High and Low TSH Levels: What They Mean

Jan 22,  · High levels of TSH is an indicator that your thyroid is not producing enough hormones, like thyroxine (T4) and or triiodothyronine (T3). This hormonal imbalance is called primary hypothyroidism. Sometimes high TSH causes a decrease in thyroid hormones, but they are still in normal range. This is called subclinical hypothyroidism. Jun 17,  · Thus, high levels of TSH indicate that the pituitary gland is frequently stimulating an underactive thyroid. The reference range for normal TSH can vary by age and overall health status. In older adults, for example, a higher-than-normal TSH reading may, in fact, be normal.

TSH—short for thyroid-stimulating hormone—is a pituitary hormone that acts as a messenger to the thyroid gland. When released by the pituitary gland, it stimulates the production of more thyroid hormone. TSH levels are confusing and not necessarily intuitive. For example, many people question why high TSH levels can mean the thyroid is underactive and low TSH levels can mean it's overactive. Understanding exactly how the thyroid gland works can help.

Your thyroid gland produces thyroid hormone. When it functions properly, your thyroid is part tsh is high what does that mean a feedback loop with your pituitary gland that involves several key steps:.

Once you understand these thyroid basics, it's easier to understand what a low TSH and a high TSH reveal about your thyroid's function.

The normal range for TSH is between 0. As with most medical conditions and tests, however, there are exceptions to this rule. It's also important to note that normal thyroid levels may be abnormal for you. For example, a TSH greater than 3. While most laboratories define a normal TSH as between roughly 0. In addition, some physicians believe older patients should have a higher TSH for example, greater than 4.

Some of this controversy can be averted by doctors simply looking at each person as an individual. For example, a person who still has significant symptoms of hypothyroidism at a TSH of 4. In contrast, someone who has health risks such as heart disease or osteoporosis may benefit from having a goal TSH that is higher perhaps 5.

In pregnancy, TSH should not be allowed to rise above 3. A high TSH means different things depending on whether a person has known thyroid disease or not. 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 occurs because the thyroid gland produces an inadequate amount of thyroid hormones.

An elevated TSH may also occur with normal thyroid function due to the presence of antibodies and more. A high TSH may be found in people being treated for either hypo- or hyperthyroidism. With hypothyroidism, a high TSH usually means that the dose of thyroid hormone what kind of man do women want to be tsh is high what does that mean. In some cases, however, the dose is optimal, but the medication is not fully absorbed.

Many foods and medications can affect levothyroxine, and it's important to learn how to properly take thyroid hormones. With hyperthyroidism, a high TSH usually means that the treatment whether surgery, radioactive iodine, or medications was effective in turning off the overproduction of thyroid hormone, and that a person has now become hypothyroid.

A low TSH often, but not always, means that a person has an elevated level of thyroid hormones. While often associated with hyperthyroidism, a low TSH could also be a sign of central hypothyroidism. In people being treated for hypothyroidism, a low TSH level may mean:. In people being treated for hyperthyroidism, a low TSH level usually means that further treatment is needed to reduce thyroid hormone levels or that a person must continue to be monitored to make sure thyroid hormone levels return to normal such as in cases of transient thyroiditis related to pregnancy or chemotherapy treatment.

There are a number of variations and factors that can affect TSH levels. It's important to be aware of these, as treatment that is dictated solely by lab values as opposed to also considering an individual's symptoms can result in an ineffective plan. If a TSH level is surprising, sometimes simply repeating the test is the best course. Errors can occur during the blood draw, in transcribing the results, or due to mix-ups in the lab.

Statistically, there is always a risk of lab error, and results should always be interpreted along with clinical symptoms and findings. Antibodies are thought to interfere with accurate thyroid testing in roughly 1 percent of people. A number of other factors can affect TSH test results either through having an effect on actual levels of thyroid hormones or interacting with testing measures. Some of these include:.

In order to get the most accurate results, it's important to be consistent. For example, always having your test done at the same time of day. A somewhat controversial test available some places uses fingerprick rather than venous blood draw samples to evaluate thyroid function. Since the test is not currently widely available, it's unknown exactly how well the test compares with conventional TSH testing.

During diagnosis, most doctors use the TSH test to evaluate thyroid function and determine the how to teach university students course of treatment. There are times, however, when a TSH is or may be insufficient.

For instance, free T4 in addition to TSH is usually tested if a doctor suspects thyroid dysfunction arising from disease of the pituitary gland or hypothalamus. TSH is also not necessarily sufficient to monitor hypothyroidism during pregnancyand a T4 and free T4 are often recommended. Depending on the clinical situation, other thyroid tests that may be evaluated include triiodothyronine T3free T3, reverse T3and thyroid antibody tests.

What Does the Thyroid Do?

A high TSH level can mean a new diagnosis of hypothyroidism or inadequate thyroid replacement. A low TSH might mean hyperthyroidism or overtreatment of hypothyroidism. That said, there are exceptions to these interpretations, as well as what a "normal" level may be for you. Nov 18,  · A high TSH (defined below) 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 (if necessary) the TSH can be used to "track" your progress. May 28,  · High level of TSH usually indicates that you have an underactive thyroid and that it doesn’t produce enough thyroid hormones. Thyroid-stimulating hormone (TSH) 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.

Very high levels of Thyroid Stimulating Hormone indicate an underactive thyroid gland, or hypothyroidism, according to EndocrineWeb. High levels of TSH, which is diagnosed by blood tests, mean that the body is attempting to coax the thyroid gland into producing more of the thyroid hormone.

Older women are especially prone to hypothyroidism, which disturbs the normal balance of chemical reactions in the body, states Mayo Clinic.

The most common causes of hypothyroidism and its associated slower metabolism are inflammation of the thyroid gland or surgical removal of part or all of the gland during treatment for other diseases such as cancer.

Symptoms of hypothyroidism include fatigue, weakness, weight gain or difficulty losing weight, dry hair, rough skin, hair loss, sensitivity to cold, muscle cramps, constipation, depression, irritability, memory loss, irregular menstrual periods and low libido, according to Mayo Clinic. Sustained high levels of TSH can result in the formation of a goiter, or enlarged thyroid gland. Untreated hypothyroidism can lead to obesity, joint pain, infertility and heart disease.

Hypothyroidism can be managed with a daily dose of thyroid pills, and the dosage must be tailored to the individual patient.

If the dosage is too low, symptoms may continue while too much thyroid hormone can increase the risk of osteoporosis or heart attack, according to Mayo Clinic.
