Large lumbar curvature will not become shorter in general, but it may become shorter under certain special circumstances. 1. General situation: lumbar curvature is also known as kyphosis, most of which is caused by physiological reasons, such as long-term stooping, hunchback, work, heavy manual labor, etc. After timely correction of the wrong posture, it will not lead to shortness of height in general. 2. Special circumstances: certain pathological factors such as lumbar spondylolisthesis, congenital kyphosis, trauma, etc., can result in decreased spinal stability, decreased lumbar muscle strength, narrowing of the intervertebral space, anterior pelvic tilt and other pathologic changes, which, if not treated in a timely manner, may lead to shortening of height. If lumbar curvature is suspected to be enlarged, it is recommended to visit the clinic for examination and standardized treatment as early as possible in order to reduce the adverse effects of the disease.
