Can Dizziness Be Caused By Thyroid Problems

Tsh Thyroid Stimulating Hormone

Hashimoto’s Causes Vestibular System Damage (Vertigo, Dizziness, Balance Problems)

TSH is the hormone that tells your thyroid to make more thyroid hormone. Heres how it works.

Your hypothalamus is like the thermostat for thyroid hormone it keeps watch on how much thyroid hormone is in your bloodstream, and it responds when you need more. When your level drops too low, it releases TRH, thyroid releasing hormone. Your pituitary gland picks up on TRH, and it releases TSH in response.

Does it test thyroid function? Well, yes, but only if your hypothalamus and pituitary are doing their thing. The stops on the signaling pathway can get messed up for various reasons. Any problems with detecting hormone or releasing hormone at any point in the cascade, and the TSH test becomes worthless.

TSH Optimal range: 0.5-2 IU/L

High TSHHigh TSH indicates youre hypothyroid. Since its a signaling hormone, high TSH indicates that your body detects low hormone, so its turning up the volume on the signal to make more. If your thyroid isnt or cannot respond because its compromised in some way, youll produce more and more TSH. This number can really go off the charts, depending on how low you are and how long youve been hypothyroid.

Low TSHLow TSH tells you that you have too much thyroid hormone, or that you can cut your dose of thyroid medication, so it indicates hyperthyroid. Certain thyroid medications can suppress your TSH, so if you dont have symptoms youre still in good shape.

Heart Conditions Which Cause Dizziness

The heart is an electrical pump and for it to work, the electrical conduction system must be operating properly to stimulate the heart muscle to squeeze in a coordinated fashion and pump blood to the body. The heart muscle itself must be strong enough to pump blood, and the valves in the heart must work properly to allow blood to flow in the direction intended during contraction.

  • Conduction disturbances: Electrical conduction disturbances may make the heart beat too quickly or too slowly , and either of these situations may result in an inadequate blood supply to the brain, causing dizziness or lightheadedness.
  • Cardiomyopathy: Dizziness is also a symptom of cardiomyopathy , a disease of the heart muscle, resulting in muscle that doesn’t squeeze effectively. Most commonly the weakness is due to atheroscleroticheart disease or ischemic cardiomyopathy , in which the heart muscle itself doesn’t get enough blood supply to work properly. Other non-ischemic cardiomyopathies may be due to diabetes, alcohol use, and viral infections.

Causes Of Balance Disorder: Whats Throwing You Off Balance

Weve all experienced a dizzy spell at some point or the other. But if your sense of balance takes a hit regularly, you have reason to worry. Although we tend to take it pretty much for granted, maintaining balance is a complicated function. And your ear plays a crucial role in this function. Your inner ear, which is known as the labyrinth, contains a complicated system of small tubes known as semicircular canals, nerves, and fluid which tell your brain how your body is positioned and when a movement is causing you to change position.

Being off balance can describe a range of feelings. For instance, you may feel light-headed or experience vertigo, as though your surroundings are spinning. Some people feel like theyre walking on a wobbly surface like a mattress or cotton wool, while others may feel like theyre drunk or even on an unsteady boat. People with a balance disorder may stagger while walking or fall or teeter while trying to stand up.

Various factors can disrupt this complex system and cause balance problems:123

How Is Dizziness Diagnosed

    The diagnosis of dizziness begins with the health care professional deciding whether the complaint of dizziness refers to lightheadedness or vertigo. Further diagnosis continues once this distinction is made.

    The key to the diagnosis of dizziness is a thorough history and physical examination. Often the diagnosis is made by listening to the patient’s story. The health care professional may ask about triggers that cause and relieve the symptoms of dizziness.

    • “Is it related to changing positions quickly?”
    • “Does it resolve on its own or does the patient have to do something, like lie down to make it better?”
    • “Does turning the head bring on the symptoms? Do the symptoms resolve when the patient is very still?”
    • “Is there associated hearing loss or ringing in the ears?”

    A review of systems is a series of questions that review the patient’s body functions. The doctor may ask questions about associated symptoms including fever, vomiting, diarrhea, chest pain, shortness of breath, palpitations, or abnormal bleeding.

    The doctor may review the past medical history, and this includes reviewing medications the patient is currently taking.

    The doctor may do a thorough physical examination that may include:

    Imaging studies and blood tests: The need for imaging studies and/or blood tests will depend on the concerns the health care professional and patient have in regard to the cause of the dizziness. Common tests that may be ordered include:

    Signs And Symptoms Of Hypothyroidism

    Chances are, youve landed here and youre reading this because youre having a heck of a time navigating thyroid testing and diagnosis. Maybe you know somethings up, but your tests are coming back normal, or you feel like youre not getting the full picture.

    Youre not alone. If youre going to a western medicine doctor for thyroid symptoms, you might have some back and forth, even some second or third opinions before you get the information you need.

    Functional medicine and naturopathic doctors are simply better at diagnosing and treating the thyroid. The difference lies in the tests ordered and whats considered normal. There are exceptions doctors are out there who fully understand how hormone levels, blood tests, medications, and individual differences between patients all work. But, youll need to do some digging to find Dr. Right, as Bulletproof Radio podcast guest Izabella Wentz calls them.

    When theyre licensed in your state, functional medicine and naturopathic doctors can order all of the blood tests and prescriptions you might need, and theyre likely to incorporate non-medical interventions as well.

    A lot of docs will use TSH only as in the indicator of your thyroid function. If thats the case, you might want to go doctor shopping.

    Here are the thyroid tests that will give you the full picture of how everythings working:

    What Causes Thyroid Disease

    The two main types of thyroid disease are hypothyroidism and hyperthyroidism. Both conditions can be caused by other diseases that impact the way the thyroid gland works.

    Conditions that can cause hypothyroidism include:

    • Thyroiditis: This condition is an inflammation of the thyroid gland. Thyroiditis can lower the amount of hormones your thyroid produces.
    • Hashimotos thyroiditis: A painless disease, Hashimotos thyroiditis is an autoimmune condition where the bodys cells attack and damage the thyroid. This is an inherited condition.
    • Postpartum thyroiditis: This condition occurs in 5% to 9% of women after childbirth. Its usually a temporary condition.
    • Iodine deficiency: Iodine is used by the thyroid to produce hormones. An iodine deficiency is an issue that affects several million people around the world..
    • A non-functioning thyroid gland: Sometimes, the thyroid gland doesnt work correctly from birth. This affects about 1 in 4,000 newborns. If left untreated, the child could have both physical and mental issues in the future. All newborns are given a screening blood test in the hospital to check their thyroid function.

    Conditions that can cause hyperthyroidism include:

    Adrenal Dizziness: Not Your Usual Dizzy Spell

    Dizziness, in AFS, is not the typical dizziness associated with vertigo. Vertigo, in this case, is described as having light-headedness described as a sensation of floating or near fainting. Many times, imbalance and unsteadiness can result. During this time, blood pressure and all cardiovascular and neurological markers are usually normal.

    Many causes can be responsible for the AFS light-headedness. Among some, are metabolic issues such as sugar imbalance, autonomic nervous system imbalances, ear problems, and chronic, prolonged, intense stress.

    When To See A Doctor

    It is vital for people with unexplained fatigue or other signs or symptoms of hypothyroidism to see a doctor. Without treatment, an underactive thyroid can lead to serious complications, such as infertility, obesity, and heart disease.

    A doctor can carry out a simple blood test to check a persons thyroid hormone levels. Treatment for hypothyroidism involves taking synthetic thyroid hormones. These medications are safe and effective once a person takes the right dose.

    Your Ears Balance System Controls Blood Flow

    What Causes Vertigo? What Causes Dizziness?

    Weve learned that our inner-ear balance system contributes to the control of our blood flow, says Whitman, and that the inner ear has the ability to know which way is up. When you move from lying down to standing up, two inner ear structures, the utricle and saccule, detect gravity. They tell your cardiovascular system to direct blood flow to accommodate your change in position, says Whitman. When that process goes awry, it may cause dizziness.

    What Is Dizziness Actually

    We come across the term dizziness all the time, or we often feel dizzy, but have you ever wondered what it is actually? Dizziness is a term that refers to an array of sensations such as feeling woozy, faint, unsteady, or weak. Sometimes people feel like their surroundings are spinning around them and say theyre dizzy, but in fact, thats just a form of dizziness called vertigo. Lightheadedness is one of the most common reasons why people schedule an appointment to see their doctor or health care provider.

    It is worth noting that dizziness is not a standalone disease or health condition, but rather a symptom that occurs due to a wide range of health problems. Thats exactly why dizziness is not something you should ignore. Multiple diseases can make us feel dizzy, but your doctor can make an accurate diagnosis and find the root cause.

    How Are Hashimotos Flare

    Hashimotos thyroiditis that causes hypothyroidism is treated with a medication called levothyroxine. This is a synthetic version of thyroid hormone that helps replace the hormones that your thyroid isnt producing.

    The proper dose of levothyroxine is different for everyone. If youre taking the correct dose of levothyroxine, you shouldnt experience a flare-up.

    Since a variety of factors can impact your thyroid as well as the effectiveness of levothyroxine, its important to have your thyroid levels checked regularly. These factors include:

    • diet

    Thyroid Dysfunction And Menieres Disease: Is There A Relationship By Timothy Hain And Patthida Maroongroge

    The set of symptoms described as Menieres disease may have several causative factors. Timothy Hain and Patthida Maroongroge look for a relationship in the literature between Menieres disease and hypothyroidism.

    Menieres disease affects around two in 1000 people and is one of the most common causes of dizziness deriving from the inner ear. Although MD is nearly always accompanied with endolymphatic hydrops , temporal bone studies find hydrops in a far greater proportion of normal temporal bones than would be expected from the prevalence of Menieres disease in the population.

    Accordingly, the aetiology of MD is believed to be multifactorial. Metabolic and endocrine dysfunction, as well as autoimmune disturbance, have been suggested to be contributing factors to causation of MD. In particular, there is evidence in the literature that thyroid disorders, specifically hypothyroidism and autoimmune thyroiditis, play a role in MD .

    Figure 1a. Normal membranous labyrinth.

    Figure 1b. Dilated membranous labyrinth in Menieres disease .

    The proportion of treated hypothyroidism was 32% in the group of 50 patients with MD, as opposed to 4% in the control group.

    Figure 2. Hashimotos thyroiditis.

    The association between MD and hypothyroidism seems to be related to an autoimmune mechanism rather than reduced thyroid hormone.

    . Also to know is, what is the main cause of thyroid problems?

    Causes of thyroid problems. Problems with the thyroid can be caused by: iodine deficiency. autoimmune diseases, in which your immune system attacks your own body, leading either to hyperthyroidism or hypothyroidism

    Subsequently, question is, what causes thyroid problems in females? When your thyroid doesnt produce enough hormones, the balance of chemical reactions in your body can be upset. There can be a number of causes, including autoimmune disease, hyperthyroidism treatments, radiation therapy, thyroid surgery and certain medications.

    Accordingly, is TSH affected by stress?

    Although the link has not been proven, experts speculate that stress may affect this function. Cortisol, the main hormone produced in response to stress, can suppress pituitary function and keep the thyroid-stimulating hormone from being released, thereby inducing hypothyroidism, according to Dr. Wasser.

    What emotional problems does hypothyroidism cause?

    In both thyroid disorders you may also suffer from mood swings or short temper and difficulties in sleeping. Generally the more severe the thyroid disease the more severe the mood changes. All this is caused either by abnormal or rapidly changing thyroid levels or canbe a side effect of treatment.

    What Causes Dizziness: Many Root Causes

    There are many possible causes of dizziness. It can often be seen in a variety of conditions. Stress overload and intense anxiety can sometimes lead to disorders of the cerebellum. This happens when sensory signals experience a kind of short-circuit. Many times, an imbalance or unsteadiness results. A dysfunctional nervous system and cardiovascular system can also be the cause of headaches, along with side effects of prescription medications. If you have had a conventional medical work up and no known cause is discovered, it may be time to look at adrenal fatigue syndrome as a possible cause.

    Are There Different Types Of Thyroid Removal Surgery

    If your healthcare provider determines that your thyroid needs to be removed, there are a couple of ways that can be done. Your thyroid may need to be completely removed or just partially. This will depend on the severity of your condition. Also, if your thyroid is very big or has a lot of growths on it, that could prevent you from being eligible for some types of surgery.

    The surgery to remove your thyroid is called a thyroidectomy. There are two main ways this surgery can be done:

    • With an incision on the front of your neck.
    • With an incision in your armpit.

    The incision on the front of your neck is more of the traditional version of a thyroidectomy. It allows your surgeon to go straight in and remove the thyroid. In many cases, this might be your best option. You may need this approach if your thyroid is particularly big or has a lot of larger nodules.

    Alternatively, there is a version of the thyroid removal surgery where your surgeon makes an incision in your armpit and then creates a tunnel to your thyroid. This tunnel is made with a special tool called an elevated retractor. It creates an opening that connects the incision in your armpit with your neck. The surgeon will use a robotic arm that will move through the tunnel to get to the thyroid. Once there, it can remove the thyroid back through the tunnel and out of the incision in your armpit.

    • Have large thyroid nodules.

    Headaches And Thyroid Function

    A recent study published in Headache: The Journal of Head and Face Pain found that thyroid and Migraines had a strong connection with 21% of people who suffered a pre-existing headache condition were more likely to develop hypothyroidism. For migraine sufferers, that number jumps to 41%.

    This isnt surprising considering past research has shown that people who suffered from migraines in early childhood often developed hypothyroidism as an adult. Research has also shown that once hypothyroidism has developed, migraines and headaches become more frequent and severe.

    Furthermore, other studies have found that as hypothyroidism increases in severity, it may result in even more frequent headaches.

    If youre one of the millions of people suffering from migraines, your immediate question may be: Can the thyroid cause headaches? While this research shows a strong link between the two conditions, there is no definitive answer as to why they are linked or if one condition causes the other.

    One of the most notable questions on the topic is: Are people who suffer from migraines are more likely to have thyroid problems, or is it that those people who have thyroid issues are more susceptible to migraines?

    It is the hope of medical professionals, researchers, and migraine sufferers alike that present and future studies will answer that question, and help develop additional protocols and treatments for those affected.

    How Does Blood Pressure Work & What Is Hypertension

    Dizziness – Thyroid and Brain Symptoms (And how to fix them!)

    Blood pressure is the measurement of what kind of pressure is being put on your blood vessels . The top number in a blood pressure reading reveals the pressure on the walls of the vessels when the heart is pumping, systolic blood pressure.

    The bottom number represents the pressure on the walls of the vessels when the heart is at rest or between beats, diastolic. Blood pressure acts diurnally, as well: higher during awake hours and lower while sleeping. Blood pressure readings consistently above 140/90 are considered hypertensive.

    Role Of Thyroid Metabolism In Vestibular Vertigo

    Anisa ., Sheetal Rai

    Abstract

    Background: Thyroid hormones play a role in the development and functioning of the inner ear. Therefore, it was hypothesized that a derangement in the thyroid hormone levels can affect the cochleo-vestibular system.

    Methods: The present study included 64 cases and 64 controls. All patients diagnosed with peripheral vertigo were enrolled into the study. All the subjects underwent thyroid function tests- serum T3, T4 and thyroid stimulating hormone . Free hormone levels were obtained in patients with subclinical hypo or hyperthyroidism. The data was analyzed using Independent sample t test.

    Results: Out of 64 cases only 10 patients showed altered thyroid values. Fifty-nine cases were diagnosed with benign paroxysmal positional vertigo out of which 9 had altered thyroid hormone levels. Among the control group, 12 were found to have deranged thyroid hormone levels.

    There is no association between functional thyroid hormone levels and BPPV. Therefore, altered thyroid metabolism has no role in the causation of vestibular dysfunction due to BPPV. However, in case of Menieres disease and Vestibular neuronitis further studies with large sample size are required to ascertain the role of functional thyroid hormones in producing vestibular symptoms.
