Introduction

Under normal circumstances, uterine fibroids may be caused by factors such as high hormone levels during the reproductive years, family genetic factors, endocrine disorders, chronic inflammation of the uterus, and polycystic ovary syndrome. It is recommended to seek timely medical attention, identify the underlying cause, and then improve the condition through lifestyle adjustments, medication, or other treatments under a doctor's guidance.

Under normal circumstances, uterine fibroids may develop due to high hormone levels during the reproductive years, family genetic factors, endocrine disorders, chronic uterine inflammation, polycystic ovary syndrome (PCOS), and other related factors. It is recommended to seek timely medical consultation, identify the underlying causes, and then improve the condition through lifestyle modifications, medication, and other approaches under a doctor's guidance. Detailed explanations are as follows:

1. High Hormone Levels During the Reproductive Years: In women of reproductive age, the ovaries secrete high levels of estrogen and progesterone. Continuous stimulation of these two hormones may lead to excessive proliferation of uterine smooth muscle cells, making the formation of uterine fibroids more likely. This condition is commonly seen in women aged 30 to 50. It is advisable to reduce daily intake of foods containing estrogen, such as royal jelly and snow frog oil.

2. Family Genetic Factors: Uterine fibroids demonstrate a certain hereditary tendency. If a woman's mother or close relatives have had uterine fibroids, the risk of developing the condition increases in offspring, which may be related to genetic inheritance. Gynecological screening should begin earlier, and annual gynecological ultrasound examinations are recommended for early detection and early intervention.

3. Endocrine Disorders: Long-term mental stress and irregular sleep patterns can cause endocrine imbalances, leading to relatively high estrogen levels that stimulate abnormal proliferation of uterine smooth muscle and result in fibroid formation, often accompanied by menstrual disorders. Follow medical advice to use medications such as Guizhi Fuling Capsules, Hongjin Xiaojie Tablets, and Gongliu Xiao Capsules to regulate hormonal balance.

4. Chronic Uterine Inflammation: Long-term infection of the uterus by bacteria, mycoplasma, and other pathogens can cause chronic inflammation. This inflammation may stimulate uterine smooth muscle proliferation, gradually leading to fibroid development, often accompanied by lower abdominal pain and increased vaginal discharge. Follow medical advice to use anti-infective medications such as Cefuroxime Axetil Tablets, Levofloxacin Hydrochloride Capsules, and Metronidazole Tablets.

5. Polycystic Ovary Syndrome (PCOS): Endocrine disorders can lead to elevated androgen levels and abnormal ovulation. Continuous estrogen stimulation of the uterus without sufficient progesterone antagonism makes uterine fibroids more likely to develop, often accompanied by hirsutism and oligomenorrhea. Follow medical advice to use hormonal-regulating medications such as Ethinyl Estradiol and Cyproterone Acetate Tablets, Drospirenone-Ethinyl Estradiol Tablets, and Spironolactone Tablets to improve ovulation.

In daily life, maintain a light diet and reduce the intake of spicy and greasy foods. Avoid long-term use of health products or medications containing estrogen. Pay attention to menstrual hygiene, avoid unclean sexual practices, and manage health effectively to reduce the risk of uterine fibroid growth and maintain uterine health.

What should I do if I become pregnant with uterine fibroids?

In general, women who become pregnant with uterine fibroids should manage their condition through enhanced prenatal monitoring, adjustment of daily activities, attention to nutritional diet, awareness of physical symptoms, and cooperation with medical interventions. It is important to maintain a positive mindset during pregnancy and avoid excessive anxiety, as anxious emotions may affect hormone levels and jeopardize pregnancy stability. At the same time, maintain close communication with the physician to stay informed about both maternal and fetal conditions.

Is uterine fibroid serious?

In general, the severity of uterine fibroids needs to be determined based on their size, symptoms, and growth pattern. Small fibroids without symptoms are usually not serious and do not require special treatment; however, fibroids that cause significant symptoms or grow rapidly are considered more severe and require timely intervention. In daily life, it is important to maintain a regular作息 (作息 should be translated as "routine" or "lifestyle rhythm"), avoid excessive fatigue, limit the intake of foods high in estrogen, and reduce the risk of fibroid growth.

What causes bleeding during ovulation?

In general, bleeding during the ovulation period may be caused by a temporary decline in estrogen levels, vigorous exercise, endometritis, cervical polyps, submucosal uterine fibroids, or other factors. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Additionally, it is important to maintain menstrual hygiene, change sanitary products frequently, and avoid unclean sexual practices.
