Patient's question:
Lately, I've been feeling lower back pain and a heavy sensation in my lower abdomen. I'm not at ease about going to the hospital for a check-up, and they said it's due to fluid accumulation in the fallopian tubes. Could you please tell me: What causes fallopian tube blockage?Doctor's answer:
Tubal blockage is primarily caused by inflammation spreading from the endometrium upwards, first leading to inflammatory changes in the fallopian tube mucosa. This results in the regressive or patchy shedding of the fallopian tube epithelium, causing the mucosa to adhere together, and subsequently leading to the self-locking of the fallopian tube lumen or fimbriae. There are several causes of tubal blockage, and based on the severity of the blockage, there are three types: the first is fallopian tube patency but not smooth, the second is fallopian tube communication difficulties and blockage, and the third is complete fallopian tube blockage. These conditions are often triggered by downward infections from pathogens such as vaginal, cervical, endometritis, ovarian diseases, appendicitis, and tuberculosis. Additionally, tubal inflammation leading to blockage can be caused by secondary neuron tubal inflammation due to uterine cavity operations such as induced abortion, insertion of an intrauterine device (IUD), or removal of an IUD.
