Women with back pain and hair loss are usually a manifestation of kidney deficiency from the perspective of Chinese medicine, due to kidney yang deficiency or kidney yin deficiency resulting in insufficient moisturizing of the hair, resulting in premature hair loss, a manifestation of premature aging. If you have lumbar pain, you must rule out lumbar spine disease or kidney disease, for example, if you have lumbar spine disease, commonly lumbar muscle strain, third lumbar transverse synovial syndrome or lumbar disc herniation and other diseases, you can confirm the diagnosis by examining the lumbar spine CT or MRI. If there is percussion pain in the lumbar region bilaterally, it may be a disease of the urinary system, such as urinary stones or urinary tract infections or even tumors of the kidney, which may also cause pain in the lumbar region. Only after ruling out the above causes is hair loss considered to be caused by kidney deficiency in Chinese medicine.
