In clinical practice, after open abdominal surgery, it usually takes about three months to be able to participate in physical exercise, because the so-called open abdominal surgery is also the traditional open abdominal surgery, generally speaking, the surgical incision is relatively large, and it takes about three months for the tissue to heal completely, otherwise it is just scar healing in a short time. Especially in physical exercise will inevitably lead to a sharp increase in intra-abdominal pressure, in the intra-abdominal pressure when the tissue healing is not yet complete, it is entirely possible to make the abdominal wall incision split, serious will lead to abdominal incision hernia or even incision full layer split, so that in clinical practice, if the traditional open abdominal surgery is also open, generally at least three months, to be completely healed tissue, the incision firmly healed before engaging in Otherwise, when the intra-abdominal pressure rises sharply, there is a risk that an incisional hernia of the abdominal wall may occur and another surgery will be required.
