Inflammation of the esophagus is known as esophagitis . Reflux of gastric acids from the stomach, infection, substances ingested (for example, corrosives ), some medications (such as bisphosphonates ), and food allergies can all lead to esophagitis. Esophageal candidiasis is an infection of the yeast candida albicans that may occur when a person is immunocompromised . As of 2014 [update] the cause of some forms of esophagitis, such as eosinophilic esophagitis , is not known. Esophagitis can cause painful swallowing and is usually treated by managing the cause of the esophagitis - such as managing reflux or treating infection.

Some see this as a call to change the conversation entirely, as Friedman suggests, others as evidence that Dove's message about beauty is important and necessary. An estimated 80 percent of American women feel dissatisfied with their bodies , and 81 percent of 10-year-old girls are afraid of becoming "fat." Can a series of ad campaigns really change institutionalized body hatred?
