Advice from medical staff of Puding Friendship Hernia Hospital: Generally, strenuous exercise should not be done within three months after hernia operation. To put it simply: hernia, commonly known as intestinal leakage, will leak after strenuous exercise before operation. Now, after the operation, you can only do strenuous exercise when your body recovers. Three months is still in the case of good physical recovery, and if the physical recovery is not good, the time will be slightly longer! I hope I can help you!
