1. Allergy to Your Newborn (Pemphigoid Gestationis)
Pemphigoid gestationis is a rare condition that affects mothers typically in the mid to late stages of pregnancy. The condition presents with an itchy rash that begins to develop into a blister. The cause of this allergy is the woman’s skin reacting against itself, typically when a bit of placenta tissue finds its way into the bloodstream, paired with a woman’s increased hormones during pregnancy that tend to exacerbate the issue.
