Thyroid nodules are caused by abnormal growth of the thyroid gland, and neither food nor medication can reduce the size of thyroid nodules. There are benign and malignant thyroid nodules. Benign nodules that are small in size and do not cause clinical symptoms can be left untreated with regular checkups. Patients with large nodules or malignant nodules that have affected breathing and swallowing functions should consider going to the hospital for treatment: 1. Western medicine treatment: patients with thyroid nodules often experience symptoms such as irritability, excessive sweating, weight loss, and panic attacks, etc., and can take antithyroid drugs such as propylthiouracil and methylthioimidazole as prescribed by the doctor for treatment; 2. Traditional Chinese Medicine (TCM) treatment: TCM practitioners believe that Chinese medicines like Xia Kucai Cao (夏枯草), Cat’s Claw Cao (猫爪草), Oyster, and Turtle shells (鳖甲) have the ability to eliminate stasis and dissipate lumps and lumps. Chinese herbal medicine has the effect of eliminating blood stasis and dispersing nodules, but there are fewer clinical studies, so patients can go to the hospital for appropriate diagnosis and treatment. 3, Surgery: patients with large thyroid nodules or those who have already affected their daily life need to consider surgical removal of the thyroid gland, and at present, thyroid surgeries include total thyroidectomy, unilateral thyroidectomy, and lumpectomy, which will be performed by a surgeon according to the severity of the patient’s thyroid nodules. The doctor will formulate a surgical plan according to the severity of the patient’s thyroid nodules. 4. Daily management: Iodine deficiency is an important reason for the formation of thyroid nodules, and patients who do not have hyperthyroidism can consume foods with high iodine content such as kelp, marine fish, and purslane, in order to prevent the volume of thyroid nodules from becoming larger. In addition, long-term radiation stimulation may also lead to an increase in the size of thyroid nodules, patients should reduce the time to play cell phones and computers, away from electromagnetic radiation, to reduce the risk of disease exacerbation.
