Eating disorders don’t simply go away on their own, but the majority of people do recover over time, especially with treatment. In a 22-year follow-up study, about 63% of people with anorexia nervosa and 68% of people with bulimia nervosa had fully recovered. The path to that point, however, is rarely quick or linear. Recovery typically takes years, and the timeline varies significantly depending on the type of eating disorder and when treatment begins.
Recovery Rates by Type
How likely recovery is, and how long it takes, depends heavily on which eating disorder someone has.
Bulimia nervosa has the fastest median recovery time: about 3.8 years. Most recovery happens within the first 4 to 9 years, and rates don’t increase much beyond that window. By the 22-year mark, roughly 68% of people originally diagnosed with bulimia have fully recovered.
Anorexia nervosa follows a slower, steadier trajectory. In the first few years, only about a third of people recover. That number climbs to 47% between 4 and 10 years, and reaches roughly 73% in studies that follow people for more than a decade. The key takeaway is that recovery from anorexia keeps happening over the long term. People who haven’t recovered at the 5-year mark aren’t out of options.
Binge eating disorder tends to have favorable outcomes even without formal treatment. In one 5-year study of young women, 50% of those with binge eating disorder had fully remitted, compared to 35% of those with bulimia. That said, “favorable” doesn’t mean the disorder is harmless or that treatment isn’t worthwhile. It means the condition is less likely to become entrenched over many years.
Why “Going Away” Is the Wrong Frame
Thinking of an eating disorder like the flu, something your body fights off and then it’s gone, doesn’t match how these conditions actually work. Eating disorders involve deeply learned patterns of thought and behavior around food, weight, and control. Recovery means those patterns weaken and lose their grip, not that they were never there.
Researchers who study what recovery actually looks like have identified several consistent markers. People who consider themselves recovered describe returning to a normal eating pattern, no longer being obsessed with food or weight, and developing a more relaxed relationship with their body. Beyond the food-specific changes, they report broader psychological shifts: greater self-acceptance, stronger relationships, a sense of personal growth, and more resilience when life gets stressful. In other words, recovery isn’t just the absence of disordered behaviors. It’s the presence of a fundamentally different way of relating to yourself.
The Brain Does Heal
One encouraging finding is that the physical brain changes caused by eating disorders are largely reversible. Anorexia nervosa, in particular, can cause measurable thinning of the brain’s outer layer, especially in areas involved in decision-making and emotional regulation. But brain imaging studies comparing people currently ill, people who have weight-recovered, and healthy controls show that nearly all of these structural differences resolve once weight is restored and maintained. The threshold that seems to matter most is sustaining a BMI above about 19.5.
This matters because one of the most discouraging aspects of an active eating disorder is the feeling that your brain is working against you. It often is, literally. Malnutrition changes how the brain processes reward, risk, and emotion. But those changes are not permanent. Nutritional rehabilitation allows the brain to rebuild, which in turn makes the psychological work of recovery more effective.
Early Treatment Makes a Difference
Evidence suggests that receiving treatment within the first 3 years of an eating disorder significantly improves the chances of full recovery. This is one of the clearest and most actionable findings in eating disorder research. The longer disordered eating patterns persist, the more entrenched they become, both psychologically and neurologically. Early intervention disrupts that process before the disorder has time to become a person’s default way of coping.
This doesn’t mean that someone who has been struggling for a decade should give up. The long-term data on anorexia is clear: recovery continues well past the 10-year mark. But it does mean that if you or someone you know is in the early stages, the window for the most efficient recovery is now.
The Stakes of Not Recovering
Eating disorders carry real medical risk. A large meta-analysis covering data through 2024 found that people with eating disorders have a mortality rate about 3.4 times higher than the general population. Anorexia nervosa carries the highest risk, with a mortality rate roughly 5 times the expected baseline. Bulimia nervosa doubles the risk, and even binge eating disorder carries a modest elevation.
These numbers reflect the full spectrum of medical complications, from heart problems caused by malnutrition and purging to the psychological toll that can lead to suicide. They also underscore why the question “do eating disorders go away” matters so much. For most people, the answer is yes, with time and support. But waiting passively for the disorder to resolve on its own is a gamble with serious consequences.
What Recovery Actually Takes
Recovery from an eating disorder is measured in years, not weeks. It typically involves some combination of therapy, nutritional support, and in more severe cases, structured treatment programs. The specific approach matters less than the consistency. People recover through many different paths, but almost all of them require sustained effort over a long period.
One of the most important things to understand is that setbacks are a normal part of the process, not evidence that recovery is impossible. The long-term studies that show 60 to 70% recovery rates are tracking people through relapses, difficult periods, and incomplete attempts. The trajectory bends toward recovery, but it bends slowly. Patience with yourself, or with someone you care about, is not optional. It’s part of what makes recovery work.
