Menstruation is menstruation, and women who are menstruating can have an abdominal ultrasound, but a vaginal ultrasound is prohibited. If a menstruating woman suspects abdominal diseases such as appendicitis, pancreatitis, pelvic fluid, uterine fibroids, etc., she can have an abdominal ultrasound even if she is menstruating, and abdominal ultrasound can help in the diagnosis and treatment of these diseases. However, it is important to note that vaginal ultrasound is prohibited for women who are menstruating because it is not beneficial to women and the results cannot be seen. Therefore, whether or not ultrasound can be performed on menstruation needs to be determined based on the type of ultrasound and the patient’s condition. In addition, those who have doubts are advised to seek medical advice and consult with a medical professional in time and under his/her guidance to avoid delaying their condition.
