Eating Disorder Relapse: Warning Signs and What to Do

Eating disorder relapse prevention is a crucial part of treatment. Eating disorders are often hard on, and can even be traumatic for, the person experiencing it and the people around them. They also develop for a reason: people must explore the role(s) the eating disorder plays or played in their life (e.g., coping, a sense of safety or certainty) so they can meet these needs in a healthier way and reduce vulnerability.

That said, relapses happen. They’re very common. They aren’t the end. They don’t mean that recovery is hopeless or that a person stopped trying. When you notice the signs of an eating disorder relapse, the next step is to seek help.

If you’ve heard the phrase “recovery isn’t linear” before, this is exactly what it means. There are hard times and more carefree ones. A flexible approach that lets you seek extra support before relapse happens, or as soon as you notice it, matters.

Knowing the warning signs of an eating disorder relapse can be important both for the person with the condition and those around them. Let’s talk about eating disorder relapse, including common warning signs and what to do about them, whether you are a person with an eating disorder or their loved one.

How Common Is Eating Disorder Relapse?

How common is relapse in eating disorders? Approximately one-third to one-half of people relapse following initial recovery.[1] Statistics vary by disorder. Across many studies, anorexia has the highest relapse risk. BED has the lowest. Factors like early discharge, illness duration, social support, length of remission, and the variety of foods a person eats can also play a role.

High relapse rates reflect the chronic nature of the illness. They are not a matter of personal weakness or not trying hard enough. It does not mean that treatment didn’t work. Relapses indicate the need to return to a higher level of care and are often part of recovery.

Lapse vs. Relapse - What's the Difference?

What does relapse mean in ED recovery? How does it differ from a “lapse?” Why does it matter?

Lapse. A lapse is a temporary return to a behavior. It’s another term for a slip-up. A lapse could be one skipped meal, one purging episode, one day of restriction, or one binge.
Relapse. A relapse is when these things become a pattern. It’s a sustained return to eating disorder behaviors.

What happens next, even in the 48 hours after a lapse, largely determines whether it becomes a relapse. A lapse is not a failure. Ideally, lapses provide information you can use to protect your recovery moving forward. It’s an opportunity for reflection. Talk to your therapist or dietician about what happened leading up to it and what you can do to reduce vulnerability now.

Treating a lapse as a full-blown relapse can become a self-fulfilling prophecy. Letting behaviors continue is also a problem. The ideal balance is recognizing the lapse without letting it spiral. Lapses happen to everyone in eating disorder recovery. What matters is how you navigate it.

Early Warning Signs of Eating Disorder Relapse

Learning to detect the early warning signs of a relapse is crucial. When you identify it sooner, you can address it before behaviors become more ingrained, and the eating disorder takes a greater toll. People might notice behavioral, cognitive, emotional, and physical warning signs of an eating disorder relapse in themselves or someone else.

Behavioral warning signs

You might notice that you or your loved one isolates more or says “no” to a growing number of foods. Sometimes, it’s hard to distinguish the “why” behind these things. Behavioral signs look different for everyone. Other common ones include:

Returning to food rigidity or rule-making
Eating alone or avoiding social meals
Secretiveness around food, exercise, or body
Compensatory behaviors resuming (purging, excessive exercise, restriction)
Checking behaviors increasing: weighing, measuring, mirror checking
New-to-you eating disorder behaviors start (e.g., a shift from previous anorexia to orthorexia)
Making small negotiations with the illness

Eating disorders are sneaky. Let’s say you used to get a favorite beverage at a coffee shop whenever you went with friends. You make a small negotiation, perhaps without fully realizing it, with the illness and now only drink “the safest” or a specific, low-calorie option.

This differs from choosing or trying a new drink for another reason. This is an instance where the person with the condition needs to get good at detecting why they’re doing something.

Cognitive and emotional warning signs

Eating disorders affect the way you think and feel. Individuals with eating disorders often have co-occurring mental health concerns that require treatment, support, and self-care. People and families or loved ones can also look out for cognitive and emotional warning signs of eating disorder relapse:

Intrusive food or body thoughts increasing in frequency
Looking back at the eating disorder with nostalgia (e.g., “I was more in control then”)
Worsening depression, anxiety, or shame
Perfectionism and rigidity creeping back into non-food areas of life
Disengaging from therapy, dietitian, or support network

One thing you will learn when you or your loved one has an eating disorder is how gradual these things can be. Noticing them–and telling a professional who understands the severity of eating disorders and the roles they can play in a person’s life–matters.

Physical warning signs

Sometimes, behaviors and cognitive or emotional signs go overlooked, especially for those who have not had extensive help (or practice) with relapse prevention. Sometimes, you’ll notice physical warning signs first.

Unexplained weight changes
GI symptoms returning
Sleep disruption
Fatigue, dizziness, or cold intolerance re-emerging

When you notice these, reflect on any behavioral, emotional, social, or cognitive changes that are also present. This can help you better understand your other personal relapse warning signs.

Common Eating Disorder Relapse Triggers

Even positive life changes could increase relapse vulnerability. You can’t prevent life from happening, and the goal is NOT to avoid the ups, downs, and transitions life brings. Understanding common relapse triggers, such as those listed below, helps you remember to take extra care of yourself during these times.

Stressful life events. Stressful life events, such as job loss, relationship breakdown, and bereavement, have known effects on eating disorder relapse probability.[2]
Major transitions. Starting college, moving, or having a child can bring uncertainty, changes in routine, and possibly new triggers.
Diet culture exposure. Many people experience seasonal triggers (e.g., the New Year or Summer, when diet culture is rampant). It could also be social media or exposure to family and peer comments on bodies (anyone’s body – not just theirs)!
Anniversary reactions. For example, dates associated with illness onset or past trauma.
Discontinuing medication or therapy prematurely.
Physical illness or injury, especially if it disrupts movement routines, body image, or food restrictions.
Co-occurring mental health flare. When symptoms of depression, anxiety, or PTSD get worse, the eating disorder sees an “in.”

It can help to familiarize yourself with the concept of emotional relapse. Often, this term is used in the context of substance use disorders. It can apply to eating disorders, too. During an emotional relapse, you don’t actually use behaviors: it’s an emotional state that increases relapse vulnerability. Pay extra attention to your routines, make sure you have support, and get help if you notice possible relapse warning signs.

What to Do If You Think You're Relapsing

What should you do if you think you’re relapsing? Don’t keep it a secret. Follow these steps instead.

Step 1: Name it without catastrophizing. Acknowledging a lapse early is protective. It can actually be a great sign of progress.
Step 2: Contact your treatment team before it escalates – not after. Don’t wait.
Step 3: Use your relapse prevention plan. If you don’t have one, ask your therapist to help you build one now.
Step 4: Return to structure. This often includes mechanical eating, regular check-ins with your therapist or dietician (more frequent appointments), and removing environmental triggers.
Step 5: Step up in care if needed. Returning to IOP or PHP means you will have optimal support as you get back on track.

If medical symptoms are present (e.g., fainting, chest pain, extreme weakness), go to the emergency room right away. Physical stabilization must happen first.

What to Do If Someone You Love Is Relapsing

Panic and anger are not the antidote here. Don’t panic or overreact. A calm, concerned response is more effective than alarm. Bring it up once: state your concern clearly and with care. Use “I” statements.

For example: “I notice you have not been eating meals with us and say that you feel tired a lot. I’m worried about your eating disorder and was wondering if I could help you increase your appointments or ask about going back to IOP. I can make phone calls and drive you if you need.”

Do not monitor or police the person’s behavior. If you are worried about safety, contact their treatment team directly. It can be hard to know how to help someone with an eating disorder. Treatment professionals can help guide you through it.

How to Reduce Your Risk of Relapse

Eating disorder relapse prevention usually involves a combination of self-awareness, protective factors, and knowing who to talk to when a lapse happens. Use this checklist to set yourself up for success.

Maintain aftercare. Therapy and dietitian check-ins should persist past the point of feeling “fine.”
Identify your personal high-risk triggers.
Build and review a written relapse prevention plan with your treatment team.
Protect the environmental basics (e.g., sleep, routine, social connection).
Stay connected to peer support. Remember that resources like the NEDA helpline, recovery communities, and support groups are there.
Have a named contact to call before a lapse becomes a relapse. Even if you don’t, for example, see a dietician as much as you used to, keep their email or phone number so that you can book an appointment or get advice after using an eating disorder behavior.

Frequently Asked Questions

How common is relapse in eating disorders?

Eating disorder relapse is very common. While statistics vary, relapse rates generally sit at around one-third to one-half of people with eating disorders. This does not mean that the person won’t reach long-term remission. It’s a common part of recovery and simply indicates the need to seek more support again.

What is the difference between a lapse and a relapse?

The difference between a lapse vs. relapse in eating disorder recovery is that a lapse is a single slip-up. A relapse is a reemerging pattern of eating disorder behaviors.

What are the first signs of eating disorder relapse?

Emotional, cognitive, and behavioral signs of an eating disorder relapse often happen first. Look out for things like changes in recovery routines (e.g., eating regular meals and snacks), social isolation, worsened mental health, or “missing” the eating disorder.

What should I do if I feel myself relapsing?

Contact a member of your care team or support system if you feel yourself relapsing or experience a lapse. They can provide accountability and guidance. It’s better to increase support as a protective factor than it is to wait, even if you think it is “not that bad.”
