Excessive thirst in children should not be ignored because it can be a symptom of a serious illness or an underlying disorder. Some major causes of excessive thirst in children are discussed below.

Diabetes Insipidus

It is a health condition in which the sufferer has frequent urination. This leads to loss of excessive fluids from their body and causes excessive thirst in children. Excessive thirst in children is commonly caused by detrimental blood sugar levels, which may be a warning sign of diabetes.
