In an interview with Healio, B. Timothy Walsh, MD, a professor of psychiatry at Columbia University, discusses the prevalence of eating disorders in the U.S., the factors that can trigger them, and the most effective ways for healthcare providers and loved ones to support those affected. Walsh emphasizes the importance of building trust, providing education, and approaching the issue with empathy.

Why it matters

Eating disorders, which primarily affect women and often emerge in adolescence and early adulthood, can have serious physical and mental health consequences. Understanding the nuances of these conditions and how best to address them is crucial for improving outcomes and reducing stigma.

The details

According to Walsh, the number of Americans currently affected by the three major eating disorders - anorexia nervosa, bulimia nervosa, and binge eating disorder - is likely around 3 million. While there are no clear seasonal patterns, certain events and transitions, such as going away to school or the holidays, can serve as triggers for those vulnerable to eating disorders. Walsh notes that the disorders tend to develop in response to stress, as individuals may turn to restrictive eating or binge-purge behaviors as a way to feel more in control. He emphasizes the importance of healthcare providers being proactive in screening for eating disorders, as patients may initially present with other complaints.

“Eating disorders are often associated with feelings of shame. For many folks with eating disorders, the relationship with the disorder is ambivalent. There are facets of it that they may find rewarding or comforting.”
