Hashimoto’s Disease FAQ

What is Hashimoto’s Disease?
Hashimoto's disease affects the thyroid gland. The thyroid gland is a small butterfly-shaped gland located in the neck that produces thyroid hormones, which are important for regulating the body's metabolism.
In Hashimoto's disease, the immune system mistakenly attacks the thyroid gland, causing inflammation and damage to the gland. This leads to a decrease in thyroid hormone production, which is known as hypothyroidism (underactive thyroid).
 
Symptoms of Hashimoto's disease can vary, but may include fatigue, weight gain, sensitivity to cold, muscle weakness, joint and muscle pain, constipation, dry skin, hair loss, depression, and an enlarged thyroid gland (goiter). Some people with the condition may also experience heavy or irregular menstrual periods, or difficulty getting pregnant.
 
Hashimoto's disease is typically diagnosed through a combination of blood tests, physical examination, and sometimes imaging tests. The most common blood tests used to diagnose Hashimoto's disease include Thyroid-stimulating hormone (TSH) test, Thyroid peroxidase (TPO) antibodies test, and Thyroglobulin antibodies test.
 
The primary treatment for Hashimoto's disease is hormone replacement therapy, which replaces the thyroid hormone that the body is not producing enough of. It's important to work closely with a healthcare provider to find the right treatment plan and to monitor the condition regularly.
 
What are Hashimoto’s Disease symptoms?

The symptoms of Hashimoto's disease can vary but may include:

  • Fatigue
  • Weight gain
  • Cold intolerance
  • Muscle weakness
  • Joint and muscle pain
  • Constipation
  • Dry skin
  • Hair loss
  • Depression
  • Enlarged thyroid gland (goiter)
  • Heavy or irregular menstrual periods
  • Difficulty getting pregnant.

Symptoms can develop slowly over time and may not be noticeable at first. Some people may have no symptoms at all, and the condition is often diagnosed during routine blood tests. In some cases, symptoms may also be mistaken for symptoms of other conditions, making it difficult to diagnose.

It is important to see a doctor if you suspect you may have Hashimoto's disease, as an early diagnosis and treatment can help prevent complications and manage symptoms.

What triggers Hashimoto’s disease?
Hashimoto's disease is an autoimmune disorder. This means that the immune system mistakenly attacks the thyroid gland, leading to inflammation and damage to the gland. Genetic factors, hormonal imbalances, and exposure to certain toxins may also play a role in the development of the disease.

What does Hashimoto’s disease do to your body?

The immune system mistakenly attacks the thyroid gland, leading to inflammation and damage to the gland. This can cause the thyroid gland to become underactive (hypothyroidism), which can lead to a wide range of symptoms such as:

  • Fatigue
  • Weight gain
  • Cold intolerance
  • Constipation
  • Dry skin
  • Hair loss
  • Depression
  • Joint and muscle pain
  • Irregular menstrual cycles in women
  • Infertility

As the thyroid gland is responsible for producing hormones that regulate the body's metabolism, an underactive thyroid can cause the metabolism to slow down, leading to weight gain and sluggishness. It can also affect heart rate, body temperature, and digestion. In addition, untreated hypothyroidism can lead to other health problems such as high cholesterol, heart disease, and infertility. It is important to get diagnosed and treated as soon as possible to minimize the risk of complications and to manage symptoms.

What is the difference between Hashimoto’s disease and hypothyroidism?

Hashimoto's disease and hypothyroidism are related but distinct conditions. Hashimoto's disease is an autoimmune disorder that affects the thyroid gland, while hypothyroidism is a condition in which the thyroid gland is not producing enough thyroid hormones.

Hashimoto's disease is characterized by inflammation and damage to the thyroid gland, which leads to a decrease in thyroid hormone production. This decrease in thyroid hormone production is called hypothyroidism. Hashimoto's disease is the most common cause of hypothyroidism.

Symptoms of Hashimoto's disease and hypothyroidism are similar and may include fatigue, weight gain, sensitivity to cold, muscle weakness, joint and muscle pain, constipation, dry skin, hair loss, depression, and an enlarged thyroid gland (goiter).

Hashimoto's disease is typically diagnosed through a combination of blood tests, physical examination, and sometimes imaging tests. The most common blood tests used to diagnose Hashimoto's disease include the TSH test, the TPO antibodies test, and the thyroglobulin antibodies test.

Hypothyroidism can be caused by other conditions as well, such as congenital hypothyroidism, radiation treatment, surgery, and certain medications.

Treatment for both Hashimoto's disease and hypothyroidism is hormone replacement therapy, which replaces the thyroid hormone that the body is not producing enough of. It is important to work closely with a healthcare provider to find the right treatment plan and to monitor the condition regularly.

Can you have Hashimoto’s disease without a thyroid?
Hashimoto's disease is an autoimmune disorder that affects the thyroid gland, and it is typically characterized by inflammation and damage to the gland. In some cases, inflammation and damage can lead to the destruction of the thyroid gland, resulting in the absence of a functioning thyroid gland. When this happens, it is called "atrophic thyroiditis" and it is considered a form of hypothyroidism (low thyroid function) caused by Hashimoto's disease. In this case, the person would not have a functioning thyroid gland, and would require lifelong hormone replacement therapy to maintain normal levels of thyroid hormones in the body. It is important to note that the diagnosis of Hashimoto's disease is often made based on the presence of antibodies (TPO, TgAb) and other clinical signs and symptoms, rather than the presence or absence of a functional thyroid gland.

What is the best treatment for Hashimoto’s disease?

The best treatment for Hashimoto's disease is the replacement of the thyroid hormones that the body is not producing enough of. The most common treatment is levothyroxine, a synthetic form of the thyroid hormone thyroxine. This medication is taken daily, usually in the morning, and it helps to regulate the levels of thyroid hormones in the body, relieving symptoms and preventing complications. It is important to collaborate closely with an endocrinologist to find the right dosage of the medication, as it needs to be adjusted periodically. Blood tests will be performed regularly to monitor the levels of thyroid hormones and TSH (thyroid-stimulating hormone) in the blood and adjust the dosage accordingly.

In addition to hormone replacement therapy, lifestyle changes can also help manage symptoms of Hashimoto's disease. This includes eating a healthy and well-balanced diet, getting regular exercise, and managing stress. It is also important to avoid exposure to toxins and environmental triggers that may worsen symptoms and to avoid medications that may interact with levothyroxine.

For some people with Hashimoto's disease, in addition to levothyroxine therapy, other medications such as immunosuppressants or immunomodulatory therapy may be needed to help control the autoimmune process. It is important to note that treatment may not always be successful in reversing the autoimmune process, but the goal is to keep the thyroid functioning as best as possible and manage symptoms.

Can Hashimoto’s disease be reversed?

Hashimoto's disease is a chronic condition and once the damage to the thyroid gland has occurred, it cannot be reversed. However, the symptoms can be managed, and the progression of the disease can be slowed down.

The most common treatment for Hashimoto's disease is hormone replacement therapy with levothyroxine, which helps to regulate the levels of thyroid hormones in the body and relieve symptoms. This medication needs to be taken lifelong and the dosage needs to be adjusted periodically based on blood test results.

In addition to hormone replacement therapy, lifestyle changes such as eating a healthy and well-balanced diet, getting regular exercise, and managing stress can also help manage symptoms. Avoiding exposure to toxins and environmental triggers that may worsen symptoms and avoiding medications that may interact with levothyroxine is also important.

For some people with Hashimoto's disease, in addition to levothyroxine therapy, other medications such as immunosuppressants or immunomodulatory therapy may be needed to help control the autoimmune process. It is important to note that treatment may not always be successful in reversing the autoimmune process, but the goal is to keep the thyroid functioning as best as possible and manage symptoms.

It is important to work closely with an endocrinologist to monitor the disease and adjust the treatment plan accordingly.

What causes Hashimoto’s Disease?

The exact cause of Hashimoto's disease is not fully understood. However, it is believed to be caused by a combination of genetic and environmental factors.
Genetics: Hashimoto's disease tends to run in families, which suggests that there may be a genetic component to the condition. Research has identified several genes that may be associated with an increased risk of developing Hashimoto's disease.

Environmental factors: Certain environmental factors, such as exposure to radiation and certain viruses or bacteria, have been linked to an increased risk of developing Hashimoto's disease. Additionally, imbalances in the immune system, such as chronic inflammation, can also increase the risk of Hashimoto's disease.

Autoimmunity: Hashimoto's disease is an autoimmune disorder, which means that the body's immune system mistakenly attacks the thyroid gland. It is believed that a combination of genetic and environmental factors may trigger the development of Hashimoto's disease by causing the immune system to attack the thyroid gland.

It's important to note that the cause of Hashimoto's disease can vary from person to person, and in some cases, the exact cause may not be known.

How is Hashimoto’s Disease diagnosed?

Hashimoto's disease is usually diagnosed through a combination of blood tests, physical examination, and sometimes imaging tests. The most common blood tests used to diagnose Hashimoto's disease include:

  • Thyroid-stimulating hormone (TSH) test: This test measures the level of TSH in the blood. People with Hashimoto's disease typically have an elevated level of TSH and a low level of thyroid hormones, such as T4 and T3.
  • Thyroid peroxidase (TPO) antibodies test: This test measures the level of TPO antibodies in the blood. People with Hashimoto's disease typically have elevated levels of these antibodies.
  • Thyroglobulin antibodies test: This test measures the level of thyroglobulin antibodies in the blood. People with Hashimoto's disease typically have elevated levels of these antibodies.

Physical examination such as feeling the thyroid gland to see if it is enlarged, and imaging tests such as ultrasound of the thyroid can also aid in diagnosis. A doctor may also evaluate the patient's medical history, family history, and symptoms to arrive at a diagnosis.

It is important to note that Hashimoto's disease can sometimes be difficult to diagnose, as the symptoms can be like other conditions, and the blood test results may not always be definitive. If you have symptoms that suggest Hashimoto's disease, it's important to see a doctor for a proper diagnosis and treatment.

How serious is Hashimoto’s disease?
Hashimoto's disease is a chronic condition that can lead to damage of the thyroid gland, which can cause the gland to become underactive (hypothyroidism). This can cause a wide range of symptoms, including fatigue, weight gain, cold intolerance, hair loss, and depression. If left untreated, Hashimoto's disease can lead to an enlarged thyroid gland (goiter) and, in rare cases, thyroid cancer. In addition, untreated hypothyroidism can lead to other health problems such as high cholesterol, heart disease, and infertility. It is important to get diagnosed and treated as soon as possible to minimize the risk of complications and to manage symptoms. Treatment typically involves taking a daily thyroid hormone replacement medication to help regulate the levels of thyroid hormones in the body.
