The exact cause of uterine fibroids is unknown, but several factors may play a role. These include:

• Hormones: Two hormones called estrogen and progesterone cause the tissue that lines the inside of the uterus to thicken during each menstrual cycle to prepare for pregnancy. Fibroids tend to grow when hormone levels are higher, such as during pregnancy, and shrink when hormone levels are low, such as during the transition to menopause.

• Genetics: Many fibroids contain changes in genes that differ from those in typical uterine muscle cells.

• Race: Black people are more likely to have fibroids than people of other racial groups. They also tend to show up earlier and grow quicker in Black people.

• Reproductive age: Fibroids are most common in people of reproductive age, generally between 30-40 years old, but they can show up at any age.

• Obesity: Being overweight increases the level of estrogen in the body, which may increase the risk of developing fibroids.

• Family history: Fibroids may run in families.

Its important to note that many people who have uterine fibroids dont have any symptoms. In those who do, symptoms can be influenced by the location, size, and number of fibroids. The most common symptoms of uterine fibroids include heavy menstrual bleeding or painful periods, longer or more frequent periods, pelvic pressure or pain, frequent urination or trouble urinating, growing stomach area, and constipation. If you experience any discomfort or pain, its important to talk to your healthcare provider.
