A flank hernia is a type of hernia that occurs in the side of the abdomen, typically between the ribs and the hip (the “flank” area).
It develops when there is a weakness or defect in the muscles of the abdominal wall along the side, allowing fat or internal organs to push through and create a bulge.
Common causes
Flank hernias are less common than other hernias and are often related to:
- Previous surgery in the side or back (such as kidney or spine surgery)
- Trauma or injury to the area
- Muscle weakness or thinning over time
Symptoms
- A noticeable bulge on the side of the abdomen
- Pain or discomfort, especially with movement, coughing, or straining
- A feeling of weakness or pressure in the flank area
Why they can be complex
Flank hernias can be more challenging to treat because of their location near bones (ribs and pelvis) and important nerves. This often requires specialized surgical expertise, sometimes involving abdominal wall reconstruction.
