Simple cervical erosion is not considered a disease, so there are no symptoms associated with cervical erosion itself. However, if the cervical erosion is due to inflammation, resulting in a large affected area, abnormal secretions, or contact bleeding, then treatment must be aimed at addressing the infection. All women, regardless of whether they have cervical erosion, should undergo routine screening for precancerous cervical lesions. The decision on whether to treat and what treatment to opt for should be based on the presence or absence of precancerous cervical lesions or cervical vaginal inflammation.

How long does cervical erosion bleed after the scab falls off?

Cervical erosion, if treated with methods like laser or electrocoagulation, may experience bleeding during the scab shedding process. This bleeding usually ceases within about a week. It is common for the blood volume to increase slightly when the scabs fall off, then the bleeding gradually decreases, and stopping within a week is considered normal. If bleeding persists for more than a week after treatment for cervical erosion, it is necessary to visit a hospital for relevant examinations, and receive targeted treatments based on the condition of the cervical wound. If there is active bleeding, treatment should be based on the examination results. Therefore, if bleeding due to scab shedding from cervical erosion lasts excessively long, it is crucial to seek appropriate medical attention at a hospital. Generally, sexual intercourse should be avoided within a month after the operation for cervical erosion, and anti-inflammatory targeted treatments are necessary post-surgery.

Is cervicitis the same as cervical erosion?

Cervicitis is a common inflammation of the female lower genital tract. It is often caused by pathogenic infections of the cervix, leading to cervicitis lesions, most commonly presenting symptoms such as purulent vaginal discharge, vulvar itching, bleeding after intercourse, and visible cervical bleeding and edema during gynecological examinations. This condition requires antibiotic treatment. Cervical erosion, strictly speaking, is not a disease. Cervical erosion occurs when glandular epithelial cells from inside the cervical canal grow outward onto the external part of the cervix. Since glandular epithelial cells are thin, they appear bright red, resembling erosion, thus colloquially termed cervical erosion. These externalized glandular epithelial cells are susceptible to viral or bacterial invasion, causing cervical lesions, thus medicinal treatment is also often recommended.

How is cervical erosion treated?

Cervical erosion is not considered a disease, so there is no need for any treatment for cervical erosion, including the use of anti-inflammatory drugs or various physical therapies such as laser, microwave, LEEP, etc. Simple cervical erosion is just a physiological condition, and routine cervical precancerous lesion screening is necessary. If there are no precancerous cervical lesions, and if the usual secretions are normal without abnormal odor or itching, then no treatment is needed if there is no infection.

Cervical erosion is classified into several grades.

Cervical erosion is generally divided into three grades: Grade 1 cervical erosion refers to erosion covering less than one-third of the total cervical area, which is also called mild erosion. Grade 2 erosion, also known as moderate-to-severe erosion, refers to the erosion covering about two-thirds of the total area, which is considered moderate, being the middle grade of erosion. Grade 3 cervical erosion is the last and most severe grade, also known as severe erosion. In this case, the erosive area exceeds two-thirds of the entire cervical area, and may even involve the entire cervix. This condition is generally more serious and typically requires examination including a TCT (ThinPrep Cytologic Test) and HPV (Human Papillomavirus) co-screening to investigate the possibility of cervical lesions. Further assessments might include a colposcopy or localized treatment, as severe erosion could lead to symptoms like contact bleeding and increased discharge that need to be addressed.

Can you swim with cervical erosion?

Cervical erosion is permissible for swimming because cervical erosion itself is not considered a disease; it is merely a physiological condition, a normal physiological phenomenon in young women. Cervical erosion is due to high estrogen levels in young people, leading to the proliferation and externalization of columnar epithelium, which is a normal state. It does not affect daily life, including swimming. As long as the water quality in the swimming pool meets health standards and does not lead to infections, normal daily activities can be carried out. Therefore, there is no need to be overly concerned about cervical erosion detected during a physical examination.
