Due to the short hospital stay after thyroid surgery, often 2-3 days after surgery, you may not be able to communicate with your doctor during this period, I believe the following can solve some of your confusion. 1.Wound care: Generally the day of extraction or the next day of discharge, the drainage tube mouth may not yet heal, there will be a small amount of exudate, this is normal, if wet dressing, you need to change the medicine again. This is normal, and if the dressing is wet, it will need to be changed again. It usually heals in 1-2 days. Sometimes there will be fluid under the incision, bulging, this is not to worry, let the doctor fine needle puncture drainage, usually 1 time can solve the problem. The wound is initially like a thin red line, the surrounding tissue will be somewhat edematous, and there will be a pulling sensation in the neck when swallowing, which are all normal steps in the wound healing process. Generally, after 1 week, if the incision does not ooze, it can be flushed with water. The neck pulling sensation will be relieved when the tissue scar is softened, which will take 3-6 months, and more than 1 year for those with special constitution. 2.Taking of medication: Usually the doctor will care to take medication such as Eugenol when discharged from the hospital. This drug should be taken in the morning in the state of fasting the full dose of the day, and eat breakfast about half an hour after taking the drug, so that the side effects of the drug can be minimized and the best efficacy. Beginners sometimes forget, so take the medicine at the first sign of remembering. The main side effects of the drug are headache, heartburn and high blood pressure. However, long-term use of thyroxine preparations will not cause adverse effects on the body as long as the thyroid function is checked regularly and the dosage is appropriate. In addition, if there are patients with numbness in the hands and feet, they should be treated seriously with calcium supplementation. 3, review time: generally 2 weeks after discharge, let the doctor know about the incision healing and medication. The thyroid function should be checked once every 6 weeks at the beginning of the medication, and if it is stable, the time will be extended later. The ultrasound should be reviewed 3 months after surgery. 4, diet: this issue is more divergent, generally western medicine will not have a lot of taboos, such as eggs, chicken, pigeons, fish, soy sauce, etc.. There is also the concern of iodized salt and foods containing high iodine, such as kelp, seaweed, nori, etc.. There are reports in the literature that high iodine can cause nodule growth. Since we are located in an iodine-rich region and are not deficient in iodine, we should not consume too much of these foods. In addition, a small number of scholars have found that excessive smoking and alcohol consumption may contribute to the development of nodules.
