Adipsia; Lack of thirst; Absence of thirst
Absence of thirst is a lack of the urge to drink fluids, even when the body is low on water or has an excess amount of salt.
Not being thirsty at various times during the day is normal, if the body does not need fluid replacement. However, a quick change in the need for fluids should prompt a visit to your doctor.
