World Kidney Day 2025: What your urine can reveal about your kidney health? Doctor explains | Health

In an interview with HT Lifestyle, Dr. Avinash Srivastava, senior director – urology and kidney transplant, Livasa Hospitals said, “Your urine can impart important information about the state of your kidneys. Because the kidneys filter waste and excess fluids from your blood, anything abnormal in your urine can signal potential problems. Identifying these signs allows you to take early action to prevent kidney damage.”

Dr. Avinash Srivastava further explained what urine colour, odour and frequency can reveal about kidney health.

Urine Color:

Light yellow, yellow: This is normal, and a sign of good hydration.

Dark yellow or amber: You may be dehydrated. This can be aided by drinking additional water.

Brown or cola-coloured: This can also suggest liver problems or severe dehydration but is also one sign in certain cases of kidney disease.

Red or pink: Blood in the urine (hematuria) can indicate bladder or kidney stones, infection, or potentially more serious conditions such as glomerulonephritis.

Urine odour:

An especially strong ammonia smell could indicate dehydration or a urinary tract infection (UTI). Either a sweet or fruity odor may indicate diabetes or high blood sugar. Also read | World Kidney Day 2025: If you have kidney stones, you should avoid carbonated drinks; here’s why

Urine clarity:

Clear urine: Good hydration.

Cloudy or foamy: This can be a sign of excess protein, and can be a sign of possible kidney dysfunction.

Frequent urination, especially at night, can be a sign of early kidney problems or inadequate control of diabetes. Lower urine output indicates possible blockages, damage to the kidneys, or dehydration.

Presence of pain or discomfort:

A burning sensation, the pain of urinating or pain in the lower back may all be indications of kidney stones, infection or inflammation.
