Knowra Hernia Hernia A hernia is the protrusion of an organ or tissue through an opening or weak area in the wall that normally contains it. Its symptoms and risks depend on its location and whether the protruding tissue becomes trapped or loses its blood supply.
Abdominal wall : The layers of muscle, fascia, and connective tissue that enclose and support the abdominal cavity. Weakness or openings in this wall allow many common abdominal hernias to protrude.
Inguinal hernia : A protrusion through a weak area in the lower abdominal wall near the inguinal canal. It is the most common type of abdominal wall hernia.
Intra-abdominal pressure : The pressure within the abdominal cavity, influenced by breathing, posture, and bodily strain. Repeated or sustained pressure can push tissue through a vulnerable wall.
Physical examination : Assessment of the body using inspection, touch, and other bedside techniques. A clinician may identify a bulge that appears with standing, coughing, or straining.
Diastasis recti : Widening between the two sides of the rectus abdominis muscles without a true fascial defect. It can resemble a midline hernia but does not involve tissue protruding through a hole.
Fascia : Connective tissue sheets that surround, separate, and support muscles and organs. Fascial strength helps contain abdominal contents and resist hernia formation.
Femoral hernia : A protrusion through the femoral canal below the inguinal ligament. Its narrow opening makes bowel trapping a particular concern.
Valsalva maneuver : A forced exhalation against a closed airway that raises pressure in the chest and abdomen. Coughing or straining can make a hernia bulge more apparent during examination.
Ultrasonography : Medical imaging that uses high-frequency sound waves to produce images of internal structures. It can help detect hernias when examination findings are uncertain.
Hydrocele : A fluid collection around a testicle, usually within the tunica vaginalis. It can cause scrotal swelling that may be confused with an inguinal hernia.
