Does obesity increase inguinal hernias?

Is the prevalence of hernia a result of the prevalence of obesity effecting the recurrence rate? Figure 1 represents an inguinal hernia protuised through a defective inguinal canal obtained from: http://www.mayoclinic.org/diseases-conditions/inguinal-hernia/home/ovc-20206354 Abstract- The prevalence of hernias is greater in obesity. Obesity is suspected to impact the success rate of inguinal hernia repairs as the recurrence rate is higher. The higher recurrence rate was identified as a result of surgical and postoperative complications affecting the success rate of surgery. Certain factors decrease how successful the surgery is and increase the risk of a recurrence. Factors such as surgical complications and post-operative complications and surgical procedure type reduce the success rate. The aim is to investigation the impact of obesity on the success rate of inguinal hernia repair, by identifying the amount of recurrences, surgical and postoperative complications.
