Like other general surgeries, papillary thyroid cancer must control diet, blood sugar, blood pressure, relax the mind and prepare for surgery in advance. 1. Surgery for papillary thyroid cancer usually requires general anesthesia, so patients should not eat foods that irritate the pharynx, such as chili peppers, garlic, etc., and eat high quality protein, such as fish, shrimp, etc., for a period of time before surgery. Strictly forbid food and water on the day before surgery. 2. You can practice the post-surgical state in advance, such as decubitus position to avoid postoperative neck discomfort; practice using urinal and so on. 3. If you suffer from high blood pressure or diabetes, you must use hypoglycemic and antihypertensive drugs under the guidance of your doctor to avoid affecting the operation. In conclusion, before papillary thyroid cancer surgery, we should strictly follow the doctor’s instruction to avoid accidents during the surgery.
