What are the causes of tubal inflammation?

Patient's question:

What are the causes of tubal inflammation? I've been married for many years without getting pregnant. When I went to the hospital for a check-up, the doctor said I have tubal inflammation. I took a lot of medicine, but it didn't work at all. Sigh

Doctor's answer:

Hello, this patient. The cause of tubal inflammation is the upward spread of infection from the lower genital tract. It can present as chronic inflammatory changes due to improper or incomplete treatment.
If chronic tubal inflammation leads to incomplete obstruction of the fallopian tube lumen, it can increase the risk of ectopic pregnancy, resulting in habitual abortion. Additionally, when the fimbriae of the fallopian tube become adhered due to inflammation, tubal hydrops may occur. However, chronic tubal inflammation may not have obvious subjective symptoms, as its symptoms are very subtle. Clinically, many patients are only diagnosed after visiting the hospital for years of infertility or repeated miscarriages.
However, some patients may experience varying degrees of lower abdominal pain, lower back and sacral soreness, a sense of heaviness, frequent urination, menstrual irregularities, dysmenorrhea, increased leukorrhea, and depression—mild symptoms of chronic tubal inflammation. These symptoms are often easily confused with other diseases, making timely detection and treatment difficult.
