How long it takes for thymoma to return to normal after surgery usually depends on the operation method, and the general recovery time is about 1~3 months, in addition, it is also related to the physical condition. 1. Surgical method: if patients with thymoma undergo minimally invasive thoracoscopic surgery, they can be discharged from the hospital about 1 week after the surgery. After going home, they can take sufficient rest and eat more protein-rich food to help the wound healing, and the patient can basically return to normal in about 1 month. If the patient is treated with open heart surgery, because the surgical wound is larger, so the recovery time is longer, usually need to be discharged from the hospital after two weeks after the operation, and need to go home and rest for about 3 months before they can return to normal. 2. Physical status: if the patient has diabetes, tumor and other basic diseases, the recovery time will be prolonged, it is recommended to increase nutritional intake, pay attention to wound cleaning and hygiene, pay more attention to rest, and have regular recheck. It is recommended that patients with thymoma should go to regular hospitals and listen to the advice of professional doctors.
