What Is Bulimia Nervosa?

Bulimia nervosa is a serious psychological condition in which a person experiences several episodes of binging and purging. It is characterized by eating food in large quantities with a loss of control over eating and then purging to get rid of the food.

To get rid of the calories and avoid gaining weight, people often use inappropriate and unhealthy ways like fasting, self-induced vomiting, enemas (injecting liquid or gas into the rectum through the anus to cleanse or expel the bowel), excessive use of laxatives (medications that speed up the movement of food through the body) and Diuretics (medication that leads to increased production of urine), using dietary supplements and herbal products to lose weight and, compulsive exercising. These episodes of binging and purging can happen many times a day.

A person with bulimia nervosa is never satisfied with their body even though they weigh in the normal range according to their age and height. This disorder is related to self-image. People judge themselves harshly for their self-perceived flaws. That is why they always binge in private, as they feel disgusted and ashamed of themselves. Such people are obsessed with food and their weight, and this can cause harm to their emotional and physical well-being. Bulimia nervosa usually tends to start in late childhood or early adolescence, and it can be hard to overcome. Though effective treatment can help in adopting healthy eating patterns making the person feel good himself or herself, and avoiding and reversing serious complications.

What Is the Treatment of Bulimia Nervosa?

The treatment plan is decided on the basis of the physical and psychological needs of the patient. In the treatment of bulimia nervosa patients, medical, nutritional, and mental health professionals are involved as a team.

1. Medical Help: Medicines help in the case of patients dealing with depression or anxiety. An FDA-approved drug for the treatment of bulimia is Fluoxetine (Prozac) which is an antidepressant. It also helps in reducing the desire to eat food abnormally. Hospitalization is required in patients with electrolyte imbalance and not in every patient with bulimia nervosa.

2. Psychotherapy: Psychotherapy treatment involves-

  • CBT (Cognitive Behavioral Therapy) - It is a type of individual counseling that involves teaching the patient proper eating habits, learning the things that are leading to binging and purging, and avoiding them. It also includes how the patient challenges unhealthy behavior and difficult situations. The patient is also made to learn the importance of self-love and avoid the fear of gaining weight.

  • Family-based Therapy - It is helpful when the patient is a child or teenager. The family is made to understand the condition and the complications it can cause and help them deal with it.

  • Interpersonal Psychotherapy - This therapy helps the patients understand social relationships and build them in a healthier way. This would help them to stabilize their emotional state and mental health.

3. Nutritional Therapy: With the guidance of a professional dietician, the patient is taught healthy eating habits and proper eating patterns according to his or her body’s signals toward food and hunger. This will help the patient to gain confidence as the body weight will get stabilized, and the patient will gain a healthy attitude toward food.

4. Self-care: Along with professional help, the patient has to concentrate on self-care too. This includes actively connecting with people socially, avoiding any triggers that cause the urge to binge eat and then purge, and looking after their bodies in healthier ways.

5. Support Groups: A support group is a congress of people who share their experiences, feelings, and issues while dealing with bulimia nervosa. Patients can benefit a lot from these conversations by getting motivated, loving themselves the way they are, and adopting a healthy lifestyle.

Conclusion:

Bulimia nervosa is considered hard to cure as its cause of it is unknown. However, it can be prevented if a proper and healthy lifestyle is maintained and people take care of their emotional and mental health. After bulimia nervosa is diagnosed, the main focus remains on how to prevent it from getting worse and the patient from harming himself or herself. Even after proper treatment, the rate of recurrence of bulimia nervosa is really high. It is the responsibility of people to look out for their friends or family members who might suffer from it and seek professional help immediately.
