Eating Disorders, Substance Abuse, and Substance Abuse Disorders

Eating disorders commonly co-occur with substance abuse and substance use disorders (SUD), which are behavioral health conditions that develop when addiction is present. Individuals with eating disorders most typically abuse alcohol, laxatives, emetics, diuretics, amphetamines, heroin, and cocaine. Although researchers are still exploring the relationship between eating disorders and substance abuse, the prevalence of co-occurrence is evident as exemplified in the statistics below.

According to the National Eating Disorders Association (NEDA) , up to 50% of individuals with eating disorders use alcohol or drugs, which is five times more than the general population.
Also according to NEDA , up to 35% of individuals dependent on substances also have eating disorders, which is 11 times more than the general population.
The Substance Abuse and Mental Health Services Administration (SAMHSA) , reports that 27% of individuals with anorexia have an SUD. SAMHSA also shares that 36% of individuals with bulimia have an SUD and that 23% of individuals with binge eating disorder (BED) have an SUD.

THE RELATIONSHIP BETWEEN EATING DISORDERS AND SUBSTANCE ABUSE

Both eating disorders and substance use disorders are extremely complex. When the two kinds of disorders co-occur, they become even more complicated, and researchers are still working to understand the associations between them.

Some individuals develop an SUD before an eating disorder, while others develop an eating disorder before an SUD. Furthermore, some theories identify disordered eating behaviors, such as binging and purging, as types of addiction in themselves. Eating disorders and SUD do share some of the same risk factors and characteristics which may help explain the high prevalence of co-occurrence.

Shared Risk Factors and Characteristics

Family history: Many individuals with eating disorders have a family member who also experienced one. The same goes for substance use disorders. Because stigma surrounds both illnesses, many families veil them in secrecy. As a result, individuals are frequently unaware that they have a loved one who has struggled with an eating disorder or substance abuse.
A history of trauma, abuse, or neglect: Painful experiences involving trauma, abuse, or neglect increase the risk of developing both eating disorders and substance use disorders. Both drug abuse and disordered eating behaviors can be attempts by individuals to cope with emotional pain caused by trauma, abuse, or neglect.
Brain chemistry: Eating disorders and substance use disorders are illnesses that affect the brain. Additionally, the behaviors associated with both illnesses can become ingrained within the brain.
Low self-esteem : Many individuals who struggle with substance abuse and/or eating disorders also struggle with low self-esteem, which can lead to feelings of worthlessness and drive unhealthy behaviors.
Lack of family and social connection: Commonly, individuals who develop substance abuse or eating disorders lack a healthy connection with their families. Additionally, individuals who struggle with substance abuse and/or eating disorders tend to withdraw from normal social interactions. To mitigate feelings of loneliness and increase feelings of support, most treatment programs for eating disorders and substance abuse emphasize the power of establishing healthy relationships with one’s family, friends, and community.
Impulsive personality types: Many individuals who struggle with substance abuse and/or eating disorders possess personalities that are prone to impulsivity and extremes, two characteristics of many behaviors associated with substance abuse and eating disorders.
Compulsive behavior: Both substance abuse and eating disorders involve destructive behaviors that effectively overtake one’s life and interfere with their ability to carry out daily activities.
Social pressures: Both substance abuse and eating disorders tend to spread within social circles, and one’s peers can influence whether they begin to engage in behaviors associated with substance abuse and eating disorders.

THE DANGERS OF DRUNKOREXIA

At the intersection of eating disorders and substance abuse, drunkorexia is a colloquial term that describes the combination of disordered eating and binge drinking, seen most often in young adults. Individuals who engage in drunkorexia behaviors may restrict their food intake, use diuretics, purge their food, or exercise excessively in order to offset the calories taken in while drinking alcohol and/or increase the feeling of intoxication. When combined, these behaviors of food restriction and drinking can cause medical consequences including dangerous blood-alcohol levels, severe dehydration, vitamin depletion, and organ dysfunction.

TREATMENT FOR EATING DISORDERS AND SUBSTANCE ABUSE

The stigma and secrecy that surrounds substance abuse and eating disorders alike can make it scary for individuals who are struggling with either or both to seek support. A simple conversation with a mental health professional, however, can put you on a path towards healing. At Thrive, we provide both outpatient and inpatient treatment that targets your mental, behavioral, and physical health.

Is It OCD or an Eating Disorder? What Parents Need to Know

July 17, 2025

As a parent, noticing alarming behaviors around food or routines in your child can raise some important questions. You might be asking yourself, “Is this an eating disorder, obsessive-compulsive disorder (OCD), or something else entirely?” Understanding the signs and differences between these disorders is key to getting your child effective, timely treatment. In this blog, we’ll break down the overlap between OCD and eating disorders, what signs to watch for, and how to get professional help. If you're a parent wondering “Is my child’s eating disorder actually OCD?” or “OCD vs eating disorder in teens,” know that you’re not alone and you’re in the right place to find specialized care for your child. What Is OCD? Obsessive-Compulsive Disorder (OCD) is a mental health condition where unwanted thoughts (obsessions) cause anxiety, leading to repetitive behaviors (compulsions) intended to ease that anxiety. OCD can be focused on any subject. Common obsessions include contamination, perfectionism, scrupulosity, and harm, but sometimes, the content of obsessions can be focused on food, body image, or weight. What Is an Eating Disorder? Eating disorders , like anorexia nervosa, bulimia nervosa, binge eating disorder, and avoidant/restrictive food intake disorder (ARFID) involve disturbed eating behaviors and intense concerns about body weight or shape. These conditions go beyond dieting or “picky eating” and can become life-threatening without professional intervention. The Overlap: Why It Can Be Confusing OCD and eating disorders often share similar symptoms : Ritualistic eating (e.g., needing to eat foods in a certain order or at a certain time) Rigid rules about food (like only eating certain food groups or certain amounts of food) Excessive checking (like weighing food or body or repeated checking of expiration dates or thorough cooking) Avoidance behaviors ( like avoiding carbs, fats, or other food groups or avoiding places or objects that can trigger obsessions) Distress when routines are disrupted (either around mealtimes or exercise routines) So, How Can You Tell the Difference? Use the following chart to compare and contrast symptoms of OCD and eating disorders.

Navigating Coming Out: Emotional Wellness Tips for Every Stage

June 4, 2025

Coming out is a deeply personal, courageous, and in many cases, life-changing act. Whether you're sharing your sexual orientation or gender identity, coming out is about embracing authenticity and sharing an essential part of who you are. During the process of coming out, prioritizing your mental health at every stage is crucial. In this blog, we'll discuss insights and strategies to support your mental health before, during, and after coming out. Wherever you are in your journey, know that your experience is valid and you are not alone. Understanding the Mental Impact of Coming Out Coming out can bring about a lot of big feelings, including fear, relief, joy, anxiety, grief, and hope, sometimes all at once. Know that heightened emotions during this time are completely normal. Sharing such an integral part of yourself with the world can feel intense, but even with the ups and downs, being authentically you is worth it. Because LGBTQIA+ individuals face added mental health burdens due to stigma and discrimination, taking care of yourself during this time is more important than ever. You might experience increased anxiety, mental exhaustion, or avoidance ahead of coming out, so don’t be afraid to reach out for support. At its core, coming out is about authentic self-expression and showing your truest self, which can feel both exciting and scary at the same time . The self-acceptance and community gained from coming out is a vital part of finding long-term strength and joy. Still, it’s okay if you feel uncertain or conflicted, and these feelings are just part of the process. Before Coming Out: Emotional Preparation Coming out starts with reflection. Remember that there’s no rush when it comes to figuring out who you are. It’s okay to take time to understand your identity and what coming out might mean for you. Here are a few questions to consider: What do I hope to gain by coming out? Who feels emotionally safe to talk to? What are my fears, and how can I manage them? Mental wellness tips before coming out: Journaling can help you better understand your feelings and fears and explore different ways to share your truth. Talking through your feelings and different scenarios with a therapist , especially one who is LGBTQIA+ affirming, can help you to feel more supported and ready to come out. Practice grounding techniques like deep breathing, meditation, or visualization to ease anxiety ahead of sharing your identity. Helpful resources for coming out include: Trevor Project Lifeline (1-866-488-7386) TrevorSpace (an online community for LGBTQIA+ youth) OurCenter (a local community center for the LGBTQIA+ community in Reno) During the Coming Out Process: Staying Grounded The act of coming out can feel intimidating, as you’re sharing such a vital part of who you are. You might experience fear, panic, or doubt. While these feelings are real, know that you don’t have to navigate them alone. Tips for emotional resilience: Practice conversations ahead of time with a therapist or supportive friend so you feel ready when the time comes to share. Choose a time and place where you feel safe and in control. Use affirming statements, like, “I deserve to be loved for who I am.” Coping with negative responses: Set emotional boundaries with people who aren’t supportive. Create an emotional safety plan: know who you can call, where you can go, and what can help soothe you in moments of distress. After Coming Out: Processing and Healing Coming out, no matter how it went, deserves to be celebrated. An act of strength and authenticity like coming out is no small feat, so be proud of yourself for sharing who you are. Even so, the emotional aftermath can be complicated. You might feel joy and empowerment or loss and grief, especially if relationships shift. Healing strategies: Acknowledge your courage . Even difficult conversations are acts of strength. Rebuild your safety if you've experienced rejection. This might mean changing your environment or seeking new support systems. Release guilt or shame. Being who you are is never something you should feel ashamed or guilty for. Support networks can make a huge difference. Seek out different forms of support like: LGBTQIA+ support groups (in-person or online) Peer mentors or community leaders Allies, friends, or family who affirm and respect your identity Therapeutic options to deal with stress, grief, or isolation associated with coming out: EMDR (Eye Movement Desensitization and Reprocessing) can help process trauma. Narrative therapy helps you rewrite your story in your own empowering voice. Coming Out More Than Once: Navigating the Long Game Coming out isn’t just a single milestone, it’s a recurring process. You might come out again and again: to a healthcare provider, a neighbor, a partner, or a friend. It can feel exhausting or unfair to have to come out more than once, but each time, you’ll continue to find more strength, confidence, and understanding for yourself. Other tips for coming out: Focus on cultivating a strong inner identity that doesn’t rely on external validation. You know who you are, and you don’t need to prove yourself to anyone. Create a personal toolkit of coping and grounding strategies to deal with stress or burn-out associated with coming out.
