Recovery doesn't require perfection, just presence

How We Treat Co-Occuring Disorders

Oasis Eating Disorders Recovery provides a specialized, integrated treatment model that simultaneously addresses disordered eating behaviors and co-occurring diagnoses. Upon admission, every individual receives a full psychiatric evaluation, which allows our multidisciplinary team to create a personalized treatment plan tailored to their unique emotional and clinical needs. We offer outpatient psychiatry to help manage medications and symptoms of other mental health conditions, ensuring that both the mind and body receive consistent, comprehensive support throughout the recovery process.

How Mental Health Can Contribute to Disordered Eating

Mental health conditions and eating disorders often influence one another. Anxiety, PTSD, depression, OCD, and other conditions can contribute to behaviors such as restriction, bingeing, purging, or rigid food rules as a way to cope with distress, regain a sense of control, or manage difficult emotions.

Common co-occurring conditions may include:

Anxiety Disorders: Worry, panic, or a need for control may become closely tied to food, weight, or eating routines.
Mood Disorders: Depression or bipolar disorder can affect motivation, appetite, energy, and engagement in recovery.
PTSD: Trauma symptoms may contribute to avoidance, emotional numbing, or disordered eating as a coping response.
OCD: Intrusive thoughts and compulsive behaviors can overlap with rigid food rules, checking, and ritualized eating.
Substance Use Disorders: Substance use and eating disorder behaviors may develop together as ways of coping with emotional distress.
Borderline Personality Disorder: Difficulties with emotional regulation and impulsivity can interact with bingeing, purging, or other eating disorder behaviors.

Small steps still move you forward

How Eating Disorders Can Affect Mental Health

The relationship also works in the other direction. Eating disorders and inadequate nutrition can affect mood, concentration, sleep, energy, emotional regulation, and the ability to think clearly. As symptoms become more severe, anxiety, depression, irritability, obsessive thinking, and social withdrawal may also become more difficult to manage.

This can occur across diagnoses such as anorexia nervosa, bulimia nervosa, binge eating disorder, ARFID, and OSFED.

Why We Treat Both Together

When an eating disorder and another mental health condition are reinforcing each other, treating only one can leave important parts of the problem unaddressed. At Oasis Eating Disorders Recovery, dual diagnosis care allows our team to work on nutritional rehabilitation, eating disorder behaviors, emotional health, and co-occurring symptoms within one coordinated treatment plan.

This integrated approach helps clinicians understand which symptoms are driving others, adjust treatment as needs change, and support recovery across both physical and mental health.

Integrated Treatment Options at Oasis

Choosing the right level of care is essential for building a sustainable foundation for wellness. We offer multiple structured programs that provide different intensities of support depending on a person’s specific needs and physical stability.

Partial Hospitalization Program (PHP): Often referred to as day treatment, this level provides daily structure and supervised meals for those needing the highest level of outpatient support.
Intensive Outpatient Program (IOP): This level allows for continued healing while stepping into more independence, offering therapy and nutritional guidance several days a week.
Outpatient Psychiatry: Provides ongoing support for managing both the eating disorder and co-occurring mental health conditions through psychiatric evaluations and medication management.

This isn’t the end of your story

Evidence-Based Care for Complex Mental Health Needs

For some clients, the eating disorder is closely tied to more significant mental health concerns such as trauma, severe anxiety, depression, OCD, or emotional instability. In these cases, treatment may place greater emphasis on therapist-led interventions and psychiatric support, while nutrition therapy remains an essential part of care.

Depending on the individual, treatment may include:

Cognitive Behavioral Therapy (CBT): Addresses thought patterns contributing to both eating disorder behaviors and mental health symptoms.
Dialectical Behavior Therapy (DBT): Builds emotional regulation and distress tolerance when intense emotions are driving harmful behaviors.
Nutrition Therapy: Supports nutritional rehabilitation while the clinical team addresses underlying psychological concerns.
Individual and Trauma-Focused Therapy: Provides more focused clinical work when trauma, anxiety, depression, or other conditions are significant barriers to recovery.
Family Therapy: Helps families understand both diagnoses and provide more effective support outside of treatment.

This flexibility is why dual diagnosis care cannot follow the same path for every client. The balance of nutritional, psychiatric, therapeutic, and experiential support should reflect the conditions that are having the greatest impact on recovery.

You can do it

Personalized Treatment Plans

At Oasis Eating Disorders Recovery, we believe that no two journeys are exactly the same, which is why we conduct intensive psychiatric evaluations upon admission. This allows our team to create a personalized treatment plan that reflects your unique history, challenges, and goals. We work closely with you to ensure that the therapies and interventions provided are the most effective for your specific situation. This collaborative process helps you feel more stable and supported as you navigate the complexities of your recovery.

In addition to traditional clinical work, we prioritize life skills and nutritional stability to help you maintain your progress post-treatment. Clients meet individually with a dietitian each week to work on meal planning and nutrition education, ensuring that their physical health is nurtured alongside their emotional growth.

By focusing on the whole person, we help you quiet the thoughts that keep you stuck and rediscover a life filled with meaning and connection. Our staff is dedicated to creating an environment where healing happens through compassionate care and expertise.

Frequently Asked Questions

What is dual diagnosis treatment for eating disorders?

Dual diagnosis treatment involves an integrated approach that simultaneously addresses an eating disorder and co-occurring mental health conditions like depression or anxiety. This ensures that the underlying emotional drivers are treated alongside the physical eating behaviors.

Do I need a formal diagnosis before starting the program?

No, you do not need a prior formal diagnosis to seek help at Oasis Eating Disorders Recovery. Our team provides comprehensive evaluations upon admission to identify your specific needs and create a personalized care plan.

Is dual diagnosis care more effective than standard treatment?

For individuals struggling with multiple conditions, integrated treatment is often more effective because it addresses the complex interactions between mental health and eating behaviors. Treating both issues together reduces the risk of relapse and promotes long-term emotional healing.

How does a registered dietitian help with dual diagnosis?

A registered dietitian provides nutritional therapy and customized meal planning to restore physical health and stabilize the body. They work closely with the clinical team to ensure that nutritional support aligns with the psychological goals of treatment.

Can I attend treatment while staying at home?

Yes, we offer outpatient levels of care, such as PHP and IOP, which provide structured support during the day while allowing you to return home in the evening. This structure helps you practice new coping skills in your actual daily environment.

Are family members involved in the treatment process?

Yes, we believe healing is a team effort and often incorporate family therapy to support emotional recovery. Family involvement helps improve communication and creates a more supportive environment for the individual’s long-term success.
