If you have an unquenchable thirst, what illness could it be? (Apart from diabetes)?
Unquenchable thirst, also called polydipsia, occurs when the patient is dehydrated, or when the thirst mechanism is deranged, ie "psychogenic polydipsia" which is a psychiatric illness.
Dehydration can occur from water deprivation, or from excessive water loss.
Water loss is mainly urinary.
There are two main reasons why the body would produce huge amounts of urine:
1. Diabetes insipidus - this is NOT what people mean when they say "Diabetes". That disease is diabetes mellitus. Diabetes insipidus is when the body is unable to form concentrated urine (either through lack of secretion of anti-diuretic hormone, or lack of efficacy of it as may occur when taking lithium), leading to large volumes of water loss.
2. Excessive amount of a solute which the body is getting rid of, eg, glucose in the case of uncontrolled diabetes mellitus. In this case the kidneys just flush lots of fluid through.
But water loss can also occur from the gastro-intestinal tract, ie vomiting and diarrhoea.
Excessive sweating will also cause thirst.
Ask a doctor, or go to webmd.com
askign a bunch of people like us, could lead you down a path you don't want to go, and it could be something serious.
