Multiple thyroid nodules are more likely to be benign. In specific circumstances, patients should go to the hospital for thyroid color ultrasound to determine the nature of thyroid nodules. If the edge of thyroid nodule is clear, the nodule volume is small, and the patient has no obvious symptoms, treatment can be omitted, but regular observation is required. If the boundary of the nodule is not clear and the score is above grade 4, the nodule will increase rapidly in a short period of time, and thyroid puncture surgery is required to specifically define the nature of the thyroid nodule. If it is a malignant thyroid nodule, it needs to be treated by surgical excision. In daily life, it is forbidden to eat spicy and stimulating food, eat more fresh fruits and vegetables, take more rest, do not stay up late, and ensure adequate sleep.
