Why You May Need A Thyroid Test
Women of all ages are more likely than men to have low thyroid hormone levels. However, many of their symptoms are attributed to other conditions or written off as a consequence of aging.
A blood test for levels of TSH is the most sensitive test for determining whether you have hypothyroidism. Most laboratories use 0.45 5.00 mIU/L as a normal reference range for TSH. People with TSH between 5.00 and 9.99 mIU/L often have no symptoms , but some do. Another test called T4 will be done if your TSH is in this range. A low level of T4 usually means you will benefit from thyroid hormone replacement.
Many people with hypothyroidism or subclinical hypothyroidism aren’t aware anything is wrong because they haven’t been tested. The U.S. Preventive Services Task Force doesn’t recommend thyroid screening because it hasn’t found sufficient evidence that testing thyroid hormone levels in large groups of people without symptoms is cost-effective. Dr. Garber agrees, and suggests a different approachtesting asymptomatic people who are most likely to develop thyroid disease and benefit from treatment.
Treating subclinical hypothyroidism with synthetic thyroid hormone may reduce the risk of developing more serious problems like cardiovascular disease. They note that low thyroid hormone can cause a high cholesterol level and treatment with thyroid hormone may make statin therapy unnecessary.
Inflammation The Silent Thyroid Disruptor
Written by Dr. Michael Ruscio, DNM, DC on November 18, 2013
All steps of thyroid hormone synthesis, from iodide uptake to thyroid hormone secretion, may be affected by cytokines , the effects of which are generally inhibitory. 1
How do you know if you are inflamed? If you have any of the following it is highly likely you are inflamed joint pain, muscle pain, any pain, gas, bloating, loose stools, depression, skin conditions, depression, headaches, get colds often, are overweight, have high blood pressure, smoke, eat junk food, drink excessively, there are more but this will give you an idea.
Did you know?
In experiments where people are injected with inflammatory compounds, near immediate changes in thyroid function are observed
If you are inflamed, Euthyroid Sick Syndrome is the most common manifestation of thyroid problems. Euthyroid sick syndrome basically means your lab work looks normal but you have symptoms of thyroid disease. Sound like you? Well you are certainly not alone because this is a common complaint. The reason for this is because inflammation most frequently causes problems with the conversion of T4 into T3 and/or elevations in rT3. Conventional testing usually misses these problems for two reasons. Firstly, conventional testing usually does not test for T3 or rT3 and secondly, the ranges used conventionally are generally too broad and dont identify subtle changes in your thyroid hormone levels that could be having an impact. More on this later.
Other Factors Involved In Bbt Readings
If you have an infection or a fever, do not take the test as your temperature will naturally be skewed. Infections and fevers drive up body temperature and may cause a false negative. If you notice the temperature going up and downwith large gaps between days it is a sign of adrenal hormone dysregulation.
As you age, the temperature may be lower which could definitely have to do with the thyroid, but confirmative blood testing is always the best way to know for sure. If your temperature is high, yet you have hypothyroid symptoms or have been diagnosed with hypothyroidism it may be a sign of Hashimotos thyroiditis or autoimmunity against your thyroid.
In autoimmune based hypothyroidism, at times thyroid hormones can range and there is an increased amount of inflammation within the body. Both of these mechanisms can raise the BTT. High temperatures can also be a sign of anemia or low estrogen levels.

How Is Thyroiditis Diagnosed
Tests for thyroiditis may include:
- Thyroid function tests measure the amounts of hormones in the blood. TSH comes from the pituitary gland and stimulates the thyroid gland to produce T4 and T3. The thyroid gland produces the hormones T4 and T3 that exert the action of thyroid hormone in the body. T3 and T4 are called thyroid hormones.
- Thyroid antibody tests measure thyroid antibodies that include antithyroid antibodies or thyroid receptor stimulating antibodies .
- Erythrocyte sedimentation rate indicates inflammation by measuring how fast red blood cells fall. The ESR is high in sub-acute thyroiditis.
- Ultrasound , sonogram of the thyroid, is used very frequently to evaluate the anatomy of the thyroid gland. It can show a nodule in the thyroid gland, a change in blood flow and echo texture of the gland.
- Radioactive iodine uptake measures how much radioactive iodine is absorbed by the thyroid gland. The amount is always low in the thyrotoxic phase of thyroiditis.
Types Of Subacute Thyroiditis
There are four different subtypes of subacute thyroiditis:
Subacute granulomatous thyroiditis: Thisis the most common type of subacute thyroiditis. Its mostly caused by viral infections.
Postpartum thyroiditis: This occurs in women within one year after giving birth, and usually goes away within 18 months. Women who develop this form of thyroiditis are thought to have an underlying autoimmune disease that causes the inflammation. Symptoms occur in two phases, starting with hyperthyroid symptoms and moving to hypothyroid symptoms.
Subacute lymphocytic thyroiditis: This also occurs during the postpartum period. Hyperthyroid symptoms develop earlier , and hypothyroid symptoms can last for several months after.
Palpation thyroiditis: This develops when thyroid follicles are damaged from mechanical manipulation such as repeated examination of the thyroid gland or surgery.
All of the subtypes of subacute thyroiditis follow a similar course of symptoms, with hyperthyroid developing first. The key differences are the causes.

Surgery For Thyroid Disorders
Removing the thyroid gland can cure hyperthyroidism, but the procedure is only recommended if antithyroid drugs don’t work, or if there is a large goiter. Surgery may also be recommended for patients with thyroid nodules. Once the thyroid is removed, most patients require daily supplements of thyroid hormones to avoid developing hypothyroidism.
What To Do If You Have Inflammation
Once you’ve identified if inflammation is present then you can dive a little bit deeper to try and figure out what is causing it.
In some cases, it’s quite easy, but in others, it can be more complex.
For instance, you might find that your inflammatory markers are elevated while you have back pain.
In this case, it’s easy to identify that the inflammation in your body is most likely coming from your back.
In other cases, you may have non-specific symptoms such as minor fatigue, minor weight loss or weight gain, mild changes to your skin, mild hair loss, and so on.
These symptoms don’t really point you in any specific direction so knowing inflammation is present is only half of the battle.
From here, you may need further testing into specific antibodies or areas of the body to identify the source.
Sometimes, autoimmune diseases can smolder in the body for years and years until you reach a point where the source can be identified.
This is frustrating for both patients and doctors but advanced tests can help.
Whether you’ve identified the source of inflammation, or not, it doesn’t always matter.
Because therapies that can help lower inflammation are pretty much always helpful no matter the cause.
Treatments that you can do to help reduce inflammation include:
These natural treatments have the potential to be effective for virtually ALL sources of inflammation.
So if you can’t find the source in your body, don’t fret.

What Is The Difference Between Hashimoto Thyroiditis And Hypothyroidism
Hypothyroidism is caused by a problem with your thyroid. Hashimoto thyroiditis is caused by a problem with your immune system. Hashimoto can cause hypothyroidism because it is an autoimmune disease that destroys thyroid cells. Hashimoto is the most common cause of hypothyroidism, but other factors can also cause it.
Acute Or Infectious Thyroiditis
Acute or infectious thyroiditis is usually caused by a bacterial infection. It’s rare and associated with a weakened immune system or, in children, a problem with the development of the thyroid.
Symptoms may include pain in the throat, feeling generally unwell, swelling of the thyroid gland and, sometimes, symptoms of an overactive thyroid gland or symptoms of an underactive thyroid gland.
Symptoms usually get better when the infection is treated with antibiotics.
Thyroid pain can be managed with painkillers like ibuprofen.
If symptoms are severe with signs of infection an ultrasound scan of the thyroid may be needed to check for other problems.
Children usually need an operation to remove the abnormal part of the thyroid.

The Limitations Of Self Diagnosis
There is an increase in popularity of direct-to-consumer blood testing. Increasingly, patients can order and receive their own tests without the need for a doctor.
While patient empowerment is a great byproduct of this movement there is also a danger of inadequate self treatment.
There are entire books, courses and conferences that enumerate the different uses and pitfalls of a single test – to boil it down to a few sentences can lead to misunderstanding.
If, for example, your homocysteine levels are high and you take a B vitamin to ‘fix’ the problem – you are likely not reducing your homocysteine levels OR reducing your risk of a severe cardiac event because there may be much more to what is going on than a B vitamin deficiency.
Find a functional medicine doctor who understands advanced testing and will guide you through the process of healing to become the healthiest version of yourself.
They should also have a multi-pronged approach to treatment which will involve lifestyle, diet and any necessary medication or nutritional medicines.
What Lab Work Do I Need If I Havent Proved Inflammation Yet
Patients first start with the ferritin labthat can go higher even in the presence of small inflammation, but will go even higher the longer and stronger the inflammation is going on , i.e. your body will push iron into storage, pushing it higher and higher in response to inflammation. Other inflammation labs are CRP and ESR and can be ordered from Ulta on the Recommended labwork page without a prescription. CRP is also helpful with infection-caused or antibody-caused inflammation, and ESR is helpful to show chronic inflammation. But most find their inflammation with the ferritin testits that sensitive.

How Do Doctors Treat Hypothyroidism
Hypothyroidism is treated by replacing the hormones that your own thyroid can no longer make. You will take levothyroxine, a thyroid hormone medicine identical to a hormone a healthy thyroid makes.3 Usually prescribed in pill form, this medicine is also available as a liquid and as a soft gel capsule. These newer formulas may help people with digestive problems to absorb the thyroid hormone. Your doctor may recommend taking the medicine in the morning before eating.
Your doctor will give you a blood test about 6 to 8 weeks after you begin taking the medicine, adjusting your dose if needed. Each time your dose is adjusted, youll have another blood test. Once youve reached a dose thats working for you, your doctor will probably repeat the blood test in 6 months and then once a year.
Your hypothyroidism most likely can be completely controlled with thyroid hormone medicine, as long as you take the recommended dose as instructed. Never stop taking your medicine without talking with your doctor first. Taking too much thyroid hormone medicine can cause serious problems, such as atrial fibrillation or osteoporosis.1
Is Hypothyroidism During Pregnancy A Problem
Left untreated, hypothyroidism during pregnancy can affect both mother and baby. However, thyroid medicines can help prevent problems and are safe to take during pregnancy. Many women taking thyroid hormone medicine need a higher dose during pregnancy, so contact your doctor right away if you find out youre pregnant.

Top 5 Blood Tests For Inflammation
Inflammation is one of the most insidious causes of disease that we overlook. Chronic inflammation is persistent, low-grade inflammation that can last for years. It is a precursor to accelerated aging and disease. If you are dealing with health issues it is important to get specific blood tests to evaluate your level of inflammation.
Inflammation has been linked to almost every major health problem. It inhibits optimal function of your body from a cellular level, making you a slower healer and promoting disease at the deepest level. Luckily, there are advanced tests for inflammation that can help you design an anti-inflammatory lifestyle.
There are several tests that can help determine the level of inflammation in your body. These tests should be performed routinely as a preventative measure and to monitor inflammatory status. This article will discuss what inflammation is, the top 5 tests for inflammation, and how you can test your own.
How Are Thyroid Nodules Treated
Thyroid nodules don’t always need treatment. Many nodules cause no symptoms and may even get smaller over time.
Thyroid nodules may need treatment if they grow or cause symptoms, or if there is concern that it could be a cancer. Surgery is the preferred treatment for thyroid nodules in children. This might involve removing part of or all the thyroid gland.
If needed, surgery is done in a hospital under general anesthesia, so the child is asleep and feels nothing. If only part of the thyroid is removed and the rest of the gland is healthy, a child may not need to take a thyroid hormone after surgery. If the rest of the gland isn’t healthy or if the whole thyroid is removed, the child will need to take a thyroid hormone.
Thyroid cancer is relatively uncommon. When it does happen, it is very treatable. Most thyroid cancers can be cured or controlled with treatment.

What Causes Thyroids To Swell
An enlarged thyroid can have various causes. In many cases, the bodys immune system attacks the thyroid, causing it to stop functioning properly and produce too much or too little thyroid hormone . A swollen thyroid, or goiter, can also be caused by an infection, a drug interaction, nodules in the gland, inflammation, iodine deficiency or as a reaction after pregnancy.
Benefits And Limitation Of The Self
An at-home self-exam known as the “neck check” can help you find thyroid lumps or enlargements on your own thyroid gland. These growths may point to any number of thyroid conditions from nodules and goiters to thyroid cancer.
Lumps in the neck can be caused by thyroid disease, and they can also be caused by a variety of other conditions, such as lymph node enlargement, lymphoma, an infectious abscess, or a traumatic injury.
In general, a neck check is not considered the most accurate or reliable way to identify thyroid disease. You can have serious thyroid disease if you have a completely normal neck check. On the other hand, a major growth can often be a sign of an easily treatable condition, such as an iodine deficiency.
In the end, there are limitations as to what a neck check can tell you. A 2017 report from the U.S. Preventive Services Task Force concluded that neck palpation was able to detect thyroid nodules in only 11.6% of cases. Ultrasound, an imaging procedure using sound waves, was five times more accurate in detecting abnormal growths.

The Importance Of Basal Body Temperature
Low body temperature is not only an indication of a possible thyroid or adrenal dysfunction, but it can also create an environment for worsening problems. Our body temperature is critical for optimal immune function, circulation, enzyme activity and more .
A lower than normal body temperature creates an environment that is ripe for pathogens like bacteria and viruses. The reason we create a high temperature fever when we have a bacterial infection or a flu is that the high temperature is inhospitable for the bacteria and viruses and it activates powerful immune activities within the body.
Additionally, enzymes are temperature dependent and wont function well at lower than optimal temperature ranges. A low-body temp will reduce overall enzyme activity which slows the bodies intracellular metabolism and causes an inability to buffer oxidative stress effectively. It also leads to poor digestion and sluggish gut and liver metabolism and an inability to deactivate and excrete toxins from the body.
