Disordered eating

Disordered eating is a term that’s often used but not always well understood. Many people experience difficulties with food at some point in their lives, and these struggles don’t always fit neatly into a diagnosis. That doesn’t mean they aren’t important or worthy of support.

What is disordered eating?

Disordered eating describes a range of eating behaviours and attitudes that may negatively affect physical or emotional wellbeing but do not necessarily meet the criteria for a diagnosed eating disorder.

This can include:

• irregular or chaotic eating
• skipping meals
• rigid food rules
• anxiety around eating situations
• guilt or shame linked to food
• not prioritising food due to stress, low mood, or overwhelm
• using food as a way to control things

Disordered eating vs eating disorders

It’s important to understand the difference between disordered eating and an eating disorder.

Disordered eating:

• exists on a spectrum
• is very common
• may come and go
• does not always involve body image or weight concerns
• often improves with early support

Eating disorders:

• diagnosable mental illnesses (such as anorexia nervosa, bulimia nervosa, binge eating disorder, or ARFID)
• associated with significant psychological distress
• involves concerns about shape and weight
• usually require specialist treatment

Disordered eating does not mean someone has an eating disorder, but it can increase risk over time if left unaddressed. Early support can be protective.

Common signs and symptoms

Disordered eating can look different from person to person. Some common signs include:

Changes in eating patterns

• skipping meals or eating very irregularly
• cutting out whole food groups without medical reason
• rigid rules around food or ingredients
• avoiding eating with others

Thoughts and feelings around food and body

• frequent worry about food, eating, or appearance
• guilt, shame, or anxiety after eating
• “all-or-nothing” thinking around food
• comparing eating habits or bodies with others

Emotional and behavioural changes

• increased irritability, anxiety, or low mood
• reduced energy or concentration
• withdrawal from social situations involving food
• changes in confidence linked to body image

These signs don’t confirm a diagnosis, but they can indicate that someone is struggling.

Possible side effects of disordered eating

Over time, disordered eating can affect both physical and emotional wellbeing, including:

• low energy and poor concentration
• mood changes such as irritability or anxiety
• disrupted routines and social withdrawal
• increased preoccupation with food or body
• a more strained relationship with eating

The impact isn’t always visible from the outside, which is why disordered eating can go unnoticed for a long time.

Why disordered eating develops

There is no single cause. Disordered eating often develops due to a combination of factors, such as:

• body image pressure and comparison
• social media and diet culture
• stress, anxiety, control, or low mood
• transitions or loss of routine
• perfectionism or high expectations
• sensory sensitivities or neurodivergence

Understanding the function of the behaviour, what it’s helping someone cope with is often more helpful than focusing on food alone.

Disordered eating and SEND (including autism)

It is important to recognise that not all disordered eating behaviours are driven by body image or weight concerns. For some people, particularly those with SEND, eating differences may be linked to neurodevelopmental needs rather than an eating disorder.

Autism and eating differences

Autistic pupils may experience eating difficulties due to factors such as:

• Sensory sensitivities (texture, taste, smell, temperature, or appearance of food)
• Black-and-white or rigid thinking, leading to strong food rules or limited food choices
• Anxiety around change, making new foods or changes to routine distressing
• A need for predictability and sameness, including eating the same foods repeatedly

These patterns can look like disordered eating from the outside, but they are not necessarily linked to body image, weight, or a desire to change appearance.

How to Seek Help for Yourself

If you recognise some of these patterns in yourself:

• remind yourself that you don’t need to be “ill enough” to ask for help
• consider speaking to a trusted person (friend, family member, teacher)
• seek support from a GP, counsellor, or specialist professional who’s trained in both disordered eating and eating disorders
• focus on restoring regular nourishment and support, not fixing or controlling food

Early support can prevent difficulties from becoming more entrenched.

How to support a friend

If you’re worried about someone else:

• approach them gently and privately
• focus on how they seem to be feeling, rather than what they’re eating
• avoid giving advice or trying to “fix” the problem
• encourage them to talk to a trusted adult or professional
• remember it’s okay to seek help even if they’re unsure

You don’t have to carry concern alone.

Final thoughts

Disordered eating is not a failure, a phase to ignore, or something that needs to reach crisis before it’s taken seriously. It’s often a signal that someone needs support, understanding, and care.

The earlier difficulties are recognised and responded to, the better the outcomes for both physical health and emotional wellbeing.

If you or someone you care about is struggling, reaching out can be a powerful first step.
