Chronic active inflammatory erosion of the mucosa is a limited superficial defect of the epithelium that occurs in the location of the mucosa of the human body, where inflammatory factors persist and are in the active, fluctuating phase of the disease. Mucosa is a membranous structure in living organisms composed of epithelial and connective tissues, generally found in the body’s digestive system, respiratory system, urinary system, and the lining of the reproductive organs. Chronic inflammation indicates the persistence of inflammatory factors that damage the tissue. There are many different types of inflammatory factors, including bacteria, viruses, mycoplasma, fungi, and parasites. Chronic inflammation of the mucous membranes is a benign condition in itself and is not a serious disease, but it can have serious consequences. For example, when there is chronic inflammation of the cervical mucosa or the mucosa of the fallopian tube, it can easily lead to localized destruction of the mucosa, resulting in adhesions. Cervical adhesions can easily lead to amenorrhea and infertility, and tubal adhesions can lead to ectopic pregnancy or secondary infertility. Active means that the disease is in the state of onset as well as progression, when it is easy to feel the discomfort of the body. For example, in the active stage of gastritis, one is prone to stomach pain, bloating, nausea and other indigestion symptoms. Celiac disease is a superficial necrotic defect at the mucosa. It is recommended that patients seek timely medical treatment, improve relevant examinations, and actively deal with it under the guidance of specialists, so as not to miss the best time for treatment.
