Postpartum fatigue and nonspecific symptoms are common complaints in family medicine and are often normalized as part of recovery. However, rare endocrine disorders such as Sheehan syndrome can present subtly and remain undiagnosed, potentially leading to prolonged morbidity. This case highlights the importance of considering endocrine causes in postpartum women with persistent symptoms.A 30-year-old woman presented to her family physician six months after delivery with persistent fatigue and generalized weakness that interfered with daily activities. Her delivery had been complicated by severe postpartum hemorrhage, requiring urgent management. Since childbirth, she reported inability to lactate, secondary amenorrhea and dizziness on standing. She denied symptoms suggestive of postpartum depression. Physical examination revealed low-normal blood pressure and mild bradycardia, with no neurological deficits or other remarkable findings. Based on her obstetric history and persistent multisystem symptoms, hypopituitarism was suspected, and further laboratory evaluation was performed. The results confirmed a diagnosis of Sheehan syndrome. Hormone replacement therapy was initiated, resulting in gradual improvement in fatigue, orthostatic symptoms, and overall functional capacity over subsequent months, allowing her to resume normal daily activities.Sheehan syndrome is rare in high-resource settings and often presents acutely. This case is notable for its subtle presentation with nonspecific postpartum symptoms. Literature on mild or insidious cases in primary care is limited. The case demonstrates the value of primary care in early recognition of rare conditions through careful assessment of postpartum women.Persistent postpartum fatigue, failure to lactate, and amenorrhea should prompt evaluation for Sheehan syndrome. Early recognition and management enable improved outcomes. Family physicians should maintain vigilance for rare endocrine disorders and consider structured postpartum assessment protocols.Sheehan syndrome results from ischemic pituitary necrosis following severe postpartum hemorrhage. Symptoms may include fatigue, hypotension, amenorrhea, lactation failure, and cold intolerance. Because these symptoms often overlap with normal postpartum changes, diagnosis can be delayed. Family physicians, through holistic assessment and longitudinal care, are well-positioned to detect early signs and initiate treatment.Sheehan syndrome can present subtly with nonspecific postpartum symptoms. Awareness in primary care, combined with obstetric history and systematic postpartum assessment, allows timely recognition, appropriate treatment, and improved patient recovery.
