Introduction

Under normal circumstances, the main causes of fluid accumulation in the uterus include physiological retention of menstrual blood, accumulation of follicular fluid during ovulation, endometritis, intrauterine adhesions, and cervical canal adhesions. If symptoms such as abdominal pain or abnormal vaginal discharge occur, it is recommended to seek timely medical consultation and treatment at a正规 hospital. In daily life, it is important to maintain good hygiene habits and avoid unclean sexual practices.

Generally, the main causes of fluid accumulation in the uterus include physiological menstrual blood residue, follicular fluid accumulation during ovulation, endometritis, intrauterine adhesions, and cervical canal adhesions. If symptoms such as abdominal pain or abnormal vaginal discharge occur, it is recommended to seek timely medical treatment at a formal hospital. Detailed explanations are as follows:

1. Physiological Menstrual Blood Residue

After menstruation ends, a small amount of menstrual blood may remain in the uterine cavity, forming temporary fluid accumulation. This condition does not require special treatment. Avoid strenuous exercise during menstruation and maintain external genital hygiene; the accumulated fluid usually discharges with the next menstrual period or is gradually absorbed.

2. Follicular Fluid Accumulation During Ovulation

During ovulation, after the ovary releases an egg, follicular fluid may flow into the uterine cavity, forming a small amount of fluid accumulation. This is a normal physiological phenomenon; maintaining regular作息 (作息 translates to作息 habits or作息 routine) helps, and the fluid usually disappears on its own.

3. Endometritis

Infections caused by pathogens such as bacteria can lead to endometritis. Inflammatory stimulation results in exudative fluid in the uterine cavity, forming fluid accumulation. Under a doctor's guidance, medications such as Cefaclor capsules, Levofloxacin tablets, and Metronidazole tablets can be used to control inflammation and promote absorption of the accumulated fluid.

4. Intrauterine Adhesions

Uterine cavity surgeries or infections may cause intrauterine adhesions, which obstruct the discharge of secretions or menstrual blood within the uterus, leading to fluid accumulation. Mild adhesions can be treated under a doctor's guidance with estrogen medications, such as Estradiol Valerate tablets, Conjugated Estrogens tablets, and Nylestriol tablets, to promote endometrial repair. Severe adhesions require surgical separation.

5. Cervical Canal Adhesions

Adhesions in the cervical canal due to injury or infection can block the discharge of fluid from the uterine cavity, leading to fluid accumulation. A cervical canal dilation procedure can be performed under medical supervision. Postoperative treatment may include Cefuroxime Axetil tablets to prevent infection, and attention to personal hygiene is necessary to avoid recurrence of adhesions.

In daily life, maintaining good hygiene habits, avoiding unclean sexual activity, minimizing unnecessary intrauterine procedures to reduce infection risk, keeping warm during menstruation to avoid cold exposure, and undergoing regular gynecological examinations to promptly detect and manage abnormalities are recommended.

What does it mean to see an anechoic area within the uterine cavity?

Intrauterine anechoic area usually refers to a region with no echo detected within the uterine cavity during an ultrasound examination. It may be associated with early pregnancy, intrauterine fluid accumulation, endometrial polyps, endometriosis, ectopic pregnancy, and other factors. If discomfort symptoms occur in daily life, it is recommended to visit a hospital for proper diagnosis and follow medical advice for treatment after identifying the specific cause.

What causes uterine contractions?

In general, uterine contractions may be caused by normal physiological responses during menstruation, postpartum uterine involution, endometritis, adenomyosis, intrauterine fluid accumulation, and other factors. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Daily, it is important to maintain a regular作息 (作息 should be translated as "routine" or "daily habits"), avoid staying up late and mental stress, and pay attention to hygiene during menstruation and sexual activity.

Why is the uterine fundus too high at 12 weeks of pregnancy?

Under normal circumstances, an excessively high uterine fundus at 12 weeks of pregnancy may be caused by miscalculation of gestational age, multiple pregnancy, intrauterine fluid accumulation, adenomyosis, uterine fibroids, or other factors. Symptomatic management may involve general treatment, medication, and other approaches. Pregnant women are advised to attend regular prenatal checkups at the hospital to monitor their health status and fetal development promptly.

What is fluid accumulation in the uterus?

Uterine fluid accumulation may be caused by factors such as fluid accumulation during ovulation, early pregnancy, uterine bleeding, endometrial polyps, or endometriosis. During a woman's ovulatory period, changes in estrogen levels may lead to increased secretion from the endometrial glands, resulting in a small amount of fluid accumulation. This fluid typically gets absorbed on its own after ovulation and does not affect a woman's health.
