Anorexia can be understood on three levels: behavioral, psychosomatic and physiological. First, on the behavioral level, it is manifested by the patient’s own consciousness to cause a continuous and significant caloric intake deficit. Second, the psychosomatic level, mainly manifested as the endless pursuit of thinness, or the morbid fear of obesity, so the patient will fearfully refuse to maintain a normal weight. Third, on the physical level, it is manifested by the emergence of secondary significant physical problems. So for the anorexic patient, weight and body image are important, if not the only source of self-esteem, so a great deal of the day is taken up with related thoughts, accompanied by changes in mood and behavior, which recognizes anorexia as a whole.
