What are the weak points in the abdominal cavity?

Right and left groin: The weak spots in the muscular abdominal wall are at the right and left groin. With repeated pressure, persistent pressure, and increasing age, a person becomes more likely to get a hernia at one or both weak spots. A hernia bulging outwards is a "direct" hernia (more in older people), and one that points downward into the scrotum (men) or labia majora (women; uncommon) is an "indirect hernia".

Congenital or surgic: Esophgeal hiatus, umbilicus, prior surgical incisions, inguinal ring, sites of a spigelean, diaphragmatic and/or and richter's hernias.

Hernias: Weak points in the anatomy are the reason patients have hernias. The most common place is the inguinal/groin region. Next is the umbilicus/belly button and femoral hernias. Other placed are at abdominal wall incisions from previous surgeries, the esophageal hiatus in the diaphragm/hiatal hernias, or spigelian hernias less commonly in the lateral abdominal wall.
