Adnexitis may cause delayed menstruation. The principle of adnexitis causing delayed menstruation is that adnexitis affects the hormone level in the body and the change of hormone level may lead to delayed menstruation. The common types of adnexitis are: inflammation of the fallopian tubes and ovaries. If it is an inflammation of the fallopian tubes, it usually does not lead to delayed menstruation. Therefore, the situation of delayed menstruation will occur. Celiac disease not only causes delayed menstruation, but also affects normal ovulation and can cause infertility in severe cases. Once the diagnosis of celiac disease is confirmed, timely treatment is needed to avoid long-term stimulation leading to blockage of the fallopian tubes and ovarian cysts, which can have a serious impact on the health of the female reproductive system and is a common factor in infertility.
