Uterine fibroids have more causes, mainly related to various factors such as dietary habits, age, genetic factors, hormone levels and so on. 1. Dietary habits, if you often do not pay attention to your diet and eat food containing more estrogen for a long time, it may lead to the body being affected, thus inducing uterine fibroids. 2. Age, some patients are older, which may lead to metabolic disorders in the body and fibroids. 3. Genetic factors, if someone in the family has fibroids, the possibility of fibroids in the offspring will increase. 4. Hormone levels. If there are hormonal changes in the body, a high production of estrogen may stimulate the uterus and cause fibroids to grow. If fibroids are already present, you need to actively seek medical examination and treatment.
