A hernia is a sac formed by the lining of the abdominal cavity (peritoneum). The sac comes through a hole or weak area in the strong layer of the belly wall that surrounds the muscle. This layer is called the fascia. More details about hernia are here: http://www.zdrav.kz/en/node/9826
If you aren't able to push the hernia in, the contents of the hernia can be trapped (incarcerated) in the abdominal wall. An incarcerated hernia can become strangulated, which cuts off the blood flow to the tissue that's trapped. A strangulated hernia can be life-threatening if it isn't treated.
Signs and symptoms of a strangulated hernia include:
- Nausea, vomiting or both
- Sudden pain that quickly intensifies
- A hernia bulge that turns red, purple or dark
- Inability to move your bowels or pass gas
If any of these signs or symptoms occurs, call your doctor right away.
