What causes 6-yearold to drink lot of water?
Patient: Hi there. I have a question about my baby cousin (6 year old boy) who apparently has got a rare sickness and he drinks a lot of water throughout the day (3-4 litres) I don't know any other symptoms because they won't say. What sickness (rare) could this be and how serious? Doctor: Hi...This could be an initial symptom of diabetes insipidus. This is called polydypsia in medical terms. I suggest you get him evaluated with his pediatrician. The other possibility is a renal tubular disorder.Regards - Dr. Sumanth
