T4 circulates through to the liver where 60% of it is converted into T3 through the glucoronination and sulfation pathways. If the liver is sluggish it will cause a problem in T4-T3 conversion (6). Another 20% is converted into reverse T3 which is permanentely inactive. The final 20% is converted into T3 sulfate and T3 acetic acid which can then be further metabolized by healthy gut bacteria to produce more active T3 (6).
People who have been treated for hyperthyroidism (underactive thyroid) like Graves' disease, and received radioactive iodine may be left with little or no functioning thyroid tissue after treatment. The likelihood of this depends on a number of factors including the dose of iodine given, along with the size and the activity of the thyroid gland. If there is no significant activity of the thyroid gland six months after the radioactive iodine treatment it usually means that the thyroid gland no longer functioning adequately. The result is hypothyroidism. Similarly, removal of the thyroid gland during surgery cause hypothyroidism.
The purpose of treating hypothyroidism is to maintain normal metabolism by correcting a deficient output of thyroid hormone. Once replacement therapy begins, the thyroid will stop producing hormones all together, and replacement must be continued for life. Most mainstream physicians prescribe the drug Synthroid, also known as levothyroxine, a synthetic analog of thyroxine (T-4) and monitor how much to give based on symptoms and levels of TSH. Physicians will generally check TSH levels after a couple of months of being on the medication and adjust it accordingly. They will often used a more cautious course in patients who have cardiovascular disease. This allows the heart time to adjust to an artificially increased metabolism. Side effects of taking too much thyroid hormone include shakiness, palpitations, insomnia and changes in appetite.
Hi, Dawn: Yes, there’s definitely a TON of conflicting information out there. When it comes to cruciferous vegetables and the thyroid, it’s all about raw veggies, not cooked. Raw cruciferous veg contains a compound called goitrogens, which might impact thyroid function by impairing thyroid peroxidase, an enzyme normally found in the thyroid gland. I don’t think this means that you should NEVER eat a single serving of raw cruciferous veggies if you have thyroid issues. But just that you shouldn’t overdo it and eat raw daily. Hope that helps!
Medication is the first option as treatment for hypothyroidism. Doctors may prescribe different medications to bring the production of thyroid hormone to normal levels. However thyroid medications tend to react differently to different people and it may take a while to find the drug that best suits your individual case. In the meantime, you can also try some natural remedies for hypothyroidism. Always make it a point to keep your doctor in the loop however, as most natural treatments have not been subjected to rigorous testing and some could in fact have an adverse effect or interfere with the action of medications. The use of exercise and supplements is thought to help in the natural treatment of hypothyroidism. Including an hour of exercise at least thrice a week is important for the treatment of hypothyroidism. In addition to this, you can speak to your doctor about what supplements you should be having along with the proper dosages.
Chromium picolinate, which is marketed for blood sugar control and weight loss, also impairs the absorption of thyroid medications. If clients decide to take chromium picolinate, they should take it three to four hours apart from thyroid medications.23 Flavonoids in fruits, vegetables, and tea have been shown to have potential cardiovascular benefits. However, high-dose flavonoid supplements may suppress thyroid function.24 The Natural Standards Database provides an extensive list of supplements that have a potential impact on thyroid function, so taking precautions and coordinating patient care with a knowledgeable practitioner is prudent.
If you suffer from hypothyroidism, you should not eat them raw. Goiter is a substance that inhibits iodine uptake to create the T4 hormone. The family of crucifers are: bok choy, broccoli, Brussels’ sprouts, cabbage, cauliflower, kale, mustard greens, radishes, soy, soy milk, soy lecithin (often used as a filler in vegetarian food) and tofu. Cooking them reduces their goitrous properties, however, so they can still be an important part of a diet for thyroid health.
The thyroid gland needs iodine, therefore if you have an underactive thyroid gland you should increase the iodine intake in your diet. A well-balanced diet that includes iodine can help in alleviating the symptoms that you encounter with your condition. With the simplest intake of the foods mentioned above, you can greatly assist your thyroid in keeping up with your body's metabolism. (See Hypothyroidism and Iodine for more information)
In some areas of the world, iodized salt is an essential way to prevent iodine deficiency, cretinism, and mental retardation due to iodine deficiency in pregnant women. In the United States, however, many people have limited their salt intake or stopped using iodized salt, and you need enough iodine for the thyroid to function properly. An excess of iodine, however, is also linked to increased risk of thyroid disease, so staying in range and avoiding deficiency or excess is essential.
Try this: Purée raw pumpkin seeds with avocado chunks, cilantro, and a squeeze of lime for a creamy twist on guacamole. Combine pumpkin seeds, canned black beans, shredded carrots, and instant oats in a food processor; pulse until finely chopped and form into burgers; fry until crispy on the outside and cooked through. Or toss pumpkin seeds with melted butter or coconut oil, honey, cinnamon, and cardamom, and toast in the oven at 300°F until browned.
Probiotic-Rich Foods – These include kefir (a fermented dairy product) or organic goat’s milk yogurt, kimchi, kombucha, natto, sauerkraut and other fermented veggies. Part of your hypothyroidism diet, probiotics help create a healthy gut environment by balancing microflora bacteria, which reduces leaky gut syndrome, nutrient deficiencies, inflammation and autoimmune reactions.

You need to reduce the toxins you ingest from additives, preservatives, artificial sweeteners (!), excessive sodium, and trans-fats and try to eliminate toxins hiding around your house. Water toxicity is a HUGE problem in thyroid conditions. Most public water systems in the US have fluoride added, which is now linked to slowing down the thyroid; fluoride is believed to be leaching on to the thyroid cells inhibiting the uptake of iodine, hence the altered production of the thyroid hormone (T4).
Fruits and veggies - Colorful foods like berries, grapes, dark leafy greens, and most other fruits and vegetables are high in healthy antioxidants, which helps your body build up its immune system and stave off unwanted diseases. Given that hypothyroidism is often a consequence of autoimmune diseases, building up that immune system is key to helping prevent your hypothyroidism from progressing.
The disease process for Hashimoto’s is a spectrum, and not all patients require treatment. Some patients have autoimmune antibodies but retain enough thyroid function without the need for intervention for years. Generally, once the body can no longer produce an adequate amount of thyroid hormone for necessary physiological functions, thyroid replacement medication is necessary to correct the hormonal imbalances associated with hypothyroidism.
From the early 1890s through the mid-1970s, desiccated thyroid was the preferred form of therapy for hypothyroidism (Appendix Table, available at www.annals.org). This preference was reinforced by the unique ability of desiccated thyroid to reproduce a normal serum PBI (33). The predominance of natural thyroid products was illustrated by prescribing patterns in the United States: In 1965, approximately 4 of every 5 prescriptions for thyroid hormone were for natural thyroid preparations (38). Concerns about inconsistencies in the potency of these tablets arose (26) after the discovery that some contained anywhere from double to no detectable metabolic activity (39). The shelf-life of desiccated tablets was limited, especially if the tablets were kept in humid conditions (36). There were reports of patients not responding to desiccated thyroid altogether because their tablets contained no active thyroid hormone. It was not until 1985 that the revision of the U.S. Pharmacopeia standard from iodine content to T3/thyroxine (T4) content resulted in stable potency (38), but by then the reputation of natural thyroid products was tarnished (40).
The most common treatment I use is Armour thyroid, (9) a prescription drug made from desiccated (dried) porcine thyroid. It contains the full spectrum of thyroid hormones, including T4, T3, and T2 (10). That last one – T2 – is a little-known product of thyroid metabolism that actually may be very important. The right dose ranges from 15 to 180 milligrams, depending on the person.
Autoimmune disease - Autoimmune disorders occur when the body’s immune system produces antibodies that attack its own tissues. Scientists aren’t sure why the body produces these antibodies and why it would attack itself. Some think that a virus or bacterium might trigger this, while others believe that genetic factors cause autoimmune disorders. It could also be a combination of the two factors. Regardless of the cause of autoimmune diseases they are thought to be a cause of hyperthyroidism. When the immune system attacks the body, it often targets the thyroid. This limits the thyroid’s ability to produce hormones and results in hyperthyroidism.
Megan Casper, RDN, a dietitian based in New York City and the founder of Nourished Bite, points out that iodine deficiency is the leading cause of hypothyroidism worldwide. This mineral can’t be made by the body, so dietary sources like iodized salt, dairy products, seafood, seaweed, and fortified cereals are important. “Iodine is an essential nutrient in the body, and thyroid hormones are composed of iodine,” explains Rizzo. “Those lacking thyroid hormones may also be lacking iodine.”
