Read the passage and answer the question.
Physician notes:
A 45-year-old obsess woman presents complaining of menorrhagia with cramping pelvic pain, dizziness when standing, and rapid heart rate. Manual physical examination demonstrates multiple enlarged masses in her uterus. Blood workup reveals low RBCs [red blood cells] and hematocrit [% of RBC in a volume of blood], normal WBCs and platelets, and slightly elevated blood sugar level. U/S [ultrasound] of the abdomen and pelvis shows multiple fibroids [leiomyomas] of the uterine wall. Patient is admitted to the hospital with recommendation for hysterectomy. During the course of admission she peaks to the resident dietitian about a compulsive eating disorder and agrees to undergo therapy at the hospital’s weight loss clinic.

Using the information presented in these notes, select the principal diagnosis from the following:
Pelvic pain – female
Obesity
Anemia
Menorrhagia
Fibroid uterus

Using the process of elimination, because her bloodwork test results seem to be adequate, Anemia can be ruled out, as well as obesity. Although pelvic pain can be severe, it can be treated without hospitalization. A Fibroid uterus is an abnormality but does not always require treatment, but because of Menorrhagia, a Hysterectomy will be necessary in order to stop excessive bleeding and severe discomfort.
