Prevention of an incisional hernia depends on a number of factors. Surgeons are expected to use effective surgical techniques to minimize complications. Patients must follow discharge instructions to avoid contaminating their surgical wound. For the most part, developing a wound infection may increase the risk of an incision hernia. Furthermore, patients are advised to limit and/or avoid activities that put pressure on the incision.
 
The following preventative measures may help to decrease a complication of surgery such as an incisional hernia: 
Avoid overexertion
Treat constipation to avoid straining
Use precaution when coughing and sneezing
Limit activity that increases pressure on surgical wound
Use of prescribed gels that may promote healthy wound healing (ask about this gel).
Reduce and/or avoid sexual activity until wound heals.
Reduce and/or eliminate smoking

It is important to note that age and physical health may have a direct impact on postoperative care. There is no guarantee in preventing an incisional hernia following surgery, though patients can take preventative measures to reduce these potential risk factors.
