Anorexia nervosa is a serious mental illness, not a diet taken too far, a phase, or a bid for attention. It takes hold of how a person thinks about food, weight, and their body, and it can be exhausting, isolating, and frightening to live with. It is also treatable, and people do recover fully, even when that feels impossible from the inside.
Anorexia nervosa is one of the Eating Disorders we treat, distinct from Bulimia Nervosa and Binge-Eating Disorder though it can share some of the same roots. At its core is a powerful drive to limit eating, alongside an intense fear of gaining weight and a view of one’s own body that does not match what others see. For many people it becomes a way to feel in control when everything else feels uncertain.
Anorexia does not come from any single source. It usually grows out of several factors overlapping:
Biology and temperament — a genetic vulnerability, often with traits like perfectionism, anxiety, or a need for control
Co-occurring conditions such as Depression, an Anxiety Disorder, or Obsessive-Compulsive Disorder (OCD), which frequently travel alongside it
Difficult experiences — trauma, loss, bullying, or major upheaval that leaves a person searching for something to manage
Cultural pressure — a steady stream of messages tying thinness to worth, success, or safety
A self-reinforcing cycle, as the effects of prolonged undereating deepen the thinking that drives it
None of this is a person’s fault, or the product of vanity or poor parenting. Understanding the mix behind it simply helps treatment reach the roots, not just the symptoms.
Anorexia shows up in behavior, mood, and the body. Signs to watch for include:
Eating less over time, skipping meals, or following increasingly rigid food rules and rituals
Preoccupation with food, weight, and appearance that crowds out other thoughts
Avoiding meals with others, or becoming anxious and distressed around eating
A harsh, distorted body image that no amount of reassurance can budge
Physical effects of undernourishment, such as feeling cold all the time, exhaustion, dizziness, or changes to hair and skin
Pulling away from friends, activities, and the parts of life that used to bring joy
If some of this feels familiar, in yourself or someone you care about, our Online Assessment is a confidential way to take a closer look.
A first conversation is calm, respectful, and free of judgment. It is a chance to understand what is happening and what kind of support will help most, and it looks at:
the thoughts, fears, and patterns, and how long they have been present
anxiety, low mood, trauma, or other conditions woven through it
a careful, coordinated look at how your body is doing, since that shapes what treatment needs to happen first
Where medical needs are pressing, we help make sure those are handled alongside the emotional work. Our Admissions Process page walks through how to start, and an initial appointment can be done by secure video if that feels more manageable.
Anorexia responds best to a coordinated approach: psychological therapy at the center, working with medical monitoring and nutritional support. The main approaches we use:
The most established therapy for eating disorders is an enhanced form of CBT built specifically for them, often called CBT-E. It targets the rigid rules and fearful thinking around food and weight, and helps you test and loosen them one step at a time, so eating can gradually become less charged.
Anorexia is bewildering and painful for the people closest to you, who often want to help but end up guessing. In family work, they learn what the illness is really doing, how to talk about food and weight without fueling the fear, and how to steady rather than pressure.
When restriction is bound up with emotions that feel unbearable, DBT teaches concrete ways to manage that distress without leaning on the eating disorder. You practice sitting with hard feelings, steadying your reactions, and weakening the pull toward old patterns over time.
Anorexia often serves a purpose — a sense of control, safety, or identity — that runs deeper than food. This work explores those underlying roots, so the illness loses its hold as the needs beneath it are understood and met in healthier ways.
Medical and nutritional care are part of the picture too, and short-term medication sometimes helps with co-occurring anxiety or depression. Our Therapy Options page lays out everything we provide.
The right level of care depends on how severe the anorexia is and what your body needs. Support ranges from weekly sessions to full-time care, and can change as recovery progresses. Starting with the lightest touch and building up:
For anorexia that has become severe or medically fragile, a residential stay offers full-time, structured support in one place. It surrounds you with care during the hardest stretch, when eating and safety need close, steady attention.
A good match when you need real support but can safely spend time at home. Several structured sessions a week keep recovery moving, steadying eating, building skills, and staying connected to your own life.
For anyone in Missouri, the same care is available entirely through secure video, so distance or a hard commute never has to be the reason you go without support.
Recovery keeps going long after the intensive phase ends. Regular check-ins and a connected alumni network give you somewhere to turn when old thoughts try to creep back.
When anorexia has meant time in the hospital, this step gives you a structured, supportive place to keep rebuilding strength and steadiness before daily life resumes.

The right place for anorexia treatment matters. Here is what you can expect from us:
Anorexia affects the body and the mind at once, so treating only one side rarely works. We handle the psychological treatment and coordinate the medical and nutritional side, so the parts of your recovery actually talk to each other. You are not left stitching separate providers together yourself.
Eating disorders are their own field, and general talk therapy often is not enough. Our clinicians work with anorexia specifically and understand how it thinks, hides, and resists, so you are met by people who know what you are up against. That means less time explaining and more time getting somewhere.
Shame keeps anorexia going, so we work hard not to add to it. Conversations here are direct but never judgmental, with no lecturing and no moralizing about food or your body. You can be honest about what is happening without bracing for a reaction.
Recovery should not mean putting the rest of your life on hold. We offer flexible scheduling and secure video sessions across Missouri, so treatment can fit around work, school, or family. For many people, keeping some normal footing makes it easier to stay in treatment.
Recovery is far easier with people in your corner who understand what is going on. We make space for partners, family, or close friends to take part, so support at home works with your treatment instead of pulling against it. No one should have to do this alone.
People come to us from all over the St. Louis area — Maryland Heights, Bridgeton, Hazelwood, and Overland among them — along with the surrounding communities. And because anorexia reaches people far beyond any one clinic, we provide the same treatment over secure video across the rest of Missouri, including Nevada, Aurora, and Lamar.
The clinicians you would work with are on our Meet the Team page. And if you are trying to understand what recovery actually looks like, our Patient Guides walk through it in plain terms.
Reaching out is hard, especially when part of you is not sure you want to let the anorexia go. That ambivalence is normal, and it does not have to be resolved before you begin. Most people who get real treatment recover, and the sooner it starts, the better the odds.
We keep the logistics simple. Our team sorts out Insurance Verification ahead of time, so cost is not a barrier between you and help.
St. Louis Mental Health is here when you are ready — call (314) 237-4435 or use our Contact Us page. Whatever your relationship with food looks like right now, it can get better, and you will not be doing it alone.
Do I have to be a certain weight to have anorexia or to get help?
No. Anorexia is defined by your relationship with food, weight, and your body, not by any single number or how you look to others. People of many different body sizes struggle with it, and you never have to prove you are sick enough to deserve care. If you are not sure where you stand, our Online Assessment is a private place to start.
Is anorexia really a mental illness, or just about food?
It is very much a mental illness. The food and weight behaviors are the visible part, but underneath are real difficulties with anxiety, control, self-worth, and emotion. That is why treatment goes well beyond eating and addresses what is driving it, and why willpower alone is never the answer.
Do you provide medical and nutritional care too?
We provide the psychological treatment at the heart of recovery and work alongside medical and nutritional specialists, so every part of your care pulls in the same direction. If someone is medically unstable, a hospital or specialized medical setting may be needed first, and we help make sure the right care happens in the right order.
Will insurance cover treatment for anorexia?
Usually, yes. Anorexia is a recognized mental health condition, and treatment is generally covered like other behavioral health care, though the details depend on your plan and the level of care involved. We will look into all of that for you through our Insurance Verification page before treatment starts.
Can people really recover from anorexia?
Yes. Recovery can be hard and is rarely a straight line, but people reach a place where food is no longer the center of their lives and the fear loses its grip. Many go on to feel more like themselves than they have in years. Our Treatment Outcomes page offers a grounded look at what getting better tends to involve.
