Eating Disorders
What is Eating disorders?
Eating disorders are serious mental health conditions that involve unhealthy patterns of eating, thinking about food, and body image. They affect how you eat, how you feel about food, and how you see your body. These conditions can cause severe physical and emotional harm if left untreated.
The most common types include anorexia nervosa, which involves restricting food intake and intense fear of weight gain, bulimia nervosa, which involves cycles of binge eating followed by purging, and binge eating disorder, which involves eating large amounts of food without control. Eating disorders affect people of all genders, ages, and backgrounds. They are not a choice or a phase, but real medical conditions that require professional treatment.
These conditions impact more than just weight. They affect hormone balance, bone health, heart function, and nutritional status throughout the body. Blood tests can reveal some of the physical effects of eating disorders, including changes in hormone levels and signs of malnutrition. Early detection and treatment lead to better outcomes and help prevent long-term health complications.
Symptoms
- Extreme restriction of food intake or skipping meals
- Preoccupation with food, calories, weight, or body shape
- Eating in secret or avoiding eating with others
- Rapid weight loss or frequent weight fluctuations
- Intense fear of gaining weight even when underweight
- Excessive exercise even when tired or injured
- Binge eating or feeling out of control around food
- Self-induced vomiting or misuse of laxatives
- Fatigue, dizziness, or fainting
- Hair loss, brittle nails, or dry skin
- Irregular or absent menstrual periods
- Feeling cold all the time
- Social withdrawal and mood changes
Some people with eating disorders hide their symptoms well, and physical signs may not be obvious early on. Mental and emotional symptoms often appear before physical changes become noticeable. Anyone showing these warning signs deserves compassionate support and professional help.

Causes and risk factors
Eating disorders develop from a combination of genetic, biological, psychological, and environmental factors. Research shows that brain chemistry, particularly involving serotonin and dopamine, plays a role in these conditions. Family history of eating disorders or other mental health conditions increases risk. Personality traits like perfectionism, anxiety, and difficulty handling emotions also contribute to development.
Cultural pressure around body image and dieting can trigger eating disorders in vulnerable individuals. Traumatic experiences, major life changes, and chronic stress may also act as triggers. Certain activities and professions that emphasize weight or appearance, such as dance, modeling, or athletics, carry higher risk. People with a history of being bullied about weight or appearance are more vulnerable. Early intervention matters because eating disorders become harder to treat the longer they continue.
How it's diagnosed
Diagnosis involves a thorough evaluation by mental health professionals and medical doctors. This includes discussing eating patterns, thoughts about food and body image, and physical symptoms. A physical exam checks for medical complications. Healthcare providers assess whether behaviors meet specific criteria for anorexia nervosa, bulimia nervosa, binge eating disorder, or other specified feeding and eating disorders.
Blood tests help identify the physical impact of eating disorders on the body. Rite Aid offers testing that measures Sex Hormone Binding Globulin, which can be elevated in eating disorders due to malnutrition. Blood work also checks for electrolyte imbalances, anemia, kidney function, liver function, and hormone levels. These tests help doctors understand how the eating disorder is affecting your body and monitor your health during recovery. Regular testing tracks progress and helps catch medical complications early.

Frequently asked questions
Blood tests cannot diagnose eating disorders directly, but they reveal physical effects on the body. Tests can show hormone imbalances, nutritional deficiencies, and other medical complications. Sex Hormone Binding Globulin levels may be elevated in people with anorexia or bulimia. Blood work helps doctors assess the severity of physical impact and monitor recovery progress.
Sex Hormone Binding Globulin is a protein that carries sex hormones through your bloodstream. Malnutrition from eating disorders causes the body to produce more of this protein. Both anorexia nervosa and bulimia have been linked to higher SHBG levels. Measuring SHBG helps assess how eating patterns are affecting hormone balance.
No, eating disorders are complex mental health conditions, not simple choices about appearance. They involve disordered thoughts about food, control, self-worth, and coping with emotions. Many factors contribute including genetics, brain chemistry, trauma, and environmental stress. Body image concerns are one symptom, but the underlying causes run much deeper.
Yes, eating disorders affect people of all genders, though they are more commonly diagnosed in women. Men and boys may face different pressures around muscle building or athletic performance. Their symptoms are sometimes missed because eating disorders are stereotyped as affecting only women. Anyone can develop an eating disorder regardless of gender identity.

Working with a registered dietitian helps create structured meal plans and rebuild a healthy relationship with food. Proper nutrition supports brain function, which improves mental health symptoms. Nutritional counseling addresses food fears and teaches balanced eating habits.
Yes, regular blood testing during recovery helps monitor your physical health and nutritional status. Tests can identify complications that need treatment and show whether your body is healing.
