What Are The Symptoms Of Elevated Thyroid Levels

Possible Causes Of Hypothyroidism

High TSH Symptoms (The complete list what’s a normal level)

There is no one cause of hypothyroidism, nor isthere always a direct linear path between one of the precipitating events andits onset. However, it is important to know the potential causes so that youcan connect the dots with possible symptoms.

Major causes of hypothyroidism include:

  • Hashimotos thyroiditis. This autoimmune disease produces antibodies that attack the tissues of the thyroid, causing it to produce less thyroid hormone.
  • Medication. Certain medications, including lithium, can lower thyroid hormone production.
  • Hyperthyroidism treatment. A number of treatments for hyperthyroidism, including radioactive iodine treatment, can impair thyroid function.
  • Radiation therapy. Radiation therapy for conditions unrelated to the thyroid may cause the thyroid to shrink.

There are a few other possible causes, includingiodine disorders and some pregnancy-related risks. Well take a look at thedangers of the latter just below. But it is important to know that if you fallinto any of these risk categories, the seemingly-mild symptoms might be so muchmore.

High Tsh In Pregnancy

It is normal during pregnancy for T4 levels to increase which causes TSH levels to drop. According to Dr. Sandra Fryhofer on Medscape, T3 and T4 thyroid hormones can increase by up to 50% during pregnancy. Even though some labs put the normal TSH range for pregnancy as high as 5 mIU/L, Dr. Fryhofer recommends a much lower level.

The recommendations for TSH during pregnancy are as follows:

  • First trimester: 0.1 2.5 mIU/L
  • Second trimester: 0.2 3.0 mIU/L
  • Third trimester: 0.3 3.0 mIU/L

If TSH levels are higher than 2.5 mIU/L during pregnancy, Dr. Fryhofer recommends testing for levels of T4 to check for hypothyroidism in pregnancy.

Questions To Ask Your Doctor

  • What is the cause of my hyperthyroidism?
  • Do I have Graves disease?
  • What types of food and medicine contain high levels of iodine?
  • What is the best treatment?
  • Will I need to take medicine? If so, for how long and what are the side effects?
  • Will I need surgery? If so, what are the benefits and risks?
  • Are there any lifestyle changes I can make to relieve my symptoms?
  • Am I at risk for related health problems?

Milder Forms Of Hypothyroidism Are Harder To Diagnose

Although the majority of cases of hypothyroidism will be easy to diagnose with these simple blood tests, many millions of people will have this disease in mild to moderate forms which are more difficult to diagnose. The solution for these patients is more complex and this is due to several factors.

First, we must realize that not all people with hypothyroidism are the same. There are many degrees of this disorder from very severe to very mild. Additionally, and very importantly, we cannot always predict just how bad an individual patient will feel just by examining his or her thyroid hormone levels. Blood levels have normal ranges, but other factors need to be taken into account as well, such as the presence or absence of symptoms.

In other words, some patients with what would be considered mild deviations in their thyroid laboratory test results will feel just fine while others will be quite symptomatic. The degree of thyroid hormone abnormalities often, but NOT ALWAYS, will correlate with the degree of symptoms.

It is important for both you and your physician to keep this in mind since the goal is not necessarily to make the lab tests go into the normal range, but to make you feel better as well! We must also keep in mind that even the normal thyroid hormone levels in the blood have a fairly large range, so even if a patient is in the normal range for the general population, it may not be the normal level for them.

Avoid Generics Or Get A Stable Multiple

Hyperthyroidism is characterized by hypermetabolism and ...

Some HMOs and insurance companies will automatically override your healthcare provider’s requested brand and supply you with a generic levothyroxine made by one of many different manufacturers.

There is nothing inherently wrong with generic drugs. The problem with this practice, however, is that you may be switched from one generic brand to the next every month without even knowing it. And, each time you are, you may receive a product that has a slightly different potency or is closer to the expiration date that you might otherwise prefer.

To ensure medication consistency, ask your healthcare provider to write “no generic substitution” or “DAW” on the prescription. If your insurer threatens a higher drug copay, ask your healthcare provider to write a motivation outlining why the specific brand is necessary.

If your insurer denies your request, try asking healthcare provider to write a prescription for a six-month drug supply. Once received, check to ensure the drugs are all from the same manufacturer and are within the expiration date for at least the next six months.

Diagnosing High Tsh Levels

When you see your doctor, the most common test for a high TSH level is a blood test. They will not only check your TSH level, but they also are looking at your triiodothyronine and thyroxine levels.

Imaging tests such as an ultrasound or a thyroid scan with a special camera and slightly radioactive iodine are used to look at your thyroid. It looks for inflammation or shrinkage, which can both occur with hypothyroidism. Another test, called a radioactive iodine uptake test, is done to see if your thyroid is taking up enough iodine to make the hormones it produces.

Thyroid antibody tests can be used to diagnose autoimmune thyroid disorders, like Hashimotos disease.

To Treat Or Not To Treat

Aging WellVol. 5 No. 6 P. 6

Physicians are accustomed to checking thyroid-stimulating hormone in older adults with symptoms of an over- or underactive thyroid, as its a fairly accurate and routine measure of thyroid function. But a new study suggests that for many patients, treatment for mild TSH elevations may no longer be warranted.

As increasing numbers of people live into their 80s and 90s, it is important to know how to manage their health, including thyroid function, says Anne Cappola, MD, ScM, an associate professor of medicine at the Perelman School of Medicine at the University of Pennsylvania and lead study author. We sought to describe what happens to thyroid function in older people over time and to determine the relationship between thyroid function and mortality in this population.

The study, accepted for publication in The Endocrine Societys Journal of Clinical Endocrinology & Metabolism, questions the assertion that slightly elevated TSH levels are linked to an increase in mortality and suggests that such elevations may actually be a normal part of healthful aging.

Study Particulars The study first examined 5,888 men and women aged 65 and older between 1989 and 1992. Then in 2005, researchers reexamined 843 surviving participants thyroid function for any changes in physical and cognitive function. Study participants ranged in age from 77 to 102, with a mean age of 85.

So How Do Doctors Use Tsh

TSH is primarily used as a marker of thyroid hormone status in the entire body.

Checking your TSH can be used as a quick measure to determine if your thyroid is functioning properly or not.

A high TSH tells your Doctor that your thyroid is not working properly which means that you may need the use of thyroid hormone medications to increase and normalize thyroid function.

After starting thyroid medication the TSH can be used to “track” your progress.

As you take thyroid medication your TSH should be reduced back to the “normal” range.

As this occurs you are said to once again become “euthyroid”.

This is how everything is supposed to work, but is it really that easy?

This is where Doctors and patients tend to disagree .

Even though you can “normalize” the TSH with thyroid medications, many of the symptoms of hypothyroidism may actually still persist.

We will discuss more of that below, but for now, let’s discuss what kind of symptoms you may experience if your TSH is elevated.

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

When Should I See My Healthcare Provider

If youre experiencing signs and symptoms of hyperthyroidism, its important to see your healthcare provider so they can assess your condition and recommend treatment.

If youve already been diagnosed with hyperthyroidism, youll likely need to see your provider regularly to make sure your treatment is working.

If youre experiencing signs of thyroid storm, a complication of hyperthyroidism, such as a high fever and a very fast heart rate, get to the nearest hospital as soon as possible.

Supporting A Healthy Thyroid

Now that you have a basic overview of thyroid function, you may be wondering if there are ways to support your thyroid health in addition to medication. This is important because sometimes it can take a while before medication can correct hormone imbalance. In this case, the next best thing you can do is adjust your lifestyle habits.Managing stress: Because there is a relationship between your adrenal health and your thyroid health, its wise to get a hold on your stress levels. When you are chronically stressed, adrenal fatigue an overtaxing of the adrenal system may kick in, triggering your body to release hormones as a way of coping. This chronic stress can worsen thyroid issues, leading to imbalanced hormone levels. Chronically stressed? You might notice slowed metabolism and weight gain and stress may even further lower your levels of T3 and T4. It can also affect the conversion of T4 into T3.For this reason, its key to find a regular stress management ritual. This might be a daily yoga, meditation, or journaling break in which you disconnect from all distractions and stressors and simply focus on your breath and your emotional well-being. Regular nature walks also referred to as earthing or forest bathing have been proven to provide stress reduction on a physiological level as well.

Subclinical Hypothyroidism And Infertility

The thyroid hormones T3 and T4 play a key role in reproductive health, and thyroid dysfunction is a common cause of infertility. For this reason, Shah explains, you might consider treatment of a TSH level of under 4.5 mlU/L if you are trying to get pregnant or are experiencing infertility .

The American Thyroid Association recommends that women of childbearing age with TSH levels between 2.5 and 10 be tested for thyroperoxidase antibodies, which are common in individuals with hypothyroidism and are an indicator of autoimmune thyroid disease.

If TPO antibodies are positive, treatment should be considered even if the TSH level is between 2.5 and 4.0, which would typically be considered normal.

If no TPO antibodies are found, whether or not to seek treatment may come down to other health and risk factors. Its important to work closely with a reproductive endocrinologist to make the best decisions for you.

The good news is, research has shown that treating hypothyroidism often effectively treats infertility. In a study in the International Journal of Applied & Basic Medical Research, among women with infertility and elevated TSH levels, more than three-quarters were able to get pregnant within a year after starting hypothyroid treatment.

Where Can I Find Support

Why Thyroid Levels Fluctuate....

Hyperthyroidism impacts you physically, psychologically, and emotionally. Its critical that you have a strong network of people you trust and can turn to for support.

It starts with your family. Since thyroid disease runs in families, being honest and open with your relatives is the best policy, as you might be alerting them to a problem they didnt even know to look out for.

To help you build your own support network outside of those closest to you, check out the GDATFs community resources to find a support group .

In addition, you may find these resources helpful:

  • ThyroidChange. If you want to join a community that pushes for personalized care and support for patients with thyroid disease, look no further. You can also use their website to learn more about thyroid disease and its treatments, find a doctor based on specific criteria and patient recommendations, or schedule a telemedicine appointment with a doctor for your thyroid care.
  • The American Association of Endocrine Surgeons . Since finding a high-volume, experienced surgeon is critically important when choosing a thyroidectomy to treat your hyperthyroidism, this organization makes it easy with its Surgeon Finder tool.

Causes Incidence And Risk Factors:

The thyroid gland is an important organ of the endocrine system, located in the front of the neck just below the voicebox. The thyroid secretes the hormones thyroxine , triiodothyronine , and calcitonin, which control body metabolism and regulate calcium balance. The secretion of T3 and T4 by the thyroid is controlled by an endocrine feedback system involving the pituitary gland and the hypothalamus . Lowered levels of these thyroid hormones result in increased levels of pituitary and hypothalamic hormones. The reverse is also true — when levels of the thyroid hormones rise, pituitary and hypothalamic hormones fall back. This helps keep levels appropriately balanced.

Since the thyroid gland is regulated by the pituitary gland and the hypothalamus, thyroid disorders may result not only from defects in the thyroid itself but also from the disruption of the control system in these other organs. Thyroid disorders caused by overproduction of thyroid hormones are called hyperthyroidism, and underproduction of these hormones is known as hypothyroidism.

Risk factors for secondary hypothyroidism include being over 50 years old, being female, and having a history of pituitary or hypothalamic dysfunction.

How Long Will It Take For Symptoms To Improve

Some patients will notice a slight reduction in symptoms within 1 to 2 weeks, but the full metabolic response to thyroid hormone therapy is often delayed for a month or two before the person feels completely normal. It is important that the correct amount of thyroid hormone is used. Not enough and the patient may have continued fatigue or some of the other symptoms of hypothyroidism.

Too high a dose could cause symptoms such as nervousness, palpitations, or insomnia, which are typical of hyperthyroidism . Some recent studies have suggested that too much thyroid hormone may also cause increased calcium loss from bone, increasing the risk of osteoporosis.

For people with heart conditions or heart disease, an optimal thyroid dose is particularly important. Even a slight excess may increase the risk for heart attack or worsen angina. Some physicians feel that more frequent dose checks and blood hormone levels are appropriate in these patients.After about one month of treatment, hormone levels are measured in the blood to establish whether the dose of thyroid hormone which the patient is taking is appropriate. Often blood samples are also checked to see if there are antibodies against the thyroid, a sign of autoimmune thyroiditis.

What Is The Thyroid

The thyroid is a small gland below the skin and muscles at the front of the neck, at the spot where a bow tie would rest.

It’s brownish red, with left and right halves that look like a butterfly’s wings. It weighs less than an ounce, but helps the body do many things, such as get energy from food, grow, and go through sexual development.

Treatments For An Overactive Thyroid

Symptoms of High TSH

An overactive thyroid is usually treatable.

The main treatments are:

  • medicine that stops your thyroid producing too much of the thyroid hormones
  • radioiodine treatment where a type of radiotherapy is used to destroy cells in the thyroid, reducing its ability to produce thyroid hormones
  • surgery to remove some or all of your thyroid, so that it no longer produces thyroid hormones

Each of these treatments has benefits and drawbacks. You’ll usually see a specialist in hormonal conditions to discuss which treatment is best for you.

What Is The Thyroid Gland

The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. The thyroids job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body. Thyroid hormone helps the body use energy, stay warm and keep the brain, heart, muscles, and other organs working as they should.

High Tsh: Causes Symptoms And How It Affects T3 And T4

Jenny Hills, Nutritionist and Medical Writer Health

High level of TSH usually indicates that you have an underactive thyroid and that it doesnt produce enough thyroid hormones. Thyroid-stimulating hormone directly affects how much T3 and T4 hormones the thyroid secretes. If there is not enough T3 and T4 in the blood, your pituitary gland will increase levels of TSH as a result. Elevated TSH levels usually cause symptoms of hypothyroidism like fatigue, constipation, joint pain, a puffy face, or heavy menstrual bleeding .

The reasons for levels of TSH being higher than the normal range can include dysfunction of your thyroid, an autoimmune disease, or a side effect of some medications. Sometimes pregnancy can cause T3 and T4 to increase which will affect levels of TSH. If you are showing signs of an underactive thyroid and your TSH levels are too high, doctors will usually arrange for blood tests to check for levels of free T3 and T4.

To treat symptoms of high TSH, doctors usually prescribe thyroxine to lower TSH levels and treat hypothyroidism. Blood tests are then regularly taken to monitor levels of TSH and regulate thyroid therapy.

In this article, you will find out about the important role thyroid hormones play in your general health. I will also examine what medical literature says about how high TSH levels affect the thyroid hormones T3 and T4 . This will help you to spot the signs and symptoms of an underactive thyroid.
