Celiac disease is not a disease, but it is important to prevent it. Celiac disease is a very common medical term in clinical practice, but the term celiac disease has been eliminated from current textbooks because it can cause many misunderstandings. Celiac disease usually refers to a piece of the cervix that looks redder and thinner, like it has shed a piece, thinking it is celiac disease, but in fact modern medicine has found that it is not really celiac disease, but a piece of columnar epithelium, which is originally thinner, so celiac disease is not a disease. Why is it important to prevent disease? Because the appearance of a diseased cervix does not look very different from that of a non-diseased cervix, so if cervical erosion is detected, it is important to undergo cancer screening of the cervix. If the screening result is not a problem, cervical erosion is a physiological manifestation and does not require treatment because it is not a disease.
