An abdominal hernia occurs when there is a hole, tear or weak spot in the muscle wall, allowing intestine or other organ or, in some cases, fat to bulge through.
If a hernia disappears upon lying down, it is considered reducible.
If does not disappear, it is non-reducible.
A hernia can either be Congenital (a problem that you are born with) or acquired (develops because of a weakness in the tissues or from an injury).
Types of Hernia
There can be many forms of hernia but usually we encounter 5 types of hernia in majority of the patients.
- Inguinal Hernia
- Epigastric Hernia
- Ventral Incisional Hernia or Ventral Hernia
- Umbilical Hernia
- Femoral Hernia
- About 75% of abdominal wall hernia are inguinal
- Occur in the groin, which is the area between your abdomen and thigh.
- The contents of the abdomen – namely the intestine – protrude through a tear in the abdominal wall muscle creating a visible bulge and sometimes pain.
- Occur between the lower part of the breastbone and the naval
- Caused by a weakness or opening in the fibrous tissue of the abdomen.
- This type of hernia usually consists of fatty tissue and rarely contains intestinal tissue
- Sometimes causes a great deal of pain.
Ventral Incisional Hernia or Ventral Hernia
- Occur in the abdomen in the area of any prior surgical incision or scar.
- Hernias of this type are often accompanied by a swelling or bulge near the area of the prior incision,
- Can occur in 10-15% of abdominal surgeries especially in contaminated surgeries or in obese people
- Pain may be an early warning sign of an incisional hernia, as there may not be any initial presence of a bulge.
- Occur in or around the naval, or umbilicus.
- May be present by birth
- Occur in adults due to repeated strain or stress on the abdominal muscles.
- Femoral hernias are almost exactly the same as inguinal hernias.
- Occurs when abdominal contents are forced through the “femoral canal”. Caused by a weakness or opening in the fibrous tissue of the abdomen.
- This type of hernia occurs in an area just lower than the more common inguinal hernia.
- Females are more prone to these types of hernias as opposed to men
