Bleeding stopped for several days after uterine evacuation, but then reappeared.

After a uterine evacuation procedure, bleeding may stop initially but reappear several days later. This could be due to physiological factors or pathological causes such as tissue remnants or cervical polyps. Appropriate management should be based on the individual patient's condition. The specific analysis is as follows:

I. Physiological Factors

Uterine evacuation is primarily a surgical procedure that removes residual tissues and other materials from the uterine cavity, commonly used for conditions such as abnormal uterine bleeding or incomplete abortion. If sexual intercourse occurs too soon after the procedure, it may increase sensitivity in the genital area and cause abnormal congestion of the mucous membranes, leading to the reappearance of bleeding several days after it had stopped. This is considered a normal phenomenon and typically resolves spontaneously.

II. Pathological Factors

1. Tissue Remnants

If improper surgical technique leaves some tissue inside the uterine cavity, the retained tissue may necrotize and produce purulent discharge, resulting in recurrent bleeding. It is recommended to visit a hospital for evaluation and possibly undergo a second evacuation procedure.

2. Cervical Polyps

If the patient has cervical polyps, mechanical stimulation of the abdomen may cause the surface of the polyp to rupture, leading to capillary bleeding and subsequent spotting. It is advisable to seek medical care at a hospital, where the cervical polyp can be surgically removed.

In addition, this symptom may also result from wound infection, uterine fibroids, or cervical cancer. It is recommended to avoid strenuous activities and refrain from taking baths (especially sitz baths) for a short period after the procedure.
