What Is Thyroid Hormone

Thyroid Stress? How Stress Causes Low Thyroid aka

Thyroid hormone is made by the thyroid gland, a butterfly-shaped endocrine gland normally located in the lower front of the neck. Thyroid hormone is released into the blood where it is carried to all the tissues in the body. It helps the body use energy, stay warm and keeps the brain, heart, muscles, and other organs working as they should.

Thyroid hormone exists in two main forms: thyroxine and triiodothyronine . T4 is the primary form of thyroid hormone circulating in the blood . To exert its effects, T4 is converted to T3 by the removal of an iodine atom this occurs mainly in the liver and in certain tissues where T3 acts, such as in the brain. T3 normally accounts for about 5% of thyroid hormone circulating in the blood.

Most thyroid hormone in the blood is bound by protein, while only a small fraction is “free” to enter tissues and have a biologic effect. Thyroid tests may measure total or free hormone levels.

Is Hashimotos Disease Dangerous Or Fatal

If left untreated, hypothyroidism can lead to some serious complications and, in rare cases, death. These include:

  • Heart problems, such as enlarged heart or heart failure.
  • Mental health issues, including depression.
  • Myxedema coma, which needs immediate emergency care. Myxedema is a rare, life-threatening condition that can lead to heart failure, seizures, coma and death.

Warning Signs Of High Cortisol And Low Thyroid

Posted by Dr. Andrew Heyman, MD on Jun 28, 2018 10:26:06 AM

When a person feels stressed, they may reach for comfort foods that contain carbohydrates and sugars and proclaim that theyre eating their feelings.

Many patients have a sense that stress, metabolism, and sugar are related to one another. They often can make the connection between eating poorly and feeling sluggish. What they may not know is that changes in diet and other lifestyle behaviors that lead to alterations in coping skills can impact cortisol, insulin, and thyroid levels, which can result in fatigue and slowed metabolism.

Receptors for all three hormones are located in nearly every cell of the body, so the relationship between them and the adrenal gland, thyroid, and pancreas is critical for energy production and balanced physiology.

When this relationship is functioning normally, people tend to feel vital and well. When they arent functioning properly, or when their function is impacted by poor rest, diet, and exercise, patients feel unwell, gain weight, and appear in your office with issues related to adrenal fatigue and thyroid problems.

Identifying Hormone Issues

Some of the initial questions youll ask when identifying issues with cortisol, insulin, and thyroid hormones include:

  • Do you have enough energy to complete daily tasks?
  • Do you sleep deeply at night?
  • Have you gained weight?

Preventing Hyperthyroidism Caused By Stress

Hyperthyroidism will undoubtedly have a specific treatment: antithyroid drugs such as propylthiouracil and methimazole. However, each patients case is different. Each patient requires a professional evaluation in order to find the most appropriate and effective treatment for them.

But beyond treatment, we need to know how to prevent these conditions. The trigger wont always be stress because autoimmune diseases exist. But because certain psychological conditions trigger metabolic changes, we must know how to handle these situations. Some keys include:

  • Limited stress over time has no effect on the thyroid. The problem is chronic stress that we dont handle, control, or face. Therefore, we must spend some time every day attending to every worry, every complex emotion, and every nuisance in our mind. Dont leave for tomorrow the shadow that bothers you today.
  • Give yourself quality time. Throughout the day, we must have at least two hours to ourselves. Physical exercise or techniques like mindfulness are very effective for dealing with stress.
  • Likewise, take care of your diet and improve your life habits. Focus on quality rest and positive social relationships.

To conclude, since stress and hyperthyroidism are related, taking care of our emotions means investing in our health. If we get up, get dressed, and shower every day, we must also remember to attend to our complex inner universe every day.

How Is Hashimotos Disease Diagnosed

How to Lose Weight with an Underactive Thyroid

First, your healthcare provider will take your medical history and perform a physical exam. He or she will feel your thyroid gland to determine if it is enlarged. Blood tests are also ordered. These include:

  • Thyroid stimulating hormone test: A high TSH level most commonly means the thyroid gland is not producing enough T4 hormone. This lab is usually most consistent with a diagnosis of hypothyroidism or subclinical hypothyroidism.
  • Free T4 test: A low T4 level suggests that the person has hypothyroidism.
  • Antithyroid antibody test: Presence of antibodies indicates a higher risk of developing Hashimotos hypothyroidism.

The most common imaging test that may be ordered is an ultrasound of your thyroid gland. The ultrasound shows the size and appearance of the thyroid and if there are any nodules or growths in your neck area.

Adrenal Stress Causes Hormonal Imbalances

Cortisol is one of the hormones released by the adrenals during the stress response. Prolonged cortisol elevations, caused by chronic stress, decrease the livers ability to clear excess estrogens from the blood. Excess estrogen increases levels of thyroid binding globulin , the proteins that thyroid hormone is attached to as its transported through the body.

When thyroid hormone is bound to TBG, it is inactive. It must be cleaved from TBG to become free-fraction before it can activate cellular receptors.

When TBG levels are high, the percentage of free thyroid hormones drops. This shows up on labs as low T3 uptake and low free T4/T3.

Aside from adrenal stress, the most common causes of elevated TBG secondary to excess estrogen are birth control pills and estrogen replacement .

Can Thyroid Problems Cause Dizziness

Thyroid hormones participate in a number of processes and functions in our body. Higher or lower production of these hormones is manifested through a wide range of symptoms. That being said, some symptoms of thyroid problems are widely discussed. For example, hair loss and weight gain/loss are often addressed, while symptoms such as dizziness do not get enough attention although its important to get informed and know as much as possible in order to manage your condition successfully. Studies on this subject are scarce, but hopefully, things will change in the near future.

If youre wondering whether thyroid problems can indeed cause lightheadedness, the answer is yes. In fact, both hypo- and hyperthyroidism can make you feel dizzy or lightheaded. How? Lets see.

What Is A T3 Test

T3 TestsT3 tests measure triiodothyronine levels in the blood. A Total T3 test measures the bound and free fractions of triiodothyronine. Hyperthyroid patients typically have an elevated Total T3 level. T3 tests can be used to support a diagnosis of hyperthyroidism and can determine the severity hyperthyroidism.

In some thyroid diseases, the proportions of T3 and T4 in the blood change and can provide diagnostic information. A pattern of increased T3 vs T4 is characteristic of Graves disease. On the other hand, medications like steroids and amiodarone, and severe illness can decrease the amount of thyroid hormone the body converts from T4 to T3 resulting in a lower proportion of T3.

T3 levels fall late in the course of hypothyroidism and therefore are not routinely used to evaluate patients with underactive or surgically absent thyroid glands.

Measurement of Free T3 is possible, but is often not reliable and therefore may not be helpful.

Ways That Stress Causes Hypothyroid Symptoms

Causes of Stress

This article is part of a special report on Thyroid Disorders. To see the other articles in this series, .

Weve already talked about how blood sugar imbalances and poor gut health can lead to hypothyroidism and Hashimotos. The harmful effects of adrenal stress complete the triad.

The adrenals are two walnut-shaped glands that sit atop the kidneys. They secrete hormones such as cortisol, epinephrine and norepinephrine that regulate the stress response. But these hormones play other crucial roles, many of which are directly related to thyroid health. In fact, as well see in this article, proper thyroid function depends on healthy adrenal glands.

Most people are aware of the obvious forms of stress that affect the adrenal glands: impossibly full schedules, driving in traffic, financial problems, arguments with a spouse, losing a job and the many other emotional and psychological challenges of modern life.

But other factors not commonly considered when people think of stress place just as much of a burden on the adrenal glands. These include blood sugar swings, gut dysfunction, food intolerances , chronic infections, environmental toxins, autoimmune problems and inflammation. All of these conditions sound the alarm bells and cause the adrenals to pump out more stress hormones. In this context, stress is broadly defined as anything that disturbs the bodys natural balance .

But some of the more common symptoms are:

Adrenal Stress Reduces Conversion Of T4 To T3

We discussed under-conversion of T4 to T3 in a prior article. Remember that although 93% of the hormone produced by the thyroid gland is T4, it is inactive in that form and must be converted into T3 before it can be used by the cells. The inflammatory cytokines I listed above not only disrupt the HPA axis, they also interfere with the conversion of T4 to T3.

The enzyme 5-deiodinase catalyzes the conversion of T4 into T3 in peripheral tissues such as the liver and the gut. Both Th1 and Th2 inflammatory cytokines IL-6, TNF-alpha, IFN-gamma and IL-1 beta have been shown to suppress the conversion of T4 to T3. In patients without thyroid illness, as levels of IL-6 rise, levels of serum T3 fall. And injections of inflammatory cytokines into healthy human subjects resulted in a rapid reduction of serum T3 and TSH levels, and an increase in the inactive reverse T3 form, while T4 and free T4 levels were only minimally changed.

Thyroid Disease & Anxiety

If youre feeling completely overwhelmed and always anxious, its time to get your thyroid checked. As a Functional Medicine Practitioner, one of the first tests I run when someone tells me they deal with chronic anxiety is a complete thyroid panel.

Having excess thyroid hormone such as in the case of Graves disease can also cause anxiety. What many people dont know is that this can also occur with Hashimotos.

When dealing with Hashimotos Thyroiditis, your immune system is attacking the thyroid gland. When your thyroid gland is under attack, thyroid hormones can spill over into the bloodstream triggering anxiety and even heart palpitations.

Its also important to understand that every single cell in the body has receptors for thyroid hormones, and without proper thyroid function many systems in your body suffer. Not only that, but thyroid hormones act directly on the brain among many other body systems which makes sense as to how it can affect anxiety levels.

What Causes Hashimotos Disease

Hashimotos disease is an autoimmune disease, which means the bodys immune system is attacking its own cells and organs. Normally, the immune system protects the body against infections caused by bacteria, viruses and other harmful substances.

In Hashimotos disease, the immune system makes antibodies that attack and damage the thyroid tissue. As a result, the thyroid gland becomes inflamed and the ability to make thyroid hormone becomes damaged, eventually leading to hypothyroidism.

What Is Hashimoto’s Thyroiditis

How to Treat and Cure Hypothyroidism: Top 10 Home Remedies ...

Hashimoto’s thyroiditis is an autoimmune disorder, which means it occurs when immune cells attack healthy tissue instead of protecting it. In Hashimoto’s thyroiditis, immune cells mistakenly attack the healthy thyroid tissue, causing inflammation of the thyroid.

The thyroid is a small gland located at the base of your neck that produces two hormonesâone, thyroxine , and the other, triiodothyronine . These two hormones stimulate the metabolism of almost every tissue in the bodyâheart, brain, muscles, and other organs.

The pituitary gland in the brain regulates thyroid-stimulating hormone , which triggers the production of T4 and T3. When thyroid hormone levels in your body are low, the pituitary gland makes more TSH. Elevated TSH may signify that the body isn’t producing enough thyroid hormones, indicative of hypothyroidism.

You will develop hypothyroidism if Hashimoto’s attacks your thyroid to the point that the gland can no longer produce enough thyroid hormones for your body to function correctly.

Hypothyroidism is the condition in which your thyroid hormone production drops, causing virtually all of your body processes to slow down and change. This condition can feel like being stuck in second gearâeverything slows down.

Common symptoms of hypothyroidism include:

  • Tiredness, sluggishness

What Are The Main Kinds Of Thyroid Conditions

There are two main kinds of thyroid conditions:

  • Hyperthyroidism . This is when the thyroid is overactive and makes too much thyroid hormone. This condition can cause many of your bodys functions to speed up. Hyperthyroidism during pregnancy usually is caused by an autoimmune disorder called Graves disease. Autoimmune disorders are health conditions that happen when antibodies attack healthy tissue by mistake. If you have Graves disease, your immune system makes antibodies that cause your thyroid to make too much thyroid hormone. In rare cases, hyperthyroidism is linked to a severe form of morning sickness called hyperemesis gravidarum . Also in rare cases, hyperthyroidism can be caused by thyroid nodules. These are lumps in your thyroid that make too much thyroid hormone.
  • Hypothyroidism . This is when the thyroid is underactive and doesnt make enough thyroid hormones, so many of your bodys functions slow down. Hypothyroidism during pregnancy usually is caused by an autoimmune disorder called Hashimotos disease. When you have Hashimotos disease, your immune system makes antibodies that attack your thyroid and damage it so it cant produce thyroid hormones.
  • If you have a thyroid condition during pregnancy, treatment can help you have a healthy pregnancy and a healthy baby.

    How Is Hashimotos Disease Treated

    If Hashimotos disease does progress to hypothyroidism, usual treatment is a synthetic form of thyroid hormone called levothyroxine .

    This drug restores the normal function of the thyroid. Youll need to take it every day for the rest of your life. Your providers and you will figure out how to adjust your dose to make sure that your hypothyroidism is kept under control.

    What Causes Hyperthyroidism

    In more than 70% of cases, hyperthyroidism is caused by Graves disease. Normally, the immune system helps protect your body against viruses, bacteria, and other substances. An autoimmune disease causes it to attack your bodys tissues and/or organs. With Graves disease, the immune system stimulates your thyroid, making it produce too much hormone. Doctors think Graves disease may run in families. It is most common among young women.

    Two other common causes for hyperthyroidism are:

    • Hyperfunctioning thyroid nodules. One or more nodules or lumps in the thyroid grow. This increases the production of the thyroid hormone.
    • A problem with the immune system or a viral infection causes the thyroid gland to become inflamed. This causes extra thyroid hormone to leak into your bloodstream. Thyroiditis could lead to hypothyroidism over time.

    Consuming foods or medicines that contain high levels of iodine can lead to hyperthyroidism. In rare cases, the cause could be a benign tumor on the pituitary gland.

    Get Smart About Sleep

    3 Easy Ways to Help Thyroid Work Correctly

    You might feel run down, even if youâre taking medication. Yet all too often, âpeople with hypothyroidism donât get enough sleep, or the sleep theyâre getting isnât good quality,â Hatipoglu says.

    To ensure your body has a chance to rest and recover:

    Aim for 8 hours of sleep every night. Thatâs actual sleep, not just time spent in bed. Hit the hay and wake up at roughly the same times most days.

    âA regular sleep schedule makes it easier to fall and stay asleep,â says Shelby Harris, PsyD, director of the behavioral sleep medicine program at Montefiore Medical Center in New York.

    Your bedroom should be dark, quiet, and cool. Keep pets out of your bed, and if possible, out of your room. That way, they wonât disrupt your sleep.

    Try a wind-down routine. At least 30 minutes before bed, do something relaxing. Harris suggests a cup of herbal tea, a shower, or reading in a low-lit room.

    If all else fails, talk with your doctor. If you snore, canât fall or stay asleep, or are worn out even if you do get 8 hours of shut-eye, you may have a sleep disorder. Your doctor might send you to a sleep specialist.

    Definition: What Do The Following Patients Over The Age Of 60 Years Have In Common

  • A 72 year old woman with fluttering of the heart and vague chest discomfort on climbing stairs
  • An 80 year old man with severe constipation who falls asleep often
  • A 65 year old woman who has lost strength in her legs, causing difficulty in climbing stairs she has recently lost 15 lbs in spite of a very good appetite
  • A 75 year old woman who has developed difficulty swallowing and a dry cough, accompanied by hoarseness, weight gain, and dry, itchy skin
  • A 78 year old man with hearing loss
  • An 84 year old woman in whom a hand tremor has caused her to give up favorite activities. She is so depressed that she will not eat, and she has lost 12 lbs in the last 4 months.
  • All of these patients have abnormal function of their thyroid glands. Patients 1, 3 and 6 have hyperthyroidism, that is, excessive production of thyroid hormone by their thyroid glands. Patients 2, 4 and 5 have hypothyroidism, or reduced production of thyroid hormone. While some of the symptoms of hyperthyroidism and hypothyroidism are similar to those in younger patients, it is not uncommon for both hyperthyroidism and hypothyroidism to be manifest in subtle ways in older patients, often masquerading as diseases of the bowel or heart or a disorder of the nervous system. An important clue to the presence of thyroid disease in an elderly patient is a history of thyroid disease in another close family member such as a brother, sister or child of the patient.
