If your procedure was performed with IV sedation or general anesthesia, you should initially only drink liquids following your procedure. Drink from a glass and avoid straws, as the sucking motion used to drink from a straw can dislodge the blood clot and cause more bleeding.
Feel free to start eating soft foods, but try to avoid chewing near the surgical sites. A high protein, high calorie diet is important, and you should be sure to get nourishment regularly. Drinking water consistently is also important in order to prevent dehydration, especially since you likely won’t be eating very much for the first few days.
Do the best that you can to not skip meals. If you continue to eat, you'll feel better, heal faster, and will have more strength.
