Uterine polyps can cause menstrual cramps. Uterine polyps, which include endometrial polyps and cervical polyps, may cause menstrual cramps in more severe cases. Uterine polyps have the potential to block the natural discharge of menstrual blood, causing it to not flow smoothly from the uterine cavity. The blocked menstrual blood builds up in the uterine cavity, causing abdominal pain that causes symptoms similar to dysmenorrhea. The pain is also relieved after the menstrual period clears. Once a uterine polyp is diagnosed, it is important to seek prompt medical attention and aggressive treatment. Endometrial polyps may also cause an abnormal increase in leukorrhea and irregular bleeding from the uterus, especially when having sex. Patients with uterine polyps should pay attention to keep the pubic area hygienic and dry, wear some loose cotton fabric underwear, and change the underwear diligently.
