The cervical epithelium has squamous and columnar epithelium. Normally, the squamous part of the cervical orifice is smooth, while the columnar epithelium has a rougher surface. When there is chronic inflammation or continuous stimulation by infection with papillomavirus, cervical squamous epithelium may produce inflammatory lesions, atypical hyperplastic lesions or even cancer. Cervical squamous epithelial hyperplasia suggests chronic cervicitis, which requires anti-inflammatory and antiviral treatment. If the hyperplasia is severe, it is better to have further examination to exclude the possibility of malignancy. During the treatment period, it is best not to have sex, eat more vegetables and fruits, and it is recommended to eat more food with high protein content, such as fish and shrimp, lean meat, etc., to enhance physical fitness and resistance, and the degree of recovery of the cervical epithelium needs to be reviewed regularly.
