Introduction

Under normal circumstances, the main causes of uterine cysts include unruptured physiological follicles, blocked cervical gland ducts, chronic cervicitis, endometriosis affecting the uterus, and pelvic adhesions compressing the uterine gland ducts. If symptoms such as lower abdominal heaviness or menstrual irregularities occur, it is recommended to seek timely medical evaluation and treatment at a reputable hospital. A detailed analysis is as follows:

Generally, the main causes of uterine cysts include unruptured physiological follicles, blocked cervical gland ducts, chronic cervicitis, endometriosis affecting the uterus, and pelvic adhesions compressing the uterine gland ducts. If symptoms such as lower abdominal heaviness or menstrual irregularities occur, it is recommended to seek timely medical consultation and treatment at a reputable hospital. Detailed explanations are as follows:

1. Unruptured Physiological Follicles

Women of childbearing age undergo periodic ovulation, and if a follicle fails to rupture and continues to grow, it may form a physiological cyst, sometimes mistaken as a uterine cyst. This condition typically requires no special treatment. Maintaining regular作息 (作息 means作息 in Chinese, which can be translated as作息 habits or作息 patterns)作息 habits, avoiding excessive fatigue, and the cyst usually disappears spontaneously within 1-3 menstrual cycles.

2. Blocked Cervical Gland Ducts

The gland ducts in the cervix secrete mucus, and if the duct openings become blocked, the mucus cannot be discharged and may accumulate forming cervical cysts, a common type of uterine-related cyst. It is important to maintain external genital hygiene, avoid unclean sexual practices, and reduce the risk of cervical infection. Small cysts can simply be monitored with regular follow-up examinations.

3. Chronic Cervicitis

Long-term chronic cervicitis can irritate the cervical gland ducts, leading to narrowing or blockage of the ducts and subsequently forming cervical cysts. Under a physician's guidance, medications such as azithromycin dispersible tablets, cefixime capsules, and metronidazole suppositories may be used to control inflammation and relieve symptoms.

4. Endometriosis Affecting the Uterus

If endometriotic lesions involve the uterus, they may affect local tissue metabolism and promote cyst formation. Under medical guidance, medications such as drospirenone ethinylestradiol tablets, dydrogesterone tablets, and gestrinone capsules can be used to inhibit the growth of ectopic endometrium and alleviate symptoms.

5. Pelvic Adhesions Compressing Uterine Gland Ducts

Pelvic adhesions can compress gland ducts around the uterus, blocking the discharge of secretions and resulting in cyst formation. Mild adhesions can be relieved through heat application, physical therapy, and other methods. Severe cases require surgical lysis after medical evaluation, and postoperative use of cefuroxime axetil tablets may help prevent infection.

In daily life, it is important to maintain good hygiene habits, frequently change underwear, avoid multiple intrauterine procedures to reduce injury to the uterus and cervix, maintain regular作息 habits, enhance physical resistance, and undergo regular gynecological examinations to promptly detect and manage abnormalities such as cysts.

Can an ectopic pregnancy be detected using a pregnancy test strip?

Ectopic pregnancy usually refers to a pregnancy occurring outside the uterus. In general, whether an ectopic pregnancy can be detected by a home pregnancy test depends on the specific circumstances. If the test result is positive but accompanied by symptoms such as abdominal pain or irregular vaginal bleeding, medical evaluation should be sought promptly to rule out the possibility of an ectopic pregnancy. If the result is negative but menstruation has not occurred, it is recommended to repeat the test after 3–5 days.

What are the functions of the uterus?

The uterus has several important functions, including孕育 embryos and fetuses, forming menstrual cycles, secreting hormones and regulating the endocrine system, protecting pelvic organs, and participating in reproductive immune regulation. In daily life, it is essential to protect the uterus by maintaining regular作息, avoiding excessive fatigue, and undergoing routine gynecological examinations. If abnormalities such as irregular menstruation or abdominal pain occur, prompt medical evaluation should be sought to rule out uterine-related conditions and maintain reproductive health.

What are the ways to restore normal function in cases of uterine prolapse?

Uterine prolapse, also known as uterine descent, requires treatment methods selected according to the severity of the condition. Generally, recovery can be achieved through consistent pelvic floor muscle exercises, adjustment of daily posture, use of uterine pessaries, physical therapy, and surgical intervention. The recovery plan should be developed based on the degree of prolapse; mild cases are primarily managed with conservative treatments, while severe cases require timely evaluation for the necessity of surgery.
