What Causes Thyroid Problems When You Have Cancer

Hidden Causes to Thyroid Problems with Dr. Rob

Thyroid problems have many causes. Thyroid problems can happen on their own, whether you have cancer or not. They are more common as you get older. However, thyroid problems are also a common side effect of certain types of cancer and cancer treatment.

The types of cancer and cancer treatment that raise your risk of thyroid problems include:

Thyroid cancer. Removing part or all of the thyroid gland is the main treatment for this type of cancer. This causes thyroid hormone levels to drop. The hormones are replaced with medication.

Radiation therapy to the head, neck, or upper spine. This is one of the most common causes of thyroid problems after cancer treatment. Whole-body radiation can also cause thyroid problems.

Chemotherapy. Chemotherapy, especially in high doses before a bone marrow transplant , can cause thyroid problems.

Targeted therapy. Targeted therapy is a treatment that affects specific biomarkers in the cancer. Treatments called tyrosine kinase inhibitors, or TKIs, are an example of targeted therapies that can affect your thyroid gland. This includes the drugs sunitinib , sorafenib , imatinib , nilotinib and others.

Immunotherapy. Immunotherapy is a treatment that boosts your body’s natural defenses to fight cancer. Some immunotherapy treatments can affect your thyroid. Interferon-alpha is an example of an immunotherapy drug that may lower thyroid functioning.

What Are Clinical Trials For Hypothyroidism

Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of hypothyroidism, such as

  • understanding how the disease progresses, its clinical presentation, and genetics
  • investigating how effective and safe levothyroxine is for people with chronic kidney disease

Questions To Ask The Health Care Team

Consider asking the following questions:

  • Do I have an increased risk of thyroid problems, due to the cancer or its treatment? For other reasons?

  • How will my thyroid function be checked? How often?

  • What can be done to prevent thyroid problems before cancer treatment begins?

  • What signs or symptoms should I watch for?

  • Who should I call if I have any signs of a thyroid problem?

  • Why is it important to treat thyroid problems?

  • What is the treatment for my thyroid problem?

It Produces Essential Hormones

The thyroid produces two important hormones, triiodothyronine and thyroxine .

In other words, your thyroid is;extremely important.

How Are Thyroid Diseases Diagnosed

It can be hard to tell if you have a thyroid disease. The symptoms are the same as many other health problems. Your doctor may start by asking about your health history and if any of your family members has had thyroid disease. Your doctor may also give you a physical exam and check your neck for thyroid nodules.

Depending on your symptoms, your doctor may also do other tests, such as:

  • Blood tests. Testing the level of thyroid stimulating hormone in your blood can help your doctor figure out if your thyroid is overactive or underactive. TSH tells your thyroid to make thyroid hormones. Depending on the results, your doctor might do another blood test to check levels of one or both thyroid hormones in your blood.
  • Radioactive iodine uptake test. For this test, you swallow a liquid or capsule that holds a small dose of radioactive iodine . The radioiodine collects in your thyroid because your thyroid uses iodine to make thyroid hormone.

High levels of radioiodine mean that your thyroid makes too much of the thyroid hormone. Low levels mean that your thyroid does not make enough thyroid hormone.

  • Thyroid ultrasound. The thyroid ultrasound uses sound waves to make a picture of the thyroid on a computer screen. This test can help your doctor tell what type of nodule you have and how large it is. You may need more thyroid ultrasounds over time to see if your nodule is growing or shrinking.

    Whats The Connection Between Hypothyroidism And Weight Loss

    Once youre treated for this condition, you may lose any weight that youve gained. Thats because once your thyroid levels are restored, your ability to manage your weight returns to normal.

    If youre treating hypothyroidism but dont see a change in your weight, that doesnt mean weight loss is impossible. Work with a doctor, registered dietitian, or personal trainer to develop a focused healthy-eating plan and exercise strategy that can help you lose weight. Get more tips on managing your weight when you have hypothyroidism.

    How Long Does It Take To Recover From Thyroid Surgery

    It will take your body a few weeks to recover after your thyroid is surgically removed . During this time you should avoid a few things, including:

    • Submerging your incision under water.
    • Lifting an object thats heavier than 15 pounds.
    • Doing more than light exercise.

    This generally lasts for about two weeks. After that, you can return to your normal activities.

    Radioactive Iodine Uptake Test

    A radioactive iodine uptake test, also called a thyroid uptake test, can help check thyroid function and find the cause of hyperthyroidism. The thyroid takes up iodine from the blood to make thyroid hormones, which is why this is called an uptake test. Your health care professional may ask you to avoid foods high in iodine, such as kelp, or medicines containing iodine for a week before the test.

    For this test, you will swallow a small amount of radioactive iodine in liquid or capsule form. During the test, you will sit in a chair while a technician places a device called a gamma probe in front of your neck, near your thyroid gland. The probe measures how much radioactive iodine your thyroid takes up from your blood. Measurements are often taken 4 to 6 hours after you swallow the radioactive iodine and again at 24 hours. The test takes only a few minutes.

    If your thyroid collects a large amount of radioactive iodine, you may have Graves disease, or one or more nodules that make too much thyroid hormone. You may have this test at the same time as a thyroid scan.

    Even though the test uses a small amount of radiation and is thought to be safe, you should not have this test if you are pregnant or breastfeeding.

    What Blood Tests Do Doctors Use To Check Thyroid Function

    What Causes Thyroid Problems and Hashimoto’s Disease?

    Doctors may order one or more blood tests to check your thyroid function. Tests may include thyroid stimulating hormone , T4, T3, and thyroid antibody tests.

    For these tests, a health care professional will draw blood from your arm and send it to a lab for testing. Your doctor will talk to you about your test results.

    How Is Hypothyroidism Diagnosed And What Is Subclinical Hypothyroidism

    Unfortunately, you cant diagnose yourself with a thyroid condition, be it hypothyroidism or subclinical hypothyroidism, which is when the thyroid gland is still producing sufficient thyroid hormones but some blood test levels may be abnormal.

    This is important because many symptoms of hypothyroidism may be harmless , be related to other health conditions, or simply signal regular signs of aging .

    For example, weight gain doesnt necessarily mean you have a thyroid problem, and achy muscles or joints may just be a sign that youre getting older. The best way your doctor can determine if you have hypothyroidism is through a blood test.

    Potential Dangers Of Having Hypothyroidism

    Because the body is expecting a certain amount of thyroid hormone, the pituitary will make additional thyroid stimulating hormone as a way to prompt the thyroid to produce more hormone.

    This extra work at signaling the thyroid gland to keep producing TSH may cause it to become enlarged, leading to he formation of a goiter . Left untreated, the symptoms of hypothyroidism will usually progress. Rarely, complications can result in severe life-threatening depression, heart failure, or coma.

    Hypothyroidism can often be diagnosed with a simple blood test: the thyroid hormone panel. In some persons, however, it’s not so simple and more detailed tests are needed.; Most importantly, a good relationship with a good endocrinologist will almost surely be needed. ;;

    Hypothyroidism is completely treatable in many patients simply by taking a small pill once a day. However, this is a simplified statement, and it’s not always so easy.; There are several types of thyroid hormone preparations and one type of medicine will not be the best therapy for all patients.;

    Many factors must be considered in establishing a personalized plan for the treatment of hypothyroidism and it is different for every patient.;;

    Thyroid Disease: Causes and Risk Factors

    A thyroid ultrasound may be ordered if a thyroid function test is abnormal or if you doctor feels a growth on your thyroid while examining your neck. An ultrasound can also check an underactive or overactive thyroid gland.

    You may receive a thyroid ultrasound as part of an overall physical exam. Ultrasounds can provide high-resolution images of your organs that can help your doctor better understand your general health. Your doctor may also order an ultrasound if they notice any abnormal swelling, pain, or infections so that they can uncover any underlying conditions that might be causing these symptoms.

    Ultrasounds may also be used if your doctor needs to take a biopsy of your thyroid or surrounding tissues to test for any existing conditions.

    What Are The Types Of Thyroid Disorders

      Blood tests are used to diagnose hypothyroidism or hyperthyroidism. They do not point to a specific cause. In order to determine a cause of the thyroid abnormality, the doctor will consider the patient’s history, physical examination, and medical condition. Further testing might be used to isolate an underlying cause. These tests might include more blood testing for

      • thyroid antibodies,
      • ultrasound of the thyroid gland, or
      • others.

      If thyroid cancer is suspected and surgery may be required, your physician may ask for a blood test known as thyroglobulin.

      • Thyroglobulin is a protein made only by thyroid cells.
      • If the thyroglobulin level at baseline is detectable or elevated it can be used as a tumor marker.
      • After a total thyroidectomy for cancer the level should fall to an undetectable range since the cells that make thyroglobulin have been removed.
      • If the level remains detectable after surgery, there is a possibility of thyroid tissue elsewhere in the body, and metastatic disease should be considered.
      • If the level is undetectable for a period of time after surgery and then starts to climb, a recurrence of the cancer – either at the primary site or elsewhere in the body should be considered.

      Will I Have The Same Dose Of Medication For Hypothyroidism My Entire Life

      The dose of your medication can actually change over time. At different points in your life, you may need to have the amounts of medication changed so that it manages your symptoms. This could happen because of things like weight gain or weight loss. Your levels will need to be monitored throughout your life to make sure your medication is working correctly.

      What Are Thyroid Hormones

      The thyroid gland produces hormones that are essential for normal body metabolism. Blood testing is now commonly available to determine the adequacy of the levels of thyroid hormones. These blood tests can define whether the thyroid gland’s hormone production is normal, overactive, or underactive.

      The thyroid gland is located in the lower part of the neck, below the Adam’s apple.The gland wraps around the windpipe and has a shape that is similar to a butterfly – formed by two wings and attached by a middle part .

      The thyroid gland uses iodine to produce thyroid hormones.

      • The two most important thyroid hormones are thyroxine and triiodothyronine , which account for 99.9% and 0.1% of thyroid hormones present in the blood respectively.
      • However, the hormone with the most biological activity is T3.
      • Once released from the thyroid gland into the blood, a large amount of T4 is converted into T3 – the active hormone that affects the metabolism of cells.

      Dont Do Starvation Diets

      Fad diets are popular for their quick effectiveness, but theyre objectively terrible for your body in many ways. Not only are you likely to gain all the weight back the second you stop the diet, but youre also slowing down your metabolic rate and opening yourself up to thyroid issues.

      According to a study in the Journal of Clinical Endocrinology & Metabolism, fasting causes your primary thyroid hormone that regulates metabolism to decrease efficiency by 53%. Many other thyroid hormones also saw a decrease in levels. In addition, cortisol levels leap up when you starve yourself, causing stress to you because it thinks your body is in danger. You may begin to retain a lot of fat as a result.

      So dont do starvation diets no liquid cleanses, no super low-calorie days, nothing at all that could cause your body to believe it is starving.
