​What is Pathology - Is atrophy usually a sign of disease? 
Physiologic or pathologic atrophy can occur. The uterus shrinks after pregnancy, which is an example of physiologic atrophy. It is normal for the thymus to atrophy (involve) during adolescence or early adulthood. The uterus shrinks when the ovaries are removed, although this can be restored with hormone therapy. Thymic involution is permanent.
