What is considered a dangerously high TSH level?
Experts don't agree on which TSH levels should be considered too high. Some suggest that TSH levels of over 2.5 milliunits per liter (mU/L) are abnormal, while others consider levels of TSH to be too high only after they have reached 4 to 5 mU/L.Oct 8, 2014
What is a critical TSH level?

If your TSH level is higher than 5.0 uIU/mL, then the lab will flag you as “high,” and you may experience the symptoms listed above 5.0 uIU/mL. Values of the TSH level more than 10.0 uIU/mL need long-term thyroid supplements.

When to Treat.
Is TSH a good test for thyroid?
Physicians are accustomed to checking thyroid-stimulating hormone (TSH) in older adults with symptoms of an over- or underactive thyroid, as it’s a fairly accurate and routine measure of thyroid function.
How to treat hypothyroidism?
Hypothyroidism can be treated easily by taking a tablet containing the thyroid hormone once a day. These tablets act to replace the thyroxine that is not being produced. This usually makes the symptoms disappear completely. Because it doesn't cause any symptoms, subclinical hypothyroidism isn't noticeable.
What does subclinical hypothyroidism mean?
Subclinical (latent) hypothyroidism means that the thyroid gland is still producing enough thyroid hormones. But some blood values may suggest the early stages of a hormone deficiency.
What hormones are produced in the pituitary gland?
This hormone is produced in the pituitary gland and acts as a trigger for the thyroid to start producing the thyroid hormones . TSH levels that are just a little too high may be the first sign of the early stages of hypothyroidism: The pituitary gland responds to lower levels of thyroid hormones by increasing TSH production to activate the thyroid.
What is the most important hormone in the body?
Thyroxine is the most important of the thyroid hormones. It helps regulate many of the body’s functions to balance your metabolism. Too little thyroxine can cause a number of different health problems. The symptoms range from cold hands to physical weakness, difficulty concentrating and depression.
Is thyroxine good for hypothyroidism?
It's not clear in which cases treatment would have advantages. If you already have noticeable (“overt” or “manifest”) hypothyroidism, the thyroid is no longer producing enough thyroid hormones. Thyroxine is the most important of the thyroid hormones.
What is the normal TSH range?
The standard reference range that your doctor will use to determine if your TSH is "normal" typically ranges from around 0.5 to 5.5 (or something similar). And your doctor will consider you "normal" if you are anywhere on this range.

What is mild hypothyroidism?
What to do about mild hypothyroidism is a subject that has been studied and debated for years. Mild hypothyroidism is also called subclinical hypothyroidism. It doesn't meet the standard definition of overt hypothyroidism. You may have no symptoms, and your thyroid function blood tests show a mixed picture.
Does thyroid disease cause heart problems?
Results of research on whether subclinical thyroid disease causes heart problems have been conflicting. However, the condition has been associated with heart and blood vessel abnormalities, and some studies suggest that treating mild hypothyroidism can improve various markers of heart structure and function.
Is T4 level normal?
Your free T4 level is normal, meaning your body is getting enough thyroid hormone. It is your TSH (thyroid stimulating hormone) level that is above the normal range, which indicates your thyroid gland has to work harder to pump out that thyroid hormone.
What does a low TSH level mean?
A low level of thyroxine and high level of TSH indicate an underactive thyroid. That's because your pituitary produces more TSH in an effort to stimulate your thyroid gland ...
Why do you need a TSH test?
TSH tests also play an important role in managing hypothyroidism. They help your doctor determine the right dosage of medication, both initially and over time. In addition, TSH tests are used to help diagnose a condition called subclinical hypothyroidism, which usually causes no outward signs or symptoms.
What is the best treatment for hypothyroidism?
Standard treatment for hypothyroidism involves daily use of the synthetic thyroid hormone levothyroxine (Levo-T, Synthroid, others). This oral medication restores adequate hormone levels, reversing the signs and symptoms of hypothyroidism. You'll likely start to feel better soon after you start treatment.
What are the side effects of a thyroid medication?

What does a high TSH mean?

Why is TSH high?
Another important cause of high TSH is due to stress and increased cortisol. Cortisol is considered our stress hormone which is released to help our body "tolerate" excessively stressful situations. Stressful situations range from lack of sleep to social pressure from jobs and back to the food we put in our body.
What does TSH stand for?
TSH stands for thyroid stimulating hormone and it is a hormone secreted by your pituitary gland. Thyroid physiology is quite complex (1) but we can break it down to an easy to understand sequence: Your hypothalamus (part of your brain) pumps out a hormone called TRH (thyrotropin-releasing hormone).
What hormones are released by TRH?
TRH then acts on your pituitary gland (another portion of your brain) to stimulate the release of TSH (thyroid stimulating hormone). TSH then enters your bloodstream and lands on receptors directly on your thyroid gland which then causes the release of thyroid hormones - T3 and T4 .
Is it normal to have a high TSH?
Having a high TSH is never normal. An elevated TSH (as defined by the reference ranges listed above) is an indication that your body is working overtime to try and increase the amount of thyroid hormone that it can produce.
What does it mean when your TSH is elevated?
An elevation in TSH is an indicator that the system is not working properly , and in this case, it means that thyroid function in the serum (T3 and T4) is low. Low levels of T3 and T4 circulate back up to the pituitary gland which tells the body that not enough thyroid hormone is being produced. Your pituitary gland compensates by increasing TSH ...
How long after thyroid hormone replacement should TSH be evaluated?
In patients with an intact hypothalamic-pituitary axis, the adequacy of thyroid hormone replacement can be followed with serial TSH assessments. However, changes in the TSH level lag behind serum thyroid hormone levels. Thus, the TSH level should be evaluated no earlier than four weeks after an adjustment in the levothyroxine dosage. The full effects of thyroid hormone replacement on the TSH level may not become apparent until after eight weeks of therapy. 12
What does TSH mean in medical terms?
Initiation and monitoring of treatment for hypothyroidism. (TSH = thyroid-stimulating hormone; T4 = thyroxine) [ corrected] Thyroid hormone replacement may have some benefits in patients with subclinical hypothyroidism, but there is also a potential for adverse effects, particularly in older patients.

A more recent article on hypothyroidism is available. Thyroid disease affects up to 0.5 percent of the population of the United States. Its prevalence is higher in women and the elderly. The management of hypothyroidism focuses on ensuring that patients receive appropriate thyroid hormone replacement therapy and monitoring their response.
How much of the population is affected by thyroid disease?
Thyroid disease affects up to 0.5 percent of the population of the United States. Its prevalence is higher in women and the elderly. The management of hypothyroidism focuses on ensuring that patients receive appropriate thyroid hormone replacement therapy and monitoring their response.

What are the physical findings of hypothyroidism?
These findings can include lowered blood pressure with bradycardia, nonpitting edema, generalized hair loss (especially along the outer third of the eyebrows), dry skin and a diminished relaxation phase of reflexes.
Is TSH elevated in primary hypothyroidism?
The evaluation of patients with new-onset hypothyroidism is quite limited. In patients with primary hypothyroidism, the thyroid-stimulating hormone (TSH) level is elevated, indicating that thyroid hormone production is insufficient to meet metabolic demands, and free thyroid hormone levels are depressed. In contrast, patients with secondary hypothyroidism have a low or undetectable TSH level.
Is there a screening for hypothyroidism?
The U.S. Preventive Services Task Force 23 does not recommend routine screening for hypothyroidism in asymptomatic persons. Recently, some expert panels 24 noted that screening may be beneficial in high-risk populations such as elderly women. However, widespread screening is not likely to be cost-effective.
