Mild excercises can be started. Excercises which involve lifting weights, or applying pressure Should be avoided. But simple brisk walk can b started and running etc can be started gradually progressing.

Was it an open surgery or a laparoscopic surgery (key hole)?

Hi If you have undergone a open surgery for gall bladder removal, then it's better to follow your surgeon's advice after keeping a regular follow up with him. Observations about wound are very important. Generally we start regular gentle exercises after a month and weight lifting after a year to avoid hernia formation. Keep in touch with your surgeon.
