The thyroid gland also secretes calcitonin. The thyroid’s C-cells are stimulated to secrete calcitonin when there is a high concentration of calcium in the blood stream. The function of calcitonin is to inhibit the amount of resorption of calcium from the bone and to regulate the amount of calcium in the blood stream.”
How Can Thyroid Problems Affect The Eye?
People with excess thyroid hormones (Graves’ disease) can develop many eye problems. One characteristic symptom is a protrusion of the eye (exophthalmos), in which the person appears to be staring or the eyelids tend to pull back from the eye. The tissues and muscles around the eye appear swollen, and this swelling (or edema) contributes to the eye protruding. In this state the eye can become dangerously dry, resulting in damage to or ulceration of the cornea, the clear outer covering of the eye. The person may also experience double vision. In severe cases, the optic nerve connecting the eye to the brain may become damaged, leading to blindness.”
Soy, wintergreen, turnips and walnuts may also be a problem to those vulnerable to low thyroid. Tobacco (although it’s not part of anyone’s “diet”, per se) and sugar have also been shown to have a negative impact on thyroid health.
Because of the thyroid’s connection to the immune system, people with allergies may find that the allergens to which their bodies react can affect thyroid health, as well.”
(1) Psychological stress: This is significantly affected not only by the number and intensity of potentially stressful factors in our life, but more significantly by our strategies for dealing with stress which ultimately determine the degree to which these factors affect us. Personality factors are also important, such as being high-strung, extremely ambitious or aggressive, or a tendency to experience a lot of anger also tend to create significantly more stress in our life.
(2) Dietary factors: Excess consumption of sea vegetables, iodized salt, tyrosine supplements and stimulants such as caffeine can contribute to hyperthyroidism. Excessive consumption of raw vegetables and herbs from the Mustard family (e.g. arugala, broccoli, Brussels sprouts, cabbage, cauliflower, kale, mustard greens, rapini, etc.) and Mint family (e.g. basil, bugleweed, catnip, lavender, lemon balm, marjoram, motherwort, oregano, peppermint, rosemary, spearmint, thyme, etc.) and soy products, and deficiencies of iodine, zinc and vitamins A, B2, B3, B6 and E can contribute to hypothyroidism.
(3) Drugs: Estrogen therapies opium derived drugs can contribute to hyperthyroid, while androgens, corticosteroids and salicylates may be implicated in hypothyroid.
(4) Exercise: Lack of exercise can contribute to both hyper- and hypothyroidism, as can insufficient sleep.
(5) Toxicity: Many toxins can bind to hormone receptor sites resulting in negative health consequences. Also of particular importance for thyroid function is radioactive iodine which is a by-product of nuclear fission from power plants and weapons testing. Iodine is an important component of thyroid hormone and these substances tends to be found in the highest concentrations in our thyroid.
(6) Autoimmune factors: Many cases of both hyper- and hypothyroidism have an autoimmune component. Psychological and toxic stress are major factors contributing to the development of autoimmune conditions.
(7) Tumours: Cysts and tumours of the thyroid can result in hyper- and hypothyroidism. One of the major causes of tumours in this organ is radioactive iodine.
(8) Iatrogenic causes: Post-therapeutic hypothyroidism can occur from over-zealous treatment of hyperthyroidism resulting in destruction or removal of too much thyroid tissue.
Foods and herbs from the Mustard and Mint families are very nutritious and many have important medicinal properties. Regular consumption of these plants will not lead to underactive thyroid function unless other factors are also involved, particularly iodine deficiency, which is rare since the advent of iodized salt. Only those who already have hypothyroidism need be concerned. In these cases foods from the Mustard family should be reduced, but not eliminated from the diet and only eaten cooked. Spices and herbs from the Mint family aren’t as much of a concern because they aren’t consumed in as large a quantity. However, regular consumption of herbal products containing bugleweed, motherwort and lemon balm should be avoided.”
In women, a weight gain of 29 pounds increased the risk of cancer in the uterus and gall bladder by nearly 60 percent, esophagus by 51 percent and kidney by 34 percent, the study said.
BPA is known to mimic estrogen and has been linked to early puberty in girls, attention deficit and hyperactivity disorder, and obesity.
That’s mainly because of a 2007 Health Canada panel that recommended the fluoride levels in water be reduced. The drug, which is said to help remineralize the enamel in teeth, thus helping to prevent cavities, has been tentatively linked to a rare type of bone cancer like the type Terry Fox had, not to mention the possibility of reduced intelligence in children and impaired thyroid functionality.
