After thyroid cancer surgery, you can usually start eating some fluids 6 hours after surgery, and then slowly transition to a general diet as appropriate. A low-fat diet with warm and cool foods is usually recommended. Some patients may also need to go on a low iodine diet for a period of time. 1. Low iodine diet: Patients who need iodine treatment need to eat a low iodine diet during the iodine treatment period, and after the iodine treatment is finished, they can eat a normal diet. 2. Low-fat diet: Try to have a low-fat diet within 2 weeks after thyroid cancer surgery, so as to reduce the risk of celiac disease formation after surgery. For example, you can consume more fresh vegetables and fruits such as carrots and peas. 3. Eat warm and cool foods: Consuming foods that are too warm may irritate the wound and cause discomfort. Consume milk, egg custard and other foods. Avoid spicy and stimulating diet.
