You can eat some lychee in small amounts after surgery and wait until you are able to eat as prescribed by your doctor. It is recommended to maintain a good diet after surgery to help your body recover as soon as possible. Lychee contains some vitamin C, amino acids and other nutrients, so you can eat a small amount of lychee after resuming a normal diet (e.g., you can eat noodles and rice). However, lychee belongs to the food that can easily cause the body to be on fire, and excessive consumption may induce wound infection, so it is not recommended to consume a large amount of it, so as not to affect the postoperative recovery. After the surgery, you should avoid eating cold, spicy and stimulating foods, such as hot pot and chili peppers, otherwise it may stimulate the wound healing and affect the therapeutic effect, and you should also try to avoid eating seafood or overly sweet foods, so as not to increase the burden on the intestinal tract. You can eat some protein-rich foods, such as eggs, lean meat and so on.
