Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by intrusive, persistent thoughts (obsessions) and repetitive behaviours or mental acts (compulsions) that are performed to help relieve anxiety and distress. Research is starting to show that there is a connection between food, OCD, and eating disorders. While they may seem to be different conditions, OCD and eating disorders have similar cognitive, behavioural, and personality characteristics.
When it comes to food, OCD can present significant barriers to eating well and having a good relationship with food due to obsessions and compulsions related to food preparation and consumption. For some people, this could develop into an eating disorder.
In this blog post, we will explore the relationship between food, OCD, and eating disorders to help you better understand how they’re connected, as well as the treatment options available for each condition.
The Intersection of OCD and Eating Disorders
Research has shown that there is a significant overlap between OCD and eating disorders, with many people being diagnosed with both conditions. It’s thought that this is due to shared personality factors such as perfectionism and neuroticism (a personality trait in which a person is prone to frequently changing emotions and increased levels of anxiety and distress).
Impact on Eating Habits
OCD can affect eating habits in several ways. People with OCD may find themselves preoccupied with cleanliness and hygiene, which may lead to excessive handwashing and a reluctance to touch or eat certain foods. This can result in restrictive eating patterns, which could develop into an eating disorder if left unchecked.
Anxiety-Induced Dietary Changes
Anxiety is a hallmark of OCD, and many people with OCD experience increased anxiety levels around mealtimes. Some people may develop specific rituals or compulsions related to food preparation and consumption. For example, a person may count how many mouthfuls of food they have chewed according to a “correct” number. These rituals can significantly disrupt normal eating patterns and impact overall nutrition.
OCD and Obsessive and Compulsive Behaviours
With OCD, obsessive thoughts often revolve around cleanliness, symmetry, or fears of harm, while with eating disorders, a person may experience obsessive thoughts related to body image, weight, or the need to control their food intake.
This can lead to compulsive behaviours such as body checking (the act of scrutinizing oneself in the mirror or on the scale), counting calories, or purging after a binge. These behaviours are aimed at relieving anxiety and gaining a sense of control, like OCD rituals.
Anxiety and Perfectionism
Anxiety and perfectionism are common features in both OCD and eating disorders. People with OCD often experience extreme anxiety when their rituals are interrupted or if they are unable to perform them. With eating disorders, perfectionism can drive the pursuit of an idealized body image due to fear of not measuring up to societal standards.
Triggers and Coping Mechanisms
Stress and emotional triggers play a key role in both OCD and eating disorders. For example, high levels of stress or emotional distress can intensify obsessions and compulsions in OCD. These same factors can trigger episodes of binge eating or purging in people with eating disorders. These behaviours may serve as coping mechanisms to manage stressful emotional states.
Treatment of OCD and Eating Disorders
While OCD and eating disorders often occur together, they often require different types of treatment.
Treatment for OCD
Cognitive Behavioural Therapy (CBT), particularly a specialized form called Exposure and Response Prevention (ERP), is the gold standard for treating OCD. ERP involves exposing a person to their obsession and preventing the compulsive behaviours that follow. Over time, this can help reduce the anxiety associated with the obsessions.
In some cases, medication may also be needed to treat OCD. Selective serotonin reuptake inhibitors (SSRIs) are commonly used. For some people, a combination of CBT and medication is needed to manage the condition.
If ERP and medications are not enough to help a person gain control of their OCD symptoms, more intensive levels of care are available. They include outpatient programs, day programs, residential treatment, or inpatient treatment.
Treatment for Eating Disorders
There are several types of eating disorders, including anorexia nervosa, bulimia nervosa, and binge-eating disorder. Treatment approaches vary depending on the type of eating disorder but commonly involve a combination of medical management, psychotherapy, and nutritional counselling. In some cases, medications and hospitalization or residential treatment may be required.
Final Thoughts
OCD and eating disorders are complex conditions that require comprehensive treatment. People with OCD and eating disorders should work closely with a healthcare team, including a psychiatrist, therapist, and a registered dietitian, to create a holistic treatment plan that addresses all facets of their condition.
