Any abnormal bulge in the body which increases on coughing/ straining or reduces in size on lying down clearly indicates a hernia. It is commonly seen in groin region (lnguinal & femoral), abdominal or previous surgical sites.
Abdominal Hernia is like a bag which can contain intestine / abdominal organ. There is always a risk of the intestine getting trapped there and become strangulated requiring unnecessary removal of normal intestine.
If timed properly, this hernia surgery can be accomplished with placement of barriers ( Mesh/ Jali) which prevents recurrence. Fortunately,almost all the hernia surgeries can now be performed with the technology of laparoscopy avoiding big cuts and which also reduces risk of infection/ failure of surgery.
