Other dangers of eating disorders

Co-morbid mental health problems

Eating disorders are often accompanied by other mental health conditions, such as depression, anxiety, bipolar disorder, obsessive compulsive disorder, substance use disorders and borderline personality disorder.^[1] Treatment for eating disorders may also include treatment for an additional mental health issue.

Addiction

There are strong links between eating disorders and addiction. Eating disorders could in themselves be described as addictions, defined as a compulsive need to carry out some kind of harmful behavior that is difficult to stop^[6]. Addiction is related to the reward center of the brain. For example, when we take drugs or consume alcohol it affects our brain chemistry which in turn makes us feel pleasure. The same sorts of effects have been found in the brains of people when they are restricting, binging, or purging.^[7] In addition, some people with eating disorders use alcohol or stimulants as a way of suppressing their appetite and controlling their body weight ^[1], which may over time lead to addiction.

Risk of death

Eating disorders carry with them an increased risk of death.^[2] This varies between different kinds of eating disorder. The risk of death is increased for several reasons:

• Complications arising from starvation and malnutrition
• An elevated risk of health problems including heart disease, stroke, and cancer
• Substance misuse
• Suicide

Getting help

If you believe that you have an eating disorder, seek help as soon as you can. Most people with eating disorders don’t recover without support^[8], so while there are things you can do to manage your condition, seeking professional help is important.

The first call could be your doctor, who can make an initial assessment and refer you to a. specialist mental health for support.

Eating disorder treatment is usually based around psychotherapy. Hospitalization is sometimes necessary, and medication may be prescribed to treat an underlying or accompanying mental health problem, such as depression or anxiety.
