The thyroid gland is an endocrine gland that secretes hormones into the blood. These hormones are thyroxine (T4), triiodothyronine (T3) , and calcitonin. These hormones influence metabolism.

An overproduction of thyroid hormones causes hyperthyroidism. Problems associated with hyperthyroidism include weight loss, bulging eyeballs, tachycardia, nervousness and agitation.

Hypothyroidism is the opposite and can lead to problems such as weight gain, hair loss, swelling of tissues, bradycardia, hypotension and mental sluggishness. Myxedema is the disease of hypothyroidism in adults.

Thyroid is an endocrine gland located in the front of the neck. The thyroid absorbs iodine from the blood and uses it to make the active hormones thyroxine, also called tetraiodothyronine, and triiodothyronine.  These hormones control the body's cell metabolism.  Thyroid hormones released into the bloodstream, cells increase the rate at which they convert oxygen and nutrients into energy and heat for the body's use. Thyroid hormones also stimulates mental activity and increases the activity of the other hormone-producing glands.

Common problem associated with thyroid are under active thyroid, called hypothyroidism, and overactive thyroid, called hyperthyroidism. Hypothyroidism results in a reduced production of thyroid hormones.  causing an overall decrease in both physical and mental activity.  Symptoms of hypothyroidism appear in almost every organ system of the body.  These include the skin becoming dry and puffy, thinning of  hair which also become brittle,  slow speech, slow reflexes, poor memory, constipation, and fatigue.

Hyperthyroidism, results in an overproduction of thyroid hormones, causing an increase in the rate of most biological reactions.  Symptoms of hyperthyroidism include sweating, excessive nervousness, insomnia, and diarrhoea.

Symptoms of thyroid problem affect many people. In fact, about 13 million Americans experience one or more of the symptoms of problem with thyroid.


The function of the thyroid gland is to regulate the speed of the body's metabolism. In other words, this gland converts the food we eat into energy for the body.

When this gland is not operating properly, it causes all kinds of symptoms of thyroid problem described below, and it does not convert the food we eat into energy.


The thyroid gland makes two hormones, thyroxine-T4 (with four iodines) and triiodothyronine T3 (with three iodines). T4 blood levels are higher than those of T3, but T3 is four times more potent. Normally the body converts T4 to T3 as needed.


Common symptoms of problem with thyroid due to low thyroid or hypothyroidism are:



• Fatigue and weakness • Low basal temperature ( cold intolerance) • Dry and coarse skin • Hair loss • Cold hands and feet • Weight gain • Insomnia • Constipation • Depression • Poor memory, forgetfulness, dementia • Nervousness and tremors • Immune system problems • Heavy menstrual periods

Diseased or malfunctioning thyroid gland may lead to two conditions. One is called Hyperthyroidism, when the gland is overactive to release hormone more than what is needed. The other is called Hypothyroidsm, when the gland is underactive and unable to release the required quantum of thyroid hormone.

Both the conditions of thyroidism affect the metabolism, leading to a number of symptoms as listed hereunder:

* increasing obesity

* lack of energy, weakness, fatigue

* swelling in the neck, suggesting visible swelling of the thyroid gland

* problem in sleeping

* loose motion/ diarrhea

* visible swelling of cheeks

* swelling of eyes/eye-lids
