Abdomen is the favorite target spot where the maximum numbers of hernias like to develop. If the abdominal wall is not strong enough and has some kind of a weakness, it can evolve into a rupture or defect or hole that is localized. Through this orifice or rupture abdominal organs and adipose tissue may push through and bulge out. Peritoneum is the covering of the abdominal organs.
There is also another kind of hernia that is commonly seen and which results in sciatica or back pain. It is called intervertebral disc hernia.
Pathophysiology - Symptoms of hernia
The patient suffering from hernia may or may not experience pain in the afflicted portion. There might be a palpable or visible swelling or protrusion or lump which is caused by the contents of the hernial sac.
Some hernias are not accompanied by symptoms or even if there are symptoms they are so mild that they can’t be felt by the patient. In such cases usually the hernia is accidentally detected by the doctor while conducting a routine annual check up.
Sometime the symptoms will be very vague and issue from the pressure created on a particular organ when it gets herniated. At times organ dysfunction can result from this. However it is the fatty tissue which will first get herniated followed by the organ.
When pressure inside the residing organ compartment increases a lot, it leads to hernia. This can happen also because of the weakened boundary wall.
That is why doctors always advise hernia patients not to put pressure on their abdominal muscles if they suffer from or run a risk of developing abdominal hernia.
Intra abdominal pressure can get chronically aggravated because of benign prostatic hypertrophy, dyschezia, COPD, ascites or pregnancy. There is also another kind of hernia called intracranial hernia that takes place in the brain.
