The Thyroid and its function

Posted by admin | Posted in articles, health | Posted on 29-10-2012


The thyroid is the regulator of your body and mind. The thyroid gland makes two hormones that are secreted into your blood: thyroxine (T4) which contains 4 atoms of iodine, and triiodothyronine (T3) which contains 3. These hormones are necessary for all the cells in your body to work as they should.

The hormones that the thyroid gland produces regulate the speed at which your cells function. If the gland produces too many or too few of these hormones the following problems occur:

Hypothyroidism – the cells and organs of your body slow down.

Hyperthyroidism – too much activity in your cells and organs.

The symptoms can range from feeling overly tired, drained and muddled headed, to feeling ‘pumped-up’, sweaty and anxious. A swollen or enlarged neck may be the result of hypo- or hyperthyroidism. Weight loss (unexpectedly) or weight gain can also be early signs. In short:

Hypothyroidism –

  • Dry skin and brittle nails.
  • Numbness and tingling of the hands.
  • Constipation.
  • Menstrual cycle irregularities.

Hyperthyroidism –

  • Muscle weakness or trembling hands.
  • Vision problems.
  • Diarrhoea.
  • Menstrual cycle irregularities.

If you feel as though you are presenting with any of the symptoms then contact your GP. the doctor will assess your symptoms and if deemed appropriate, recommend a blood test. If you are diagnosed as having hypothyroidism you will be prescribed thyroid hormone tablets. Once the course of medication takes effect you will notice a positive change which might include; more energy, lower cholesterol, and gradual weight loss.
