Why does the lower back hurt in the early stages of pregnancy?

Patient's question:

No

Doctor's answer:

Hormone secretion changes in the human body during pregnancy. After becoming pregnant, the body secretes a hormone to ensure that the baby can pass smoothly through the birth canal during delivery. This hormone relaxes the ligaments connecting the pelvis, and at the same time, it also relaxes the muscles, increasing the curvature of the spine, which can easily lead to lower back pain.
