What are the three main classifications of thyroid diseases?

Euthyroidism, hyperthyroidism, and hypothyroidism, clinical states reflecting normal, excessive, or defective levels of thyroid hormones, were the basis of classification (1, 2).

What is the classification of Hashimoto’s thyroiditis?

Background: Hashimoto’s thyroiditis (HT) is a common organ-specific autoimmune disease. Antithyroglobulin antibodies (TgAb) and antithyroperoxidase antibodies (TPOAb), predominantly of the immunoglobulin (Ig) G class, are hallmarks of HT. It has been reported that HT can be divided into IgG4 and non-IgG4 thyroiditis.

What is the classification of Graves disease?

Graves disease, along with Hashimoto thyroiditis, is classified as an autoimmune thyroid disorder.

What is the cause of thyroiditis?

Thyroiditis is caused by an attack on the thyroid, causing inflammation and damage to the thyroid cells. Antibodies that attack the thyroid cause most types of thyroiditis. As such, thyroiditis is often an autoimmune disease, like juvenile (type 1) diabetes and rheumatoid arthritis.

What is subacute thyroiditis?

Definition. Subacute thyroiditis is an immune reaction of the thyroid gland that often follows an upper respiratory infection. The thyroid gland is located in the neck, just above where your collarbones meet in the middle.

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

Like Hashimoto’s disease, Graves’ is also an autoimmune disorder affecting the thyroid. The difference between the two is the type of antibodies your immune system attacks the thyroid with and how the attack impacts the thyroid. Hashimoto’s disease causes hypothyroidism, whereas Graves’ disease causes hyperthyroidism.

What are the types of hyperthyroidism?

There are several forms of hyperthyroidism, including:
  • Graves’ disease (diffuse toxic goiter). Graves’ disease is the most common cause of hyperthyroidism. …
  • Toxic nodular goiter (also called multinodular goiter). …
  • Thyroiditis.

What’s the difference between hypothyroidism and hyperthyroidism?

Hyperthyroidism is an overactive thyroid (when it produces too much thyroid hormone). Hypothyroidism is an underactive thyroid (when it does not produce enough). Hypothyroidism is more common than hyperthyroidism. Although the two conditions have different signs and symptoms, sometimes they overlap.

What are the types of hyperthyroidism?

There are several forms of hyperthyroidism, including:
  • Graves’ disease (diffuse toxic goiter). Graves’ disease is the most common cause of hyperthyroidism. …
  • Toxic nodular goiter (also called multinodular goiter). …
  • Thyroiditis.

What are early warning signs of thyroid problems?

7 Early Warning Signs of Thyroid Issues
  • Fatigue.
  • Weight gain.
  • Weight loss.
  • Slowed heart rate.
  • Increased heart rate.
  • Sensitivity to heat.
  • Sensitivity to cold.

What is the difference between primary and secondary hyperthyroidism?

Primary hyperthyroidism is the term used when the pathology is within the thyroid gland. Secondary hyperthyroidism is the term used when the thyroid gland is stimulated by excessive thyroid-stimulating hormone (TSH) in the circulation.

What level of TSH indicates hyperthyroidism?

A low TSH level—below 0.4 mU/L—indicates an overactive thyroid, also known as hyperthyroidism. This means your body is producing an excess amount of thyroid hormone. What causes high TSH levels? A high TSH level—above 4.5 mU/L—indicates an underactive thyroid, also known as hypothyroidism.

What is difference between thyrotoxicosis and hyperthyroidism?

Hyperthyroidism is characterised by increased thyroid hormone synthesis and secretion from the thyroid gland, whereas thyrotoxicosis refers to the clinical syndrome of excess circulating thyroid hormones, irrespective of the source.

What is the most common cause of hyperthyroidism?

Graves disease (most common cause of hyperthyroidism) Inflammation (thyroiditis) of the thyroid due to viral infections, some medicines, or after pregnancy (common) Taking too much thyroid hormone (common) Noncancerous growths of the thyroid gland or pituitary gland (rare)

What is the best medicine for hyperthyroidism?

Medicines called thionamides are commonly used to treat an overactive thyroid. They stop your thyroid producing excess hormones. The main types used are carbimazole and propylthiouracil. You’ll usually need to take the medicine for 1 to 2 months before you notice any benefit.
