What Are The Symptoms Of Hypothyroidism

Thyroid Symptoms | What Is Hypothyroidism and Hyperthyroidism?

Hypothyroidism has many symptoms that can vary from person to person. Some common symptoms of hypothyroidism include

  • fatigue
  • thyroiditis, or inflammation of the thyroid
  • congenital hypothyroidism, or hypothyroidism that is present at birth
  • surgical removal of part or all of the thyroid
  • radiation treatment of the thyroid
  • some medicines

Less often, hypothyroidism is caused by too much or too little iodine in the diet or by disorders of the pituitary gland or hypothalamus.1 Iodine deficiency, however, is extremely rare in the United States.

Too Much Thyroid Hormone Medicine

Some people who take thyroid hormone medicine for hypothyroidism may take too much. If you take thyroid hormone medicine, you should see your doctor at least once a year to have your thyroid hormone levels checked. You may need to adjust your dose if your thyroid hormone level is too high.

Some other medicines may also interact with thyroid hormone medicine to raise hormone levels. If you take thyroid hormone medicine, ask your doctor about interactions when starting new medicines.

Effect Of Hypothyroid Treatment On The Heart

Treatment with levothyroxine in those with overt thyroid dysfunction has been shown to improve LDL cholesterol, total cholesterol, triglycerides, hypertension, diastolic dysfunction, heart rate, and heart rate variability in exercise and to delay progression of atherosclerosis. Patients with cardiomyopathies may demonstrate improved cardiac contractility and stroke volume with levothyroxine treatment. One of the main concerns with starting levothyroxine replacement is the precipitation of myocardial ischemia or arrhythmias, which, although rare, are known to occur. The recommendation for these patients is usually to start with low doses and gradually escalate until euthyroid status is achieved.

Heart Failure And Hypothyroidism

As described earlier, hypothyroidism can affect cardiac contractility, which is often diastolic in nature, and impair cardiac muscle relaxation. Associated diastolic hypertension and sometimes-coexistent coronary artery disease further affect myocardial diastolic function. Cardiac echocardiography has demonstrated impaired relaxation in patients with overt and subclinical hypothyroidism. In addition, early impaired relaxation has been demonstrated by prolongation of the isovolumetric relaxation time and reduction in the E/A ratio in subclinical hypothyroidism. The E/A ratio is a ratio of early to late ventricular filling velocities, and a reduced E/A ratio signifies diastolic dysfunction from impaired relaxation. Consequently, it results in a state of low cardiac output with decreased heart rate and stroke volume. It is well known that protein-rich pericardial and/or pleural effusion often occurs in hypothyroidism as a result of increased vascular permeability. In advanced heart failure and shortly after myocardial infarction, the conversion of T4 to T3 decreases. Since T3 is the main regulator of gene expression in myocardial muscle, this decrease has been thought to affect myocardial contractility and remodeling. Low free T3 levels also have been associated with increased mortality in patients with heart disease.

How Are Thyroid Problems Diagnosed

Usually patients with thyroid disease see their doctor when they develop any of the signs or symptoms above. Based on that, plus a physical exam, the next step is to get blood work done.

A blood test for thyroid stimulating hormone is the best screening test for thyroid problems. Because TSH stimulates production of your thyroid hormones, TSH is high when your body is not making enough thyroid hormone and low when it makes too much . Blood tests can also show levels of antibodies in the case of Hashimotos thyroiditis or Graves disease. Your body produces antibodies to fight off foreign invaders such as viruses or bacteria, and antibodies in your blood could mean that your body is treating your thyroid as a threat.

Depending on what those tests show, your doctor may want to get a scan of your thyroid gland. Ultrasound is a commonly used imaging method, especially for hyperthyroidism.

Thyroiditis May Be To Blame For Switching Between Hypo

What could be causing me to swing back and forth between hypo- and hyperthyroidism?

Answer:You may be switching between these two disorders for several reasons. Before exploring possible causes, though, it’s important that you get a definitive diagnosis of hypothyroidism or hyperthyroidism, if you haven’t done so already.

The thyroid, a small gland at the base of the front of the neck, produces hormones that help control body temperature, influence the heart rate, regulate the production of protein and maintain the rate at which the body uses fats and carbohydrates.

An underactive thyroid doesn’t produce enough hormone. An overactive thyroid produces too much hormone. Symptoms may include unintentional weight gain or loss, persistent fatigue, palpitations, and sensitivity to hot or cold temperatures. But because other health problems cause similar symptoms, diagnosing hypothyroidism or hyperthyroidism based on symptoms alone is not possible. Instead, a blood test that measures your level of thyroid hormone is required. If a blood test confirms hypo- or hyperthyroidism and verifies that you have switched between them, there could be several possible explanations.

Two main types of thyroiditis exist. The first, subacute thyroiditis, involves pain that begins at the front of the neck and shoots toward the ears. Subacute thyroiditis is caused by a virus and often resolves on its own, without lasting problems.

What is hypothyroidism and hyperthyroidism and what are their symptoms?

If you have diabetes, youre at a higher risk of developing a thyroid disease than people without diabetes. Type 1 diabetes is an autoimmune disorder. If you already have one autoimmune disorder, you are more likely to develop another one.

For people with type 2 diabetes, the risk is lower, but still there. If you have type 2 diabetes, youre more likely to develop a thyroid disease later in life.

Regular testing is recommended to check for thyroid issues. Those with type 1 diabetes may be tested more often immediately after diagnosis and then every year or so than people with type 2 diabetes. There isnt a regular schedule for testing if you have type 2 diabetes, however your healthcare provider may suggest a schedule for testing over time.

If you have diabetes and get a positive thyroid test, there are a few things to you can do to help feel the best possible. These tips include:

  • Getting enough sleep.
  • Taking all of your medications as directed.
  • Getting tested regularly as directed by your healthcare provider.

Thyroid Surgery And Treatment As Causes Of Hypothyroidism

Thyroid treatment and surgery can lead to hypothyroidism.

Several conditions such as hyperthyroidism, goiters, thyroid nodules, and thyroid cancer can be treated by partially or fully removing the thyroid gland. This may result in hypothyroidism.

Radiation treatment of the thyroid can also lead to hypothyroidism. Radioactive iodine is a common treatment for hyperthyroidism. It works by destroying the cells of the thyroid gland and decreasing the production of T4.

Radiation is also used to treat people with head and neck cancers, Hodgkins disease, and other lymphomas, which can lead to damage of the thyroid gland.

How Long After My Thyroid Is Removed Will My Tiredness Go Away

Typically, you will be given medication to help with your symptoms right after surgery. Your body actually has thyroid hormone still circulating throughout it, even after the thyroid has been removed. The hormones can still be in your body for two to three weeks. Medication will reintroduce new hormones into your body after the thyroid has been removed. If you are still feeling tired after surgery, remember that this can be a normal part of recovering from any type of surgery. It takes time for your body to heal. Talk to your healthcare provider if you are still experiencing fatigue and other symptoms of thyroid disease after surgery.

What Should I Do If I Think I Have Hyperthyroidism

If you are concerned that you may have an excess amount of thyroid hormone, you should mention your symptoms to your doctor. A simple blood test is the first step in the diagnosis. From there, both you and your doctor can decide what the next step should be. If treatment is needed, it is important for you to let your doctor know of any concerns or questions you have about the options available. Remember that thyroid disease is very common, and the diseases that cause an excess of thyroid hormones can be easily diagnosed and treated.

Complications Prognosis And Outlook For Thyroid Conditions

The overall outlook and prognosis varies between hypothyroidism and hyperthyroidism. With hypothyroidism, your levels and overall symptoms may improve with medication, but its a condition youll likely be treating for the rest of your life.

This is not necessarily the case with hyperthyroidism. If antithyroid medications work, then your thyroid hormone levels will normalize without any further issues.

Once you have any form of thyroid disease though, your doctor will monitor your condition with occasional blood tests to make sure your thyroid hormones are at optimal levels.

Complications of thyroid disease may include:

  • Anxiety
  • Depression
  • Weight fluctuations
  • High blood pressure

Hyperthyroidism Vs Hypothyroidism Treatment

Is hypothyroidism curable? There is no cure for a hypothyroidism diagnosis, but there may be ways to naturally increase thyroid hormone production through dietary means, such as a hypothyroidism diet. The conventional treatment for hypothyroidism is levothyroxine sodium tablets, also known as Synthroid. This medication is taken as a synthetic hormone replacement to help regulate thyroid levels. Doctors typically recommend taking this medication daily for the rest of ones life.

The first step in natural treatment of hypothyroidism is to eliminate the causes of thyroid dysfunction, such as inflammation, overuse of medications, nutrient deficiencies and changes in hormones due to stress. The hypothyroidism diet eliminates foods that can cause inflammation and immune reactions and instead focuses on foods that help heal the GI tract, balance hormones and reduce inflammation.

What about conventional treatment of hyperthyroidism? There are medications commonly prescribed to limit the activity of a hyper thyroid such as Methimazole or Propylthiouracil . Surgery may be another conventional recommendation as a last resort to remove all or part of the thyroid if anti-thyroid medications do not work. Its worth researching ways to treat hyperthyroidism naturally, as removing sources of inflammation from your diet and taking advantage of thyroid-supporting supplements and essential oils may help make a huge difference.

Faq: Frequently Asked Questions

Hyperthyroidism

Is Graves disease the same as hyperthyroidism?

Graves disease is an autoimmune disorder that leads to and is the most common cause of hyperthyroidism, but theyre not the same thing. While all patients with Graves disease have hyperthyroidism, patients with hyperthyroidism may not necessarily have Graves disease .

In Graves disease, the body makes an antibody called thyroid-stimulating immunoglobulin , which causes the thyroid gland to make too much thyroid hormone . Graves disease runs in families and is more commonly found in women.

Hypothyroidism vs Hyperthyroidism: Whats the difference?

The difference all comes down to the prefix in each word: hyper means over or exaggeration, while hypo means under or beneath. When it comes to -thyroidism, hyper- means an overactive thyroid gland, and hypo- means an underactive one.

Hypothyroidism, or an underactive thyroid gland, can actually be caused by treatments for hyperthyroidism, since their whole purpose is to decrease thyroid gland activity. Those treatments, however, can tip the balance too far.

What should I eat to manage hyperthyroidism?

With hyperthyroidism, its more important to manage what you dont eat. High levels of iodine consumption can exacerbate hyperthyroidism, so its a good idea to watch your iodine intake. Look for ways to limit iodine in your diet by restricting your consumption of foods such as: fish, seaweed, shrimp, dairy products, and grain products .

How Is Thyroid Disease Treated

Your healthcare providers goal is to return your thyroid hormone levels to normal. This can be done in a variety of ways and each specific treatment will depend on the cause of your thyroid condition.

If you have high levels of thyroid hormones , treatment options can include:

  • Anti-thyroid drugs : These are medications that stop your thyroid from making hormones.
