                                While drinking enough water is crucial for health, it is possible to have too much of a good thing. The medical term for excessive thirst or compulsive water drinking is polydipsia, which is a symptom rather than a disease in itself. A person who drinks too much water may be called polydipsic, and in some cases, may be dealing with a psychological condition known as psychogenic polydipsia.
