After the hysteroscopy surgery, there was bleeding about ten days later, but the amount was not large. How is it possible?

Patient's question:

What is the reason for bleeding after a hysteroscopy surgery for a few days, but the amount is not large? How many more days will the bleeding last? What is the cause? If the menstrual blood is too little.

Doctor's answer:

After hysteroscopy surgery, vaginal irrigation should be avoided as much as possible to prevent retrograde infection. It depends on the specific surgical condition, but a small amount of bleeding usually stops within 3 to 7 days. Pay attention to vaginal hygiene.
