What Causes The Thyroid To Be Low

What Common Symptoms Can Happen With Thyroid Disease

5 Causes of a LOW TSH – Why a low TSH isn’t always hyperthyroidism

There are a variety of symptoms you could experience if you have a thyroid disease. Unfortunately, symptoms of a thyroid condition are often very similar to the signs of other medical conditions and stages of life. This can make it difficult to know if your symptoms are related to a thyroid issue or something else entirely.

For the most part, the symptoms of thyroid disease can be divided into two groups those related to having too much thyroid hormone and those related to having too little thyroid hormone .

Symptoms of an overactive thyroid can include:

  • Experiencing anxiety, irritability and nervousness.
  • Having trouble sleeping.
  • Experiencing an intolerance to cold temperatures.

Inflammation Of The Thyroid Gland

Hypothyroidism often results from previous or currently ongoing inflammation of the thyroid gland, which leaves a large percentage of the cells of the thyroid damaged and incapable of producing sufficient hormone.

The most common cause of thyroid gland failure is called autoimmune thyroiditis , a form of thyroid inflammation caused by the persons own immune system.

Who Should Be Screened For Hypothyroidism

  • All children who fail the thyroid portion of their newborn screening
  • All children with poor linear growth
  • All children who have had cranial irradiation as part of medical treatment for cancer
  • All children with a history of severe brain injury or abnormal development
  • Anyone with symptoms of hypothyroidism
  • All pregnant women with a family history or symptoms of thyroid disease

Treatments For Low Tsh Levels

In many cases, doctors use radioactive iodine as a treatment for hyperthyroidism. This treatment destroys the thyroid gland over time, creating a life-long need for thyroid hormone medication. Antithyroid medication such as methimazole decreases the amount of thyroid hormone produced but is not a long-term solution.

Doctors also sometimes see the need to remove all or part of the thyroid gland, depending on the condition’s severity. Doctors discuss your treatment options with you and decide which is right based on your preferences or needs.

What Is The Normal Range Of Tsh

What Causes Thyroiditis?

There are a range of levels that your TSH levels can be. Learning what these levels mean will help you work with your doctor to address your condition adequately.

  • Normal TSH â Adults should have TSH hormone levels that range from 0.4-4.2 mU/L. This indicates that the signals from your pituitary gland match the activity of your thyroid gland. Your doctor will use this hormone level alongside the other signals and side affects you may be showing to determine if there is an underlying health issue at hand.
  • Low TSH â Low TSH levels can be a sign that you are dealing with an overactive thyroid gland from conditions such as goiter, noncancerous tumors or Gravesâs disease. The thyroid may also become overactive during the first trimester of pregnancy. If you are already being treated for thyroid issues, you may develop low TSH levels if you are taking too much thyroid medication. If you are not showing signs of overactive thyroid, you may have damaged the pituitary gland, causing it to produce less TSH.
  • High TSH â High levels of TSH are typically caused by an underactive thyroid or hypothyroidism. This is typically caused by Hashimotoâs thyroiditis. If you are already being treated for a thyroid disorder this can be a sign that you need to increase your medication. In rare cases, you may be showing high than normal TSH levels because you have developed a tumor that is causing the pituitary gland to over-produce TSH.

Can Hypothyroidism Be Prevented

Hypothyroidism cannot be prevented. The best way to prevent developing a serious form of the condition or having the symptoms impact your life in a serious way is to watch for signs of hypothyroidism. If you experience any of the symptoms of hypothyroidism, the best thing to do is talk to your healthcare provider. Hypothyroidism is very manageable if you catch it early and begin treatment.

How Can I Help My Child

If your child has hypothyroidism, it’s very important to give the thyroid hormone as instructed by your doctor.

If your child is too young to chew or swallow the pill, crush it and mix it with a small amount of water, non-soy baby formula, or breast milk. Make sure your child drinks all the liquid. Some thyroid hormone pills dissolve more easily in liquids than others, so talk to your doctor if you’re having trouble with this.

Some infant formulas , medicines, and mineral supplements may block the thyroid medicine from being absorbed. Check with your doctor about how and when to give other medicines or supplements while your child takes thyroid hormone.

Why Your Thyroid Hormone Levels May Be Fluctuating

If you have thyroid disease, you may experience some fluctuations in your thyroid hormone levels from time to time. These fluctuations can occur as your thyroid disease progresses.

But other factors, such as hormonal changes and medication variations, can alter your thyroid hormone levels as well. These hormonal fluctuations can produce a variety of symptoms.

This article explains what things might contribute to thyroid hormone fluctuations and what you can do about it.

    Lab Testing For Your Thyroid

    Looking at your thyroid gland via imaging doesn’t usually give you any information about the FUNCTION of the thyroid gland.

    The function of your thyroid gland is very important because it relates to how well your thyroid is able to produce thyroid hormone.

    Any change to the ability of your gland to produce thyroid hormone will result in very specific symptoms that are too big to be ignored and these symptoms will often drive people into the Doctors office for evaluation.

    Fortunately, many conditions that result in thyroid gland enlargement usually do not interfere with thyroid hormone production.

    Some conditions, such as Hashimoto’s thyroiditis, cause both thyroid gland enlargement AND thyroid hormone issues.

    Because of this each and every patient with a known or suspected thyroid gland issue should undergo thyroid function testing with blood tests.

    To test your thyroid function you will need the following tests:

    • TSH – This will help you understand if your brain is talking to your thyroid gland.
    • Free T3 – This is the most important thyroid hormone in your body and is responsible for the majority of thyroid cellular activity/
    • Free T4 – This is the most abundant thyroid hormone in your body and is important because it acts as a reservoir for T3 thyroid hormone.
    • Thyroid Antibodies – The presence or absence of thyroid antibodies can help you understand if you have an autoimmune disease or if your body is attacking your own thyroid gland.

    High Tsh But Normal Free T4

    What does it mean if your TSH levels are too high but you have normal FT4?

    The journal American Family Physician says that levels of TSH over 4.0 mIU/L and free T4 levels within the normal range could be an indicator of subclinical hypothyroidism. This means that a person is at risk of developing hypothyroidism but is not yet showing any noticeable symptoms.12

    Potential Complications Of Hypothyroidism

    Left untreated, the symptoms of hypothyroidism will usually progress. That can lead to complications including birth defects, infertility, elevated bad cholesterol, and mental health problems. Rarely, complications from untreated hypothyroidism can result in severe life-threatening depression, heart failure, or a type of coma called myxedema coma.

    Additionally, because the body is expecting a certain amount of thyroid hormone, the pituitary will make additional thyroid stimulating hormone as a way to prompt the thyroid to produce more hormone . This extra work at signaling the thyroid gland to keep producing T4 may cause the thyroid gland to become enlarged, leading to the formation of a goiter .

    7 Causes Behind Low Thyroid Function

    A high TSH in people who are not undergoing thyroid disease treatment usually indicates the presence of primary hypothyroidism.

    This is by far the most common form of hypothyroidism, and it occurs because the thyroid gland produces an inadequate amount of thyroid hormones. The pituitary gland senses these low levels and increases the production of TSH.

    An elevated TSH may also occur with normal thyroid function due to the presence of antibodies, proteins made by the immune system.

    Besides medications, the treatment for hair loss can also include a hair transplant. In this procedure, small pieces of the scalp containing hair follicles are transferred to the bald areas. The surgery can be risky because it involves the usual risks of surgery, including shock and pain. Furthermore, it is expensive and is often not covered by insurance. But if you dont want to live with a bald area thats affecting your confidence and your appearance, hair transplant surgery may be the right option.

    If the baldness is caused by a fungal infection, you can consider undergoing a hair transplant. In this procedure, tiny pieces of scalp are removed and moved to the bald spots. Despite the risks, this procedure is highly effective and is often covered by health insurance plans. A hair transplant can cost thousands of dollars, and you will most likely need to pay a large part of it out of pocket. The only downside to hair transplant surgery is the high cost.

    Although alopecia is an embarrassing problem for many people, it can also be caused by trauma. People who undergo painful procedures on their hair may be at risk for traumatizing alopecia. This condition often results in thinning or falling hair. In some cases, the scalp becomes red and the scalp can even become inflamed. Antibiotics and antimalarial drugs may also be prescribed to help treat this disorder.

    What Causes Hypothyroidism In Men

    The causes of hypothyroidism in women and men are similar. As just mentioned, in the U.S., the main cause of hypothyroidism is an autoimmune disease called Hashimotos thyroiditis. In this condition, your immune system makes cells that attack your thyroid gland, which keeps it from working properly.

    Other causes of hypothyroidism include:

    • Cancer, such as thyroid cancer

    • Previous radiation or surgery to the thyroid or other parts of the neck

    • Some medications

    • Not getting enough iodine in your diet

    What Causes Thyroid Disease

    The two main types of thyroid disease are hypothyroidism and hyperthyroidism. Both conditions can be caused by other diseases that impact the way the thyroid gland works.

    Conditions that can cause hypothyroidism include:

    • Thyroiditis: This condition is an inflammation of the thyroid gland. Thyroiditis can lower the amount of hormones your thyroid produces.
    • Hashimotos thyroiditis: A painless disease, Hashimotos thyroiditis is an autoimmune condition where the bodys cells attack and damage the thyroid. This is an inherited condition.
    • Postpartum thyroiditis: This condition occurs in 5% to 9% of women after childbirth. Its usually a temporary condition.
    • Iodine deficiency: Iodine is used by the thyroid to produce hormones. An iodine deficiency is an issue that affects several million people around the world..
    • A non-functioning thyroid gland: Sometimes, the thyroid gland doesnt work correctly from birth. This affects about 1 in 4,000 newborns. If left untreated, the child could have both physical and mental issues in the future. All newborns are given a screening blood test in the hospital to check their thyroid function.

    Conditions that can cause hyperthyroidism include:

    An underactive thyroid is when your thyroid gland doesn’t produce enough of the hormone thyroxine .

    Most cases of an underactive thyroid are caused by the immune system attacking the thyroid gland and damaging it, or by damage that occurs as a result of treatments for thyroid cancer or an overactive thyroid.

    What You Should Do When The Levels Are Low

    When your TSH levels are low, it is vital to consult your doctor to find the underlying cause of the abnormality. For there, your doctor will prescribe the appropriate medication and other recommendations, which includes the following:

    • Medications

    Doctors will typically prescribe an anti-thyroid drug to increase your levels caused by hyperthyroidism. Depending on the severity of your condition, surgery may be necessary. This type of surgical procedure has a high chance of success for complete recovery.

    For patients with hypothyroidism, your doctor may prescribe hormone replacement therapy to boost your TSH level.

    • Diet Changes

    A dietary change is essential to increase your TSH. The most valuable minerals for hyperthyroidism are selenium and iodine. You have to include foods that are rich in these two minerals. The common sources of iodine are sea vegetables, cranberries, and yogurt. For examples of selenium-rich foods, you can eat beef liver, chicken, halibut, and Brazil nuts.

    In addition, a low TSH can also be a result of abnormal blood sugar levels. Your doctor will prescribe a medication to balance this abnormality. You also have to follow a diet plan that will help regulate your blood sugar levels.

    • Supplements
    • Exercise

    Low And High Tsh Levels

    Because the normal values differ depending on your age, the high and low result will also vary depending on which category you belong. In general, when the TSH level is above the normal range, your TSH level is high. If it is below the normal range, the TSH level is low.

    For example, an average adult has a normal TSH level ranging from 0.4 4.2 mIU/L. If the result is more than 4.2 mIU/L, the TSH level is high. A low TSH result will have a TSH level that is below 0.4 mIU/L.

    Associated Symptoms Of Thyroid Gland Disorders

    A study6 conducted by the Mansoura University Hospitals in Egypt found that dysfunctions affecting the Thyroid gland can manifest symptoms quite similar to those found in menopause.

    For this reason, it is vital for medical experts to look at the Thyroid gland as a possible contributing factors to symptoms when a woman is going through menopause, and not to immediately prescribe her estrogen replacement therapy medication as a solution to her symptoms.

    The study was conducted among a group of 360 women. The study found that 11.1% of the women suffered from Thyroid disorders and the administration of appropriate treatment to assist with regulating Thyroid function yielded positive results in regards to their symptoms.

    Determining associated symptoms of Thyroid gland disorders, and looking for these particular symptoms when hot flashes are experienced, will help the treatment options provided to a patient suffering from hot flashes be more appropriate and work faster.

    How Do Doctors Diagnose Hypothyroidism

    Thyroid Supplements

    Your doctor will take your medical history and perform a physical exam. A hypothyroidism diagnosis cant be based on symptoms alone because many of its symptoms are the same as those of other diseases.1 Thats why your doctor may use several thyroid blood tests and imaging tests to confirm the diagnosis and find its cause.

    Because hypothyroidism can cause fertility problems, women who have trouble getting pregnant often get tested for thyroid problems.

    What Is T3 And Free T3

    The thyroid hormone triiodothyronine is referred to as T3 because it contains one less iodine molecule than T4. Dr. Irizarry explains that thyroxine converts to triiodothyronine when it reaches the cells in the body. T3 is 4 times more active than the more abundant T4.3

    As with FT4, free T3 is the active level of thyroid hormone that can be used by the body.

    What Are The Signs And Symptoms Of Hypothyroidism

    The signs and symptoms of hypothyroidism vary from person to person. The severity of the condition also affects which signs and symptoms appear and when. The symptoms are also sometimes difficult to identify.

    Early symptoms can include weight gain and fatigue. Both become more common as you age, regardless of your thyroids health. You may not realize that these changes are related to your thyroid until more symptoms appear.

    The most common signs and symptoms of hypothyroidism include:

    For most people, symptoms of the condition progress gradually over many years. As the thyroid slows more and more, the symptoms may become more easily identified. Of course, many of these symptoms also become more common with age in general.

    If you suspect your symptoms are the result of a thyroid problem, talk with your doctor. They can order a blood test to determine if you have hypothyroidism. Learn more about the signs and symptoms of hypothyroidism.
