Hashimoto’s thyroiditis is often accompanied by hypothyroidism, which can lead to facial swelling. The treatment of facial swelling in Hashimoto’s thyroiditis can start with medication and lifestyle intervention. 1. Medication: Hashimoto’s thyroiditis is a chronic autoimmune inflammation of the thyroid gland. In the early stages of the disease, patients often have no obvious symptoms, but as the disease progresses, symptoms of hypothyroidism may appear, such as fear of cold, weight gain, face swelling, etc. The patient can take oral levothyroxine as prescribed by the doctor. Oral levothyroxine sodium tablets can be prescribed as replacement therapy to improve the symptoms of hypothyroidism. 2. Lifestyle intervention: Hashimoto’s thyroiditis may be associated with excess iodine, so patients should reduce the intake of iodine in their diet and avoid foods such as nori and seaweed. In addition, it is necessary to stop smoking and drinking, exercise properly and keep a good mood. Patients with Hashimoto’s thyroiditis are advised to have their thyroid function checked regularly and actively cooperate with the treatment.
