What Are The Signs Of Thyroid Problems

Why Your Doctor Is Wrong About Thyroid Testing

Hypothyroidism occurs when the thyroid gland is not producing a sufficient level of thyroxine and triiodothyronine .

Symptoms of Hypothyroidism include:

  • Fatigue or feeling tired all the time
  • Slow pulse or heart rate
  • Hair loss or thinning
  • Poor tolerance of the cold
  • Depression
  • Dry, coarse, or thickened skin
  • Constipation
  • Enlarged thyroid gland
  • Eye condition related to hyperthyroidism

LetsGetCheckeds at-home Thyroid Test will determine how your thyroid is performing by looking at thyroid-stimulating hormone , free thyroxine , and free triiodothyronine . TSH is produced by the pituitary gland in the brain and it controls the production of T3 and T4 from the Thyroid gland. The process is simple:

  • The test is shipped directly to you by next day delivery
  • Activate your test and answer a few health-related questions
  • Your health record will be reviewed by a medical team member and should you need any support services, they will be provided
  • Collect your sample at a time that suits you
  • Send your sample back to our laboratory using the pre-paid shipping label provided
  • Your sample will be processed in an anonymous and timely manner
  • Your results will be reviewed by our team of doctors. A member of our nursing team will contact you to deliver your results, discuss any next steps and offer prescriptions in some cases
  • You should consider taking a test if:

    Who Should Get Tested

    If you have symptoms of hyperthyroidism, especially if they come and go, you may benefit from requesting another test for TSH, T4, and T3 hormone levels.

    Our standard thyroid panel results came back normal, but you have the following hypothyroidism symptoms and you should consider more extensive testing for other thyroid issues:

    • Goiter
    • Fatigue
    • Sudden or unexplained weight gain
    • Puffy face
    • Painful, stiff, or swollen joints
    • Heavy, disrupted, or irregular menses
    • Thinning hair
    • History of autoimmune disease
    • Macrocytic anemia

    Chances are if you went to your doctor to discuss thyroid problems, he or she ordered a thyroid-stimulating hormone test. He or she may have also ordered a thyroxine test. However, these tests do not necessarily rule out uncommon thyroid disorders. You may have fallen into the thyroid testing gap.

    What Should I Do To Prepare For A Thyroid Function Test

    Thyroid function tests usually require very little preparation.

    You don’t need to fast before the blood test. And it doesn’t 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.;

    Why Hypothyroidism Is Not Diagnosed On Symptoms Alone

    Many of the symptoms of hypothyroidism are fairly common complaints found in people with a normally functioning thyroid gland, so it can be hard to decipher if the symptoms are related to the thyroid. One of the best ways to figure out if your symptoms could be related to a thyroid condition is to consider how long you have been experiencing them.;

    For example, have you always felt cold when others were warm? Did you just start to notice decreased energy? If you are starting to notice new signs and symptoms, it could be related to a thyroid issue. However, only a physician can diagnose a thyroid problem.

    Types Of Thyroid Disorders

    One Simple and Effective Test to Check Your Thyroid With A ...

    Why do we even care about thyroid disorders?

    Because your thyroid could be considered the “master hormone” in the body which regulates and helps control various other hormones and metabolic functions.;

    Thyroid hormone is produced through an endocrine gland that sits in your neck.;

    It produces thyroid hormone which enters the bloodstream and impacts almost every cell in your body.;

    Small changes to circulating thyroid hormones in the bloodstream may result in big symptoms in your body.;

    One of the big issues with thyroid related problems is that they are incredibly common with up to 1 in 5 people in the United States experiencing some type of thyroid related issues .

    So what types of symptoms might you experience if you have thyroid problems?

    The symptoms can certainly vary but because thyroid hormone helps regulate your body weight one of the most common symptoms that patients with thyroid problems experience changes in their weight.;

    This could be manifested as an increase in weight or a decrease in weight .;

    Patients also may experience changes to how they tolerate certain conditions such as cold or heat and they may experience cosmetic changes such as hair loss, dry skin, and damage to their nail beds.;

    The bottom line is that thyroid hormone helps control how you feel on the inside and how you look on the outside – making it one of the most important hormone systems in the body.;

    Thyroid Health Menstrual Cycle And Bbt

    Since women are 75% more likely to have a thyroid problem, we should obviously address the role of menstruation in the BBT reading. ;If you are menstruating, your temperature will naturally be higher during ovulation as it makes the egg more fertile. ;This increase in temperature will skew the results.

    For this reason, menstruating women should not take the test during ovulation but instead should begin on the 2nd;day of menstruation and should never get closer to 4 days pre-ovulation for accurate readings.

    Medical History And Physical Exam

    If you have any signs or symptoms that suggest you might have thyroid cancer, your health care professional will want to know your complete medical history. You will be asked questions about your possible risk factors, symptoms, and any other health problems or concerns. If someone in your family has had thyroid cancer or tumors called pheochromocytomas, it is important to tell your doctor, as you might be at high risk for this disease.

    Your doctor will examine you to get more information about possible signs of thyroid cancer and other health problems. During the exam, the doctor will pay special attention to the size and firmness of your thyroid and any enlarged lymph nodes in your neck.

    Thyroid Problems What Most Doctors Miss

    Thyroid problems are at an all time high.

    I dont think a week goes by without having a new patient come in who is taking some form of thyroid medication.

    According to the American Association of Clinical Endocrinologists, more than 27 million Americans suffer from thyroid problems Wow, that is a lot of people! And if you look at all the symptoms that are associated with thyroid disease, there are more out there suffering that have simply not been diagnosed.

    But before we go any further, lets get to know that little gland in the neck. The thyroid may be little, but its daily functions are a huge responsibility! It is associated with fat metabolism, temperature regulation, bone metabolism, growth hormone production, blood sugar metabolism, estrogen metabolism, bowel motility and so much more.

    As a result, some of the symptoms that can occur if your thyroid is dysfunctioning are:

    FatigueHeadachesExcessive Sleep Yet Still Tired

    As you read this list, you are probably saying to yourself, Wow, this sounds like me, but my doctor already told me that my thyroid was normal.

    Now, the reason most doctors will say that is because they base their analysis of thyroid dysfunction on one, or, if you are lucky, two blood levels. But that is an incomplete assessment of thyroid function. Let me explain

    Let me back up a moment and explain

    OK, Doc so how do I find out the actual cause of my thyroid dysfunction?

    How Does The Thyroid Gland Function

    How To Test for Hashimoto’s Thyroid Disease- How Do I Know If I Have Autoimmune Thyroid Disease?

    The major thyroid hormone secreted by the thyroid gland is thyroxine, also called T4 because it contains four iodine atoms. To exert its effects, T4 is converted to triiodothyronine by the removal of an iodine atom. This occurs mainly in the liver and in certain tissues where T3 acts, such as in the brain. The amount of T4 produced by the thyroid gland is controlled by another hormone, which is made in the pituitary gland located at the base of the brain, called thyroid stimulating hormone . The amount of TSH that the pituitary sends into the bloodstream depends on the amount of T4 that the pituitary sees. If the pituitary sees very little T4, then it produces more TSH to tell the thyroid gland to produce more T4. Once the T4 in the bloodstream goes above a certain level, the pituitarys production of TSH is shut off. In fact, the thyroid and pituitary act in many ways like a heater and a thermostat. When the heater is off and it becomes cold, the thermostat reads the temperature and turns on the heater. When the heat rises to an appropriate level, the thermostat senses this and turns off the heater. Thus, the thyroid and the pituitary, like a heater and thermostat, turn on and off. This is illustrated in the figure below.

    What Is The Best Option For Thyroid Testing Then

    Weve already established that measuring various levels of hormones in your blood can provide some useful insight, but fails to tell you the most important thing you need to know, which is how much thyroid hormone your cells are actually using.

    Today, this can only truly be estimated through measuring your Basal Metabolic Rate, which has been problematic because its impossible to walk into your doctors office in a truly basal condition.

    Believe it, or not, there is a simple and highly effective thyroid test that can measure your thyroid function in a truly basal state.

    Or if youve yet to be diagnosed, it will tell you whether or not you truly are hypothyroid and more accurately than the other testing methods mentioned above.

    This is exactly how I work with my clients.

    What Are The Complications Of Thyroid Cancer

    Most thyroid cancers respond well to treatment and arent life-threatening.

    After thyroid surgery or treatments, your body still needs thyroid hormones to function. Youll need thyroid replacement hormone therapy for life. Synthetic thyroid hormones, such as levothyroxine , take over for the thyroid hormones that your body no longer naturally produces.

    When To Seek A Second Opinion

    Some situations warrant a referral to an endocrinologist, a hormone specialist. You should ask for a referral from your primary care doctor if you find yourself in one of these situations after you or someone you’re close to is diagnosed with thyroid disease:

    • You’re pregnant or trying to get pregnant.
    • The thyroid disease is in a newborn or child.
    • You’re diagnosed with thyroid nodules or an enlarged thyroid gland .
    • You have any type of hyperthyroidism, including Graves’ disease.
    • Your hypothyroidism is caused by a problem with the pituitary gland.
    • You’re not feeling better despite treatment.

    How Do You Test For Thyroid Related Problems

    Top 5 Reasons Doctors Fail To Diagnose Hypothyroidism ...

    The best way to approach thyroid evaluation is to look at multiple points.;

    To do this we can take advantage of our knowledge of thyroid physiology and how it works.;

    For instance:

    We know that the thyroid helps to control metabolism and heart rate.;

    We can, therefore, use markers such as your basal metabolic rate and your resting heart rate to help us evaluate if the thyroid is working optimally.;

    It makes sense that those people with low thyroid function would present with a lower resting heart rate and a slower metabolism than those with normal thyroid function.;

    Not only does it make sense but it is also shown to be true in several clinical studies !

    In addition to evaluating these factors, we also want to assess thyroid serum lab tests, assess a complete set of symptoms and look at other factors that may influence thyroid function.;

    Compare this approach to the one dimensional and conventional thyroid testing which includes only one lab test – the TSH.;

    Again, all of these tests have been used in other studies and are derived from our basic understanding of thyroid physiology so we can count on them being accurate, especially when used together.;

    If you feel you have thyroid problems then consider using this 4 step approach:;

    Step #1 – Assess Serum Thyroid Lab Tests

  • Check the TSH – If your TSH is > 2 then you are hypothyroid. A TSH < 2 does not rule out hypothyroidism.
  • Check Free T3 – This value should be in the upper 1/3 of the reference range.
  • Step #2 – Assess Symptoms

    Do You Have Thyroid Symptoms With Normal Lab Results

      According to the American Thyroid Association, 12+ percent of the U.S. population will develop a thyroid condition. An estimated 20 million Americans have a thyroid disorder or disease. As many as 60 percent of those affected are unaware of their condition. Women are affected by thyroid disorders more often than men.

      If you tell your doctor you are concerned about thyroid problems, he or she will probably order a lab test. But what if the test comes back negative, yet your symptoms persist? Lets say you cant lose weight, always feel tired, and just feel terrible in general. You and your doctor are probably baffled by your normal thyroid blood test results.

      Some thyroid problems cause symptoms without showing up on the standard thyroid panel. For example, you may be symptomatic but cant detect the issue because your thyroid labs are in the normal range? If so, you may suffer from a less common thyroid disorder or thyroid-related dysfunction.

      What Tests Do Doctors Use If I Have A Thyroid Nodule

      If your health care professional finds a nodule or lump in your neck during a physical exam or on thyroid imaging tests, you may have a fine needle aspiration biopsy to see if the lump is cancerous or noncancerous.

      For this test, you will lie on an exam table and slightly bend your neck backward. A technician will clean your neck with an antiseptic and may use medicine to numb the area. An endocrinologist who treats people with endocrine gland problems like thyroid disease, or a specially trained radiologist, will place a needle through the skin and use ultrasound to guide the needle to the nodule. Small samples of tissue from the nodule will be sent to a lab for testing. This procedure usually takes less than 30 minutes. Your health care professional will talk with you about the test result when it is available.

      In general yes, but not always.

      You should observe if the value is shifting from one end of the normal range to the other.

      Such shifts might be normal caused by stress, seasonal changes, other illnesses, changes in the lifestyle, or medications. Some patients at the first stage of Hashimotos have TSH levels which are considered normal 2.54.5 mIU/L by some labs .

      The best advice is to be your own health advocate by paying attention to how youre feeling. If youre feeling off, address this with your doctor.

      How The Thyroid Works

      Just as the thyroid gland communicates with other organs through the hormone it produces, the pituitary gland in the brain communicates with the thyroid through a hormone it makesthyroid-stimulating hormone, or TSH. When the pituitary senses that thyroid hormone levels are too low, it releases more TSH to coax the thyroid into action. When the thyroid is nudged by TSH, it produces thyroid hormonea large proportion of which is thyroxine and a smaller proportion triiodothyronine . The T4 is eventually converted into T3, the “active” form that is taken up by receptors in body cells.
