Is the fiancée required to inform the suitor about having small hemorrhoids, even if he doesn't ask, knowing that he chose her for her religiosity?

Some scholars have considered hemorrhoids a defect that nullifies a marriage contract, due to the aversion and transmittable impurity they cause. It is stipulated that the suitor must be informed if the hemorrhoids cause aversion and their impurity is transmittable, unless they are temporary and recovery is expected soon.
