How long you need to recuperate from open heart surgery is specific to the individual’s medical condition and the type of surgery. A relatively minor surgery, such as an appendectomy, can be recovered in about 7 days. In the case of open laparotomy for tumors, it usually takes about 10-15 days and the recovery time will be longer. Compared with laparoscopic surgery, open surgery is more open, more traumatic and slower to recover, so it is recommended to rest for 1-4 weeks, depending on the surgery. It is best not to do strenuous exercise for 3 months after surgery. After surgery, you can properly eat high-protein foods and vitamin-rich vegetables, melons, etc. During this period, try to avoid fried, barbecued and smoked foods, ensure sufficient sleep every day and relax your body and mind.
