Elimination of thyroid nodules can be solved by diet and medical means. Thyroid nodules are multiple lumps in the thyroid gland in the body, which are usually benign. It will move up and down with swallowing movements, causing much inconvenience to a person’s life and recurring attacks. Patients should first control their diet, protein and carbohydrates should be sufficient, iodine intake should be controlled in coastal areas, while avoiding tobacco, alcohol and spicy food, and develop good habits in life. Benign thyroid nodules can also be treated with sclerotherapy or radiofrequency ablation, by ultrasound-guided injection of anhydrous ethanol at the nodule until the nodule disappears. The problem of thyroid nodules can be solved surgically, with surgical excision and endoscopic removal.
