comes from the different foods we eat and is necessary in small quantities to make thyroid hormones: triiodothyronine (T3) and thyroxine (T4).  These hormones are then circulated throughout the body where they control metabolism in every cell.  Metabolism is the body’s conversion of oxygen from the air we breathe and calories from the food we eat to energy.


What is Hypothyroidism?

“Hypo” means too little or under normal, and “thyroidism” is the disease of the thyroid. Therefore, “hypothyroidism” is the disease of too little thyroid activity or decreased thyroid activity.

Hypothyroidism is the result of too little thyroid hormone. This can happen when the thyroid does not produce enough hormones, an under-active thyroid, OR the thyroid produces enough hormones, but the hormones break down too quickly and cannot be used by the body.


Causes of Hypothyroidism

  1. Thyroid produces too little hormone.
  2. Hashimoto’s disease – the body creates an allergy to thyroid hormones, destroying them, and causing low hormone levels
  3. Undiagnosed thyroid problems – normal laboratory levels of thyroid hormones T3 & T4, but have reoccurring or non responsive health problems; often, patients do better when supplemented with thyroid nutrients or hormone.
  4. Viral infection may onset inflammation of the thyroid gland, causing hypothyroidism.

  1. Before falling asleep each night, keep the thermometer next to your bed.
  2. In the morning before rising out of bed, lie still, and take your temperature under the armpit for 15 minutes. Do this except on the first few days of your period and the middle of the menstrual cycle.
