Hyperthyroidism and Kelp

Filed by author in Kelp 0 Comments

Hyperthyroidism or overactive thyroid happens when the thyroid gland goes into overdrive and produces too much thyroxine, which is the thyroid hormone. Hyperthyroidism can result in an abnormal increase in the body’s metabolism rates. This can cause irregular and rapid heart beat, sudden weight loss, nervousness, irritability and sweating. Other symptoms of hyperthyroidism are increased appetite, changes in pattern of menstruation, trembling of fingers and hands, increased heat sensitivity, difficulty sleeping, muscle weakness, fatigue, increased and frequent bowel movements and an enlarged thyroid gland. The enlarged thyroid gland will show as a swelling at the base of the neck and is called goiter.

There are various causes of hyperthyroidism – toxic adenoma, Graves’ disease, Plummer’s disease or thyroiditis. The thyroid gland and its hormones are critical for maintaining body temperature, regulate protein production, maintain optimal heart rate and it affects the way the body utilizes carbohydrates and fats. It also produces calcitonin which a calcium regulating hormone.

Hyperthyroidism can be treated using anti-thyroid medications. Sometimes or a portion of the thyroid gland will be surgically removed. Hyperthyroidism must be treated at once to prevent complications. Most people respond well to treatment.

Kelp Benefits for Hyperthyroidism

Deficiency in iodine can cause brain damage, mental retardation, goiter, developmental and growth abnormalities and such. According to the WHO, around 30% of the entire population of the world (which accounts for around 2 billion people) suffers from iodine deficiency. This deficiency is mainly due to poor quality of soil in many regions. The recommended daily dosage of iodine is 1.1mg (upper limit).

While an excess of iodine through supplements can cause hyperthyroidism, there are many studies which suggest that kelp and its supplements do not have such high levels of iodine to cause toxicity and lead to thyroid problems. However, in the case of a 39-year old woman with hyperthyroidism and enlarged thyroid, without any genetic predisposition to thyroid disorders,  it was found that she had been given an overdose of kelp supplements. She had been on an herbal kelp tea diet prescribed by a Chinese alternative medicine practitioner for four weeks. This caused an overdose of iodine and symptoms of hyperthyroidism.

She required anti-thyroid drugs to treat her condition.  Hence, while iodine content in kelp can benefit thyroid disorders, the intake must be regulated.

Kelp maybe discontinued a few weeks before or after surgery or before an X-ray is due which requires contrast media.
