Hypothyroidism Overtreatment Linked To Risk Of Atrial Fibrillation

Nancy A. Melville

CHICAGO Low levels of thyroid stimulating hormone that result from the over-treatment of hypothyroidism are associated with a significantly increased risk of atrial fibrillation and stroke, according to results from a large, population-based study using data from the Veterans Health Administration.

“Our study provides new insights on the incidence of atrial fibrillation and stroke in patients being treated with exogenous thyroid hormone,” lead author Maria Papaleontiou, MD, told Medscape Medical News.

“We found that despite controlling for known cardiovascular risk factors, such as smoking, hypertension, etc, lower serum TSH was associated with both incident atrial fibrillation and stroke,” she said.

Papaleontiou, who is an assistant professor of internal medicine, Division of Metabolism, Endocrinology, and Diabetes at the University of Michigan, Ann Arbor, presented the findings at the 89th American Thyroid Association Annual Meeting.

The study received funding from the National Institute on Aging and the Michigan Biology of Cardiovascular Aging program.

Endogenous hyperthyroidism has been shown to be associated with cardiovascular risks, however, the effects of exogenous hyperthyroidism, defined as lower TSH levels caused by exogenous factors specifically medical over-treatment of hypothyroidism have not been well established.

The Connection Between Thyroid Disease And Inflammation

In 2009, the journal, Inflammation Research, published a study presenting the case that chronic inflammation is the root cause of several major diseases. As youre probably aware, inflammation plays a role in the incidence of cancer, heart disease, diabetes, autoimmunity and Alzheimers.

But the number of conditions impacted by inflammation doesnt stop at the Big Four

In fact, one of the most common health conditions in our modern world is also directly impacted by inflammation. Im talking about thyroid disorders, which affect 20 million Americans and tens of millions more worldwide.

Unfortunately, however, the contributing factor of inflammation is often overlooked when it comes to the thyroid. The good news is that with the right dietary and supplement strategy, it is possible to turn off the inflammatory response and therefore reduce your risk of disease and potentially remedy many thyroid conditions.

But before we get to that, its important that you understand the nature of inflammation

What Causes Hypothyroidism In Pregnancy

In most cases, women with hypothyroidism during pregnancy have Hashimotos disease. This autoimmune disease causes the bodys immune system to attack and damage the thyroid. When that happens, the thyroid cant produce and release high enough levels of thyroid hormones, impacting the entire body. Pregnant women with hypothyroidism may feel very tired, have a hard time dealing with cold temperatures and experience muscles cramps.

Thyroid hormones are important to your babys development while in the womb. These hormones help develop the brain and nervous system. If you have hypothyroidism, its important to control your thyroid levels during pregnancy. If your baby doesnt get enough thyroid hormone during development, the brain may not develop correctly and there could be issues later. Untreated or insufficiently treated hypothyroidism during pregnancy may lead to complications like miscarriage or preterm labor.

Caring For A Cat That Has Suffered A Stroke

  • 1Take the cat to the veterinarian immediately. The sooner the cat sees a veterinarian, the better care the animal will receive, meaning a better chance for recovery. Strokes in cats are not always as devastating to the animal as strokes tend to be in humans; however, the event is still serious and requires immediate attention.
  • You may want to call ahead as you place the cat in its carrier to tell the veterinarian the symptoms youve seen as well.
  • If it is at night, you may need to take him to the emergency veterinary hospital.
  • 2Cooperate with the veterinarian. Your vet will ask you some questions to help determine a course of action. They will ask questions about many things involving your cat’s behavior, so make sure you pay close attention to your cat. They will ask if your cat could have ingested anything like a plant, a medication, or a poison to cause the symptoms. They might also ask if there was any known trauma like a fall prior to the symptoms. They will ask about any changes in his water or food intake. They will also likely ask if there has been any vomiting, diarrhea, or general lethargy.
  • You will need to know if your cat has had his rabies vaccination recently as well.
  • These test are done for animals in a similar way to how they are done for humans.
  • If your cat has motion sickness as a symptom, a medication such as Cerenia is available to manage that.
  • If your cats appetite is down, there may be options that increase the appetite such as Mirtazapine.
  • Circulatory And Cardiovascular Systems

    Hypothyroidism slows your heart rate and weakens your heartbeat, making your heart less efficient at pumping blood out to your body. This can make you short of breath when you exercise. By narrowing your arteries, this condition can also raise blood pressure.

    Hypothyroidism can lead to high cholesterol. Together, high blood pressure and high cholesterol can increase your risk for heart disease.

    How Is Graves Disease Diagnosed

    Your healthcare provider may make a diagnosis based on your symptoms, such as an enlarged thyroid, and family history of thyroid or autoimmune disease. You may also have these tests to confirm a Graves disease diagnosis:

    There are also two types of antibodies linked with Graves disease that may be detected during your tests. These antibodies include TSI , as well as TBII .

    In some patients, there will be negative antibodies and the diagnosis will depend on their lab results , radioiodine uptake and thyroid scan.

    What Questions Should I Ask My Doctor

    If you have Graves disease, you may want to ask your healthcare provider:

    • What is the best treatment for me?
    • What are the treatment side effects?
    • Should I avoid certain medications?
    • Could surgery to remove the thyroid help me?
    • Does Graves disease cause other health problems?
    • Should I look out for signs of complications?

    What Are The Complications Of Graves Disease

    Untreated or poorly managed Graves disease increases your risk for these complications:

    • Eye disease:Thyroid eye disease, or Graves ophthalmopathy, occurs when the immune system attacks muscle and tissue around the eyes. Inflammation causes the eyes to protrude or bulge. These changes can cause double vision and light sensitivity. Severe swelling can damage the optic nerve and lead to vision loss.
    • Heart problems: Uncontrolled Graves disease can cause arrhythmia . Arrhythmia increases your risk of stroke, heart failure and other heart problems.
    • Skin problems: A small number of people with Graves disease develop red, thickened skin on their shins and feet. This condition is called Graves dermopathy or pretibial myxedema. The condition isnt painful, but it can be uncomfortable. Over-the-counter hydrocortisone creams, such as Cortizone┬«, can provide relief.
    • Thyroid storm: Dangerously high thyroid activity speeds up body functions. It causes arrhythmia, fast pulse and shock. This life-threatening condition is known as a thyroid storm. It requires fast treatment with antithyroid medications.

    Whats The Difference Between Hypothyroidism And Hyperthyroidism

    Hypothyroidism: Risks, Symptoms, and Diagnosis  Smarter ...

    In hypothyroidism, the thyroid doesnt make enough thyroid hormone.

    The difference between hypothyroidism and hyperthyroidism is quantity. In hypothyroidism, the thyroid makes very little thyroid hormone. On the flip side, someone with hyperthyroidism has a thyroid that makes too much thyroid hormone. Hyperthyroidism involves higher levels of thyroid hormones, which makes your metabolism speed up. If you have hypothyroidism, your metabolism slows down.

    Many things are the opposite between these two conditions. If you have hypothyroidism, you may have a difficult time dealing with the cold. If you have hyperthyroidism, you may not handle the heat. They are opposite extremes of thyroid function. Ideally, you should be in the middle. Treatments for both of these conditions work to get your thyroid function as close to that middle ground as possible.

    What Are The Symptoms Of Hyperthyroidism

    The symptoms of hyperthyroidism can vary from person to person and may include

    • Nervousness or irritability
    • Imaging tests, such as a thyroid scan, ultrasound, or radioactive iodine uptake test. A radioactive iodine uptake test measures how much radioactive iodine your thyroid takes up from your blood after you swallow a small amount of it.

    What Are The Treatments For Hyperthyroidism

    The treatments for hyperthyroidism include medicines, radioiodine therapy, and thyroid surgery:

    • Medicines for hyperthyroidism include
    • Antithyroid medicines, which cause your thyroid to make less thyroid hormone. You probably need to take the medicines for 1 to 2 years. In some cases, you might need to take the medicines for several years. This is the simplest treatment, but it is often not a permanent cure.
    • Beta blocker medicines, which can reduce symptoms such as tremors, rapid heartbeat, and nervousness. They work quickly and can help you feel better until other treatments take effect.
  • Radioiodine therapy is a common and effective treatment for hyperthyroidism. It involves taking radioactive iodine by mouth as a capsule or liquid. This slowly destroys the cells of the thyroid gland that produce thyroid hormone. It does not affect other body tissues. Almost everyone who has radioactive iodine treatment later develops hypothyroidism. This is because the thyroid hormone-producing cells have been destroyed. But hypothyroidism is easier to treat and causes fewer long-term health problems than hyperthyroidism.
  • Surgery to remove part or most of the thyroid gland is done in rare cases. It might be an option for people with large goiters or pregnant women who cannot take antithyroid medicines. If you have all of your thyroid removed, you will need to take thyroid medicines for the rest of your life. Some people who have part of their thyroid removed also need to take medicines.

    Different Tests To Monitor Your Thyroid Health

    Getting to Know Underactive Thyroid Symptoms

    After going through the effects of bradycardia and tachycardia, you will realize the importance of keeping tabs on the health of your thyroid gland. It may seem insignificant due to its size and appearance, but it plays an important role in maintaining a healthy heart.

    There are several tests you can undergo to make sure that your thyroid is in good condition:

    • Blood test to determine thyroid problems
    • EKG and ultrasound to assess your heart activities

    Results will determine what medications and treatments would be most suitable for you.

    Consult your doctor immediately if you have been diagnosed with hyperthyroidism and are experiencing the following symptoms: palpitations, chest discomfort, or shortness in breath. Dont readily dismiss these symptoms but have them checked promptly.

    When do you know you have a higher risk of thyroid-related health problems? You may go through this list and check instances where you will likely experience thyroid issues:

    • When you reach 60 years of age, you are more prone to thyroid-health issues.
    • When either or both of your parents have thyroid problems, chances are you will have it too.
    • If you are a woman, you are more susceptible to have thyroid problems. Only one man in every eight women is likely to have thyroid problems.
    • When your health history indicates that you have type-1 diabetes, rheumatoid arthritis, or premature gray hair

    Hypothyroidism: The Cardiac Connection

    Hypothyroidism can affect the heart and circulatory system in a number of ways. Insufficient thyroid hormone slows your heart rate. Because it also makes the arteries less elastic, blood pressure rises in order to circulate blood around the body. Elevated cholesterol levels, which contribute to narrowed, hardened arteries, are another possible consequence of low thyroid levels.

    Another noncardiac symptommuscle achesmay also be relevant. Muscle aches can be a symptom of hypothyroidism as well as a side effect of cholesterol-lowering statin medications, a condition known as statin-related myalgia. In fact, research suggests that hypothyroidism is more common in people who can’t tolerate statins. “Some experts believe that treating hypothyroidism may relieve or decrease statin-related myalgia,” says Dr. Garber.

    What Are The Eye Exercises For Diplopia

    Pencil push-up therapy: You begin in a seated position with a pencil in hand. Hold the pencil in front of your face at a distance where you are still able to clearly read the letters on the pencil, then slowly move the pencil closer to your nose while maintaining focus on the pencil. Move the pencil away from your nose once the letters on the pencil begin to blur. This exercise is commonly advised for convergence insufficiency.

    Swinging: Start by standing up and choosing an object in the distance to stare at. Now gently sway your body from side to side, as the same time keeping the object in focus the best you can. This exercise encourages your eyes to move in ways that are difficult for them.

    Eye rolling: Rolling your eyes in both directions may help coordinate eye movements and get your eyes to move inward, downwards, and in every direction. Begin by sitting down and looking straight ahead. Now roll your eyes clockwise in large motions, then counterclockwise, while blinking in-between eye movements.
