What Causes Polydipsia?

Polydipsia is the condition of being excessively thirsty and it is usually the result of a health problem. Some causes of polydipsia are easily fixed, but some are chronic. Patients with polydipsia will often drink too much water. This might seem like a good thing; after all, water is one of the healthiest things one can drink. However, drinking too much water can lead to further problems such as hyponatremia, which is a low concentration of sodium in the body. Polydipsia can also be annoying to deal with.
