Celiac disease does not cause pain during intercourse, mainly because celiac disease is a normal physiological phenomenon that does not cause corresponding symptoms, and you will only be informed of celiac disease during a gynecological examination. This is a normal physiological phenomenon and does not require appropriate intervention or treatment. If painful intercourse occurs, it is most often caused by local inflammation of the vagina, and friction after intercourse will aggravate the local inflammation, so it will cause pain. In addition, if intercourse causes pain in the lower abdomen, it may be due to endometriosis, which causes elasticity of the pelvic tissue to falsely descend, and therefore causes pain. Pelvic inflammatory disease can also lead to pain during intercourse, so it is important to actively check and give appropriate treatment according to the cause.
