What is anorexia?
While there is no single cause of anorexia nervosa, risk often starts when a child or teenager begins to significantly limit their food intake. Anorexia nervosa occurs when a child loses a significant amount of weight but still believes they are not thin enough or does not see the danger of their weight loss. They may even feel they have more weight to lose, so they continue to restrict food intake and may also increase exercise to speed up weight loss.
Anorexia nervosa can develop at any age, but it most often begins around puberty. Without intervention, the consequences of anorexia can be tragic. Untreated patients may suffer from slowed heart rate, increasing the risk for potentially fatal heart problems, as well as potentially permanent brain tissue loss. Girls can stop having periods, and the resulting lack of estrogen can lead to osteoporosis (weak bones), which occurs in 50% of patients with anorexia. Almost every organ system is affected by malnutrition caused by anorexia, including the brain, heart, liver, kidneys, bone marrow, skin and reproductive system.
The emotional complications of an eating disorder can be just as devastating as the physical complications. Relationships with family and friends often suffer as the child begins to avoid eating with others or resists efforts by others to help them. They often feel isolated and depressed. These conditions can lead to suicidality, the leading cause of death in people who suffer from eating disorders.
In addition to medical treatment, the family can be the first line of defense in fighting eating disorders. Learn more about family-based treatment (FBT) for eating disorders.
What causes anorexia?
Eating disorders do not have a single cause. They can develop from a combination of biological, psychological and social factors. Genetic vulnerability and family history of eating disorders or mood disorders can increase risk. Psychological factors such as perfectionism, low self-esteem, depression, anxiety and difficulty coping with intense emotions may be contributors.
Who gets anorexia?
Anorexia affects both boys and girls. People with anorexia often tend to be perfectionists or overachievers, excelling in school and engaging in myriad extracurricular activities.
Sometimes, preoccupation with weight starts in response to a stressful event, such as the loss of a friend or problems in the family. It may begin as a way to deal with general pressures such as growing up, fitting in socially, doing well in school or keeping everyone in the family happy.
What are the signs and symptoms of anorexia?
The symptoms of anorexia include significant weight loss as part of a drive to be thin, fear of weight gain and body image distortion (not perceiving appearance accurately, such as the belief that one is overweight, despite being very thin). Females may have a loss of menstruation.
Trusted adults, friends and family members may not realize the severity of their child’s illness until the person with anorexia becomes dangerously underweight. By this time, the affected person has severely limited what they will eat. They may exercise for hours every day as they adhere to a rigorous schedule to burn even more calories.
A person with anorexia usually denies they have an eating disorder and refuses to change their extreme diet, regardless of what those around them might caution or advise. Without professional intervention, the person will continue to lose weight, putting their health and life in serious danger.
Young people often go to great lengths to deny and conceal their struggles with food and weight. Here are some signs that may help you recognize anorexia in someone you know:
- Excessive weight loss. Anorexia is diagnosed when someone is significantly underweight, whether because of weight loss or failure to gain weight as they grow.
- Unusual eating habits. These may include taking tiny bites to stretch out eating time or compulsively arranging food on the plate.
- Avoiding family meals. The child might make excuses that they are too busy or eating elsewhere.
- Secretive behavior around eating and bathroom use. A teenager who habitually runs water, plays music or flushes the toilet repeatedly while using the bathroom may be masking the sounds of vomiting.
- Use of laxatives or diet pills. Taking any medication outside of recommended use can be dangerous to overall health.
- Excessive, and often obsessive, exercise. The child may attempt to burn calories consumed.
- Physical signs of malnutrition. These can include dull or thinning hair, hair loss, splitting or softening nails, extreme sensitivity to cold, dental cavities and gum disease.
- Absence of menstrual periods. This is related to loss of body fat.
- Appearance of fine body hair on arms and legs. This is a result of the body’s attempt to keep warm.
- Low self-esteem and/or mood changes. These may include irritability, depression, or talk of suicide.
- Distorted body image. No matter how thin the child becomes, they believe they are overweight.
- Drug or alcohol abuse. Teenagers with eating disorders may turn to substance abuse to relieve feelings of fear, shame, and depression.
How is anorexia treated?
Our approach to treatment gives families the support and education they need to manage anorexia and help their child work toward recovery, while minimizing time out of school and away from home.
For patients with significant medical concerns, an inpatient medical stabilization stay may be necessary before the family-based treatments below can safely begin.
We provide support to hundreds of children and teens, ages 6 to 18, each year. We offer customized treatment plans to meet each patient's unique needs.
We offer two program options:
- Day Treatment Program: Also known as Partial Hospitalization Program, this is designed for children and teens who need intensive support through eating disorder recovery but do not require 24-hour care. This typically is between 5 and 7 days, with some or all meals eaten in the program. A specialized care team guides families and children in developing healthy coping skills and supporting nutrition needs in their recovery process. Learn more about the Day Treatment Program.
- Outpatient Clinic: Includes individual, family and group therapy, as well as psychiatric medication management, as needed. If you’re not sure if outpatient services are right for your child, call us at 720-777-6200 to speak with our team. Learn more about the Outpatient Clinic.
The role of patents in meal planning and meal support
Much of our treatment approach is grounded in family-based treatment (FBT), an evidence-based treatment that helps parents identify and interrupt their child’s unhealthy behaviors and redirect them toward healthy habits. We equip parents with the skills they need to successfully support their children by managing meals, routines and emotions, all of which actively support their child’s recovery.
Parents learn how to plan balanced, nutrient-rich meals that support weight goals for their child. Mealtime becomes a focal point for working through challenges as parents develop strategies for addressing resistance, difficult emotions and disordered behaviors. By the time families transition out of the program and into outpatient support, parents will feel confident in continuing progress at home. By prioritizing family involvement, our program creates a sustainable and supportive path toward recovery together.

What can I do?
As a parent:
- Be a good role model. Set a family standard of eating meals together regularly and encouraging balanced eating and activity.
- Avoid negative comments about appearances and be aware of comments you make about yourself and family members. Stay positive and emphasize the whole person, not just how someone looks. Don't criticize or tease your child about minor weight gain and avoid power struggles over food.
- Help your child build healthy self-esteem. Give them opportunities to explore different interests and build confidence.
- Remember that no one is to blame when a child develops an eating disorder. Discuss your concerns openly, then seek professional help. A pediatrician or primary care provider is who most families start with when they become concerned.
As a friend:
- Don't comment on your friend's eating behavior or size. If your friend has had anorexia nervosa and gains weight, don't praise them for it.
- Remember that you can't solve the problem. You aren't responsible for saving your friend – you can be supportive and concerned, but encourage your friend to talk to a parent, teacher or counselor. If they don't, tell an adult close to your friend about your concerns.
As a school nurse, counselor, teacher or coach:
- Discuss your concerns with the child or adolescent first and suggest that he or she talks with their parents or caregivers.
- Expect denial of any problem. You may have to talk with the parents or caregivers but always let the adolescent know that you will be doing this and why.
