Someone with bulimia nervosa may show specific physical signs of the disorder in their face. Regular vomiting may lead to swollen salivary glands which can cause the face and neck to look puffy, a phenomenon sometimes referred to as “bulimia face” or “bulimia cheeks.” They may also have discolored, brittle teeth or painful sores in the corners of their mouth. Intense vomiting may also result in broken veins in the face, which may be visible to observers. Once the individual has stopped purging, puffiness and mouth sores should decrease within a few weeks. Some changes to teeth, however, may not be reversible, although a dentist can help repair broken teeth or fill cavities that resulted from frequent purging.
