The Surprising Differences & Similarities Of Eating Disorders

Diagnosing An Eating Disorder

To diagnose an individual with either anorexia or bulimia, up to several tests and continuous observation and examination may occur to accurately diagnose the type of eating disorder and the severity of it. Tests include a physical exam, lab tests, a psychological evaluation, and other studies. A physical exam can include measuring the patient’s height and weight, checking their vital signs such as their heart rate, blood pressure, and temperature, analyzing the skin and nails for any noticeable issues, listening to the heart and lungs, and examining the abdomen region. Lab tests can include a complete blood count (CBC) and more in-depth, specialized blood tests to check the patient’s electrolytes and protein levels, as well as to analyze how the liver, kidney, and thyroid are functioning.

A psychological evaluation typically includes a doctor or mental health professional asking the individual about their thoughts, feelings, and eating habits. A complete psychological self-assessment may also be done. Other studies can include an x-ray to check the patient’s bone density, stress fractures, or broken bones, and to also look for heart problems or if pneumonia is present. An electrocardiogram can be performed to also check for heart irregularities. A mental health professional can also use the diagnostic criteria for anorexia and bulimia in the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association.
