Pelvic tilt is a misalignment that occurs when the position of the pelvis is shifted relative to the normal pelvic position, and a severely tilted pelvis can have a relative impact on the body. It can cause energy loss, and in severe cases, it can cause a burden on the lower back, increasing the feeling of low back pain. At the same time, it will lead to changes in the center of gravity, causing the hips to be more flat and sagging, resulting in the body’s center of gravity to the rear. The spine will shift forward in order to balance the body’s center of gravity, forming a hunchback, narrowing of the chest, and it can lead to severe back and leg pain. In addition to this, a severe posterior pelvic tilt shift can also affect the normal functioning of the internal organ systems. When there is a flat change in the posterior tilt the body loses energy, resulting in lumbar spine changes that can put pressure on the reproductive system in the lower abdomen, affecting the health of the reproductive system. For women, this can lead to a series of symptoms such as menstrual disorders and dysmenorrhea, and in severe cases, it can affect fertility.
