From the Guidelines
Chadwick's sign is a bluish hue, also known as cervical cyanosis, that appears on the cervix during pregnancy, as noted in the speculum examination 1. This sign is typically observed during early pregnancy and is considered one of the presumptive signs of pregnancy. The color change is due to increased vascularity and blood flow to the pelvic region as a result of hormonal changes, particularly the rise in estrogen levels.
- The increased blood supply causes congestion in the tissues, leading to the characteristic bluish appearance.
- Healthcare providers may look for Chadwick's sign during a pelvic examination as part of pregnancy assessment, though it is not definitive proof of pregnancy on its own.
- While Chadwick's sign is generally reliable, it can occasionally be observed in non-pregnant women with certain conditions that cause pelvic congestion, as described in the context of speculum examination and cervical findings 1.
- Therefore, it is typically used in conjunction with other pregnancy indicators rather than as a standalone diagnostic tool, considering the importance of accurate diagnosis and patient care 1.
