Exposure therapy is a type of therapy used to treat eating disorders, phobias, and anxiety. It is typically used as part of a treatment plan that includes other types of therapy for eating disorders, such as acceptance and commitment therapy (ACT) and cognitive behavioral therapy (CBT).
Exposure therapy is an evidence-based treatment modality used to treat phobias, fears, and anxieties. When someone is terrified of something, they tend to avoid their fear, whether it’s a situation, behavior, person, or object. Avoiding their fear can help reduce anxiety symptoms in the short term, but in the long run, the phobia magnifies. (1)
Exposure therapy breaks the cycle of fear and avoidance by gradually and safely exposing the patient to their phobia in a controlled, monitored setting. The idea is that slowly, over time, exposure can decrease feelings of anxiety and fear, thus reducing avoidance.1
Exposure therapy can help eating disorder patients in a few ways, including:1
Many people with eating disorders have extreme fears related to their disordered eating behaviors, whether it be eating a certain amount, eating a particular food, looking in the mirror, or avoiding a behavior like compulsive exercise. Exposure therapy for eating disorders involves confronting their fears and incorporating them into the patient’s everyday life under the guidance of a therapist or psychologist.
Exposure therapy for eating disorders like anorexia nervosa, bulimia nervosa, avoidant restrictive food intake disorder (ARFID), and binge eating disorder involves exposing patients to their fear, which may initially cause a spike in anxiety as they begin to face their fears. Still, over time, the patient will typically adapt to the feared situation and experience a reduction in anxiety.
Moreover, exposure therapy can help eating disorder patients develop new associations between their fears and outcomes. After exposure to their fear, they may learn that the outcome is not what they had expected. Developing tools to safely manage if the feared outcome does occur can also be part of this process.2
At Within Health, we tailor our treatment plans to meet the unique needs and challenges of each patient, and that includes creating thoughtful and individual exposures to support our patients. This includes support around exposures to new or feared foods during programming.
Our movement groups are also exposure therapy groups. Some eating disorder patients are afraid of moving their bodies or exercising because this brings about awareness of their bodies. Exposure work may involve doing small increments of movements if nutritional intake is appropriate. We also individualize this movement exposure by finding movement that brings our patients joy or involves something they’d like to learn, such as dance.
Alternatively, some movement exposure groups may involve the cessation of movement. This is typically for patients with a history of compulsive exercise or exercise addiction. For example, if a patient typically engages in a rigid exercise regime, they may be asked to take more rest days or change the duration and intensity of their workouts, which can ultimately help them to overcome their fear of not exercising.
Exposure therapy may be used to treat many different eating disorders, including:2
Additionally, exposure therapy may be used to treat eating disorder patients with co-occurring mental health conditions, such as:1
Disclaimer about "overeating": Within Health hesitatingly uses the word "overeating" because it is the term currently associated with this condition in society, however, we believe it inherently overlooks the various psychological aspects of this condition which are often interconnected with internalized diet culture, and a restrictive mindset about food. For the remainder of this piece, we will therefore be putting "overeating" in quotations to recognize that the diagnosis itself pathologizes behavior that is potentially hardwired and adaptive to a restrictive mindset.
There is some evidence that exposure therapy for eating disorders can help reduce anxiety and improve disordered eating symptoms, but large randomized controlled trials isolating exposure therapy from other modalities, such as cognitive behavioral therapy or interpersonal psychotherapy, have yet to be conducted.3
Research indicates that mirror exposure on its own or within the context of CBT can increase body satisfaction. It has also been shown to help reduce a patient’s response to binge and purge cues. Direct exposure to feared foods has been shown to increase food intake and reduce anxiety, but more research is needed.3
Many different eating disorder treatment settings integrate exposure therapy into their treatment plans, such as:
Whether your treatment program officially refers to it as exposure therapy or not, eating disorder treatment often inherently involves exposure to things that patients are fearful of, such as eating certain foods, moving or not moving their bodies, refraining from purging behaviors, looking in the mirror, and coping with body changes. A crucial part of eating disorder treatment is facing these fears in a trusted, safe environment under the care of treatment professionals. Confronting these fears can reduce avoidant behaviors in the future and, ultimately, allow individuals to recover from their eating disorders and live healthier and happier lives.
