People with diabetes who develop fruity-smelling breath or urine alongside vomiting, confusion, or deep, rapid breathing should seek emergency medical care because diabetic ketoacidosis may be present.
Do not rely on odor to diagnose a condition. Testing is needed to establish the cause.
13. Urination Frequency: Another Important Clue
Changes in how often you urinate can be just as important as changes in color.
Urinating more frequently may be related to increased fluid intake, caffeine, alcohol, pregnancy, or certain medications.
It can also be associated with medical conditions such as urinary tract infections, diabetes, or an overactive bladder.
People with diabetes may notice that they urinate more often because excess glucose in the blood can cause the kidneys to remove more water.
Other possible symptoms include:
-
Increased thirst.
-
Unexplained weight loss.
-
Fatigue.
-
Blurred vision.
-
Increased hunger.
Frequent urination accompanied by excessive thirst should be discussed with a healthcare professional, particularly if it is new or persistent.
On the other hand, difficulty passing urine or being unable to empty the bladder can indicate urinary retention.
A person who suddenly cannot urinate, particularly with lower abdominal pain or swelling, needs urgent medical care.
14. Why Kidney Problems May Exist Even When Urine Looks Normal
One of the most important facts about urine color is that normal-looking urine does not guarantee healthy kidneys.
Some kidney conditions develop gradually without producing obvious changes in appearance.
A person may have protein or microscopic blood in the urine while the urine still looks completely normal.
Chronic kidney disease can also remain unnoticed in its early stages.
Risk factors include:
-
Diabetes.
-
High blood pressure.
-
Cardiovascular disease.
-
A family history of kidney disease.
-
Previous kidney injury.
-
Certain long-term medication exposures.
People with these risk factors may benefit from routine medical monitoring.
Common tests include:
Urinalysis: Examines urine for blood, protein, glucose, and other substances.
Urine albumin-to-creatinine ratio: Measures small amounts of albumin, a type of protein, in urine. It can help detect early kidney damage.
Blood creatinine test: Measures a waste product in the blood that helps assess kidney function.
Estimated glomerular filtration rate (eGFR): Uses blood test information to estimate how effectively the kidneys filter waste.
These tests provide information that cannot be obtained by looking at urine alone.
15. How to Stay Properly Hydrated
Hydration is one of the most common factors influencing urine color.
However, the amount of fluid a person needs depends on several variables, including body size, physical activity, climate, diet, and health status.
There is no universal water target that is appropriate for everyone.
Some practical habits can help support normal hydration:
Drink regularly throughout the day. Avoid waiting until you feel extremely thirsty, especially during hot weather or physical activity.
Increase fluid intake when appropriate. Sweating, fever, vomiting, and diarrhea can increase fluid losses. Oral rehydration solutions may be useful in certain situations, particularly when significant fluid and electrolyte losses occur.
Include water-rich foods. Fruits and vegetables such as watermelon, cucumber, oranges, and lettuce contribute to daily fluid intake.
Pay attention to heat and exercise. People who work outdoors or exercise for long periods may need additional fluids and, in some circumstances, electrolytes.
Follow medical advice. People with kidney, heart, or liver conditions may need to limit fluids or follow a specific hydration plan.
Avoid drinking very large quantities of water rapidly. More water is not always better.
16. What Happens During a Medical Urine Test?
When urine color changes unexpectedly, a healthcare professional may recommend a urinalysis.
This is a common test that provides information about several aspects of urinary health.
A typical urinalysis may include three parts.
Visual examination
The sample is examined for color, clarity, and general appearance. Unusual cloudiness, visible blood, or other changes may prompt further testing.
Dipstick examination
A special strip is placed into the urine. Chemical indicators can help detect:
-
Blood.
-
Protein.
-
Glucose.
-
Ketones.
-
Nitrites.
-
Leukocyte esterase.
-
Urine concentration.
-
Acidity.
These results can help identify possible infection, kidney problems, diabetes-related abnormalities, or other conditions.
Microscopic examination
A laboratory professional examines the sample under a microscope to look for red blood cells, white blood cells, bacteria, crystals, and other substances.
Depending on the findings, additional tests may be recommended.
For example, a urine culture can help identify bacteria responsible for an infection and determine which antibiotics may be effective.
Blood tests may be used to assess kidney function, liver function, blood glucose, or other relevant measurements.
The important point is that a urine test is often more informative than visual inspection alone.
17. How to Collect a Clean Urine Sample
If a healthcare professional asks for a urine sample, collecting it correctly can improve the reliability of the result.
For many routine urine tests, a clean-catch midstream sample is recommended.
The general process is:
-
Wash your hands.
-
Use the cleaning instructions provided by the clinic or laboratory.
-
Begin urinating into the toilet.
-
After the initial flow, collect some urine in the sterile container without touching the inside.
-
Finish urinating into the toilet.
-
Close the container securely and deliver it according to the laboratory's instructions.
The exact instructions may vary depending on the test.
For some tests, a first-morning sample is preferred. Other tests require timed collection or special preparation.
Always follow the instructions provided by your healthcare professional.
18. Special Considerations for Older Adults
Changes in urinary habits become more common with age.
Older adults may experience changes related to prostate enlargement, bladder function, medication use, diabetes, or kidney conditions.
Some may also have difficulty recognizing or communicating early symptoms.
For example, an older person with a urinary tract infection may experience confusion or a decline in daily functioning. However, confusion alone does not prove that a UTI is present. Dehydration, medication effects, and other illnesses can cause similar changes.
