What Should My Thyroid Levels Be

What Does It Mean When Your Tsh Is Low

How high should my T3 be?

Low levels typically indicates an overractive thyroid gland, which produces too much thyroid hormone. This is known medically as hyperthyroidism.

It can be caused by an autoimmune disease , goiter, excessive iodine in the body, or an overdose of synthetic thyroid hormone.

Initial hyperthyroidism treatment can involve antithyroid medications and radioactive iodine to slow down thyroid hormone production. Most respond well to hyperthyroidism medications and are treated successfully.

Summary: Low TSH levels for the average adult are less than 0.2 mIU/L. This reading typically indicates an overractive thyroid.

How Was The Study Done

A hefty study group of 2,856 individuals aged 20-60 were examined and tested for the study.

Blood tests included:

  • Creatinine
  • Carbon dioxide combining power

Participants were diagnosed with Hashimotoâs disease based on the presence of thyroid antibodies and abnormalities on a thyroid ultrasound.

They excluded individuals who were taking thyroid medication, pregnant, history of thyroid operations, or a history of autoimmune disease. The average age was 36 with 75% being women and 25% men.

What Should I Do To Prepare For A Thyroid Function Test

Thyroid function tests usually require very little preparation.

You dont need to fast before the blood test. And it doesnt matter if you have taken your thyroid medicine just before the blood test.

Tell your doctor if you are taking any medication, as some medicines can alter the test results and how they are interpreted.

It is also important to mention if you have had any X-ray tests that have used a special contrast dye, as this may contain iodine which can affect the results. Levels of thyroid chemicals also change in pregnancy, so tell your doctor if you are pregnant when the test is taken.

Note: all newborn children have their thyroid function tested as part of the heel prick test which is offered to all babies and undertaken when they are 5 days old. See the separate leaflet called Newborn Baby Screening Tests for more information.

How Much Tsh Should I Take During Pregnancy

TSH levels during pregnancy. If youre pregnant and already taking this medication for abnormal thyroid hormone levels, your doctor may recommend increasing your dose by about 30 to 50 percent. Successful treatment of high TSH and hypothyroidism during pregnancy can lower your chances of having a miscarriage.

Signs You Should Get Your Thyroid Checked

Should You Ignore Your TSH?

One tiny gland in your body that weighs under one ounce can put you into a world of hurt if it is not working correctly. That would be the thyroid gland. The Mayo Clinic notes that your thyroid is located at the base of your neck, just below the Adams apple. The gland contains hormones that regulate multiple functions in your body, including your metabolism, heart rate, and body temperature. So if it malfunctions, you can have a variety of health issues.

There are two basic ways your thyroid gland can go awry, according to EndocrineWeb.com: hyperthyroidism, in which the gland produces too much thyroid hormone, and hypothyroidism, in which it produces too little. These disorders can be caused by a variety of issues and are more common in women than in men, according to the U.S. Department of Health and Human Services.

Here are the symptoms you should watch out for that can show that the gland is overactive or underactive.

Thyroid changes can happen during pregnancy. These changes are usually not significant, but some women can develop thyroid disease during pregnancy. Hyperthyroidism occurs in about one in every 500 pregnancies, while hypothyroidism occurs in approximately one in every 250 pregnancies. Hyperthyroidism, and less often, hypothyroidism, may remain after pregnancy. If you develop a thyroid condition during pregnancy, your health care provider will monitor your condition after your baby is born. If you have a history of thyroid disease, be sure to talk with your health care provider if you are pregnant or are thinking of becoming pregnant.

What Should I Be Asking My Doctor

Since the number one cause of BOTH hypothyroidism and hyperthyroidism in the United States is autoimmune, it is important your doctor evaluate your thyroid antibodies as well as thyroid hormones annually. I recommend asking for the following test:

  • Thyroid peroxidase antibody

  • Thyroglobulin antibody

  • Thyroid stimulating hormone receptor antibodies , including thyroid stimulating immunoglobulin and thyroid binding inhibitory immunoglobulin

It is important that you specifically ask for thyroid antibodies because most traditional doctors will only run thyroid antibodies if your TSH is not normal. However, more and more research suggest that the presence of positive antibodies, even in the presence of a normal TSH, can have a negative impact on our health and our fertility.

Special Considerations For Women With A History Of Graves Disease

In addition to the dosing and testing considerations explained in this brochure, women with a history of Graves disease who were treated with radioiodine or surgical thyroidectomy should also have Graves antibodies tested early in pregnancy to assess the risk of passing antibodies on to the fetus. If antibodies are elevated, follow-up testing is recommended at weeks 18- 22, and if antibodies are still elevated, additional follow-up is recommended at weeks 30-34 to evaluate the need for fetal and neonatal monitoring.

Identify And Treat The Root Causes

Why do my thyroid hormone levels go up and down from one lab test to the next?

There are several possible underlying causes for Hashimotos that need to be tested and treated including nutrient deficiencies, adrenal dysfunction, abnormal sex hormone levels, poor iron levels, food intolerances and sensitivities especially to gluten, heavy metal toxicity, bacteria and viral infections, Candida, blood sugar imbalance, and leaky gut. Thanks to Dr. Izabella Wentzs new book Hashimotos Thyroiditis: Lifestyle Interventions for Finding and Treating the Root Cause, Hashimotos sufferers have the information they need to take control of their health.

How To Pass A Blood Test For Tsh

It is recommended to hand over the analysis on TTG in the morning on an empty stomach. At this time, the concentration of thyroid stimulating hormone is at its highest. The result can be influenced by food, therefore it is recommended to take a blood test TSH fasting. In the evening you should also pay attention to the diet and used products. It is advisable to avoid heavy and spicy foods.

From the consumption of alcoholic beverages should be discontinued one day prior to analysis. It is also preferable not to take drugs, with the exception of vital medicines. And should avoid emotional stress and heavy exercise.

What Causes Hypothyroidism

The most common cause of hypothyroidism is an autoimmune disorder called Hashimotos thyroiditis. The bodys immune system mistakenly sends out antibodies to destroy the cells in the thyroid gland. This may cause the thyroid gland to enlarge, known as goiter.

Hypothyroidism and goiter can also result from not getting enough iodine in your diet. Hypothyroidism also can occur after thyroid surgery or radioactive iodine therapy given to treat hyperthyroidism. In many cases, the specific cause of hypothyroidism is not known.

When Do You Need Treatment

Thyroid Levels

Many hypothyroid patients feel at their best when theyre on medication and their thyroid levels are in the optimal TSH range of 0.5-2.00 , Dr. Henderson says. Since lab assays and ranges vary, the optimized levels for a patients specific lab can also vary. For elderly patients, the TSH target is in the 4.0 6.0 range.

Most doctors commonly treat their hypothyroid patients with a daily dose of levothyroxine , a man-made version of the T4 thyroid hormone made by the body, some doctors recommend using both T4 and T3 as the treatment option.

With thyroid medication, the dosing has to be just right, Dr. Henderson says. Too much or too little of the medication can lead to side effects that affect a patients health.

In patients who are diagnosed as hyperthyroid, treatment can include antithyroid medications such as methimazole, that works to control the overactive thyroid. Some patients are given radioactive iodine, which is given in pill form to gradually and safely shrink the thyroid.

If you are experiencing signs of an under- or overactive thyroid, seek professional medical advice from your doctor or a specialist in endocrinology about these tests and treatments.

Understanding Thyroid Stimulating Hormone

As mentioned above, the thyroid stimulating hormone is produced by the pituitary gland. It works sort of like the master of the hormones, and rules the production of T3 and T4 from its control center.If you have too much TSH, it might mean that your thyroid gland isnt making enough T3 or T4. Remember, the TSH is supposed to stimulate the thyroid gland but if the gland isnt responding, then youll have too much TSH in your system.If your TSH levels are too low, it may mean that your thyroid gland is making too much thyroid hormone. This excessive thyroid production could actually suppress the TSH.

A word of warning for pregnant women: Its incredibly important that your hormones are balanced in pregnancy, as thyroid stimulating hormone plays a role in the development of a healthy fetus.

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.

High TSH Levels: What Should You Do?

TSH is the current gold standard for diagnosis of hypothyroidism but are the current TSH levels optimal and how do they relate to Hashimotoâs disease? An excellent paper out of China entitled, âUsing Hashimoto thyroiditis as gold standard to determine the upper limit value of thyroid stimulating hormone in a Chinese cohortâ has shed some light on this important question which looked at the upper limit of TSH levels in relation to Hashimotoâs disease and hypothyroidism.

The authors begin by stating that subclinical hypothyroidism is characterized by ânormalâ T4, T3, Free T4, and Free T3 with an elevated TSH. And these patients have an increased risk of cholesterol abnormalities, heart disease, mental illness, and pregnancy complications even though their symptoms are relatively mild.

The current upper limit for ânormalâ TSH is 4.0-5.0 mU/L but some authors have stated that it should be 2.5-3.0 mU/L. The National Academy of Clinical Biochemists guidelines have stated that 95% of normal individuals have a TSH below 2.5 mU/L which tends to be the upper limit value used by functional medicine practitioners.

What Is A Normal Tsh Level During Pregnancy

In case of hypothyroidism, TSH levels can be restored to the normal range by taking thyroid supplements every morning. says Dr Priti. The target TSH level during pregnancy, as recommended by the American Thyroid Association, is 0.3-3.0 mIU/L but note that your laboratory or doctor might use a slightly different range.

What Does Your Tsh Mean

We’ve been talking a lot about the TSH so far but I haven’t really explained what it is and why it is important.

The TSH stands for Thyroid Stimulating Hormone and it is one of the lab tests used to assess thyroid function in both pregnant and non-pregnant women.

Your body produces TSH to stimulate the thyroid gland to produce thyroid hormone.

It sounds simple to understand, and it is, but it’s a little bit counterintuitive.

A low TSH is usually an indication of hyperthyroidism while a high TSH is usually indicative of hypothyroidism.

In pregnancy, a high TSH is an indication that your body is not producing enough thyroid hormone which means you may need to use thyroid medication.

As you take thyroid medication your TSH will begin to lower.

So, if you become pregnant and find that your TSH is 5.0 that is an indication that you need to take thyroid medication to help supplement the hormone that your body is producing.

As you take thyroid medication your TSH will fall to a lower level.

Doctors use the TSH to help determine how much thyroid medication you may need.

Following the example illustrated above it may look something like this:

This is generally how the TSH is used both in pregnancy and outside of it.

Even though we are discussing the TSH in this article, it’s still important to know that they are other tests that can also be used to test your thyroid.

These other tests include the free thyroid hormones free T3 and free T4.

What Do The Results From My Thyroid Function Test Mean

Your doctor will discuss the results of your thyroid function test with you.An abnormal TSH usually indicates a deficiency or an excess of thyroid hormones available to your body, but it does not indicate why this is happening. An abnormal TSH result is usually followed by additional testing of FT3 and/or FT4 to investigate the cause.A high TSH result:

  • often means an underactive thyroid gland
  • can also occur if you have an underactive thyroid gland and are receiving too little thyroid hormone medication
  • can indicate in rare cases a problem with your pituitary gland, such as a tumour.

A low TSH result:

  • can indicate an overactive thyroid gland or damage to your pituitary gland that prevents it from producing TSH
  • can also occur if you have an underactive thyroid gland and are receiving too much thyroid hormone medication.

Are Test Results Accurate

Pin on Hypothyroidism

Although no test is 100% correct all the time, your TSH test is likely to reflect your level of thyroid-stimulating hormone accurately. Most labs now use a highly precise, third-generation testing process for TSH. This method of testing is accurate to within 0.01 mIU/L. Some labs use an older, second-generation testing method, which is accurate to within 0.1 mIU/L.

It is important to bear in mind that thyroid tests are a snapshot of what is going on in your body at the moment the test sample is taken. Your TSH levels may fluctuate based on factors discussed above, such as pregnancy, illness, and age.

What Is A Tsh Test

Thyroid testsBlood tests to measure thyroid hormones are readily available and widely used. Not all thyroid tests are useful in all situations.

TSH TestThe best way to initially test thyroid function is to measure the TSH level in a blood sample. Changes in TSH can serve as an “early warning system” often occurring before the actual level of thyroid hormones in the body becomes too high or too low.

A high TSH level indicates that the thyroid gland is not making enough thyroid hormone . On the other hand, a low TSH level usually indicates that the thyroid is producing too much thyroid hormone . Occasionally, a low TSH may result from an abnormality in the pituitary gland, which prevents it from making enough TSH to stimulate the thyroid . In most healthy individuals, a normal TSH value means that the thyroid is functioning properly.
