Why does the pelvis tilt forward?
Generally, anterior pelvic tilt may be caused by prolonged wearing of high heels, pregnancy, flat feet, muscle strength imbalance in the waist and abdominal areas, lumbar spinal stenosis, and other reasons. Specific analyses are as follows:
1. Prolonged wearing of high heels
Some female patients who wear high heels for extended periods may experience a forward shift in their body's center of gravity to maintain balance, leading to anterior pelvic tilt. It is recommended that patients wear high heels less frequently and opt for comfortable flat shoes instead.
2. Pregnancy
During pregnancy, as gestational weeks increase, the body's load gradually increases. With rapid fetal growth and development, abdominal volume and weight expand progressively. Once the stress on the lumbar spine reaches its limit, significant anterior tilting may occur. Anterior pelvic tilt during pregnancy is a normal physiological response. After delivery, the body will gradually recover, and symptoms of pelvic tilt will naturally subside, requiring no special treatment.
3. Flat feet
Patients with chronic flat feet may experience altered distribution of body weight. The body’s center of gravity shifts abnormally from its normal skeletal alignment and transfers excessive load to the lumbar spine. To compensate and maintain balance, the pelvis adjusts its position, resulting in anterior pelvic tilt. Mild cases can usually be managed conservatively through physical therapies such as acupuncture, or by strengthening the intrinsic and extrinsic foot muscles. In severe cases involving deformity or pain, surgical intervention may be necessary.
4. Muscle strength imbalance in the waist and abdomen
An imbalance between the muscular strength of the lower back and abdomen can lead to tight back muscles and overactive abdominal muscles, causing anterior pelvic tilt. Treatment may include massage therapy. Additionally, patients are advised to regularly perform exercises such as Pilates and balance training to improve core stability.
5. Lumbar spinal stenosis
In patients with lumbar spinal stenosis, the narrowed spinal canal may compress the cauda equina nerves, causing symptoms such as low back and leg pain. To alleviate pain, patients may instinctively lean forward, which temporarily increases spinal canal volume. However, long-term forward leaning can lead to anterior pelvic tilt. Patients are advised to seek timely medical evaluation and treatment; surgical correction may be required in some cases.
It is recommended that patients seek prompt medical attention when experiencing discomfort and receive standardized treatment under professional guidance to facilitate recovery.
