You can eat a regular diet without any restrictions after surgery. This, of course, will be limited by other illnesses you may have, such as diabetes, heart disease and hypertension.
Here are some general tips:
On the first day eat small, light meals and liquids. Progress to a normal diet as tolerated.
Nausea and vomiting from anesthesia are not uncommon for 24 hours. If you feel nauseous, take clear liquids only. Call the office if nausea and vomiting persist for greater than 36 hours.
Do not take any alcoholic drinks for at least 24 hours and while you are taking narcotic pain killers such as Vicodin (hydrocodone) or Tylenol (acetaminophen) with codeine.
