Incisional hernias are most likely to occur in obese patients and pregnant women. A history of multiple abdominal surgeries may increase the risk of developing an incisional hernia. A patient who gains significant weight after abdominal surgery, becomes pregnant or participates in activities that increase abdominal pressure such as heavy lifting are more likely to develop an incisional hernia. The incision is weakest and most prone to developing a hernia while it is still healing.Incisional hernias may seem to appear and disappear, which is referred to as a reducible hernia. The hernia may not be noticeable unless the patient is involved in an activity that increases abdominal pressure such as coughing, sneezing, straining due to constipation or lifting heavy objects. Diagnosis of an Incisional Hernia is predominantly a clinical examination. To understand the complex anatomy of these hernias, a CT Scan maybe requested by your Surgeon.
