Hashimoto’s thyroid, which should be referred to here as Hashimoto’s thyroiditis, the main clinical manifestations include neck swelling, hypothyroidism and other symptoms, and a few patients may also have no obvious symptoms, so it is recommended to consult a doctor. The cause of Hashimoto’s thyroiditis is not clear, but is usually caused by a combination of genetic, immune, and environmental factors. It is often thought that the immune system produces autoantibodies that attack the body, causing the symptoms. The clinical manifestations of Hashimoto’s thyroiditis mainly include neck swelling and hypothyroidism. There may be discomfort in the anterior neck region, localized pain and tenderness, and in severe cases, pressure symptoms and difficulty breathing or swallowing. Most patients have changes in thyroid function, with mild hyperthyroidism in the early stages of the disease and hypothyroidism in the later stages. If you find that your thyroid gland has symptoms, it is recommended that you consult a doctor in a timely manner for examination and symptomatic treatment of the cause of the disease.
