Dipsosis is the excessive thirst; overwhelming desire for water or another liquid. Dipsosis may occur when the amount of water in the body falls below normal. Any activity that causes perspiration can deplete the body's water supply and trigger dipsosis. So can fever, anxiety, sunburn and heat exhaustion. Other causes of water loss and dipsosis include the following: Diabetes, vomiting and diarrhea, diuretic drinks, diuretic medicines, taking in too much salt.

A diuretic is any substance that promotes diuresis, the increased production of urine. This includes forced diuresis. A diuretic tablet is sometimes colloquially called a water tablet. There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys.
