Flat foot is a postural defect where the arches of the feet are flattened, causing the entire sole of the foot to touch the ground when standing. Kyphosis is a postural defect where there is an excessive outward curvature of the spine, resulting in a hunched or rounded upper back. Lordosis is a postural defect where there is an excessive inward curvature of the spine, resulting in a swayback or exaggerated lower back curve.

It can lead to a variety of health problems, including stunted growth, anemia, and weakened immune system, but it is not a postural defect.
