What Affects It

Urine color can become darker when you are dehydrated, and certain foods or medicines can change its smell or color. Small day-to-day variation is normal, but persistent redness, cloudy urine, strong foul odor, pain, or burning can signal a problem and should be checked by a clinician.

When to Get Help

If urine is consistently red, tea-colored, very cloudy, unusually foamy, or painful to pass, it is worth medical evaluation. If you want, I can also give you a one-line version or a symptom guide for abnormal urine.
