Frequently Asked Questions
Expert answers from our medical team
What are early signs of kidney trouble?
Early kidney disease is silent — no symptoms until 60-70% of function is lost. That's why blood tests (creatinine, eGFR) and urine tests (for protein) matter. Later signs: swelling in feet or around eyes, foamy urine, changes in urination frequency, fatigue, itchy skin, poor appetite, or high BP that's hard to control. If you have diabetes or hypertension, annual kidney checks are essential.
How does diabetes affect my kidneys?
Long-term high blood sugar damages the tiny filters in the kidneys. Over years, this leads to protein leaking into urine, then falling kidney function, and in some cases eventual dialysis or transplant. The good news: tight blood sugar control, BP control, and specific medications (ACE inhibitors, ARBs, SGLT2 inhibitors) dramatically slow this. Annual urine microalbumin test catches early damage when it's still reversible.
Should I worry about protein in my urine?
Yes — persistent protein in urine (proteinuria or albuminuria) is one of the earliest signs of kidney damage, especially in diabetes and hypertension. A single positive result should be repeated to confirm. If confirmed, treatment usually includes a specific class of BP medications that also protect kidneys, even if BP isn't very high. Don't ignore it.
What foods harm the kidneys?
For healthy kidneys, no specific food is harmful in normal amounts. For someone with reduced kidney function, doctors often advise limiting salt, potassium (in some cases), phosphorus, and protein — but the specifics depend on your kidney stage. Over-the-counter painkillers (especially NSAIDs like ibuprofen and diclofenac) can harm kidneys, particularly with regular use — safer to check with your doctor before frequent use.
Can kidney disease be reversed?
Early damage — the leaking of small amounts of protein — can often be reversed or halted with good BP and sugar control. Once significant scarring has happened (chronic kidney disease stage 3-5), the goal shifts to slowing progression rather than reversing damage. This is why early screening in diabetes and hypertension matters so much.
