A serum pregnancy test is negative and an MRI scan of her pituitary gland is normal. What is the probable diagnosis? Explain.

Answer 1

The amenorrhea in the presented case is most likely caused by work-related stress. Currently, the patient has lost weight, which has been demonstrated to cause amenorrhea. The hormonal tests that are presented fall within normal fluctuations, which rules out hormanal imbalances as the primary cause. Ideally, the condition is brought about by work related stress and exacerbated by the weight loss.
