If for some reason the pituitary gland or the hypothalamus are unable to signal the thyroid and instruct it to produce thyroid hormones, it may cause decreased T4 and T3 blood levels, even if the thyroid gland itself is normal. If pituitary disease causes this defect, the condition is called "secondary hypothyroidism." If the defect is due to hypothalamic disease, it is called "tertiary hypothyroidism."
If you have subclinical hypothyroidism, discuss treatment with your doctor. For a relatively mild increase in TSH, you probably won't benefit from thyroid hormone therapy, and treatment could even be harmful. On the other hand, for a higher TSH level, thyroid hormones may improve your cholesterol level, the pumping ability of your heart and your energy level.
On the flip side, there are certain foods that people with underactive thyroids should minimize or avoid altogether, like cruciferous vegetables, particular raw Brassica vegetables like broccoli, cauliflower, cabbage, kale, soy, and Brussels sprouts. While these are healthy foods for most people, they contain a compound called goitrogens, which might impact thyroid function by impairing thyroid peroxidase. Gluten, conventional dairy, refined sugar and refined flour, caffeine and alcohol (which stress your adrenals) are also contraindicated for hypothyroid patients.
Gluten is the common protein found in wheat, barley, & rye. Gluten is a sticky, storage protein that is challenging for the digestive tract because it binds to the small intestinal wall where it can cause digestive and immune system disorders. Gluten sensitivity is an epidemic that is a major contributing factor with inflammatory and autoimmune diseases (61, 62).
The thyroid controls how your body's cells use energy from food, a process called metabolism. Among other things, your metabolism affects your body’s temperature, your heartbeat, and how well you burn calories. If you don't have enough thyroid hormone, your body processes slow down. That means your body makes less energy, and your metabolism becomes sluggish.
“Some evidence suggests that soy foods, by inhibiting absorption, may increase the dose of thyroid hormone required by hypothyroid patients. However, hypothyroid adults need not avoid soy foods. In addition, there remains a theoretical concern based on in vitro and animal data that in individuals with compromised thyroid function and/or whose iodine intake is marginal, soy foods may increase risk of developing clinical hypothyroidism. Therefore, it is important for soy food consumers to make sure their intake of iodine is adequate.” [Messina]
Hypothyroidism Diet: One of the main causes of hypothyroidism is inflammation, so following an anti-inflammatory diet is key to improving your thyroid function. Likewise, ensuring your diet is rich in nutrient-dense foods, particularly iodine and selenium, will also help your thyroid produce sufficient levels of thyroid hormones. Some of the best foods to eat for your thyroid: wild-caught fish, coconut oil and ghee, seaweed, probiotic-rich foods like yogurt, sauerkraut and miso, sprouted whole grains and nuts, fiber-rich fruits and vegetables, bone broth, and plenty of good ole’ H20. Getting plenty of protein, healthy fat and fiber is of utmost importance when you have thyroid dysfunction.
The thyroid produces hormones that regulate mood, metabolism, energy levels, body temperature, heart rate, and blood pressure. Hypothyroidism occurs when this gland isn't producing enough hormones. Along with taking your thyroid medication, you can bolster thyroid function with a well-balanced diet that includes lots of produce and protein, among other healthy foods, says Gregory B. Dodell, MD, an endocrinologist in New York City. The next time you're at the grocery store, look for these seven nutrient-rich foods.
As hypothyroidism becomes more severe, signs and symptoms may include puffiness around the eyes, the heart rate slows, body temperature drops, and heart failure. Severe hypothyroidism may lead to a life-threatening coma (myxedema coma). In a person with severe hypothyroidism, a myxedema coma tends to be triggered by severe illness, surgery, stress, or traumatic injury. Myxedema coma requires hospitalization and immediate treatment with thyroid hormones given by injection.
*Cassava bears special mention here. You may have heard of it because it is the starchy root vegetable from which tapioca is made, but cassava is also a popular staple food in many Third World countries, where it is eaten boiled, mashed, or ground into flour. Fresh cassava root contains a harmless substance called linamarin, which can turn into hydrocyanic acid (aka cyanide!) when the plant is damaged or eaten. Flaxseeds also contain linamarin. Cyanide is very toxic, so the human body converts it into thiocyanate (which, although it does interfere with thyroid function, is less toxic than cyanide and easier for the body to eliminate).
Supplementing with L-tyrosine has been shown to improve sleep deprivation and can help combat fatigue and a poor mood by improving alertness and neurotransmitter function. One reason L-tyrosine is beneficial in healing thyroid symptoms is because it plays a role in the production of melatonin, dopamine and/or norepinephrine, which are our natural “feel good” hormones. (17)
It is extremely important that women planning to become pregnant are kept well adjusted, since hypothyroidism can affect the development of the baby. During pregnancy, thyroid hormone replacement requirements often change, so more frequent monitoring is necessary. Various medications and supplements (particularly iron) may affect the absorption of thyroid hormone; therefore, the levels may need more frequent monitoring during illness or change in medication and supplements.
Most physicians diagnose hypothyroidism by simple blood tests that measure the level of TSH (thyroid stimulating hormone), which is made by the pituitary gland in response to thyroid hormone and the body’s needs, and indicates thyroid status. As levels of thyroid hormones fall, the pituitary releases TSH to stimulate the thyroid to produce more hormone. Clinicians may also measure circulating levels of T-3 and T-4, which are the thyroid hormones themselves. Low levels of T-4 and high levels of TSH reveal an underactive thyroid. Other variants of hypothyroidism can exist. Patients can have no symptoms and normal serum thyroid hormone levels, but elevated TSH. Others can have symptoms, but normal TSH and T-4 levels. Patients with either of these variants may benefit from supplementation. In addition, someone with a temporary illness might have a completely normal thyroid but high TSH, a condition called “sick euthyroid” which usually resolves without any intervention.
11. Methylation: Methylation is a key process that protects DNA, turns on and off genetic traits and helps to detoxify environmental chemicals. Many individuals have certain genetic polymorphisms that limit their ability to appropriately methylate. Methylation plays a very important role in T cell function and poor methylation status is associated with the development of auto-immunity (31).
Most people with hypothyroidism don’t need to steer clear of soy completely. But it’s a good idea to limit your consumption to a few servings a week, and to stick with minimally processed forms of soy like tempeh or miso. Foods containing processed soy protein isolates (like soy protein powder, soy protein bars, or soy-based meat analogs) tend to have a higher concentration of isoflavones, says Markley.
l-Thyroxine was the first synthetic molecule used to treat hypothyroidism (23) and was shown to be efficacious as monotherapy for myxedema (24). Around that time, serum protein-bound iodine (PBI) emerged as a diagnostic test and therapeutic marker; serum PBI quantitation was the only valid way to biochemically assess thyroid hormone status (25). This tool was limited in terms of treatment monitoring because the effect on serum PBI varied by agent (26). For example, l-triiodothyronine corrected BMR without much increase in serum PBI, l-thyroxine increased serum PBI sometimes to above normal, and combination l-thyroxine and l-triiodothyronine and desiccated thyroid had the advantage of normalizing serum PBI (27). In addition to BMR and serum PBI, other surrogates for treatment response included cholesterol levels, symptoms, and deep tendon reflexes, but their lack of sensitivity was always recognized (28).
Because it helps balance hormone levels, selenium can lower the risk for experiencing thyroid disorder during pregnancy (postpartum thyroiditis) and afterward. (15) Other studies have shown that when selenium deficiency is resolved through supplementation, patients experience on average 40 percent reduction in thyroid antibodies compared to a 10 percent increase when given a placebo. (16)
The thyroid gland uses iodine (mostly from foods in the diet like seafood, bread, and salt) to produce thyroid hormones. The two most important thyroid hormones are thyroxine (tetraiodothyronine or T4) and tri-iodothyronine (T3), which account for 99% and 1% of thyroid hormones present in the blood respectively. However, the hormone with the most biological activity is T3. Once released from the thyroid gland into the blood, a large amount of T4 is converted as needed into T3 - the active hormone that affects the metabolism of cells.
Alcohol consumption can wreak havoc on both thyroid hormone levels in the body and the ability of the thyroid to produce hormone. Alcohol appears to have a toxic effect on the thyroid gland and suppresses the ability of the body to use thyroid hormone. Ideally, people with hypothyroidism should cut out alcohol completely or drink in careful moderation.
