What are the dangers of bulimia nervosa

Think you or a loved one may have bulimia? Bulimia is a serious eating disorder that not only causes short-term problems to an individual’s health and quality of life but can also have severe (even life-threatening) effects on a person’s long-term health.

What is Bulimia?

Bulimia nervosa is an eating disorder characterized by frequent episodes of bingeing (eating a large amount of food in a short period of time) followed by purging (self-induced vomiting, use of laxatives or diuretics, exercising, fasting, etc.) [1].

Though the physical consequences of bulimia may not be as visibly obvious as in other eating disorders like anorexia nervosa (.g. extreme weight loss), bulimia is just as serious of an eating disorder. Not only does bulimia put an extreme burden on a person’s emotional and mental health (it is a mental health disorder, after all), it can also lead to severe short-term and long-term health problems.

Short Term Consequences

Some of the short term consequences of bulimia include the following:

  • Severe dehydration
  • Electrolyte imbalances
  • Anemia
  • Fatigue
  • Sore throat
  • Stomach pain
  • Constipation
  • Irregular heart rhythm
  • Amenorrhea (absence of menstruation)
  • Cavities
  • Swollen salivary glands in the jaw or neck
  • Hair loss
  • Dry skin
  • Intestinal issues
  • Acid reflux
  • Sleep problems
  • Dizziness
  • Depression

If treated in a timely manner, many of the short-term consequences of bulimia will diminish or completely disappear once the individual gets medical help and recovers from bulimia. However, since bulimics don’t typically conform to the traditional “eating disorder image” (severely underweight) and because they often hide their binge-purge behaviors from others, their friends, family, doctors, and even the individual themself may fail to realize they have a serious eating disorder until the condition has progressed to a dangerous level. Unfortunately, if bulimia is left untreated for too long, the short-term consequences listed above can lead to serious, long-term health problems that may not easily clear up or go away once the person stops bingeing and purging.

Long Term Consequences

As bulimia progresses, the effects of bingeing and purging start to cause more severe and permanent damage to the body. For example, when the body isn’t getting enough calories from food, it starts consuming muscle. If this goes on long enough, the heart (the body’s most important muscle) will begin to weaken, which can eventually lead to coronary heart disease and even death [2].

Another long-term effect of bulimia is esophageal issues. Purge vomiting can cause the esophagus to tear and become weak, which can then lead to a host of problems, including chronic acid reflux. Thanks to the stomach acids involved in acid reflux, the mucous membranes of the esophagus may eventually begin to erode, causing a condition known as Barrett’s esophagus. This can then lead to the development of esophageal cancer.

Some of the other long-term consequences of bulimia include:

Throat Damage

  • Weakness in the esophageal sphincter
  • Tearing of the esophagus
  • Gastroesophageal reflux disease (chronic acid reflux)
  • Esophagitis (inflammation of the esophagus that can lead to scarring)
  • Esophageal cancer

Other long-term consequences of bulimia include damage to the kidneys, increased risk of kidney stones and kidney failure, diabetes, high cholesterol, hormonal imbalances, fertility problems, chronic dehydration, chronic fatigue, and electrolyte imbalances.

Treating the Long Term & Short Term Consequences of Bulimia

Fortunately, many of the short-term consequences of bulimia can be treated and reversed once appropriate medical care is received and bulimia behaviors cease. However, if left untreated, bulimia can lead to a host of serious health problems that may persist for years to come.

If you think you or a loved one may have bulimia, take the first step today and seek immediate medical help. Start by talking to your doctor about bulimia or call the National Eating Disorders Association helpline at 1-800-931-2237 to find out more about treatment options in your area.

Bulimia is an eating disorder and mental health condition.

People who have bulimia go through periods where they eat a lot of food in a very short amount of time (binge eating) and then make themselves sick, use laxatives (medicine to help them poo) or do excessive exercise, or a combination of these, to try to stop themselves gaining weight.

Anyone can get bulimia, but it is more common in young people aged 13 to 17.

Symptoms of bulimia include:

  • eating very large amounts of food in a short time, often in an out-of-control way – this is called binge eating
  • making yourself vomit, using laxatives, or doing an extreme amount of exercise after a binge to avoid putting on weight – this is called purging
  • fear of putting on weight
  • being very critical about your weight and body shape
  • mood changes – for example, feeling very tense or anxious

These symptoms may not be easy to spot in someone else because bulimia can make people behave very secretively.

Getting help and support as soon as possible gives you the best chance of recovering from bulimia.

If you think you may have bulimia, see a GP as soon as you can.

They'll ask you questions about your eating habits and how you're feeling, and will check your overall health and weight.

If they think you may have bulimia or another eating disorder, they should refer you to an eating disorder specialist or team of specialists.

It can be very hard to admit you have a problem and ask for help. It may make things easier if you bring a friend or loved one with you to your appointment.

You can also talk in confidence to an adviser from the eating disorders charity Beat by calling their adult helpline on 0808 801 0677 or youth helpline on 0808 801 0711.

Getting help for someone else

If you're concerned that someone close to you may have bulimia, let them know you're worried about them and encourage them to see a GP. You could offer to go along with them.

Read more about talking to your child about eating disorders and supporting someone with an eating disorder.

You can recover from bulimia, but it may take time and recovery will be different for everyone.

Your treatment plan will be tailored to you and should take into account any other support you might need, such as for depression or anxiety.

If you're over 18, you'll probably be offered a guided self-help programme. This involves working through a self-help book, and often includes keeping a diary and making a plan for your meals.

You'll be supported by a therapist during this process. You may also be offered cognitive behavioural therapy (CBT).

If you're under 18, you may be offered family therapy as well as CBT.

Bulimia can eventually lead to physical problems associated with not getting the right nutrients, vomiting a lot, or overusing laxatives.

Possible complications include:

  • feeling tired and weak
  • dental problems – stomach acid from persistent vomiting can damage tooth enamel
  • bad breath, a sore throat, or even tears in the lining of the throat – also caused by stomach acid
  • irregular or absent periods
  • dry skin and hair
  • brittle fingernails
  • swollen glands
  • fits and muscle spasms
  • heart, kidney or bowel problems, including permanent constipation
  • bone problems – you may be more likely to develop problems such as osteoporosis, particularly if you have had symptoms of both bulimia and anorexia

We do not know exactly what causes bulimia and other eating disorders.

You may be more likely to get an eating disorder if:

  • you or a member of your family has a history of eating disorders, depression, or alcohol or drug addiction
  • you have been criticised for your eating habits, body shape or weight
  • you're overly concerned with being slim, particularly if you also feel pressure from society or your job
  • you have anxiety, low self-esteem or an obsessive personality
  • you have been sexually abused

Binge-purge cycle

Bulimia is often a vicious cycle of binging and purging, triggered by things such as hunger, sadness or stress.

You may set very strict rules for yourself about dieting, eating or exercising.

Failing to keep to these then leads to periods of excessive eating and loss of control (binge eating), after which you feel guilty or ashamed.

You then purge to get rid of the calories, leaving you feeling hungry again, and the cycle continues.

This video explores how to spot the symptoms of bulimia nervosa, and how it can impact someone's life.
