The main reason of this disease is the weakening of muscular walls. If this disease is common in the family history, then chances are high that a family member is going to be affected by hernia. Children in poor conditions may even suffer from hernia because of absence of certain essential nutrients. It is an extremely painful disease when organs such as intestines bulge out from the abdominal wall.
Some conditions such as pregnancy or dyschezia cause intra-abdominal pressures to increase, hence the risk of abdominal hernia increases. This can even lead to increase in intracranial pressure that causes some parts of the brains to pass signals through the cranial cavity.
