Dual Diagnosis: Eating Disorders and Addiction

Eating disorders and addiction can become tangled together in ways that are difficult to see from the inside.

Someone may use a substance when they are feeling ashamed or to help manage stress, suppress appetite, and create distance from uncomfortable feelings about food and their body. 

Since some substances suppress appetite, substance use can then make eating disorder symptoms harder to manage, while the eating disorder continues creating reasons to use.

A dual diagnosis program can help someone look at both patterns at the same time. When one condition has started doing emotional work for the other, separating the pieces becomes an important part of recovery.

How Are Eating Disorders and Addiction Connected?

Eating disorders and substance use disorders often share some of the same emotional ground. They can have the same roots.

Research has connected the overlap with factors such as emotional regulation, stressful events, anxiety, and the use of substances to change appetite or cope with difficult feelings. People with eating disorders also experience substance use disorders at higher rates than the general population.

The connection looks different for everyone. Someone may use a stimulant to control appetite or energy. Another person may notice that substance use becomes strongest during periods when body image, anxiety, or the need for control feels especially difficult.

Eventually, it becomes hard to tell where one habit ends and the other begins.

That is why treating both the substance use and eating disorder, together, can be the only way to lasting change.

Types of Eating Disorders in Dual Diagnosis Care

Eating disorders can look very different from one another. They also cannot be identified by someone’s appearance alone.

Common eating disorders include:

• Anorexia Nervosa: Involves significant restriction of food intake, fear of weight gain, and disturbances in how someone experiences their body or weight. Anorexia can cause serious medical complications.
• Bulimia Nervosa: Involves repeated episodes of binge eating followed by behaviors intended to compensate for the food consumed. Shame and secrecy often become part of the cycle.
• Binge Eating Disorder: Involves recurring episodes of eating unusually large amounts of food while feeling unable to stop, often followed by guilt, distress, or shame.
• Other Specified Feeding or Eating Disorder (OSFED): Describes clinically significant eating disorder symptoms that cause distress or impairment but do not fit neatly within the full criteria for another specific eating disorder.

A diagnosis gives the treatment team useful information, but the name alone does not explain how the disorder is functioning in someone’s life.

How We Treat Eating Disorders and Addiction Together

When substance use has become connected to body image and emotional pain, treatment addresses the connections rather than approaching just a single symptom. 

At Serenity Grove, dual diagnosis care begins with an assessment of mental health, substance use, physical health, and current safety needs. Eating disorders can carry significant health risks, so the team must also determine whether someone needs additional medical stabilization or specialized eating-disorder support.

Mental health care for eating disorders may include:

• Cognitive Behavioral Therapy (CBT): Helps identify thoughts and behaviors that keep substance use and unhealthy patterns around food or body image going.
• Dialectical Behavior Therapy (DBT): Builds emotional regulation, distress tolerance, mindfulness, and skills for getting through difficult moments without immediately acting on an urge.
• Group Therapy: Creates room to talk honestly about addiction, shame, relationships, and recovery with other people doing similar work.
• Family Therapy: Helps families improve communication, understand patterns, set healthier boundaries, and become part of ongoing support.
• Trauma Therapy: Looks at experiences that may continue shaping body image, control, emotional safety, or substance use.
• Life Skills Training: Supports routines, stress management, communication, and daily functioning outside treatment.
• Meditation and Yoga Therapy: Gives people ways to slow down, reconnect with the body, and practice experiencing discomfort without immediately trying to escape it.
• Psychotherapy: Psychotherapy provided individual space to understand how the eating disorder and substance use developed and what keeps each pattern active.

The work of recovery becomes very personal. Because experience plays into how someone behaves, two people can have the same symptoms and diagnoses and need very different support.

Signs Someone May Have an Eating Disorder and Addiction

The overlap may be difficult to recognize because secrecy can surround both conditions.

Signs of an eating disorder and addiction may include:

• Becoming increasingly preoccupied with food, eating, weight, or body image
• Using alcohol or drugs to manage appetite, emotions, anxiety, or shame
• Hiding either eating behaviors or substance use
• Withdrawing from meals, relationships, or social activities
• Significant changes in mood or energy
• Feeling increasingly out of control around food, substances, or both
• Continuing either pattern despite physical or emotional consequences
• Organizing more of the day around eating behaviors, substance use, or recovering from them
• Noticeable changes in physical health or everyday functioning

Frequently Asked Questions

Can an eating disorder lead to addiction?

An eating disorder does not automatically cause addiction. However, some people begin using substances to manage appetite, anxiety, shame, trauma, or other feelings connected with disordered eating, and that pattern can eventually become difficult to control.

Can addiction make an eating disorder worse?

Yes. Substance use can intensify mood instability, impulsivity, nutrition problems, and physical health concerns while making eating patterns harder to understand and treat. Research also suggests that people living with both conditions may experience more complicated symptoms and recovery.

What does dual diagnosis treatment for eating disorders involve?

Dual diagnosis care looks at the eating disorder and substance use together. Treatment may include individual and group therapy, psychiatric assessment, family involvement, coping skills, trauma treatment, and medical evaluation based on the person’s needs.

Will I need medical monitoring during treatment?

It is possible. Eating disorders and substance use can both affect physical health, and some people need more medical monitoring or stabilization than others.

An assessment helps determine what can safely be treated at the current level of care and whether additional specialized medical or nutritional support is needed.

How long does treatment take?

There is no standard timeline for recovering from an eating disorder and addiction. Treatment length depends on physical health, symptoms, substance use, mental health, response to care, and the amount of support someone needs as recovery progresses.
