Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is a common type of autoimmune thyroid disease and the main cause of primary hypothyroidism. Often, Hashimoto's thyroiditis may present no symptoms, having hidden onset and slow development. Typical symptoms include general fatigue, throat discomfort, localized pressure, or dull pain. Hashimoto's thyroiditis can lead to damage by the autoimmune system, causing permanent hypothyroidism. Diagnosis can be facilitated through thyroid function tests, iodine-131 uptake tests, anti-thyroid antibody tests, thyroid ultrasound, and thyroid nuclear scanning.

Is Hashimoto's thyroiditis contagious?

Hashimoto's thyroiditis is an autoimmune disease, which is neither hereditary nor contagious, but it does tend to run in families. If parents have Hashimoto's thyroiditis, their children are at a relatively higher risk of developing the disease. Therefore, Hashimoto's thyroiditis is not contagious, so everyone can be reassured. As for the treatment of Hashimoto's thyroiditis, if hypothyroidism occurs, one simply needs to take levothyroxine on time for replacement therapy to restore thyroid function to normal levels without any special discomfort. When the thyroid gland in Hashimoto's thyroiditis is relatively large and causes significant compression symptoms, surgical treatment can be considered. Therefore, Hashimoto's thyroiditis is not contagious, nor is it hereditary, but it does have a familial clustering tendency.

What are the symptoms of Hashimoto's thyroiditis?

Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is an autoimmune disease. Its main manifestation includes possible enlargement of the thyroid in some people. If Hashimoto's thyroiditis is accompanied by hypothyroidism, symptoms may include general fatigue, constipation, bradycardia, and edema. If these symptoms are present, it is important to visit an endocrinology specialist promptly for further thyroid function tests, thyroid ultrasonography, thyroid peroxidase antibody tests, and other examinations to confirm the diagnosis.

How is Hashimoto's thyroiditis treated?

Hashimoto's thyroiditis is a chronic autoimmune disease and is the most common form of thyroid inflammation clinically. It can be diagnosed through thyroid function tests, iodine-131 uptake tests, thyroid antibody tests, and ultrasound examinations. If there are changes in imaging or if serum anti-thyroglobulin antibodies and anti-thyroperoxidase antibodies are positive, a diagnosis can be confirmed. Regarding treatment, if thyroid function is normal in Hashimoto's thyroiditis, no treatment is necessary, but close monitoring and observation are advised. If Hashimoto's thyroiditis is accompanied by transient hyperthyroidism, symptomatic treatment with beta-blockers can be administered. If there is a decrease in thyroid gland function, thyroid hormone replacement therapy should be initiated, typically with levothyroxine tablets, until thyroid function tests return to normal. Additionally, daily care is important, such as avoiding high doses of iodine intake, maintaining regular sleep patterns, avoiding staying up late, maintaining a positive and optimistic mood, avoiding anxiety and stress, preventing common cold and trauma infections, and ensuring a balanced diet with high protein, low fat, high carbohydrate, and high vitamin content.

Is Hashimoto's thyroiditis severe?

Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is a common type of autoimmune thyroid disease. Hashimoto's thyroiditis is the most common cause of hypothyroidism. If hypothyroidism caused by Hashimoto's thyroiditis is identified, long-term administration of levothyroxine can achieve good control. It is worth noting that the clinical manifestations of Hashimoto's thyroiditis are often atypical, or may coexist with other thyroid diseases, or other autoimmune diseases. Special attention needs to be paid to certain types of Hashimoto's thyroiditis. One such type is Hashitoxicosis, Hashimoto's pseudohyperthyroidism, or Hashimoto's thyroiditis accompanied by thyroid tumors, Hashimoto's encephalopathy, or Hashimoto's with proptosis. These special types require particular attention.
