Hernia occurs due to the abdominal wall bulging. When abdominal pressure increases, the abdominal muscles tend to tighten, causing the abdominal wall to strain or bulge out.
The following factors often increase intra-abdominal pressure and cause a hernia: obesity, weight bearing, coughing, bowel movement straining, constipation, diarrhea, chronic lung diseases. The common hernia types include: groin hernia, femoral hernia and umbilical hernia.
Depending on the hernia severity, the symptoms may include: painless lump, abdominal pain, bowel obstruction, nausea, vomiting, strangulated intestine, fever. The patient should avoid any aggravating activities, and seek necessary medical help.
