Anorexia Nervosa Diagnosis in Adults
In Anorexia Nervosa Diagnosis, the physician first asks first about the patient’s diet and weight, such as how much he or she is worried about his weight and whether he often regurgitates the food he has consumed.
After that the doctor will also collect data about the patient’s weight, especially if the patient is experiencing significant weight loss.
To determine a healthy weight, the doctor will calculate body mass index (BMI) or body mass index (BMI). BMI is a weight calculation that refers to a person’s weight and height ratio. The benefit of calculating BMI is to see if a person has a healthy overweight, deficiency or weight.
The formula used in calculating BMI is the body weight in kilograms divided by the height of the body in meters squared (m²). For example if the patient weighs 66 kilograms and the height is 1.65 meters, then the calculation is 66 / 1.65 × 1.65 = 24.24 kg / m²
Normal BMI for adults in Asia is 18.5-22.9 (kg / m2), whereas normal BMI for children and adolescents depends on their age. In adults, anorexia may be suspected if BMI is below 17.
To diagnose anorexia nervosa does not require specific laboratory tests. But if doctors suspect drastic weight loss patients are not caused by anorexia but by other diseases, blood tests and X-rays may be done to confirm.
In addition, laboratory tests will also be done to see the existence of organ damage due to weight loss. A person is susceptible to heart problems if they have anorexia, including low blood pressure, arrhythmias, heart valve disease, fluid buildup or edema (on the hands, feet, and face), and heart failure. To ensure this, the doctor will perform blood pressure, pulse, hand and foot examinations, and, electrocardiogram.
Doctors may also ask the patient to perform simple physical movements to see if the muscles’ strength of the patient is disrupted by anorexia. Examples of such physical movement tests are squatting, standing, and shifting when seated.
