I seem to be attracting a number of clients suffering from either an under-functioning thyroid (hypothyroidism) or an over functioning thyroid (hyperthyroidism). However, lets talk about an over-functioning thyroid. Common signs and symptoms of an over functioning thyroid include a racing pulse, palpitations, swelling at the base of the neck, moist skin and increased perspiration, shakiness or tremor, nervousness, confusion, increased appetite accompanied by weight loss, difficulty sleeping, swollen reddened bulging eyes, sensitivity of eyes to light, irregular menstrual cycle. If you have read through each of the aforementioned signs and symptoms listed and have ticked the majority you should have your thyroid function assessed via your health care practitioner. With an over functioning thyroid the thyroid gland produces too much thyroid hormone and in doing so increases a persons metabolic rate- the faster your metabolism works the more likely you will lose weight. Now before you begin to wish for an over functioning thyroid, lets get clear about how seroius a condition this can be. Left untreated an over functioning thyroid can be fatal! The condition can take three different forms: Grave's disease (noticeable goitre), Toxic Nodular Goitre (non-cancerous tumours in the thyroid produce too much thyroid hormone) and Secondary Hyperthyroidism (pituitary gland in the brain stimulates the thyroid to produce too much thyroid hormone). Risk factors for an under functioning thyroid include stress, pregnancy, intestinal dysbiosis (digestive problems), antibiotic over-usage or a family history of thyroid conditions. If you suspect you have an over functioning thyroid discuss with your health care practitioner the following tests: TSH (this is your thyroid stimulating hormone); Free T3 (a hormone that assists with thyroid function); Free T4 (a hormone that assists with thyroid function); Anti-TPO Antibodies ( for Grave's disease); Anti-thyroglobulins (for Grave's disease). It is very possible to have a normal TSH level, yet have elevated levels for each of the other blood tests I have mentioned, for this reason a full assessment of your thyroid is of benefit.
