Red degeneration involves bleeding into the fibroid tissue

Red degeneration involves bleeding into the fibroid tissue, leading to areas of hemorrhage within the fibroid. In pregnant women with uterine fibroids, red degeneration can occur due to the following:

Increased Blood Flow: During pregnancy, there is a significant increase in blood flow to the uterus to support the growing fetus. This increased blood flow can lead to vascular congestion within the fibroid tissue, making it more prone to hemorrhage.

Hormonal Changes: Pregnancy is associated with fluctuations in hormone levels, particularly estrogen and progesterone. These hormonal changes can affect the vascular supply to the fibroids and make them more susceptible to bleeding and degeneration.

Mechanical Factors: The growing uterus during pregnancy can exert pressure on the surrounding tissues, including fibroids, leading to compression of blood vessels and potential compromise of blood flow, which may contribute to hemorrhagic degeneration.

Rapid Growth: Fibroids may undergo rapid growth during pregnancy due to hormonal stimulation, increasing the likelihood of vascular compromise and hemorrhagic degeneration.

While hyaline degeneration is the most common type of degeneration overall, red degeneration is specifically associated with pregnancy-related changes in the uterus and fibroids.
