Eating Disorders Blood Test

What is Eating disorders?

Eating disorders are complex mental health conditions including anorexia nervosa, bulimia nervosa, and binge eating disorder that severely impact physical health. They are caused by a combination of psychological, genetic, and environmental factors that lead to restrictive eating, purging behaviors, and severe malnutrition. The Sex Hormone Binding Globulin (SHBG) test is the most important test for assessing hormonal complications from eating disorders.

What causes eating disorders?

Eating disorders are caused by a complex interaction of genetic, biological, psychological, and sociocultural factors. Research shows that brain chemistry imbalances involving serotonin and dopamine, combined with genetic predisposition, play significant roles in development. Additionally, psychological factors like perfectionism, low self-esteem, trauma, and societal pressure about body image and weight contribute to these conditions. Family history of eating disorders or mental health conditions, along with dieting culture and social media influence, can trigger the onset of anorexia nervosa, bulimia nervosa, or binge eating disorder.

What is the best test for eating disorders?

The Sex Hormone Binding Globulin (SHBG) test is the most important blood test for eating disorders because it detects how malnutrition affects your hormonal balance and reproductive health. Both anorexia nervosa and bulimia are associated with elevated SHBG levels, which indicates the body is responding to nutritional deficiencies and severe weight loss. This test helps your healthcare provider monitor the physical complications of eating disorders and track how treatment is improving your hormonal function. While no blood test can diagnose an eating disorder itself, SHBG testing is essential for assessing the medical severity and guiding treatment plans that address both psychological and physical health needs.

When should I get tested for eating disorders?

You should get tested if you or a loved one exhibits restrictive eating patterns, frequent purging behaviors, excessive exercise despite fatigue, or noticeable weight changes. Additionally, consider testing if you experience missed menstrual periods, dizziness or fainting, extreme fatigue, hair loss, or obsessive thoughts about food, weight, and body image. Blood testing is particularly important when someone is in treatment for an eating disorder to monitor nutritional status and organ function, or when physical symptoms suggest that malnutrition is affecting hormone levels and overall health.

What are the symptoms of eating disorders?
Symptoms of eating disorders include both physical and behavioral signs. Physical symptoms include dramatic weight loss or fluctuations, fatigue, dizziness, cold intolerance, hair thinning, brittle nails, irregular or absent menstrual periods, and digestive problems. Behavioral signs include obsessive calorie counting, refusing to eat in public, frequent bathroom trips after meals, excessive exercise, hoarding or hiding food, and wearing baggy clothes to hide body shape. Emotional symptoms include intense fear of gaining weight, distorted body image, mood swings, social withdrawal, and preoccupation with food, dieting, and appearance.
Who is at risk for eating disorders?
People at highest risk for eating disorders include adolescents and young adults, particularly females, though males are increasingly affected. Athletes in sports emphasizing weight or appearance like gymnastics, ballet, wrestling, and running face elevated risk. Individuals with family history of eating disorders or mental health conditions, those with perfectionist or obsessive-compulsive personality traits, and people who have experienced trauma or abuse are more vulnerable. Additionally, people with type 1 diabetes, those in weight-focused professions like modeling or acting, and individuals exposed to diet culture or social media pressure about body image are at increased risk.
What happens if eating disorders are left untreated?
Untreated eating disorders can lead to life-threatening medical complications affecting every organ system. Cardiovascular complications include irregular heartbeat, low blood pressure, heart failure, and sudden cardiac death. Bone loss and osteoporosis can become permanent, increasing fracture risk throughout life. Severe malnutrition causes kidney failure, liver damage, gastrointestinal problems, and electrolyte imbalances that can be fatal. Reproductive health suffers with infertility and pregnancy complications. Additionally, untreated eating disorders have the highest mortality rate of any mental health condition, with death resulting from medical complications, suicide, or substance abuse. Early intervention and comprehensive treatment are critical for recovery and preventing permanent damage.
Can eating disorders be diagnosed with a blood test?
Eating disorders cannot be diagnosed with a blood test alone, as they are mental health conditions diagnosed through clinical evaluation, psychological assessment, and behavioral patterns. However, blood tests are vital for assessing the physical complications and medical severity of eating disorders. Tests like SHBG, complete blood count, comprehensive metabolic panel, electrolytes, thyroid function, and vitamin levels help identify malnutrition effects, hormonal imbalances, organ dysfunction, and life-threatening complications. Blood testing guides medical treatment, monitors recovery progress, and helps healthcare providers address the physical damage caused by restrictive eating, purging, or binge eating behaviors.
How are eating disorders treated?
Eating disorders require comprehensive treatment involving a multidisciplinary team including mental health professionals, physicians, and registered dietitians. Treatment typically combines psychotherapy such as cognitive-behavioral therapy (CBT), dialectical behavior therapy (DBT), or family-based therapy with nutritional counseling to restore healthy eating patterns and normalize weight. Medical monitoring addresses physical complications and may include medications for co-occurring conditions like depression or anxiety. Severe cases may require hospitalization or residential treatment programs for medical stabilization and intensive therapy. Recovery is possible with appropriate treatment, though it often requires long-term support and relapse prevention strategies.
How can I prevent eating disorders?
Prevention of eating disorders involves promoting healthy relationships with food and body image from an early age. Focus on health and wellbeing rather than weight or appearance, avoid diet talk and body criticism, and encourage intuitive eating that honors hunger and fullness cues. Build self-esteem based on character and abilities rather than looks, limit exposure to unrealistic media images, and cultivate critical thinking about diet culture. Teach stress management and coping skills, maintain regular family meals without pressure or judgment, and seek early intervention if concerning eating behaviors emerge. Creating a supportive environment that values diversity in body shapes and sizes is essential for prevention.
What natural remedies help with eating disorders?
While eating disorders require professional medical and psychological treatment, certain supportive practices can complement professional care. Mindfulness and meditation help reduce anxiety around food and body image, while gentle yoga or movement practices can rebuild a positive relationship with your body without excessive exercise. Adequate sleep supports hormone regulation and emotional stability. Omega-3 fatty acids from fish or supplements may support brain health and mood. Journaling helps process emotions and identify triggers. Support groups provide community and reduce isolation. However, these natural approaches should never replace professional treatment, as eating disorders are serious medical conditions requiring expert intervention, nutritional rehabilitation, and ongoing psychological support for full recovery.

What this means

Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
