A 35-year-old woman presented with fatigue, weakness, and weight loss. She had a history of postpartum hemorrhage following her last delivery, requiring blood transfusions. Physical examination revealed pallor, hypotension, and decreased axillary hair. Laboratory tests revealed low levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4), as well as low levels of cortisol. Additionally, the patient had low levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), leading to amenorrhea. A diagnosis of Sheehan syndrome is made. Why is a steroid emergency card recommended for this patient?
