Introduction

Under normal circumstances, the main causes of adenomyosis include fewer pregnancies, aging, abnormal hormone levels, endometrial damage, and chronic endometritis. If discomfort symptoms occur, it is recommended to seek timely medical treatment at a正规 hospital. In daily life, it is important to maintain good hygiene habits to prevent gynecological inflammation.

Generally, the main causes of adenomyosis include fewer childbirths, aging, abnormal hormone levels, endometrial damage, and chronic endometritis. If discomfort symptoms occur, timely visit to a regular hospital for diagnosis and treatment is recommended. Detailed analysis is as follows:

1. Fewer Childbirths

Women who have not given birth or have had few pregnancies lack the physiological shedding and repairing of the endometrium during pregnancy, which may increase the risk of endometrial invasion into the myometrium, causing adenomyosis. Women planning pregnancy can give birth at an appropriate time to reduce the chance of abnormal endometrial hyperplasia through pregnancy.

2. Aging

With aging, women's ovarian function gradually declines, accompanied by hormonal fluctuations. The endometrium is prone to abnormal hyperplasia and invasion into the uterine muscle layer, leading to adenomyosis. Middle-aged and elderly women should undergo regular gynecological examinations for early detection and intervention.

3. Abnormal Hormone Levels

Elevated estrogen levels or insufficient progesterone can stimulate excessive endometrial hyperplasia, increasing the possibility of invasion into the myometrium, leading to adenomyosis. When symptoms are obvious, hormone-regulating medications such as dydrogesterone tablets, medroxyprogesterone acetate tablets, or the levonorgestrel-releasing intrauterine system may be used under medical guidance to alleviate symptoms. Severe cases may require adenomyosis lesion resection.

4. Endometrial Damage

Procedures such as induced abortion and intrauterine surgery can damage the basal layer of the endometrium, making it easier for endometrial tissue to invade the uterine myometrium, triggering adenomyosis. Effective contraception should be practiced to reduce unnecessary intrauterine procedures and lower the risk of endometrial injury.

5. Chronic Endometritis

Long-term chronic endometritis disrupts the normal structure of the endometrium, promoting the growth of endometrial tissue into the myometrium, inducing adenomyosis. Under medical guidance, anti-inflammatory medications such as cefixime capsules, metronidazole tablets, and clindamycin phosphate tablets may be used to control inflammation and prevent disease progression.

In daily life, maintaining good hygiene habits to prevent gynecological inflammation, avoiding excessive fatigue, maintaining regular作息 (作息 means rest and work schedules), reducing intake of high-estrogen foods such as royal jelly and snow frog oil, and undergoing regular gynecological examinations to monitor uterine health are recommended.

What does it mean to have two menstrual periods in one month?

Having two menstrual periods usually refers to experiencing menstruation twice. In general, the main causes of having two menstrual cycles include emotional fluctuations, irregular lifestyle, luteal phase deficiency, endometrial polyps, adenomyosis, and others. If any discomfort occurs, it is recommended to promptly seek medical attention at a正规 hospital for proper diagnosis and treatment. In daily life, maintain a regular sleep schedule and avoid staying up late; also ensure a balanced diet.

In general, the main causes of having menstrual periods every half month include hormonal fluctuations during puberty, excessive stress, luteal phase deficiency, endometrial polyps, and adenomyosis. If this condition occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital.

How are uterine fibroids caused?

Under normal circumstances, the main causes of uterine fibroids include hormonal changes, aging, endometritis, polycystic ovary syndrome, and adenomyosis. If discomfort symptoms occur, it is recommended to seek timely medical treatment at a正规 hospital. In daily life, one should maintain external genital hygiene and avoid unclean sexual activity; maintain a regular diet and balanced nutrition.

How large is the size of uterine adenomyosis considered severe?

To determine the severity of adenomyosis, the size of the lesion should not be the sole criterion. A comprehensive assessment is required, taking into account the extent of the lesion, symptom presentation, growth rate, and impact on fertility. Generally, the condition is considered relatively mild when the lesion is localized, the uterine volume is not significantly increased, and symptoms are mild. However, the condition may be more severe if the lesion is extensive, the uterine volume is markedly increased, or symptoms significantly affect quality of life, even if individual lesions are not large.
