Low Back & Pelvis

What It Is

Hyperlordosis is an exaggerated curve in the lumbar part of the spine (the lower back). The lower part of the back curves inward far more than it naturally should. It is sometimes called "swayback" (MedlinePlus, 2026). The spine needs a natural curve to work properly, and the inward curve of the lower back helps the spine cope with the load placed on it (Okpala, 2018). This is due largely to the shape of the individual spinal bones. If the curve becomes too great, the extra stress placed on other parts of the spine may cause pain (Okpala, 2018).

Some of the muscles around the spine and hip may become tight, while others become stretched and weak, causing an imbalance. Some therapists call this pattern "lower crossed syndrome": if you draw a line from the tight hip flexors to the tight lower back, and another from the weak hamstrings to the weak abdominals, the two lines form a cross. This is a way of describing muscle balance rather than a proven cause, and the research evidence for it is limited.

There Are a Number of Other Causes of an Increased Lordosis

  1. Children: some children have a marked lordosis that usually corrects itself as they grow. This is called benign juvenile lordosis (MedlinePlus, 2026).
  2. Spondylolisthesis: a condition where one of the spinal bones slips forward can cause an increased lordosis (MedlinePlus, 2026).
  3. Pregnancy: the increased weight at the front can pull the spine into an extended (lordotic) position.
  4. Excessive extending exercises and sports: some dance or gymnastics-related sports require a lot of arching (extension) through the spine, which can increase the lordosis.
  5. Rarer causes: in children, much less common causes include some genetic conditions that affect bone growth or the muscles (MedlinePlus, 2026).

Hyperlordosis Anatomy

The spine has a natural inward curvature, known as a lordosis, in the lower back and the neck. The normal size of the lower back curve varies widely from person to person, and the measured angle also depends on the method used to measure it, so there is no single "correct" number (Okpala, 2018). When the curve is larger than usual, it may be called a hyperlordosis.

Hyperlordosis can place stress on the posterior (back) structures of the spine, such as the facet joints (the small joints at the back of each spinal bone). These joints may become inflamed and, in time, arthritic (facet joint arthritis, a type of spondylosis). This can cause pain in the lower back.

Hyperlordosis is also linked with a condition called spondylolisthesis (where one vertebra slips forward compared with the vertebra below). Spondylolisthesis can itself cause an increased lordosis (MedlinePlus, 2026). In young athletes and gymnasts, repeated arching of the back can cause a tiny crack (stress fracture) in a spinal bone, which can lead to spondylolisthesis (NHS, 2026). Spondylolisthesis can cause lower back pain, tight hamstrings, and pain, numbness or tingling down one leg (sciatica) (NHS, 2026).

So it is important to know that a normal spine has a lordosis in the lower back and in the neck. But when this lordosis is exaggerated, it might be known as an "increased lordosis" or a hyperlordosis.
