Post-Menopausal Changes: Will Fibroids Shrink After Menopause?

Red degeneration of fibroids, also known as degenerative fibroid, is a type of fibroid degeneration that usually occurs during pregnancy. It's caused by a sudden lack of blood supply, leading to the fibroids' rapid growth. 

Uterine fibroids can be diagnosed through different methods like a pelvic exam, ultrasound, or through a more detailed form of ultrasound called sonohysterography. 

While the exact cause isn't known, research suggests that estrogen and progesterone, the female hormones that regulate the menstrual cycle, may promote the growth of fibroids. 

All fibroids should be monitored, but generally, those larger than 5 centimeters may require attention due to potential complications like heavy menstrual bleeding or fertility issues.

Fibroids typically shrink after menopause due to the decrease in hormone levels. While there's no exact measurement, many women find relief from fibroid symptoms after menopause.

Submucosal fibroids are located in the uterus lining and can distort it, leading to heavier and prolonged periods. This is why they often cause abnormal bleeding. 

While both are growths that can occur in the female reproductive system, cysts usually form on the ovaries (known as ovarian cysts or fibroids), while fibroids develop in or around the uterus. 

Fibroids can potentially affect pregnancy depending on their size and location. For example, a large intramural fibroid located within the uterine wall may impact fertility or cause complications during pregnancy. It's always best to discuss fibroids pregnancy with your healthcare provider.
