o reveal the weight loss determination is carried out Somatometric indicators.These include: the dynamics of weight loss, body mass index by Quetelet (body weight, kg / height m ²), arm circumference (in the region of the middle third of the arm broken arm).
| Data | Rate | Malnutrition easy | Malnutrition of moderate | Malnutrition heavy |
| Loss of body weight (% of initial) | 0-2 | 2-5 | 5-10 | > 10 |
| Body mass index (kg / m ²) | 26-19 | 19-17,5 | 17.5-15.5 | <15.5 |
| Arm circumference (cm) male female |
29-26
23-20 |
28.25
22,5-19,5 |
26-23
<20 |
25-22,5
<19.5 |
With the help of laboratory parameters determine the severity of weight loss possible causes. In the overall analysis of the blood revealed inflammation, anemia. In the analysis of blood glucose define diabetes. Hormone levels of TSH (thyroid stimulating hormone), T3 and T4 (thyroid hormone) - to explore the evaluation of thyroid function. Biochemical blood: liver function tests (to evaluate the function of the liver), creatinine (kidney failure detection), elektorolity.Proteinogramma and acute phase proteins - examined to assess the degree of protein deficiency and determination of the inflammatory process. Revmoproby - to detect diseases of the connective tissue, immune deficiency states. Fecal helminth eggs. According to the testimony of specific antibodies to determine the causative agents of infectious diseases, HIV infection, tumor markers, markers of TB. Carry out research of the gastrointestinal tract: fibroezofagogastroduodenoscopy, colonoscopy, ultrasound of the abdomen. Chest X-ray - to detect inflammation, tuberculosis, cancer pathology.
In identifying the relevant pathology requires specialist advice: infectious disease, rheumatology, TB specialist, oncologist, endocrinologist, gastroenterologist.
With the exclusion of organic disease, and the diagnosis is confirmed, "neurogenic anorexia", requires the review of a psychiatrist.
