PUPPP, or pruritic urticarial papules and plaques of pregnancy, is the most common pregnancy-specific skin condition, often causing significant discomfort for expectant parents.
What it is
This condition, sometimes called polymorphic eruption of pregnancy (PEP), is characterized by an itchy rash that typically emerges in the third trimester. It's almost exclusively seen in first-time mothers and those carrying multiples, like twins or triplets. The rash usually starts on the abdominal stretch marks, then might spread to the thighs, buttocks, and arms. A key distinguishing feature is that it commonly spares the belly button area. It's important to know that while PUPPP can be incredibly bothersome for you, evidence from sources like ACOG confirms it poses no harm or associated risks to your baby.
