VILMA, a 46-year-old woman, was admitted to the Female Ward with recurring diarrhea. She had three full-term pregnancies in the past, but after her third, she developed post-partum hemorrhage, for which she was treated. As a result, she experienced lactation failure, amenorrhea, fatigue, weight loss, weakness, and hypothyroidism symptoms.

Physical examination revealed that she is thin-built (BMI=17 kg/m2), that her pulse is regular at 86 beats per minute, and that her blood pressure is 90/50 mmHg. The pubic and axillary hair were sparse, but the external genitalia were normal.
