Cervical natriuresis is a chronic form of cervicitis. The puncture of a cervical natriuretic sac usually results in the discharge of colorless, clear mucus, and there is usually no blood flow, but there may be a small amount of bleeding from puncturing a blood vessel in the wall of the sac. Cervical cysts are mainly formed by the proliferation of superficial epithelium near the cervix, covering the opening of the cervical gland ducts, or blocking the opening of the gland ducts. It is usually caused by obstruction of mucus drainage or an inflammatory infection. Small yellowish-white vesicles usually form on the surface of the cervix, and the vesicle fluid is clear and brightly colored. When punctured, colorless mucus is usually discharged, and blood does not usually flow, but there may be a small amount of bleeding from puncturing the blood vessels in the wall of the vesicle. If cervical natriuresis occurs, there is no need to be overly nervous, and it is recommended to go to the hospital in time for cervical cancer related examinations, such as TCT, HPV, and so on. If there is no abnormality in the examination, regular rechecking will be fine. If the cervical natriuretic sac protrudes beyond the cervical opening or causes other uncomfortable symptoms, surgical removal of the cervical natriuretic sac may be required.
