Plenty of people have skipped dinner before a night out, telling themselves they’re “saving room” for drinks. For some, that occasional choice hardens into a pattern: eat less so you can drink more, then drink to quiet the anxiety about eating. That pattern has a name now. It’s called drunkorexia, and it sits at the overlap of two serious conditions that tend to travel together: alcohol use disorder and eating disorders. Up to half of people with an eating disorder also use alcohol or other drugs, a rate roughly five times higher than the general population, according to the National Eating Disorders Association (NEDA). This page explains why the two so often co-occur, what drunkorexia is and why it’s dangerous, how alcohol interacts with anorexia, bulimia, and binge eating disorder, and what real treatment for both at once looks like. If you’re a parent worried about a college student, you’re in the right place too.
Alcohol use disorder and eating disorders co-occur so often partly because they come from overlapping causes. In a lot of people the two problems aren’t really separate at all. They pull from the same risk factors, lean on some of the same brain chemistry, and frequently end up doing the same job, which is managing pain that feels unmanageable any other way.
The overlap shows up in the numbers. NEDA reports that up to 50% of people with eating disorders use alcohol or illicit drugs, five times the rate of the general population. About one in five people with an eating disorder will develop a substance use disorder in their lifetime, a figure that traces back to a 2019 meta-analysis in Psychiatry Research. These aren’t two unlucky things happening to the same person by chance. They’re linked.
Several shared risk factors keep turning up across the research:
Then there’s the brain. Alcohol and the behaviors of an eating disorder, restricting, bingeing, purging, all act on the same dopamine-driven reward pathway, and each can produce a short, powerful sense of relief or control. That’s what clinicians mean by self-medication. Someone drinks to numb the anxiety that comes with eating, then restricts food to “make room” for the calories in the alcohol, and for a while it works well enough to keep doing. The relief is real. It just doesn’t last, and the deficit it leaves behind builds up quietly.
People often recognize that loop in themselves before they recognize a diagnosis. You drink to quiet the noise about your body, the drinking adds calories and shame, so you eat less, and eating less makes the next drink hit harder. It feeds itself.
Drunkorexia is the practice of restricting food calories to offset or intensify the effects of alcohol. In plain terms, a person eats less, skips meals, exercises hard, or purges so that drinking “fits” within a calorie budget, or so that alcohol hits faster on an emptier stomach. You’ll also hear it called alcorexia or alcohol anorexia.
One thing to be clear about: drunkorexia is a colloquial term, not a clinical diagnosis. It doesn’t appear in the DSM-5. A 2024 scoping review in the journal Nutrients describes it as a novel alcohol-related disorder that combines disordered eating, excessive exercise, and problem drinking, and the authors note the term still lacks a single agreed-upon definition. Researchers sometimes use the more technical label “food and alcohol disturbance” for the same cluster of behaviors.
The behaviors cluster into a handful of patterns. Some people restrict before drinking to “bank” calories for the alcohol. Some purge afterward, with vomiting, laxatives, or diuretics. Others over-exercise to “earn” or burn off what they drink, or skip food specifically so the alcohol hits faster on an empty stomach. Plenty of people do more than one of these, and they don’t always think of any of it as a problem.
The version clinicians tend to see is messier than the textbook one. It’s the student who eats a normal breakfast, talks herself out of lunch because there’s a formal that night, does an extra hour at the gym “to be safe,” and then has three glasses of wine on a stomach that’s basically empty. She’d tell you she’s being healthy. Nobody around her sees a problem, because every individual piece looks like something a careful, disciplined person would do. The calorie math is the only thread tying it together, and it usually stays private.
Drunkorexia can be hard to spot because each piece looks like something else, a diet here, a big night out there. The pattern is what gives it away. Watch for behavioral signs and physical signs together.
Behavioral signs:
Physical signs:
That last one matters more than it seems. A 2023 study of more than 2,300 college students in the journal Eating Behaviors found that drunkorexia behaviors were strongly tied to blacking out, with about 61% of participants reporting drunkorexia and 40% reporting a blackout in the past year. If a friend never eats on party days and routinely can’t remember the night, those two facts belong in the same sentence.
The core danger is simple physiology. Drinking on an empty stomach speeds how fast alcohol gets into your blood. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) explains that with little food in the stomach, alcohol passes into the small intestine and bloodstream more quickly, producing a higher blood alcohol concentration than the same drinks would on a full stomach. Picture the same three drinks: fed, the rise is gradual; fasted, it spikes. That spike is the difference between feeling loose and losing motor control, and it’s the window where blackouts and alcohol poisoning happen.
Malnutrition stacks on top. Alcohol delivers calories with almost no nutrients, and chronic drinking impairs how the body absorbs the nutrients it does take in. When someone is also restricting food, the body is short on fuel and short on the nutrients it needs to repair itself. Over time, organ damage tends to be worse in a malnourished body, and the brain is more exposed to lasting harm.
Dehydration is the third multiplier. Alcohol is a diuretic, so it pulls water out. Pair that with a restricted intake of food and fluids and you get someone who is intoxicated, depleted, and at higher risk of a medical emergency than they look.
Drunkorexia clusters where heavy drinking and body-image pressure collide, and few places concentrate both like a college campus. Researchers have studied it most in college women, but it affects students of all genders, and some studies have found the behaviors just as common among young men.
The prevalence numbers are striking. One often-cited study found that 34% of college students engaged in drunkorexia behaviors, rising to 81% among students who drank heavily. A separate University of Houston study of 1,184 heavy-drinking students found that more than 80% had engaged in at least one drunkorexic behavior in the prior three months. Drinking itself is widespread in this age group: the 2024 National Survey on Drug Use and Health found that about 47% of young adults ages 18 to 25 drank in the past month. When drinking is that normalized, the disordered habits riding alongside it can blend in.
The drivers are familiar to anyone who works with this age group: body-image pressure, party culture, the cost of both food and alcohol on a student budget, and the stress of a new, competitive environment. A common campus scenario is pre-gaming on an empty stomach, saving money and calories at once, then drinking fast on nothing. Parents and RAs are often the ones positioned to notice it, if they know what they’re looking at. The hard part is that for a long stretch it just looks like ordinary college life.

Find Treatment Near YouAnorexia and alcohol use disorder reinforce each other through restriction. Both revolve around control, and alcohol can become a tool for keeping that control while numbing the distress that comes with it. For someone with anorexia, a drink can do several jobs at once: quiet anxiety, suppress appetite, and provide calories that feel “allowable” because they aren’t food.
That logic is what makes the combination so dangerous. Alcohol is essentially empty calories, so a person can drink instead of eating and feel they’ve held the line on food. The body, meanwhile, is getting neither nutrition nor rest. The day-restriction, night-drinking pattern, eating little or nothing during the day so the calorie “budget” goes to alcohol at night, is a common one, often without the person realizing it’s a recognized pattern at all.
The stakes here are higher than with most psychiatric conditions. Anorexia nervosa has one of the highest mortality rates of any psychiatric disorder, a finding established in a landmark 2011 meta-analysis and confirmed repeatedly since. Add heavy alcohol use to a body already weakened by starvation and the risk multiplies. Co-occurring anorexia and alcohol use disorder is less common than the bulimia overlap, but when it happens, it’s especially serious.
It’s also why “why do alcoholics not eat” is such a common search. The short version: heavy alcohol use suppresses appetite, irritates the stomach, and displaces meals with empty calories. We answer that question in full in the FAQ below.
With bulimia, alcohol usually attaches to the shame. The cycle runs binge, then purge to undo it, then a flood of guilt and self-criticism, and drinking becomes the thing that quiets the guilt. The catch is that the drinking also lowers inhibition, which sets up the next binge. Because the whole thing runs on emotion rather than reasoning, telling someone to just use more willpower tends to miss the point entirely.
This is the strongest overlap in the research. The clinical literature finds that up to 41% of people with bulimia nervosa have a co-occurring alcohol use disorder, roughly four times the rate seen with anorexia. The shared traits, impulsivity and difficulty regulating emotion, help explain why bulimia and problem drinking line up so often.
The physical risks are serious. Purging after heavy drinking compounds dehydration and electrolyte loss, and drinking on a purged, empty stomach raises the alcohol-poisoning risk described earlier. Bulimia also carries a well-documented link to depression and elevated suicide risk, and alcohol, a depressant, can deepen both. That combination deserves careful, compassionate attention rather than alarm, and it deserves professional help.
Binge eating disorder (BED) and alcohol misuse are connected through disinhibition and a shared reward pathway. BED is the most common eating disorder in the United States, with a past-year prevalence of about 1.2% among adults and roughly double that over a lifetime, according to the National Institute of Mental Health (NIMH). It affects about twice as many women as men.
The link with alcohol works in a couple of ways. Both bingeing and drinking light up the same dopamine reward circuit, so the brain learns that either one will do the job. Alcohol also lowers inhibition and can nudge appetite and hunger signaling upward, so a binge becomes a lot more likely once the drinking starts. For many people the two simply happen on the same nights, and each makes the other harder to stop.
If BED is the main concern, it deserves its own deeper look, including the full range of treatment options. The focus here is the alcohol link specifically: drinking tends to make binge episodes more frequent and harder to interrupt, and treating the drinking often makes the eating easier to address.
The most effective approach to co-occurring alcohol use and eating disorders is integrated, dual-diagnosis treatment, which addresses both conditions at the same time, with one coordinated team. The Substance Abuse and Mental Health Services Administration (SAMHSA) identifies integrated treatment as a best practice for co-occurring disorders, noting that treating mental health and substance use together leads to better outcomes than treating them in separate silos.
In practice, that usually means a combination of evidence-based therapies, cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) are common, paired with nutrition counseling and medical support. What that plan actually looks like depends on the person. How severe each condition is, whether they’re medically stable, what past treatment they’ve had, what other mental health conditions are in the mix, and what kind of support waits for them at home all change the picture. Two people with the same two diagnoses can need very different things.
The sections below walk through the pieces in the order they typically happen.
Treating one disorder while ignoring the other is the most common way recovery stalls. The reason is mechanical: the two conditions share triggers and coping functions. If you treat the drinking but leave the eating disorder untouched, the anxiety and distress the eating disorder generates are still there, and alcohol is still the learned way to manage them. The untreated condition becomes the on-ramp back to the treated one.
A concrete version: someone completes alcohol treatment, goes home, and hits the same body-image anxiety that always drove their drinking. Nothing has addressed that anxiety. Drinking resumes, not from weakness, but because the underlying problem was never part of the plan. That’s why integrated care treats both as primary, rather than ranking one above the other.
For alcohol, detox should happen under medical supervision, because alcohol withdrawal can be genuinely dangerous, and in some cases life-threatening. That’s true for anyone. For someone with a co-occurring eating disorder, the risk is higher still, because a body that’s malnourished and electrolyte-depleted has less margin for the stress of withdrawal.
There’s a specific clinical concern worth flagging: refeeding syndrome. When someone who has been severely undernourished begins eating again, dangerous shifts in fluids and electrolytes can follow if it isn’t managed carefully. Both chronic alcohol use and eating disorders raise the risk of refeeding syndrome, which is one more reason this stage belongs in medical hands, not a do-it-yourself plan.
The plain-language difference: in inpatient (residential) treatment, you live at the facility; in outpatient treatment, you live at home and come in for sessions. Both can deliver the core ingredients, therapy plus nutrition counseling, but they suit different situations.
A few factors usually point toward inpatient care: medical instability, severe malnutrition, a high-risk drinking pattern, co-occurring conditions that need close monitoring, or a history of outpatient attempts that didn’t hold. Outpatient care can work well when someone is medically stable, has a supportive home environment, and can keep up with treatment while living their life. The honest answer to “which one do I need” comes from an assessment with a clinician, not a quiz.

Heavy alcohol use suppresses appetite in several ways at once. Alcohol provides calories with almost no nutrients, creating a false sense of fullness, and it irritates the stomach lining, which can cause nausea and food aversion. It also disrupts hunger hormones like ghrelin and slows digestion. Over time, drinking displaces meals, and the body absorbs fewer nutrients from what little food does get eaten.
Drunkorexia describes a real and well-documented pattern of behavior, but it isn’t a formal diagnosis. It doesn’t appear in the DSM-5, and researchers note it still lacks a single agreed-upon definition. Clinicians sometimes call it “food and alcohol disturbance.” Real or not as a diagnostic label, the behaviors it describes carry serious medical risk.
Drinking doesn’t directly “cause” an eating disorder, but the two share risk factors and reinforce each other. Alcohol can deepen body-image anxiety, lower the inhibition that keeps bingeing in check, and become a tool for restriction or numbing. In someone already vulnerable, heavy drinking can help disordered eating take hold or get worse.
Yes. With little food in the stomach, alcohol moves into the small intestine and bloodstream more quickly, producing a higher blood alcohol concentration than the same amount of alcohol would on a full stomach, according to NIAAA. That faster rise raises the risk of blackouts and alcohol poisoning.
Yes, and that’s the recommended approach. Integrated, dual-diagnosis treatment addresses both conditions together with one coordinated team. SAMHSA identifies this as a best practice, because treating both at once produces better outcomes than handling them separately, where the untreated condition tends to undo progress on the other.
