Bulimia nervosa is an eating disorder that can go unnoticed for a long time. Many of the signs of bulimia are subtle rather than obvious, which makes them easier to overlook even by those who are close to someone struggling.
This article sets out the behavioural, physical, and emotional signs of bulimia that are commonly missed, along with practical guidance on approaching a loved one you’re concerned about. Recognising the early signs of bulimia, and knowing how to respond, can make a real difference to the treatment someone receives.
Understanding the behavioural signs of bulimia
Spotting signs of bulimia in others can be particularly difficult, as many of the behaviours associated with the illness are designed to stay hidden. The changes below are often among the first that friends and family members notice.
Changes in eating habits & routines
Someone experiencing bulimia may develop rigid rules around food, eat unusually large amounts in one sitting, or swing between restricting food and eating much more than intended. These changes are often followed by feelings of distress or a strong urge to compensate, which can include vomiting or the use of laxatives. You may also notice a growing collection of wrappers or missing food, or a reluctance to eat in front of other people.
Secrecy around food and frequent bathroom trips
Frequent trips to the bathroom shortly after meals, particularly if accompanied by running water or music to mask sound, can be a sign of bulimia. Someone may also become secretive about what, when, or how much they are eating and go to greater lengths to eat alone.
Social withdrawal and avoidance of meals
Occasions that involve food, such as meals out, celebrations, or family dinners, may increasingly be avoided or cancelled at short notice. Over time, this can lead to broader social withdrawal, as maintaining routines around food becomes harder to manage around other people.
Spotting the physical signs of bulimia
The physical signs of bulimia often develop gradually as a result of repeated cycles of bingeing and vomiting, and they can easily be mistaken for unrelated health issues.
Dental problems and sore throats
Frequent contact with stomach acid can wear away tooth enamel over time, leading to increased sensitivity, discolouration, or a higher rate of cavities. A persistent sore throat, hoarse voice, or swollen glands can also be a sign worth paying attention to, particularly if it doesn’t have another obvious cause.
Russell’s sign (calluses on knuckles)
Russell’s Sign refers to calluses, scarring, or scrapes on the back of the hand or knuckles, caused by repeated contact with the teeth. Named after the psychiatrist who first documented it, this can be one of the more visible physical signs of bulimia, though it isn’t present in every case.
Weight fluctuations and dizziness
Weight can fluctuate noticeably, though many people experiencing bulimia stay within an expected weight range, so this sign is often missed or dismissed. Dizziness, fatigue, and light-headedness are also common and can be linked to dehydration or electrolyte imbalances caused by vomiting.
Swollen cheeks or jawline
Swelling around the jaw or cheeks, caused by enlarged salivary glands, is another physical sign of bulimia that can develop with repeated vomiting. This swelling may come and go, which can make it harder to notice consistently.
Recognising emotional and psychological changes
Alongside behavioural and physical signs, bulimia is often accompanied by significant emotional and psychological changes.
Intense fear of gaining weight
A persistent and often overwhelming fear of gaining weight is a common feature of bulimia. This fear can shape daily decisions around food, exercise, and social plans and may not ease even when someone’s weight hasn’t changed.
Negative body image and low self-esteem
Bulimia is frequently linked to a distorted perception of body shape or size and self-worth that has become closely tied to weight or appearance. This can show up as frequent negative comments about the body, checking behaviours such as repeated weighing, or avoidance of mirrors and photographs.
Mood swings, anxiety, or depression
Low mood, irritability, and heightened anxiety, particularly around food and mealtimes, are common alongside bulimia. These emotional changes can also be a response to the exhaustion and shame that often accompany the cycle of bingeing and vomiting.
What to do: how to help someone you suspect has bulimia
If you’ve noticed several of these signs of bulimia in someone you care about, it’s natural to feel unsure about what to say or do next. A calm, supportive approach makes it easier for the conversation to open a door, rather than close one.
Choose the right time and place to talk
Find a private, unhurried moment away from mealtimes to raise your concerns. Approaching the conversation gently and without an audience gives the other person space to respond honestly, without feeling put on the spot.
Focus on your concerns, not on their weight
Centre the conversation on how the person seems to be feeling, rather than on their weight or appearance. Comments about weight, even well-intentioned ones, can add to feelings of shame and make someone less likely to open up.
Encourage professional help
Let the person know that support is available and that reaching out for professional help is a sign of strength, not failure. You can offer to help them find the right service or to go with them to a first appointment if that would help.
FAQs: bulimia
What are the early signs of bulimia?
Early signs of bulimia can include a preoccupation with food, body shape, or weight, eating in secret, disappearing to the bathroom after meals, and mood changes around eating occasions. These early signs are often subtle and may be mistaken for stress or a passing phase, which is why they can be difficult to spot.
How can I spot signs of bulimia in others?
Signs of bulimia in others are often easier to notice through a pattern of changes over time, rather than a single moment. Look out for shifts in eating habits, avoidance of meals with others, frequent trips to the bathroom after eating, and signs of low mood or anxiety connected to food.
Can someone with bulimia have a stable weight?
Yes. Many people experiencing bulimia maintain a weight within an expected range, which is one of the reasons the condition can be so difficult to identify from physical appearance alone.
How is bulimia diagnosed?
A diagnosis of bulimia is made by a qualified healthcare professional, based on a full assessment of eating patterns, behaviours, and their impact on physical and emotional wellbeing. If you’re concerned about yourself or someone else, a GP is a good first point of contact.
What should I do if I recognise these signs in myself?
If you recognise these signs in yourself, reaching out to a GP or a specialist eating disorder service is a positive first step. Support is available at every stage, and recovery is possible with the right treatment plan in place.
