Is There A Link Between OCD And Eating Disorders?
Obsessive-compulsive disorder (OCD) and eating disorders often appear together, complicating diagnosis and treatment. Individuals with OCD may develop specific rituals around food, which may lead to or worsen eating disorders. For example, someone with anorexia might obsessively count calories or exercise excessively, behaviors also seen in OCD. The overlapping signs of these disorders can make seeking appropriate treatment a priority.
What is obsessive-compulsive disorder?
Obsessive-compulsive disorder is a mental health condition characterized by unwanted, intrusive thoughts, also known as obsessions. These obsessions are often linked to repetitive behaviors, known as compulsions, which are done to reduce anxiety or prevent a feared event.
OCD was previously classified under anxiety disorders but now stands as its own category in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), alongside conditions like body dysmorphic disorder. This change from the anxiety disorder category to its own unique focus highlights that OCD involves elements beyond anxiety, like specific patterns of thought and behavior.
Symptoms of obsessive-compulsive disorder (OCD)
The symptoms of OCD include the following:
- Obsessions: Obsessions are persistent, unwanted thoughts, urges, or images. Common obsessions include fears about contamination, harm, or a lack of symmetry.
- Compulsions: Compulsions are repetitive behaviors or mental acts that a person is driven to perform. Examples include excessive cleaning, checking, or counting.
People with OCD may struggle with daily routines. The compulsions can take up a significant amount of time, interfering with personal, social, and academic life.
The connection between OCD and eating disorders
People with OCD typically experience repetitive thoughts and compulsive behaviors that can also be seen in eating disorders. In some cases, overlapping symptoms of OCD and eating disorders may affect how treatment is personalized.
Research findings on the link between OCD and eating disorders
Studies show a strong connection between eating disorders and OCD. For instance, up to 44% of individuals with anorexia nervosa may also have OCD symptoms. This high rate indicates that eating disorders and OCD often occur together and share similar traits.
There's a strong link between anorexia nervosa and OCD. Research shows that many of the genetic factors for these conditions are shared. If a person has genes that make them more likely to have OCD, they are also more likely to have anorexia nervosa, and vice versa.
In addition, research has found that people with OCD and eating disorders use more glucose (a type of sugar) in their brains. Therefore, the brains of people with OCD and eating disorders might work in similar ways. Activities like frequent hand washing or strict food rules could also come from similar brain patterns.
Shared traits: Obsessions, compulsions, and eating behaviors
People with eating disorders may have obsessive thoughts about food intake, body weight, and body image, similar to OCD obsessions. Repetitive behaviors in OCD, like checking and washing, may mirror the ritualistic behaviors seen in anorexia nervosa and bulimia nervosa. For example, someone with anorexia may obsessively count calories, similar to how someone with OCD might check their locks multiple times. Both disorders involve behaviors that reduce anxiety but can become highly disruptive.
OCD symptoms and eating disorders may feed into each other, creating a difficult cycle to break. You may see compulsive behaviors related to eating and body image, further linking the two conditions.
Co-occurrence of OCD and eating disorders
The high rate of co-occurrence between OCD and eating disorders shows the deep relationship between these conditions. Some may find recognizing the prevalence of co-occurrence between these two conditions helpful in better addressing them.
Prevalence rates of co-occurring conditions
The challenges in diagnosing OCD and an eating disorder
Diagnosing OCD alongside an eating disorder may present different challenges. Both conditions may share symptoms, making it difficult to distinguish between them. Another challenge arises from the overlap in behavioral patterns. Individuals with OCD may have ritualistic eating behaviors similar to those seen in eating disorders. They might eat foods in a specific order or with certain textures or ingredients.
Healthcare professionals gather a detailed history and use specific guidelines to accurately identify an eating disorder. Individuals may be asked to pay close attention to the exact nature and frequency of symptoms. Some providers might ask them to keep a diary about their habits and behaviors.
How OCD and co-occurring eating disorders are managed
Successfully managing OCD and eating disorders may involve different methods. OCD and eating disorder treatment plans often include therapy, support groups, and self-care practices.
Therapy
Mental health professionals often use cognitive-behavioral therapy (CBT) to treat OCD and eating disorders. This type of therapy focuses on changing negative thought patterns and behaviors.
Exposure and response prevention (ERP), a type of CBT, may help patients face fears that may be causing certain eating behaviors to arise at certain moments. Another approach is dialectical behavior therapy (DBT), which may help patients manage emotions and practice mindfulness. Therapy sessions can be individual or group-based.
Medication management
Medication may help individuals manage the symptoms of OCD and some eating disorders. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed for OCD. In some cases, doctors might prescribe antidepressants or anti-anxiety medications for people with co-occurring eating disorders and depression or anxiety. Specific medications are also sometimes prescribed to treat bulimia, binge eating disorder, and other eating disorders. These medications are sometimes used alongside therapy to provide better outcomes in some eating disorders. However, the effectiveness and benefits of the intervention are analyzed by a doctor on a case-by-case basis.

Nutritional counseling for an eating disorder
Nutritional counseling may be a part of treatment plans for eating disorders, especially when they co-occur with OCD. Dietitians can work with patients to develop balanced eating habits and improve their relationship with food. Individualized meal plans may help ensure individuals get the nutrients they need. In addition, nutritional counseling may help clients identify misconceptions about food and body image. Nutritional goals recommended by a provider are often realistic and sustainable, allowing for long-term recovery and stability.
Support groups for obsessive-compulsive disorder and eating disorders
Support groups may provide a sense of community for individuals struggling with OCD and eating disorders. These groups may be led by mental health professionals or peer-led and participants cay learn helpful coping strategies in a group setting where others face similar challenges. Online support groups may also be available, providing flexibility for those who cannot attend in person.
Self-care practices
Mental health providers often recommend self-care practices for managing OCD and co-occurring eating disorders at home. Regular exercise (within moderation), mindfulness, and stress reduction techniques may help people manage symptoms. In addition, individuals may find that certain activities, such as journaling, meditating, or taking a walk, help them manage symptoms of OCD and eating disorders. Individuals can work with a therapist to devise a consistent routine that includes balanced meals, sleep, and relaxation.
When to seek help for OCD and an eating disorder
Recognizing when to seek help for OCD and an eating disorder may be difficult for some. However, when obsessions and compulsions interfere with daily life or thoughts about food, body image, or rituals consume a lot of time, seeking help may be advised. Sudden weight changes or extreme dieting may also signal the need for professional help.
Physical health can quickly decline, making early intervention important. Shame, guilt, and isolation may accompany these disorders. If you experience these emotions frequently, a mental health specialist may be able to offer the support you need. People with eating disorders may also benefit from speaking to a doctor, as eating disorders often have severe health risks.
Seeking help can involve several steps:
- Reaching out to a mental health professional who specializes in both OCD and eating disorders
- Asking a primary care physician for a referral to experts in these fields
- Talking to a doctor about your physical health
You can also look for treatment centers or specialists. Organizations like the National Eating Disorders Association (NEDA) and Eating Recovery Center provide resources and may guide you to the right professionals.
Alternative support options
Some people with OCD and eating disorders may find online support to be a lifeline. Online therapy platforms like BetterHelp often offer flexible scheduling and allow individuals to connect with therapists on their own time. Another potential benefit of online therapy is accessibility. This form of therapy often removes the need to travel, making it possible for individuals to find specialists even if they live in remote areas. This option may be particularly helpful for those who may not have local resources that meet their unique needs.
Research supports the effectiveness of online therapy for mental health challenges, including OCD and other obsessive-compulsive disorders. One study looked at how well online therapy works for treating OCD and body dysmorphic disorder in regular healthcare settings. Researchers found that 49% of people with OCD and 69% of those with body dysmorphic disorder got better with this treatment. Most people finished the therapy, with 87% in the OCD group and 78% in the BDD group reporting high satisfaction.
Takeaway
Is OCD associated with eating disorders?
Obsessive-compulsive disorder (OCD) and eating disorders can co-occur, meaning that an individual can have both an eating disorder and OCD at the same time. Research suggests that those with eating disorders tend to have a higher prevalence of obsessive-compulsive disorder and vice versa. These two disorders can be treated with cognitive behavioral therapy (sometimes mistakenly called “cognitive behavior therapy”) and other methods, such as exposure therapy, to specifically address the OCD part of the equation.
Therapy can help individuals address both ego-syntonic and ego-dystonic OCD symptoms. (Ego-syntonic symptoms can be described as those that align with one’s values and beliefs, while ego-dystonic symptoms go against one’s core sense of self.) When those with OCD share their thought processes and behaviors with a therapist, it can be challenging but ultimately beneficial.
To learn about anorexia nervosa, one of the most common eating disorders, the 2013 article “Nothing tastes as good as skinny feels: the neurobiology of anorexia nervosa” by Walter H. Kaye, sometimes referred to as “Kaye WH,” may be helpful. The journal European Eating Disorders Review may also be a valuable resource.
Do people with OCD have problems with food?
While not everyone with obsessive-compulsive disorder has problems with food, some do. For example, some people living with OCD may have food-related obsessions or distressing thoughts that lead them to eat their food in a certain order, cut it into tiny pieces, or avoid specific foods due to texture or other reasons. When eating foods related to their obsessions, they may experience a compulsion to eat in a ritualistic way or engage in specific behaviors to temporarily relieve the anxiety associated with the obsessive thoughts.
Do eating disorders and OCD go hand-in-hand?
OCD and eating disorders don’t always co-occur, but statistics suggest that people with eating disorders have a higher risk of also developing OCD, and those with OCD have a higher risk of experiencing eating disorders. It’s thought that shared personality traits between the disorders, such as perfectionism, may contribute to their co-occurrence. In some cases, it may seem like one disorder brings on the development of the other. When one disorder co-occurs with the other, it can make diagnosis and treatment more challenging. Both mental health disorders may also co-occur with affective disorders like depression.
Eating disorders may also go hand-in-hand with body dysmorphic disorder due to similar cognitive distortions, their shared focus on physical appearance, and frequent body-checking or mirror-checking, although there are key differences between them. Eating disorders like anorexia nervosa and bulimia nervosa often stem from a fear of gaining weight, whereas body dysmorphic disorder may be focused on any physical feature that a person believes to be flawed. This co-morbidity can sometimes be difficult to address, but effective treatment options are available.
Are people with OCD picky eaters?
Some people with OCD may be picky eaters, but this isn’t always the case. Symptoms of obsessive-compulsive disorder can often be relieved through OCD treatment, which usually involves cognitive behavioral therapy (CBT) or exposure and response prevention (ERP) with an OCD specialist.
What medication is used for OCD eating disorder?
Only a psychiatrist or another licensed medical professional can prescribe medication for obsessive-compulsive disorder, eating disorders, and other mental health conditions. The specific medications prescribed for these disorders often vary from person to person.
What does food OCD look like?
“Food OCD,” while not a clinical term, may refer to obsessive-compulsive disorder symptoms that center around food. For example, an individual with OCD may have a fear of contamination that extends to produce items. They may fear consuming mold and thus avoid certain foods they deem as potentially unsafe to consume.
What foods should you avoid if you have OCD?
If you have OCD, it may be helpful to limit or avoid alcohol, caffeine, and ultra-processed foods, as they may exacerbate obsessive-compulsive disorder symptoms.
What are the eating habits of people with OCD?
The eating habits of people with OCD can vary greatly. Some individuals with obsessive-compulsive disorder may have typical eating patterns, particularly if their obsessions and compulsive actions are not related to food. However, some people with OCD may avoid certain foods or engage in time-consuming rituals while eating.
What percentage of people with eating disorders have OCD?
It’s estimated that between 11% and 69% of those with eating disorders also have obsessive-compulsive disorder. They may develop OCD first, the eating disorder may come first, or both disorders may seem to develop at the same time.
Does OCD cause weight gain?
In general, OCD is not associated with weight gain. However, some research suggests that there could be a link between compulsive behavior and obesity.
