Disease description:

After defecating at noon, I noticed blood coming from my vagina. What could be the reason? I feel embarrassed to go to the hospital for an examination, so I'd like to ask: what causes vaginal bleeding after a bowel movement?

It could be caused by gynecological diseases or ovulation-related bleeding. In early pregnancy, if a woman experiences bleeding after defecation, this may indicate threatened miscarriage, possibly due to abnormal embryonic development, and an ultrasound is needed for definitive diagnosis. Some women experience vaginal bleeding during ovulation due to ovulatory bleeding. It is recommended to undergo thorough examination and, based on the underlying cause, consider further treatment options such as surgery or other therapies.
