The hypothalamus is a brain region that, among other functions, is responsible for maintaining the amount of water necessary for the body. Therefore, it is also responsible for warning of the lack of fluid and emit the thirst signal.

An alteration in the functioning mechanism of the hypothalamus could cause episodes of potomania (neurological potomania). Experts agree that this is quite strange, so they associate the disorder with a psychiatric imbalance.

The factors that can trigger the onset of this disorder are:

  • Emotional disorders, such as anxiety disorders, personality disorder, delusional symptoms and hysterical symptoms.
  • Alterations in the functioning of the hypothalamus, since, as we have said, the hypothalamus is the part of the brain responsible for the perception of thirst.
  • Chronic kidney disease
  • Organic disorders or hormonal pathologies, such as diabetes insipidus, one of whose symptoms is precisely polydipsia or excess thirst.


The human body tries to keep the volume of water constant and the concentration of electrolytes necessary for the functioning of all organs.

Excess water causes the body that essential minerals such as potassium, sodium and magnesium, dilute faster than usual. This causes cramps, fatigue and slowness in the execution of simple cognitive tasks.

If the water intake continues to increase, it is likely to observe massive loss of potassium which will trigger, mainly, in cardiac difficulties.

On the other hand, the kidneys are also organs affected by excessive fluid intake. Taken to the limit, they can cause hyponatremia, characterized by the decrease in sodium levels in the blood, which can cause seizures.

In the event that it occurs due to mental illness, the treatment must be psychotherapy, accompanied, in some cases, by psychotropic medication.

If the disorder appears as a consequence of the use of drugs, these should be replaced by other medications that do not cause this side effect.

Therefore, if you feel a strong desire to drink, and especially if you are not motivated by thirst, heat or physical activity, you should check with your doctor to find the source of the problem and prevent it from going further.
