Lordosis

Overview

Some lordosis is normal. Too much is referred to as swayback. It may be inherited or caused by conditions such as arthritis, muscular dystrophy, and dwarfism.

Symptoms

Lordosis causes an unusually large, inward arch on the lower back, just above the buttocks. The condition may cause lower back pain.

Treatments

In children, lordosis often fixes itself. Some adults with lordosis may need physical therapy.
