Food touches almost everything about daily life, so an eating disorder can hide in plain sight for a long time. A daughter who suddenly cuts out whole food groups, a partner who disappears to the bathroom after every meal, a colleague who talks endlessly about clean eating but seems to be fading away. By the time someone close starts to worry, the illness has often had months or years to take hold.
Eating disorders are serious mental illnesses, not vanity, willpower problems, or a phase. They affect people of every age, gender, body size, and background, and they carry some of the highest mortality rates of any psychiatric condition. The good news is that they respond to treatment, especially when help comes early, and there are specialist services in South Africa and beyond that exist for exactly this.
What an eating disorder actually is
An eating disorder is a mental health condition marked by a serious disturbance in eating behaviour, usually tied to intense distress about food, weight, or body shape. According to the National Institute of Mental Health, these are real, treatable medical illnesses, and people living with them face a higher risk of medical complications and of other conditions developing alongside, including depression, anxiety, and substance use disorders.
The thoughts behind the behaviour matter as much as the behaviour itself. Many people experience a distorted body image, seeing themselves as larger than they are even when they are dangerously underweight. Others feel a loss of control around food, followed by deep shame. None of this is chosen, and none of it reflects a person’s character.
The main types of eating disorders
Eating disorders show up in different ways, and someone can move between patterns over time. These are the ones clinicians see most often.
Anorexia nervosa
Anorexia involves severe restriction of food, an intense fear of gaining weight, and a body image that does not match reality. It often comes with excessive exercise and rigid rules around eating. Long term, it can cause malnutrition, heart and kidney problems, and bone loss. The World Health Organization notes that anorexia nervosa usually begins in adolescence or early adulthood and carries a real risk of early death, both from medical complications and from suicide.
Bulimia nervosa
Bulimia is a cycle of binge eating followed by attempts to undo it, through self-induced vomiting, laxatives, fasting, or punishing exercise. The bingeing usually feels out of control, and the purging is driven by guilt and fear. The WHO links bulimia with a higher risk of substance misuse and suicidal behaviour, which is part of why it should never be dismissed as a habit someone can simply stop.
Binge-eating disorder
Binge-eating disorder involves repeated episodes of eating large amounts of food, often quickly and in secret, with a sense of being unable to stop. Unlike bulimia, there is no regular purging afterwards. People often feel intense guilt, embarrassment, and distress. It is one of the most common eating disorders, and it can affect people of any body size.
Other recognised patterns
- Avoidant or restrictive food intake disorder (ARFID): avoiding food or limiting how much is eaten, often due to texture, fear of choking, or lack of interest in eating, rather than concern about weight.
- Pica: persistently eating things that are not food, such as soil, chalk, or paint chips.
- Rumination disorder: repeatedly bringing food back up and re-chewing or swallowing it.
Warning signs worth paying attention to
Eating disorders are often kept hidden, so the early signs can be easy to explain away. Some patterns to watch for in yourself or someone you care about:
- Skipping meals, eating in secret, or strict rules about what is and is not allowed
- Frequent trips to the bathroom soon after eating
- Preoccupation with weight, calories, body shape, or “clean” eating
- Noticeable weight changes, or no expected weight gain in a young person who is still growing
- Withdrawing from meals, social events, and friends
- Low mood, irritability, anxiety, dizziness, or exhaustion
One sign on its own is rarely proof of anything. A cluster of them that persists is worth taking seriously, and worth a conversation with a doctor or mental health professional.
Where addiction and eating disorders overlap
Freeman House Recovery is a private drug and alcohol rehabilitation centre, and we do not treat eating disorders as a standalone, primary condition. We are including this because the overlap with substance use is genuine and often missed, and because the people who reach us, or their families, sometimes need to understand both at once.
The connection is well documented. The same research that recognises eating disorders as serious illnesses also notes how frequently they sit alongside depression, anxiety, and substance use. Some people use alcohol or drugs to numb the distress that drives disordered eating. Others develop disordered eating during recovery from a substance, when food becomes the thing they try to control. When two conditions feed into each other like this, treating only one tends to leave the other free to pull a person back.
This is the territory of dual diagnosis, where a substance use disorder and a mental health condition are present together and need to be understood as connected rather than separate problems. It overlaps with the wider relationship between drug addiction and mental health disorders, and with the way behavioural patterns and mental health interact. Where an eating disorder is the primary concern, though, the right step is specialist eating disorder care, which we point to below.
How eating disorders are treated
There is no single fix, and recovery is rarely a straight line. Effective treatment usually brings together several kinds of support, matched to the person and how unwell they are.
Psychotherapy
Talking therapy with a clinician who specialises in eating disorders is central to most treatment plans. It helps a person recognise the thoughts and beliefs feeding the illness and build healthier ways of coping. Cognitive behavioural therapy is one of the better-studied approaches, and other methods such as family-based treatment are widely used, particularly for younger people.
Medical and nutritional care
Because eating disorders affect the whole body, medical monitoring is often needed, sometimes urgently. Restoring nutrition safely, with guidance from a dietitian and a doctor, is a treatment in its own right, since a starved or chaotic body cannot heal psychologically either.
Medication where appropriate
Medication is not a cure for an eating disorder and rarely works on its own. For some people it can help manage co-occurring depression, anxiety, or other symptoms as part of a broader plan. That is a decision for a prescribing doctor who knows the full picture.
Family involvement
Eating disorders affect whole families, and families are often part of the recovery. The right support helps loved ones understand what they are seeing and respond in ways that help rather than harm. This mirrors what we see across recovery generally, where family support can make a real difference.
Where to find specialist help in South Africa
If an eating disorder is the main concern, specialist support is the right starting point. A few places to begin:
- Speak to your GP, who can assess physical health and refer you to a psychologist, psychiatrist, or dietitian experienced in eating disorders.
- Contact the South African Depression and Anxiety Group (SADAG) for free telephone counselling, referrals, and support groups across the country.
- Read trusted background information from the National Institute of Mental Health to understand symptoms and treatment options.
If alcohol or drug use has become tangled up with disordered eating, that part of the picture is something we can help with directly.
Frequently Asked Questions
Are eating disorders a mental illness or a choice?
They are recognised mental illnesses, not choices or a lack of discipline. They involve real changes in thinking, mood, and behaviour, and they need proper treatment, not willpower.
Can eating disorders be treated?
Yes. Eating disorders respond to treatment, and recovery is possible, particularly when help comes early. Care usually combines psychotherapy, medical and nutritional support, and sometimes medication for co-occurring conditions.
Does Freeman House Recovery treat eating disorders?
Our primary service is inpatient treatment for drug and alcohol addiction. We do not treat eating disorders as a standalone condition, so for a primary eating disorder we encourage you to seek specialist eating disorder care. Where substance use and disordered eating occur together, we can help with the addiction side and work alongside the wider support a person needs.
Why do eating disorders and substance use sometimes go together?
Both can be ways of managing painful emotions, and each can develop into or worsen the other. Research consistently links eating disorders with a higher risk of substance use, which is why it helps to look at the whole person rather than one symptom in isolation.
If you are worried, reach out
Noticing a problem, in yourself or someone you love, is hard, and it can take real courage to say it out loud. You do not have to have all the answers before you ask for help. A first phone call to a GP or to SADAG is enough to start.
If addiction is part of what you are facing, the team at Freeman House Recovery is here to talk it through, gently and without judgement. You can reach us on +27 12 1111 739 to ask questions and find out what support might look like.
