Usually, there is no apparent cause of a hernia , although it is commonly thought to be the result of lifting a heavy object. A hernia occurs when part of an organ protrudes through a weak point or tear in the thin muscular wall that holds the abdominal organs in place. In men, a hernia can develop at the point where the spermatic cord passes out of the abdomen into the scrotum . A direct inguinal hernia creates a bulge in the groin area, and an indirect hernia descends into the scrotum.
Inguinal hernias occur less often in women than men.
The mass may increase in size when coughing, bending, lifting, or straining. An inguinal hernia can often be pushed back into the abdominal cavity. However, if it cannot be forced back through the abdominal wall, the herniated bowel may become trapped in the inguinal ring or strangulated. Without treatment, the strangulated loop of intestine dies, because its blood supply is compromised. Surgery to reposition the loop of intestine and secure the weakened muscles in the abdomen is usually indicated.
