Hypothyroidism – Low Thyroid Function

Hypothyroidism – Low Thyroid Function

The thyroid gland, located in the neck, plays a role in metabolism, heat regulation and energy levels. Thyroid hormones are required by every cell in the body and when the thyroid gland is under functioning it may lead to many symptoms.


  • Tiredness
  • Cold hands and feet
  • Poor sleeping
  • Hair loss
  • Weight gain
  • Low libido
  • Constipation.
  • Depression
  • Dry skin
  • Infertility

Thyroid function can be tested via A Simple Thyroid Test

Contributory Factors

Poor nutrition – The building blocks of thyroid hormones are tyrosine, which comes from protein, and the mineral iodine. In addition the minerals selenium, iron, zinc and copper are needed to convert thyroid hormones into their active form. Deficiencies of any of these nutrients, consumption of high levels of substances that deplete them or high levels of factors that stop them being absorbed can all lead to impaired thyroid function. Low tyrosine levels can be detected in An Amino Acid Profile. Smart Nutrition can assess your dietary levels of other important nutrients and put together a specific diet and supplement plan for you to correct any deficiencies and boost thyroid function. Amino Acid Profile.

Imbalance in essential fatty acids – Both essential fatty deficiency and essential fatty acid excess can compromise thyroid function. To ensure you have optimal levels you might like to have  A Fatty Acid Analysis.

Stress – Some of our stress hormones are also made from tyrosine, so at times of chronic stress the body’s resources get diverted leaving thyroid function compromised. In addition the body’s main stress hormone cortisol stops thyroid hormones form being converted to their more active form, which further compounds the problem. If you have a stressful lifestyle and suffer from some of the symptoms mentioned above you might want to consider an  adrenal/thyroid  test which combines testing for your thyroid hormones with testing for your stress hormones so that the impact of one set of hormones against the other can be measured.

Toxic metals – Certain toxic metals such as mercury and lead can interfere with the conversion of thyroid hormones to their active form. High levels of these minerals can be detected by a hair mineral analysis test. If toxicity is identified Smart Nutrition could put together a specific detoxification program for you to help remove the metals and restore thyroid function. Hair Mineral Analysis

Hormonal imbalance – When there is an excess of the female reproductive hormone oestrogen, it can block the action of the thyroid hormones. This means that even when the thyroid is producing normal levels of hormones, symptoms of hypothyroidism appear. This is common during the menopause. If you think hormone imbalances may be playing a role in your hypothyroid symptoms you may like to consider a comprehensive female hormone profile. The results can then be used by a nutritional therapist, in combination with any thyroid test results either from your Gp or from here to put together an effective treatment plan that will tackle any hormonal imbalances and boost thyroid function. Comprehensive Female Hormone Panel.

Oxidative stress – This term refers to high levels of the cell damaging molecules called free radicals. Excessive free radical production can result from sources such as environmental pollutants, cigarette smoke, drugs and radiation and here is growing evidence supporting their role in disease. They are known to suppress thyroid hormone production and prevent conversion of thyroid hormones to their active form. An oxidative stress analysis can be used to measure the body’s oxidative stress status and give an indication whether this is a contributing factor to your low thyroid function. Oxidative Stress Test.

Low liver function – The liver is the organ responsible for converting thyroid hormones to their active form. If it is not working efficiently then the thyroid hormones can’t do their job properly. .
