Eating Disorder Treatment

Eating disorders have one of the highest death rates of any mental illness. Over a lifetime, they affect an estimated 9% of the U.S. population — about 28.8 million Americans — across anorexia, bulimia, binge-eating disorder, ARFID, and OSFED. They also frequently occur alongside substance use, anxiety, depression, and trauma. That’s why we built our Eating Disorder program inside a fully licensed behavioral health center, instead of running it as a separate, stand-alone service.

Alyssa Mueller, CADC II — Clinical Director

Every client who joins this program works with a Certified Eating Disorder Specialist (CEDS), a Registered Dietitian, and a Nutritionist — all on staff, working from one shared treatment plan.

This page covers who the program is for, the conditions we treat, the team you'll work with, and how care fits into our continuum, from PHP through outpatient.

We accept most PPO insurance providers.

Conditions we treat

Small plate with a modest portion of food representing restrictive eating

Anorexia Nervosa

This involves eating far less than the body needs, an intense fear of gaining weight, and a distorted view of one’s own body weight or shape. We treat both subtypes — restricting, and binge-eating/purging — and work closely with medical providers when weight restoration, electrolyte monitoring, or cardiac clearance is needed before starting treatment at our level of care.

Bipolar Disorder Treatment

Bulimia Nervosa

This involves repeated binge eating followed by behaviors meant to “undo” it — self-induced vomiting, misusing laxatives or diuretics, fasting, or excessive exercise. Treatment focuses on stabilizing the binge-purge cycle, monitoring for medical effects like electrolyte imbalances and dental damage, and using CBT-E to address the thinking patterns that drive the cycle.

Binge Eating Disorder (BED)

This involves repeated episodes of eating unusually large amounts of food, along with a feeling of losing control and significant distress — typically without the “undoing” behaviors seen in bulimia. BED is the most common eating disorder in the U.S., and it’s often accompanied by depression, anxiety, and substance use.

ARFID (Avoidant/Restrictive Food Intake Disorder)

This involves restrictive eating driven by low interest in food, sensory sensitivities, or fear of something bad happening (like choking) — not by body image concerns. ARFID often shows up in adolescents and adults with neurodevelopmental conditions, a history of GI issues, or food-related trauma. Our nutrition team is trained in gradual food exposure and sensory-based nutrition planning.

OSFED — Other Specified Feeding or Eating Disorder

This category includes atypical anorexia, purging disorder, night eating syndrome, and other patterns that don’t fully meet the criteria for another diagnosis. OSFED is common and clinically serious, but it’s often under-treated because it doesn’t match the popular image of what an eating disorder looks like. We treat OSFED with the same clinical depth as any other diagnosis.

Your Clinical & Nutrition Team

Every client’s care plan is built and reviewed by a coordinated team — not a single provider working alone.

CEDS-Certified Clinician

A Certified Eating Disorder Specialist leads your therapy plan and coordinates the rest of the team, using CBT-E, DBT, and FBT as appropriate.

Registered Dietitian (RD/RDN)

Handles meal planning, nutrition education, and structured meal support, using an "all foods fit" approach and working closely with your medical labs.

Nutritionist

Provides hands-on support with grocery planning, cooking, and food-related challenges, both inside and outside program hours.

Psychiatric Provider

Manages medication for co-occurring depression, anxiety, OCD-spectrum conditions, and ADHD — with attention to how malnutrition can affect how medications are absorbed and processed.

Case Manager

Coordinates with your primary care doctor, medical specialists (cardiology, GI, endocrinology), and any outside therapists you're already working with.

Family Program

Loved ones can join Connections, our family program that meets three times a week and teaches families how to support recovery without becoming the "food police."

Evidence-Based Treatment Model

Our therapy approach uses the treatments with the strongest research support for eating disorders in both teens and adults:

CBT-E (Enhanced Cognitive-Behavioral Therapy)

currently the top-recommended therapy for adults with bulimia, binge eating disorder, and OSFED, and a strong option for many people with anorexia

Family-Based Treatment (FBT / "Maudsley")

the first choice of treatment for teens with anorexia, and increasingly used for teen bulimia

Dialectical Behavior Therapy (DBT) skills

for clients who struggle to manage intense emotions or have a history of self-harm

Trauma-focused therapy (CPT, EMDR)

used when past trauma is contributing to the eating disorder

Exposure-based work

for ARFID, and for avoidance related to body image or mirrors

"The goal is not a number on a scale. The goal is a life that no longer runs on food rules."

Structured Meal Support & Nutrition

Meals are part of treatment, not a break from it. Clients eat supported meals and snacks during program hours, approached the same way we’d approach any other challenge — with a clinician there, skills practiced in the moment, and a debrief afterward.

Our Registered Dietitian and Nutritionist build individual meal plans that:

When Co-Occurring Substance Use Is Part of the Picture

About 50% of people with an eating disorder also develop a substance use disorder at some point — roughly five times higher than the general population. Wavecrest is licensed for dual diagnosis care, which means we can treat both conditions together, in one program, with one care team and one treatment plan.

Levels of Care & Medical Eligibility

We offer eating disorder treatment at the Partial Hospitalization Program (PHP), Intensive Outpatient Program (IOP), and Virtual IOP levels.

Because eating disorders can involve serious medical risk, our intake team checks for medical stability before admission — including vitals, blood pressure changes when standing (orthostatic checks), and key lab work. If a higher level of medical care or inpatient weight restoration is needed first, we’ll refer you there and welcome you into our program once you’re medically stable.

Eating Disorder Treatment at Wavecrest Behavioral Health

At Wavecrest Behavioral Health, we treat eating disorders with the specialized team the illness requires — a CEDS clinician, a Registered Dietitian, a Nutritionist, and a psychiatric provider, all in-house — inside a program that can also address co-occurring substance use, anxiety, depression, and trauma without sending you to three different clinics.

If you, your teenager, or someone you love is struggling with food, weight, or body image, call Wavecrest today at (866) 366-6178. The conversation is confidential, and there’s no obligation.
