飲水量が1日15リットルに及ぶ高度の心因性煩渇多飲症(Psychogenic polydipsia)の一治療経験 : 目盛付き容器使用による飲水量制限治療の試み

抄録

A 24-yearold male was admitted to our hospital with his complaints of severe polydipsia, polyuria and headache. The total volume of urine reached up to nearly 15 liters per day. He showed nausea, vomiting, aggravation of headache and polydipsia by psychic stress during his hospitalization. No remarkable organic changes were observed in the laboratory data and other examinations. Being given a water deprivation test, he was diagnosed as psychogenic polydipsia. Psychological and environmental factors were considered to be related to the development of the disorder. He received supportive psychotherapy as well as drug treatment with no marked improvement. When the intake of water was restricted to the volume of 2 liters per day by using a scaled polyethylene vessel, the patient made a rapid recovery.
