Hypothyroid or Underactive Thyroid

What is hypothyroidism?

Hypothyroidism is a condition in which your body lacks sufficient thyroid hormone. Often our naturopathic doctor will see clients who have had their thyroid hormones tested with “normal” results, but they are exhibiting many, if not all, of the symptoms of an underactive thyroid. This is referred to as subclinical hypothyroidism and responds very well to naturopathic treatment.

What Causes Hypothyroid?

  1. The most common reason for an underactive thyroid is a condition known as Hashimoto’s or Hashimoto’s thyroiditis.  It is an autoimmune disorder where your body is attacking your own thyroid and destroying the tissue.  While this is happening, blood tests may be inconsistent and may even show normal levels of TSH, free T3 and free T4. Most patients, even those with obvious thyroid disease, have never been tested for Hashimoto’s. There are blood tests available for this that our naturopathic doctor will order.  These blood tests check for anti-TPO antibodies and anti-thyroglobulin.
  2. Nutritional deficiencies.  Your thyroid needs iodine, zinc, selenium, copper and tyrosine to do its job properly. A deficiency of any of these nutrients prevents your thyroid from working right.
  3. Poorly functioning endocrine system.  All of the parts of your endocrine (hormone-producing) system work together.  If one part isn’t working well, it negatively impacts the others.

What are the symptoms of hypothyroidism (underactive thyroid)?

  • Fatigue
  • Weakness
  • Weight gain or difficulty losing weight
  • Hair loss
  • Muscle cramps and frequent muscle aches
  • Depression
  • Irritability
  • Memory loss
  • Abnormal menstrual cycles
  • Infertility

Natural Treatment for Hypothyroidism

As a Naturopath, I always try to address and treat the underlying cause of the problem.

Several factors influence healthy thyroid function:

  • nutrition and diet
  • vitamin and mineral status
  • stress
  • liver and adrenal gland function and
  • heavy metal (particularly mercury) toxicity.

My extensive intake procedure helps me determine whether diet changes, vitamins, herbs, liver support, endocrine system help, and/or acupuncture will be most appropriate for you. I can determine whether there are issues with your liver function, heavy metals, adrenal gland or HPA axis function, Hashimoto’s disease, and nutritional deficiencies.

Many of my clients have at least been able to reduce the dosage of their thyroid medications, avoid having to take thyroid medication, or enjoy better health and vitality by improving how well their body uses their existing medication.

Thyroid Blood Tests

Thorough testing for your thyroid includes the following tests: TSH, free T3, free T4, reverse T3, anti-TPO, and anti-thyroglobulin antibodies.  TSH, free T3, and free T4 numbers can all be normal even in Hashimoto’s disease.  The range of what is considered normal for TSH is quite broad – 0.35-5.00.  Many of my patients do not feel normal and exhibit many hypothyroid symptoms once their TSH level gets above 3.50.  For my infertility patients, I require their TSH to be below 2.50.  Our naturopathic doctor orders and interprets these lab tests for you and provides solutions that will get to the root of thyroid issues.
