Generally, you can eat porridge when you have intestinal ventilation, which is relatively thin. It's best not to put oil, you can put a little salt. A few times.
During this period, it is best not to drink milk, bread and some fermented things, because these will all produce gas and eventually lead to bloating.
Generally, the stitches are removed 7-9 days after appendectomy. You can slowly add a small amount of minced meat and minced vegetables. In short, it should be soft, the food should not be too rough, not too greasy, and eat less many times.
Therefore, fasting after appendicitis surgery is more painful.
I wish you a speedy recovery.
