Hyperthyroidism is when the thyroid gland produces excess thyroid hormones, resulting in a variety of symptoms that indicate poor overall health. According to a study published in the "American Journal of Clinical Nutrition" in 1984, hyperthyroidism often correlates with lowered zinc levels, which can further complicate overall health. Zinc is a mineral necessary to many aspects of body health and function.
Hyperthyroidism
Hyperthyroidism --- the increased production of thyroid hormone --- can be a consequence of several factors. The Thyroid Foundation of Canada states that Graves' disease, also known as Graves-Basedow disease, is the most common cause of hyperthyroidism. Treatments detailed by the foundation include the use of antithyroid drugs, surgery and radioactive iodine treatments. While these are some common treatments for hypothyroidism and Graves' disease, all treatment should be pursued only with the advice of a personal physician or health care professional.
Symptoms of Hyperthyroidism
The Thyroid Foundation of Canada lists the following as common symptoms of hyperthyroidism: weight loss, nervousness, excess sweating, muscle weakness, shakiness and irritability. Other symptoms include a rapid pulse, goitre --- where the thyroid becomes enlarged --- and very moist skin. Hyperthyroidism is also commonly associated with lowered zinc levels, as the body tries to excrete zinc as a consequence of high thyroid hormone levels. Lowered zinc levels can interfere further with overall body health as zinc is a necessary mineral for many body functions, including at the cellular level.
Zinc and Bodily Function
An important trace mineral, zinc can be found throughout the body. It is second only to iron for mineral concentration in the body. Zinc helps the body's immune system work properly by aiding in cell growth and division, as well as helping to break down carbohydrates. Zinc also affects sense of smell and ability to taste. In addition, it is beneficial in helping heal wounds in the body.
Zinc Deficiency and Zinc Consumption
Symptoms of zinc deficiency, as described by Medline Plus, an online resource of the National Institutes of Health, include higher occurrences of infections, both bacterial and viral; hair loss; decreased appetite; skin sores; stunted growth; difficulty seeing in the dark; wounds that take longer than usual to heal; problems with taste or scent; and in males, hypogonadism, where the male sexual glands produce very little or no hormones at all.
For those with a zinc deficiency, Medline Plus suggests eating beef, pork and lamb, which contain high levels of zinc. Nuts, whole grains, yeast and legumes are also good sources of zinc. Zinc is widely available as a mineral supplement or as part of a multivitamin. However, overconsumption of zinc can lead to diarrhea, abdominal pain and vomiting.
