Understanding bulimia

Bulimia nervosa (bulimia, for short) was first identified as a problem in the early 80’s. It has attracted a variety of different definitions. Dr Catherine Sykes talks about the five key features of bulimia that are commonly used for diagnosis.

All five of these features should be present for a diagnosis of bulimia:

  1. Binge eating: eating more food in a single episode of eating than most people would normally eat in similar circumstances, there is a sense of loss of control overeating.
  2. Some action is taken to prevent weight gain such as self-induced vomiting, taking large quantities of laxatives or diuretics, extreme dieting, fasting, excessive exercising. This is often called ‘compensatory behaviours’.
  3. Binge eating and the compensatory behaviour both occur at least twice a week and have been going on for at least 3 months.
  4. Weight and shape play a large part in how the person evaluates themselves.
  5. The person is not very underweight.

 

What are the long-term effects of bulimia?

Bulimia affects many different parts of the body, including:

  • Teeth: vomiting exposes the teeth to acid which erodes the dental enamel and rots the teeth
  • Mouth: causes sore throats, mouth ulcers and bad breath
  • Face: the glands around the mouth swell and this makes the face round and chubby
  • Stomach: repeated vomiting weakens the oesophageal sphincter (the set of muscles at the top of the stomach) which can result in the contents of the stomach returning spontaneously into the mouth

 

Other symptoms include:

  • Low electrolytes: low potassium levels lead to heartbeat irregularities, extreme thirst, dizziness, fluid retention, weakness, lethargy, muscle twitches and spasms.
  • Osteoporosis: there is some research to suggest that bulimia may be associated with osteoporosis
  • Fatigue
  • Loss or disruption of the menstrual cycle

 

What can trigger bulimia?

Thoughts about your body, comparing yourself dis-favourably to someone else, having a bad day and restricting food can all trigger episodes of bulimia.

 

What is the best way to overcome bulimia?

CBT (cognitive behavioural therapy) is a good, established treatment for bulimia, with strong evidence for its effectiveness. It supports people with bulimia to consider and change the links between their thoughts, feelings and behaviour. It is a practical, problem-solving approach.

 

The triggers for a binge are considered and how this can be overcome by changing the person’s pattern of thoughts, feelings and behaviour. Some more experienced therapists will also help people with bulimia to understand how they have established the thought patterns that link to their episodes of bulimia.

 

What advice do you have for someone suffering from bulimia?

Dr Sykes advises someone suffering from bulimia to seek help. This can be a scary step but with the right support, addressing bulimia can be life-changing and the impact that vomiting has on the body can be reversed once bulimia is addressed.

 

To help someone to consider seeking help, Dr Sykes advises them to sit down with a pen and paper and write down the advantages of changing. She suggests paying attention to these advantages on a daily basis. Sometimes having a photo that reminds you of the advantages, as a screensaver can be motivational.

 

Dr Sykes also suggests that the person make note of their fears of changing. Then, once all the fears are noted, evaluate how likely it is on a scale of 0 -100% (0=highly unlikely, 100 = highly likely) that their fear will happen. To help evaluate the likelihood of their fear happening, the person should ask themselves:

  • What makes me think this?
  • Am I basing this prediction on one isolated incident?
  • Are others really concerned about my weight and shape as much as I am?
  • Could I be exaggerating?
  • Is this fear-based on other problems in my life?
  • Is it worth trying to change or even trying again to change?

 

Lastly, Dr Sykes suggests that the person go back to their fears and write new responses to them. Sometimes when we revisit what scares us or what once scared us, we realise that those fears aren’t so bad after all.
