From the Guidelines
Clear urine typically indicates that you are well-hydrated, but it can also be a sign of certain medical conditions, such as diabetes insipidus, which affects the body's ability to regulate water, as noted in a recent study 1. When you drink plenty of fluids, especially water, your urine becomes diluted, resulting in a clear or pale yellow color. This is generally a sign of good hydration status and is considered healthy. However, consistently clear urine could sometimes indicate overhydration, where you're drinking more water than your kidneys can process efficiently. In rare cases, clear urine might be associated with certain medical conditions like diabetes insipidus, which affects the body's ability to regulate water, or the use of diuretic medications that increase urine production, as discussed in another study 2. If your urine is consistently clear despite not drinking excessive amounts of water, or if you experience other symptoms like increased thirst, frequent urination, or fatigue, it would be advisable to consult with a healthcare provider. They can evaluate whether your clear urine is simply due to good hydration or if it might indicate an underlying health issue that requires attention, and provide guidance on the best course of action, as recommended by the National Kidney Foundation 3, 4.
Some key points to consider when evaluating clear urine include:
- The color and consistency of the urine
- The frequency and volume of urination
- Any underlying medical conditions, such as diabetes insipidus or kidney disease
- The use of diuretic medications or other substances that may affect urine production
- Any other symptoms, such as increased thirst, fatigue, or pain while urinating.
It's essential to consult with a healthcare provider if you have concerns about your urine or overall health, as they can provide personalized guidance and recommendations based on your individual needs and circumstances.

From the Research
Possible Causes of Clear Urine
- Clear urine can be a sign of several conditions, including: + Overhydration: drinking too much water can lead to clear urine 5, 6 + Diabetes insipidus: a condition characterized by the excretion of large volumes of dilute urine 6, 7 + Nephrogenic diabetes insipidus: a condition where the kidneys are unable to concentrate urine due to insensitivity to antidiuretic hormone 5, 7
- Other possible causes of clear urine include: + Certain medications, such as lithium or ifosfamide 5, 7 + Metabolic disturbances, such as hypokalemia or hypercalcemia 5 + Kidney damage or disease 5, 7
Characteristics of Clear Urine
- Clear urine is often characterized by: + Low osmolality: a measure of the concentration of solutes in the urine 5, 6 + High volume: clear urine can be a sign of polyuria, or excessive urine production 6, 7
- In some cases, clear urine may be a sign of an underlying condition that requires medical attention 5, 6, 7
Diagnosis and Treatment
- Diagnosis of the underlying cause of clear urine typically involves: + Urine tests: to measure osmolality and other characteristics of the urine 5, 6 + Blood tests: to check for underlying conditions such as diabetes insipidus or kidney disease 5, 6 + Imaging studies: to visualize the kidneys and urinary tract 5, 7
- Treatment of clear urine depends on the underlying cause, but may include: + Medications: such as desmopressin to regulate urine production 8, 9 + Lifestyle changes: such as reducing fluid intake or managing underlying conditions 5, 6
