Common causes of bleeding after a hysterectomy include healing tissue and dissolving sutures, according to Mayo Clinic. Patients normally experience light vaginal bleeding for several days and up to six weeks after the surgery. Patients with heavy bleeding or bleeding lasting more than six weeks should talk to their doctors.
A patient typically wears sanitary napkins while experiencing bloody vaginal discharge or spotting after a hysterectomy, the surgery a doctor performs to remove the uterus, notes Mayo Clinic. Doctors perform the surgery to treat conditions including endometriosis, uterine fibroids, uterine prolapse and cancer, which accounts for about 10 percent of hysterectomies, according to the Illinois Department of Public Health.
