Signs and Symptoms
People with bulimia may have the following signs and symptoms:
- Binge eating of large amounts foods, usually in secret
- Exercising for hours or using laxatives, diet pills, or water pills
- Eating until painfully full
- Going to the bathroom during or immediately after meals
- Avoiding eating in public
- Losing control over eating, and feeling guilt and shame
- Damaged tooth enamel and diseased gums
Bulimia nervosa is linked to depression and other mental disorders. It shares some symptoms with anorexia nervosa, another major eating disorder.
What Causes It?
There is no single cause for bulimia. Multiple factors contribute to the development of this disorder, including:
- Genetic factors - eating disorders are more common in people with relatives with eating disorders.
- Psychological factors - many people with eating disorders also experience depression, anxiety disorders, and obsessive-compulsive disorder.
- Cultural factors - cultural pressure to look thin may also play a part.
Who Is Most At Risk?
These people are at higher risk for developing bulimia:
- Women - about 90% of people with eating disorders are women.
- People who have first degree relatives with an eating disorder.
- People with a history of emotional and physical trauma, impulsive personality traits, or diagnoses of depression, anxiety, and obsessive-compulsive disorder.
What to Expect at Your Provider's Office
Often, people with bulimia are ashamed of their condition and do not ask for help for many years. If you have symptoms of bulimia, talk to your doctor as soon as possible.
- The doctor will check for physical signs such as tooth cavities, enamel erosion, diseased gums, and enlarged salivary glands.
- Laboratory tests may show chemical changes caused by abnormal eating.
- Your doctor or a mental health practitioner will do a psychological exam and ask about your feelings and eating habits.
People with bulimia may need a combination of treatment including:
- Family therapy
- Nutritional rehabilitation counseling
It is important for the person with bulimia to be actively involved in their treatment. Studies show cognitive behavioral therapy is remarkably effective in treating bulimia.
Doctors often prescribe antidepressants for bulimia, usually those called selective serotonin reuptake inhibitors (SSRIs). They include:
- Fluoxetine (Prozac)
- Sertraline (Zoloft)
- Paroxetine (Paxil)
- Fluvoxamine (Luvox)
Psychotherapy is a crucial part of bulimia treatment. Many people with bulimia have good results from cognitive behavioral therapy, which teaches you to replace negative thoughts and behaviors with healthy ones. Other psychotherapy approaches include interpersonal therapy, motivational enhancement therapy, and focal psychodynamic therapy. Family therapy is also an important component of recovery.
Complementary and Alternative Therapies
Mind-body and stress-reduction techniques, such as yoga, tai chi, and meditation may help you become more aware of your body and have a more positive body image.Nutrition and Supplements
Although there aren't any supplements that specifically treat bulimia, some may be good for your general health and well-being. Also, people with bulimia may fall short on some vitamins and minerals, which can affect their health. A better diet or taking supplements can help. Always tell your health care provider about any herbs and supplements you are thinking about using.
Follow these useful measures to overcome abnormal eating behaviors:
- Nutritional counseling
- Use of food diaries
- Planning meals one day in advance
Follow these nutritional tips for maintaining overall health:
- Avoid caffeine, alcohol, and tobacco.
- Drink 6 to 8 glasses of filtered water daily.
- Use quality protein sources -- such as lean meat and eggs, whey, and vegetable protein shakes -- as part of a balanced program to gain muscle mass and prevent wasting.
- Avoid refined sugars, such as candy and soft drinks.
If you have nutritional deficiencies, the following may be helpful:
- A daily multivitamin, as indicated by your doctor.
- Omega-3 fatty acids, such as fish oil, to help reduce inflammation and boost immunity. Cold-water fish, such as salmon or halibut, are good sources; eat 2 servings of fish per week. Fish oil supplements can increase the risk of bleeding, so ask your doctor before them. Eating fish doesn't cause the same risk.
- Coenzyme Q10, for antioxidant, immune, and muscular support. Pregnant and breastfeeding women should not take coenzyme Q. People who take blood pressure medication, blood-thinners such as warfarin (Coumadin), or chemotherapy drugs should not take CoQ10 without first asking their doctor.
- Probiotics (containing Lactobacillus acidophilus among other strains), to help your digestive health and boost the immune system. Refrigerate probiotic supplements for best results. People with autoimmune diseases, such as rheumatoid arthritis or psoriasis, or people with weakened immune systems should ask their doctor first.
There are no herbs proven as effective for treatment of bulimia.
People with eating disorders may misuse herbs or herbal supplements marketed as weight loss products. These products have not been tested for their safety and may have dangerous side effects. Products containing ephedrine alkaloids (such as Ephedra-containing herbal supplements) have been banned by the FDA due to serious health effects (such as stroke, seizures, and worsening of heart and kidney disease). However, other ephedra-free supplements may have similar side effects, especially when combined with caffeine, which causes heart rhythm problems. You should discuss with your health care provider before starting any treatment.Homeopathy
There are no studies on using homeopathy to treat bulimia.Acupuncture
Studies have found that acupuncture can be helpful in treating addictive behaviors and anxiety in general. That may help people with bulimia who are in recovery. One study had positive results on the improvement of quality of life in patients with bulimia using acupuncture in addition to their medical treatment.Physical therapy techniques
Physical therapy approaches, including massage, yoga, and relaxation techniques can be effective as adjunct treatments of bulimia nervosa.
Therapeutic massage can be an effective part of a bulimia treatment plan. In one study, 24 teen girls who got massage therapy for 5 weeks had better behavioral outcomes did better than a group of girls who didn't get massage and were less anxious and depressed than their counterparts.Bright light therapy
Bright light therapy (BLT) is a non-invasive treatment approach typically used for seasonal affective disorder and other types of depressive conditions. Because many people with bulimia binge-eat at night, BLT has repeatedly been tested as a potential therapy. Several studies demonstrated that BLT is effective in improving eating behaviors and mood in patients with bulimia nervosa.
It's very common for people with bulimia to relapse after treatment. They may need long-term care.
Possible complications resulting from bingeing and purging include problems with the:
- Teeth and gums
Women with bulimia may find pregnancy emotionally difficult because of the changes in their body shape. The mother's poor nutritional health can affect the baby. Women who have stopped having periods because of bulimia are unlikely to become pregnant.
People with suicidal thoughts or severe symptoms may need to be hospitalized.
Bulimia is usually a long-term disease. A health care provider will need to check the person's weight, exercise habits, and physical and mental health on an ongoing basis.
