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.

Can Hashimoto's thyroiditis breastfeed?

Patients with Hashimoto's thyroiditis can breastfeed. It is important for those in a hyperthyroid phase, especially when taking anti-thyroid medications, to switch to breastfeeding-safe medications beforehand and to regularly monitor thyroid function to ensure it remains within normal limits. Patients in a hypothyroid phase should also regularly monitor their thyroid function and adjust their replacement medication dosage accordingly. Newborns should have their thyroid function and related antibodies regularly tested from birth onwards. (Please medicate under the guidance of a physician.)

Does Hashimoto's thyroiditis cause a sore throat?

Hashimoto's thyroiditis does not cause a sore throat; the type of thyroiditis that primarily causes a sore throat is subacute thyroiditis. Subacute thyroiditis is a viral infection and is a self-limiting disease. Its main clinical manifestations include sore throat, thyroid enlargement, as well as accompanying fever and elevated erythrocyte sedimentation rate. Meanwhile, Hashimoto's thyroiditis is an autoimmune disease, whose most common clinical manifestation is painless thyroid enlargement, progressing to hypothyroidism in later stages. Additionally, it involves thyroid antibodies, especially positive TPO antibodies. Because the treatments for each are different, it is important to note that Hashimoto's thyroiditis does not cause a sore throat.

Can Hashimoto's thyroiditis be cured?

Hashimoto's thyroiditis is an autoimmune thyroiditis where the body itself has autoantibodies that lead to the destruction of thyroid follicular cells, resulting in the failure of thyroid cells. Therefore, Hashimoto's thyroiditis can manifest as hyperthyroidism, euthyroidism, and hypothyroidism. Ultimately, Hashimoto's thyroiditis may develop into hypothyroidism. Hypothyroidism is proliferative and generally cannot be completely cured, but clinical remission can be achieved through oral administration of levothyroxine. However, Hashimoto's thyroiditis cannot be completely cured and requires lifelong replacement therapy.

What is the heart rate for Hashimoto's thyroiditis?

Hashimoto's thyroiditis is an autoimmune thyroid disease. The course of the disease can include hyperthyroidism, euthyroidism, and hypothyroidism. When Hashimoto's thyroiditis is at different stages of thyroid function, the changes in heart rate are also inconsistent. When Hashimoto's thyroiditis coincides with hyperthyroidism, the heart rate may be fast, even exceeding 100bpm. When Hashimoto's thyroiditis coincides with normal thyroid function, the heart rate may be within the normal range, around 60bpm to 100bpm. When Hashimoto's thyroiditis coincides with hypothyroidism, the heart rate may slow down, possibly dropping below 60bpm. Therefore, in Hashimoto's thyroiditis, as the thyroid function varies, so does the heart rate.

Hashimoto's thyroiditis symptoms

In the early stages, when the autoimmune destruction from Hashimoto's thyroiditis is not particularly severe and does not cause either hyperthyroidism or hypothyroidism, there may be no symptoms at all. As the immune response intensifies and leads to increased destruction of thyroid cells, transient thyrotoxicosis can occur, resulting in symptoms such as heat intolerance, trembling hands, and palpitations. The duration of these symptoms is related to the severity of the destruction. Generally, symptomatic relief can be achieved by administering beta-blockers. In the later stages, when the destruction of thyroid function in Hashimoto's is exacerbated, leading to hypothyroidism, symptoms such as cold intolerance, fatigue, and hair loss may occur. (Medication should be used under the guidance of a professional doctor.)
