What could be the cause of frequent thirst?

Answer by  DrMom (854)

Frequent thirst can be an indication for diabetes but that may not tell the whole story. Frequent and excessive thirst can be a sign of dehydration. It can also signal an adverse reaction to aspartame, an artificial sweetener commonly used in diet drinks. Speak with your doctor about your concerns.

A disease called Sjogren's syndrome which causes inflammation of the moisture producing glands can cause a dry mouth which could also translate into what seems to be thirst; diabetes can also cause excessive thirst; and the easiest answer is eating salty foods or a salty meal.
