What Is PAH?
"PAH is paradoxical adipose hyperplasia," says Dr. Bruce Katz of JUVA Skin and Laser Center in New York City. "It activates the stem cells to grow new fat in the area treated, which is more dense and tighter, making it harder to get rid of."
"PAH is most common in the treatment areas," explains Dr. Katz. "If [Evangelista] had CoolSculpting on her abdomen, back, bra area, inner thighs, and chin, it would certainly seem like she has PAH all over her body."
Is PAH as Rare as We Think?
The three doctors InStyle spoke to for this story believe that numerous PAH cases have gone underreported, especially Dr. Katz. "I have treated quite a few of these PAH cases throughout the years successfully, and think these types of cases have gone unreported," he says, adding that his PAH case counts have been "consistent" throughout the years and that "the side effect of CoolSculpting has always been there."
