The female reproductive system has a self-defense mechanism. Once the mechanism is destroyed, it's susceptible to bacterial infection and disease. Among them, pelvic inflammatory disease is a type of gynecological disease. So, what are causes of pelvic inflammatory disease? What is the danger of pelvic inflammatory disease? How to treat pelvic inflammatory disease? In addition, how to prevent pelvic inflammatory disease? The inflammation that comes about in the connective tissue near the uterus, the genital tube within the pelvis, along with the peritoneum is pelvic inflammatory disease. There are chronic and acute points, and chronic pelvic inflammatory disease is usually a result of the incomplete cure of the acute stage, that's more stubborn and includes a longer onset.In life, you will find just one or two women with this particular disease, because the reproductive : includes a self-protective function that protects itself from bacterial infections. However, once the body function declines, or if the defense function is damaged by other factors, it won't resist the invasion of bacteria, which can lead towards the occurrence with this disease. Pelvic inflammatory disease could be split into three categories: 1.Fallopian hydronephrosis and fallopian tube ovarian cyst If the fallopian tube is inflamed, its umbrella ends will stick together to make a closed state. The wall with the tube will flow out in the slurry liquid and remain inside to form stagnant water; sometimes the accumulated pus will be absorbed, causing stagnant water; A cyst within the attachment area will result. 2.Salpingitis This is the most common type. Inflammation causes damage for the mucosa and interstitial in the fallopian tube. The fallopian tube becomes thicker and gradually becomes fibrillar, which then causes the ovaries, fallopian tubes and surrounding tissues to participate together to form a hard and fixed mass. 3.Chronic pelvic connective tissue inflammation The extent of inflammation extends to the connective tissue and patellar ligaments adjacent on the uterus; the texture of some tissues becomes hard, the thickness increases, and the fan shape expands outward before the pelvic wall, along with the uterus could be pulled toward the inflamed or fixed. If you have pelvic inflammatory disease, I recommend fuyan pills to treat it.
