Dysfunctional uterine bleeding

  1. 1. DR FAISAL AL HADDAD CONSULTANT OF FAMILY MEDICINE & OCCUPATIONAL HEALTH Dysfunctional Uterine Bleedin
  2. 2. Background DUB is irregular uterine bleeding that occurs in the absence of recognizable pelvic pathology, general medical disease, or pregnancy. It reflects a disruption in the normal cyclic pattern of ovulatory hormonal stimulation to the endometrial lining. The bleeding is unpredictable in many ways. It may be excessively heavy or light and may be prolonged, frequent, or random. About 1-2% of women with improperly managed anovulatory bleeding eventually may develop endometrial cancer.
  3. 3. Signs and symptoms DUB should be suspected in patients with unpredictable or episodic heavy or light bleeding despite a normal pelvic examination. Typically, the usual moliminal symptoms that accompany ovulatory cycles will not precede bleeding episodes.
  4. 4. Signs and symptoms Because DUB is considered a diagnosis of exclusion, the presence or absence of signs and symptoms of other causes of anovulatory bleeding must be determined. Patients who report irregular menses since menarche may have polycystic ovarian syndrome (PCOS). PCOS is characterized by anovulation or oligo-ovulation and hyperandrogenism. These patients often present with unpredictable cycles and/or infertility, hirsutism with or without hyperinsulinemia, and obesity.
  5. 5. Signs and symptoms Thyroid enlargement or manifestations of hyperthyroidism or hypothyroidism Galactorrhea: May suggest hyperprolactinemia Visual field deficits: Raise suspicion of intracranial/pituitary lesion Ecchymosis, purpura: Signs of bleeding disorder
  6. 6. Diagnosis Laboratory studies  Human chorionic gonadotropin (HCG)  Complete blood count (CBC)  Papanicolaou test (Pap smear)  Endometrial sampling  Thyroid functions and prolactin  Liver functions  Coagulation studies/factors
  7. 7. Diagnosis Imaging studies  In obese patients with a suboptimal pelvic examination or in patients with suspected ovarian or uterine pathology, pelvic ultrasonographic evaluation may be helpful.  Ultrasonography can be used to identify uterine fibroids, as well as endometrial conditions, including hyperplasia, carcinoma, and polyps. Procedures  Rule out endometrial carcinoma in all patients at high risk for the condition  Traditionally, carcinoma was ruled out by endometrial sampling via D&C. However, endometrial sampling in the office via aspiration, curetting, or hysteroscopy has become popular and is also relatively accurate.
  8. 8. Management Pharmacologic treatment  Oral contraceptives: Suppress endometrial development, reestablish predictable bleeding patterns, decrease menstrual flow, and lower the risk of iron deficiency anemia  Estrogen: Prolonged uterine bleeding suggests the epithelial lining of the cavity has become denuded over time; estrogen administered alone will rapidly induce a return to normal endometrial growth  Progestins: Chronic management of DUB requires episodic or continuous exposure to a progestin  Desmopressin: A synthetic analogue of arginine vasopressin, desmopressin has been used as a last resort to treat abnormal uterine bleeding in patients with documented coagulation disorders
  9. 9. Management Hysterectomy may be necessary in patients who : have failed or declined hormonal therapy, have symptomatic anemia, and are experiencing a disruption in their quality of life from persistent, unscheduled bleeding. Endometrial ablation is an alternative for patients who wish to avoid hysterectomy or who are not candidates for major surgery.
