Clear urine is most commonly due to drinking an excessive amount of water, which dilutes the yellow pigments normally present in urine, making it appear colorless or very pale. This is usually a sign of good hydration. However, consistently clear urine can also indicate overhydration, which may dilute essential salts and electrolytes in the body. In some cases, clear urine might be related to medical conditions such as diabetes mellitus or diabetes insipidus, where the body produces excessive urine. Certain medications like diuretics can also result in clear urine by promoting increased urination. If clear urine happens frequently along with excessive thirst or other symptoms, consulting a healthcare professional is advisable to rule out underlying issues.
