A 14-year-old girl complained of fatigue and loss of stamina. Her appetite was marginal, as she was very conscious of maintaining her body weight at 96 pounds. Her monthly menstrual flow was always heavy and long from its onset at twelve years of age. Relevant laboratory findings included the following:
| Hematocrit (Hct) | 28% |
| Hemoglobin (Hgb) | 9 g/dL |
| Iron | 16 µg/dL |
| Bone marrow iron | Absent |
| Erythrocytes | Small and pale |
Suggested treatment included ferrous sulfate or ferrous gluconate for six months orally between meals, since food may reduce absorption. A well-balanced diet was also suggested, as well as a gynecological examination.
