What are the causes of tubal adhesion?

The fallopian tube, known as the "channel of life," is a crucial component of the female reproductive system, responsible for transporting the fertilized egg to the uterine cavity for normal implantation and pregnancy. Relevant data shows that fallopian tube obstruction accounts for about one-third of infertility cases among infertile patients. Fallopian tube-related infertility has become an important factor in female infertility.

1. Dysmenorrhea and Menstrual Irregularities: Early fallopian tube obstruction can lead to dysmenorrhea or worsening dysmenorrhea due to pelvic congestion and blood stagnation. This pain is mainly felt in the abdomen before menstruation, intensifying as menstruation approaches.

2. Infertility: Abnormalities or obstruction in the fallopian tube can lead to infertility, with secondary infertility being more common. This prevents the combination of sperm and eggs or the fertilized egg from entering the uterus, resulting in infertility.

3. Abdominal Pain: Fallopian tube obstruction can cause varying degrees of pain in the lower abdomen, often manifested as implicit discomfort, pain, swelling, and a feeling of falling in the back and sacrum. This pain tends to worsen with fatigue and should be taken seriously.

Causes of Fallopian Tube Obstruction: Fallopian tube obstruction is primarily caused by inflammation spreading upward through the endometrium, initially causing inflammatory changes in the fallopian tube mucosa, with degenerative or shedding changes in the fallopian tube epithelium, leading to adhesion and obstruction of the fallopian tube mucosa. Common causes include:

1. Gynecological Inflammation: Untreated or incompletely treated gynecological inflammation can persist. Long-term inflammation stimulation can lead to fallopian tube congestion, edema, thickening, hardening, adhesion, and narrowing of the lumen, eventually causing fallopian tube obstruction and infertility.

2. Induced Abortion: Mechanical stimulation, improper surgery, or incomplete abortion can lead to secondary inflammatory infections in women. With the invasion of various pathogens, the infection spreads from the uterus to the pelvic cavity and fallopian tubes, causing fallopian tube infection and obstruction.

3. Prolonged Vaginal Bleeding: Excessive, prolonged, or irregular vaginal bleeding due to gynecological tumors, dysfunctional uterine bleeding, or uterine pathology can occur. If left untreated, this can lead to secondary inflammatory infections, causing ulcers, adhesions, and obstruction in the inner wall of the fallopian tube.
