Lumbar Lordosis: Symptoms & Signs

Lumbar lordosis is the inward curve of the lumbar, or lower, spine in the lower back. A small degree of lordosis (inward curvature) is normal, but excessive lordosis can result from underlying disease and conditions of the spine.

Symptoms and signs of lumbar lordosis can include

  • an appearance of being swayback or having an abnormal posture with an arched lower spine,
  • the buttocks appearing more pronounced, or
  • having a large gap or arch between the lower back and a flat surface when lying on your back.

In some people, there can be discomfort and/or back pain or difficulty in moving certain directions.
