The Dangerous Relationship Between Eating Disorders and Malnutrition

Thrive • October 8, 2021

Malnutrition is characterized by deficiencies, excesses, or imbalances in a person’s intake of nutrients, which are essential for the body to function properly. Eating disorders including anorexia nervosa, bulimia nervosa, and binge eating disorder (BED) can disrupt the body’s nutrient balance, resulting in a lack of energy for the body to carry out vital processes. 

Malnutrition can have serious and even deadly health consequences, especially when brought on by eating disorders. Investigators found that mortality rates were 4 percent for anorexia nervosa, 3.9 percent for bulimia nervosa, and 5.2 percent for unspecified eating disorders. Though these statistics don’t take into account eating disorder deaths related to malnutrition, they underscore the perilous nature of eating disorders and their potentially deadly effects.

THIRTEEN HEALTH CONSEQUENCES OF EATING DISORDERS RELATED TO MALNUTRITION

Many of the health consequences related to eating disorders are due in large part to malnutrition, which can be caused by limited caloric intake, purging, as well as excessive caloric intake. 

Explore the consequences of malnutrition brought on by eating disorders below:

  1. Heart failure — Can result when the body breaks down the heart in an attempt to use its own muscle tissue for fuel; also can be caused by a decrease in electrolytes which help the heart beat.
  2. Slowed digestion — Caused by the interference with the normal emptying of the stomach following eating. Associated issues of slowed digestion can include:
    • Stomach pain and bloating
    • Nausea and vomiting
    • Blood sugar fluctuations
    • Blocked intestines
    • Bacterial infections
    • Feeling full after eating only small amounts
  3. Constipation — Due to the weakening of the muscles of the intestines that leaves them without the strength to move food out of the body.
  4. Pancreatitis — An inflammation of the pancreas that can cause symptoms of pain, nausea, and vomiting.
  5. Decreased brain functioning — The brain relies on one-fifth of the body’s calories to function. Without the necessary energy, the depleted brain can cause sleep issues, seizures, and fainting.
  6. Decreased hormone levels — A lack of fat in one’s diet can result in diminished levels of estrogen, testosterone, and thyroid hormones, causing irregular menstruation and bone loss.
  7. Decreased metabolic functioning — Can affect the body’s ability to stay warm, leading to hypothermia.
  8. High cholesterol levels — Malnutrition can affect the liver’s ability to metabolize cholesterol. High cholesterol can also result from abnormal hormone levels brought on by anorexia. 
  9. Dry skin, brittle hair, and hair loss — Due to a lack of fat and nutrients in one’s diet.
  10. Growth of lanugo — A kind of hair grown by the body to help it stay warm when facing starvation.
  11. Kidney failure — Can result from severe dehydration.
  12. Decrease of certain blood cells — Which can threaten the body’s ability to fight infections.
  13. Anemia — Caused by diminished iron in one’s diet which can result in fatigue, weakness, and shortness of breath.

The Greenhouse at Thrive Wellness A New Chapter of Hope and Healing in Nevada On Friday, November 14 , we gathered with our partners at Molina Healthcare to share an important moment for our community. Together, we celebrated Molina’s generous $50,000 grant , an investment that is helping bring The Greenhouse to life. Their support is not only a financial contribution—it’s a statement of belief in the young people and families of Nevada who deserve access to compassionate, evidence-based mental healthcare close to home. This gathering marked the beginning of something we’ve dreamed about for years: a place designed specifically for adolescents and emerging adults to receive the care, connection, and support they need during some of the most vulnerable moments of their lives. Something New Is Growing In early 2026 , Thrive Wellness will open The Greenhouse , Nevada’s first residential treatment center devoted to adolescents and emerging adults navigating eating disorders, anxiety, and OCD . For too long, families have faced a heartbreaking dilemma—send their child far from home for treatment or go without the specialized care they need. The Greenhouse is our answer to that gap. It will be a place where young people can settle into an environment built for healing, where they are understood, supported, and surrounded by a team that believes in their capacity to recover. The Greenhouse represents a natural extension of our mission. It’s a living expression of our belief that recovery is possible—and that with the right support, families can find their footing again.

Eating disorders are one of the most serious mental health concerns facing today’s adolescents. They can affect every aspect of a young person’s life, including their physical health, school performance, relationships, self-esteem, and more. According to the National Institute of Mental Health, about 2.7% of adolescents in the U.S. will experience an eating disorder in their lifetime, and many more engage in disordered eating behaviors that may not meet full diagnostic criteria. The good news is that providers are in an influential position to notice early warning signs, open conversations, and connect families to support before these patterns of behavior become too engrained. Why Early Intervention Matters The earlier an eating disorder is identified and treated, the better the treatment outcomes. Research shows that getting support quickly after the disorder’s onset is linked to faster recovery, lower relapse rates, and healthier long-term development (Treasure & Russell, 2011). Waiting too long to seek help can mean medical complications, deeply ingrained behaviors, and a more difficult path to healing. For many adolescents, a caring provider who notices the signs and advocates for treatment can make all the difference in recovery and can even save lives. Recognizing Early Warning Signs Adolescents may not always disclose their struggles directly, so providers should keep an eye out for a range of indicators: Physical signs: noticeable weight changes, menstrual irregularities, digestive issues, dizziness, or fatigue. Behavioral patterns: skipping meals, restrictive eating, excessive exercise, frequent dieting, eating in secret, or leaving for the bathroom after meals. Emotional and cognitive signs: preoccupation with weight or body shape, food rituals, heightened anxiety around eating, or perfectionistic tendencies. It’s important to remember that eating disorders don’t always “look” a certain way. Teens can be distressed about food and body image even if their weight appears to be within a “normal” range. Screening Tools and Assessments Using free screening tools available online can be an effective way to gauge a patient’s needs and gain further insight on treatment options for a possible eating disorder. Here are 4 free screening resources we recommend you use before making a referral for a higher level of care. EDE-Q (Eating Disorder Examination Questionnaire) : helps assess eating attitudes and behaviors. Nine Item Avoidant/Restrictive Food Intake disorder screen (NIAS) : helps to assess the signs of ARFID in children. Eat 26 Screening Tool : a screening measure to help you determine attitudes towards food and eating. BEDS-7 (Binge Eating Disorder Screener) : for situations where binge eating is suspected. When possible, gathering input from parents, teachers, or coaches can also help, as teens may minimize their experiences out of fear or shame. The Role of Primary Care and Pediatric Providers Routine checkups are often where eating disorders first come to light. Providers treating children, teen, and adolescents can: Incorporate simple questions about eating habits and body image into wellness visits. Track growth charts and weight trends while pairing them with questions about mood, anxiety, and behavior. Foster trust by creating a safe, nonjudgmental space where adolescents feel comfortable sharing sensitive information and know there will be no weight stigma. Coordinating Multidisciplinary Care Supporting a young person with an eating disorder works best when care is collaborative . In order to treat the whole person, there are usually multiple members of a treatment team needed, including: Medical support: monitoring vital signs, lab work, and physical health. Therapeutic care: evidence-based approaches such as family-based therapy (FBT) and cognitive-behavioral therapy (CBT) help address thoughts and behaviors. Nutritional guidance: dietitians provide education, meal support, and reassurance. Family involvement: engaging caregivers empowers them to support recovery in everyday life. Addressing Barriers and Stigma Many families face challenges in seeking help, whether due to stigma, lack of awareness, or limited access to specialists. To help, providers can: Normalize conversations about body image and mental health as part of overall well-being. Use culturally sensitive approaches that honor diverse experiences with food, body, and health. Connect families to community organizations, online resources, or telehealth when in-person specialty care is limited. Eating disorders in adolescents are serious, but with early recognition and timely support, recovery is possible. Providers are often the first to notice changes and can play a vital role in opening doors to crucial support. By blending professional expertise with empathy and collaboration, providers can guide adolescents and their families toward lasting recovery and a healthier future.
