text: <unk>  is the craving for liquids, resulting in the basic instinct of humans or animals to drink. It is an essential mechanism involved in fluid balance. It arises from a lack of fluids and/or an increase in the concentration of certain osmolytes such as salt. If the water volume of the body falls below a certain threshold, or the osmolite concentration becomes too high, the brain signals<unk> .
  Continuous dehydration can cause a myriad of problems, but is most often associated with neurological problems such as seizures, and renal problems.
  Excessive<unk> , known as polydipsia, along with excessive urination, known as polyuria, may be an indication of diabetes.
  There are receptors and other systems in the body that detect a decreased volume or an increased osmolite concentration. They signal to the central nervous system, where central processing succeeds. Some sources therefore distinguish  "Extracellular<unk> " from "intracellular<unk> ", where extracellular<unk>  is<unk>  generated by decreased volume and intracellular<unk>  is<unk>  generated by increased osmolite concentration. Nevertheless, the craving itself is something generated from central processing in the brain, no matter how it is detected.
