What are the causes of uterine fibroids? Why do uterine fibroids occur?

Patient's question:

Hello doctor, I recently went to the hospital for a gynecological examination. The doctor said I have uterine fibroids, but I haven't felt any discomfort in my body recently. Why would I have uterine fibroids?

Doctor's answer:

Uterine fibroids are a benign, multiple disease that is not contagious. They are most common in women aged 30-55, with very few cases occurring before the age of 20 or after 60. The incidence rate can be as high as 70%. Their occurrence is related to estrogen levels. Young patients with high estrogen levels have a higher probability of developing the disease. After menopause, when hormone levels decline, the fibroids can shrink or disappear on their own. Additionally, uterine fibroids are associated with the following factors: (1) Reproductive factors: Women who have never given birth are more likely to develop uterine fibroids compared to those who have. (2) Oral contraceptives: Contraceptives containing estrogen can stimulate the growth of uterine fibroids. (3) Obesity: Fat tissue can also produce estrogen, and uterine fibroids rely on estrogen for growth. (4) Family history: Sisters, daughters, and mothers of women with uterine fibroids may also be at risk of developing the condition. (5) Psychological factors: Excessive work stress, high pressure, or family discord can disrupt ovarian function, leading to the development of uterine fibroids.
