In which situation would a postpartum patient require urgent medical evaluation?

The scenario that requires urgent medical evaluation is characterized by sudden severe headache, visual changes, or upper abdominal pain, as this combination of symptoms can indicate a serious condition known as postpartum preeclampsia or other complications such as HELLP syndrome. These conditions can pose significant risks to the mother and require immediate medical attention to ensure both her safety and that of the baby.

It's important to recognize that while headache and fatigue are common postpartum complaints, they do not typically warrant urgent evaluation unless they are part of a more alarming symptom set. Mild discomfort and feelings of being "blue" about parenting are also common in the postpartum period and generally do not signify acute medical issues, though they may warrant support and monitoring. Thus, the presence of sudden, severe symptoms is a clear indicator for urgent care.
