1. A decline in oral health
Bulimia nervosa is characterized by binging episodes followed by self-induced purging. The most common form of purging is vomiting which involves not only the upchuck of unwanted calories in the form of partially digested food but also stomach acid that can have harmful effects on the esophagus and oral cavity including teeth and gums. The majority of individuals with bulimia nervosa will show signs and symptoms of tooth decay and cavities over time. Bringing acidic contents from your stomach into your mouth through self-induced vomiting can cause erosion of the enamel surface of your teeth. This damage usually appears primarily on the inside and biting surfaces of the teeth, and over time as the enamel is eroded by repeated exposure to gastric acid. For example, teeth may lose their shine, break, turn yellow, wear down, and chip. Stomach acid also potentiates the risk for cavities, and when combined with a high intake of sugary food, commonly seen in those who engage in binging, the risk for dental caries increases at a higher rate.
2. Consuming huge portions of food
Individuals with bulimia consume larger portions of food than what is considered normal over short periods. This behavior is often done in secrecy as many individuals cycle through feelings of loss of control followed by guilt and shame, which eventually results in compensatory behaviors, aimed at “undoing” calories consumed.
3. Unusual behaviors around meals
Consistently disappearing following a meal, especially to the bathroom, can be a sign indicative of bulimia. The same can be said for finding open wrappers or stashes of food in unusual places; for instance, opened packs of candy bars underneath one’s bed or in their closet. Excessive fluid intake after eating, especially water or diet soda, can be a precursor to certain purging behaviors. Regularly eating alone in private, avoiding social gatherings around food or showering immediately following meals are also possible causes for concern.
4. Excoriations and scars on the back of the knuckles and hands (Russell’s Sign)
Individuals who engage in self-induced vomiting as a compensatory behavior will often have excoriations on the back of the knuckles. Repeated contact of the fingers with teeth during self-induced vomiting episodes can lead to characteristic abrasions, small lacerations, and calluses on the back of the hand overlying the knuckles; formally known as Russell’s Sign.
5. Treatment for bulimia nervosa
Similar to anorexia nervosa and other eating disorders, bulimia nervosa is best treated by a professional eating disorder treatment center. Depending on the severity of the illness, levels of care range from inpatient treatment and residential treatment to partial hospitalization, intensive outpatient therapy, and outpatient treatment. A treatment plan is initiated immediately upon treatment admission, and this plan includes the components of the treatment team, psychotherapy approaches, nutritional and dietary counseling, and discharge and aftercare planning.
In the U.S., about 20 million women and 10 million men have eating disorders, so there’s a good chance someone you know is among them. They range from the more commonly known anorexia nervosa and bulimia to the lesser known binge-eating and restrictive food intake disorder. People who develop them often experience anxiety, low self-esteem and a level of perfectionism that makes them very hard on themselves.
Body dissatisfaction, especially concern about weight, is the strongest predictor of eating disorders. As the person attempts to achieve the perfect weight or shape—which is actually an effort to cope with intense emotions and stress—their relationships can become difficult.
Some people show subtle, early signs of eating disorders. These may include:
- Withdrawing from family or friends—avoiding situations that cause stress or anxiety. They may isolate themselves by not participating in social functions or activities they typically enjoy.
- A change in eating habits—eating alone, hiding food, eating slowly, or cutting/separating food into tiny pieces, for example. They might fixate on food and recipes and cook for others while restricting what they eat. There may be a pattern of eating when not hungry, eating to the point of discomfort, and experiencing depression, disgust or guilt after a meal.
- Body insecurity—negative or obsessive thoughts about body size or shape. It’s also common to obsess over calories or fat content in food. Men may worry about their muscularity and feel the need to “bulk up” or lose weight.
- Increased focus on body weight or shape—focusing more than usual on dieting or weight loss, possibly with a strict or excessive exercise routine performed even when they’re injured or fatigued. They may persistently worry or complain about being fat or feel they need to lose weight.
- Changes in appearance—significant or unusual weight loss or fluctuations, which may be the most obvious warning sign. They may deny having a low body weight. Other physical signs include puffy cheeks, knuckle calluses from vomiting, hair loss, dry hair or skin, sensitivity to cold, absent or irregular menstruation, excessive facial or body hair, unusual sleep patterns, or feeling faint or tired.
If someone you care about has changed their relationship with food, is skipping meals or making excuses for not eating, adopts an overly restrictive diet and/or exercise plan, or focuses obsessively on healthy eating, please consider whether it’s an eating disorder. Express your concerns in a forthright, caring manner. Find a safe, neutral, comforting place for both of you to talk and ask what would be most helpful. The person may deny problems, so it is important to keep the door open for future conversations.
Gently but firmly encourage them to seek professional help and offer to attend the evaluation appointment with them. If it’s your child, talk to your pediatrician or an eating disorder specialist.
Early intervention is critical for reducing the chance of chronic illness.
