OCD and Bulimia: Link Between These Disorders

OCD and Bulimia: Link Between These Disorders

Obsessive-Compulsive Disorder (OCD) and Bulimia Nervosa are two eating disorders that have been studied by scientists for decades. But, recently, more research has come to light that suggests there may be a link between these two disorders. In this blog post, we will explore the relationship between OCD and bulimia and how to recognize the signs of each disorder. We’ll also discuss potential treatments for both OCD and bulimia if you or someone you know is struggling with either of these mental health issues.

What is OCD?

What is OCD?

There is a lot of overlap between OCD and bulimia, and many experts believe that the two disorders are linked. Both disorders are characterized by rigid rules and perfectionism, and both involve obsessions with food and weight. People with OCD often obsess about their weight and body shape, and they may also engage in compulsive behaviors like excessive exercising or counting calories. People with bulimia often have OCD-like features, such as compulsively checking their weight or body shape in mirrors.

There is evidence that people with OCD are more likely to develop bulimia and vice versa. One study found that nearly half of the people with OCD also had symptoms of bulimia. Another study found that people with OCPD (a similar disorder to OCD) were more likely to develop bulimia over the course of their lifetime.

It’s not entirely clear why the link between OCD and bulimia exists, but it’s likely that the two disorders share some underlying causes. Both disorders may be caused by neurochemical imbalances, genetic factors, or psychological factors like trauma or stress.

What is Bulimia?

Bulimia is an eating disorder that is characterized by binge eating followed by purging. Binge eating is defined as eating a large amount of food in a short period of time. Purging is typically done by vomiting, but can also be done by using laxatives or diuretics. Bulimia usually occurs in individuals who are obsessed with their weight and body image. These individuals often have a history of dieting and may be underweight or overweight. Bulimia can lead to serious health problems, including electrolyte imbalance, dehydration, and gastrointestinal problems.

The Link Between OCD and Bulimia

The Link Between OCD and Bulimia

There is a strong link between OCD and bulimia. People with OCD tend to be perfectionists and have a hard time letting go of things. This can lead to an obsession with food and weight, which can trigger bulimic behaviors. Bulimia is often a way for people with OCD to try to gain control over their lives. They may feel like they are not good enough or that they need to be perfect in order to be accepted. This can lead to restrictive eating behaviors and compulsive exercise, as well as purging through vomiting or using laxatives.

Those with OCD may also become preoccupied with thoughts and behaviors related to food, such as counting calories or obsessing over the size of meals. This can lead to an eating disorder in which the person feels compelled to eat large amounts of food in a short period of time, followed by purging. Bulimia can be a sign that someone is struggling with underlying issues, such as anxiety or depression, which may be linked to OCD.

Is It Common For People To Have OCD and Bulimia?

Is It Common For People To Have OCD and Bulimia?

Yes, it is common for people to have OCD and bulimia. In fact, research has found that the two disorders often occur together. One study found that nearly half of all people with OCD also had bulimia.

The link between OCD and bulimia may be due to the fact that both disorders involve an obsession with food and weight. People with OCD may be obsessed with the calories in food and the fat content, while people with bulimia may be obsessed with the idea of being overweight. Both disorders can lead to restrictive eating habits and an intense fear of gaining weight.

Some people who have both OCD and bulimia may also have body image issues, feeling insecure about their appearance or size. Treatment for both disorders is important to help manage symptoms and reduce the risk of developing related health problems.

What Causes Both OCD and Bulimia?

There are a number of potential causes for these disorders. For OCD, possible causes include genetics, brain chemistry, and environmental factors. Bulimia may be caused by a combination of genetic, biochemical, social, and psychological factors.

OCD is thought to have a strong genetic component. Family studies have shown that people with first-degree relatives (parents, siblings, or children) with OCD are more likely to develop the disorder themselves. This suggests that there may be a heritable component to OCD.

Brain chemistry may also play a role in the development of OCD. Studies have found that people with OCD tend to have higher levels of the neurotransmitter serotonin in their brains. This abnormality in brain chemistry may contribute to the intrusive thoughts and repetitive behaviors characteristic of OCD.

Environmental factors may also trigger or worsen OCD symptoms. Stressful life events (such as the death of a loved one or divorce) can trigger obsessions or compulsions. Additionally, people who grew up in environments where cleanliness and order were highly emphasized may be more susceptible to developing OCD later in life.

Social and psychological factors may also contribute to the development of bulimia. People who experienced childhood trauma or abuse, as well as those who have low self-esteem or body image issues, may be more likely to develop bulimia. Additionally, living in a society where thinness is valued can lead some individuals to turn to disordered eating behaviors in an attempt to achieve the ideal body type.

Treatment Options

Treatment Options

There are many similarities between these disorders, which is why they are often comorbid, or co-occurring. The most effective treatment for both disorders is a combination of medication and therapy.

  • Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed type of medication for OCD and Bulimia. These drugs increase levels of serotonin in the brain, which helps to alleviate symptoms. Common SSRIs used to treat OCD and Bulimia include fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil).
  • Cognitive behavioral therapy (CBT) is the most common type of therapy used to treat OCD and Bulimia. CBT focuses on changing negative thinking patterns and behaviors. It teaches patients how to identify their triggers and how to cope with them in a healthy way.
  • Other types of therapy that can definitely help in treating OCD and Bulimia include dialectical behavior therapy (DBT), interpersonal therapy (IPT), and acceptance and commitment therapy (ACT).

It is important to remember that treatment for these disorders should be tailored to the individual, as everyone’s experience is unique. It is also important to note that recovery can take a long time, so patience and dedication are key in managing these disorders.

OCD and Bulimia can be difficult disorders to live with, but there is hope for recovery. With the right combination of medication and therapy, many people with OCD and Bulimia are able to lead happy and productive lives.


In conclusion, OCD and bulimia are two disorders that are linked together in many ways. It is important to be aware of the relationship between these conditions so that you can better understand your own symptoms and seek appropriate treatment if necessary. Both OCD and bulimia can be treated successfully with therapy, medication, lifestyle changes, or a combination of all three. If you think you may have either disorder it is important to speak with a mental health professional who can assess your situation and provide the best possible care for your specific needs.
