Most people have two kidneys. However, scientifically, even one healthy kidney is enough to maintain normal body function. In simple words, you can live a normal life with just one working kidney.

Kidneys are located at the back of the abdomen, on either side of the spine, just below the rib cage. In simple terms, they sit in your lower back area.

Kidneys remove metabolic waste like urea (from protein breakdown), creatinine (from muscle activity), and toxins. Simply put, they remove harmful substances that your body does not need.

Kidneys regulate fluid balance by adjusting how much water is excreted in urine. Scientifically, they respond to hormones like ADH (antidiuretic hormone). In simple terms, they decide how much water your body should keep or remove.

Dialysis is needed when the kidneys are no longer able to remove waste and excess fluids properly. It is usually recommended in advanced kidney disease based on medical evaluation.

There are two main types: Hemodialysis and Peritoneal Dialysis. Hemodialysis uses a machine to clean the blood, while peritoneal dialysis uses the body’s abdominal lining.

Yes, kidney transplantation is a safe and effective treatment when done by experienced specialists. It helps improve quality of life with proper care and follow-up.

Stay hydrated, eat a balanced diet, control blood pressure and sugar levels, and avoid unnecessary medications. Regular check-ups also help in early detection.

AKI develops rapidly, often within hours to a few days. Unlike chronic kidney disease, it is not a slow process. In simple words, kidney function drops suddenly.

Common causes include dehydration, severe infections (sepsis), low blood pressure, certain medicines, and blockage of urine flow. Simply put, anything that reduces blood flow to kidneys or directly damages them can cause AKI.

Yes. Severe dehydration reduces blood supply to the kidneys, leading to injury. In simple terms, not having enough fluid in the body can harm your kidneys.

Yes, especially severe infections like sepsis. These can reduce blood flow and cause direct kidney damage. Simply put, serious infections can shut down kidney function.

Yes. Painkillers (NSAIDs), some antibiotics, and contrast dyes used in scans can cause AKI. In simple words, unnecessary or excessive medicines can harm your kidneys.

Urine output may decrease significantly or even stop (called oliguria or anuria). However, in some cases, urine may appear normal. Simply put, reduced urine is a warning sign.

Symptoms may include reduced urine, swelling in legs or face, fatigue, nausea, confusion, and shortness of breath. In simple terms, the body starts retaining fluid and toxins.

Yes. Early AKI may not cause noticeable symptoms and is detected only through blood tests. Simply put, it can be silent in the beginning.

People with diabetes, high blood pressure, elderly individuals, hospitalized patients, and those with pre-existing kidney disease are at higher risk. Simply put, vulnerable patients need extra care.

Creatinine is a waste product measured in blood to assess kidney function. In AKI, creatinine levels rise. Simply put, higher creatinine means poorer kidney function.

Oliguria means reduced urine output (less than normal). It is an important sign of kidney dysfunction. Simply put, passing less urine than usual is concerning.

Yes. Both can lead to dehydration and reduced blood flow to kidneys. Simply put, fluid loss from the body can damage kidneys.

In many cases, yes—if treated early and the cause is corrected. However, severe or delayed cases can lead to permanent damage. Simply put, early treatment improves recovery.

AKI is diagnosed using blood tests (creatinine), urine tests, and sometimes imaging like ultrasound. Simply put, doctors check your blood and urine.

Yes, in severe cases where kidneys cannot remove waste or excess fluid. Dialysis may be temporary until kidneys recover. Simply put, a machine may help clean the blood.

Severe breathlessness, no urine, confusion, and swelling are serious signs. These require urgent medical attention. Simply put, these are emergency symptoms.

Yes, especially in high-risk patients. This is called contrast-induced kidney injury. Simply put, certain scans can affect kidney function.

Stay well hydrated, avoid unnecessary medicines, control BP and diabetes, and seek early treatment for infections. Simply put, good care and awareness can prevent AKI.

If you notice reduced urine, swelling, vomiting, diarrhea, or weakness—especially if you have risk factors. Simply put, don’t ignore early warning signs.

CKD develops slowly and is usually permanent, while AKI is sudden and often reversible.

Diabetes and high blood pressure are the most common causes. Others include glomerulonephritis, genetic diseases, and long-term drug use.

Yes. High blood sugar damages kidney filters (glomeruli), leading to diabetic nephropathy.

Yes. Long-standing hypertension damages kidney blood vessels.

Often there are no symptoms in early stages.

Swelling, fatigue, loss of appetite, nausea, decreased urine, itching, and breathlessness.

Estimated Glomerular Filtration Rate (eGFR) measures how well kidneys filter blood.

Creatinine is a waste product in blood used to assess kidney function.

CKD cannot usually be cured, but progression can be slowed with proper treatment.

CKD is divided into 5 stages based on eGFR—from mild (Stage 1) to kidney failure (Stage 5).

Yes. If untreated, CKD can progress to end-stage kidney disease requiring dialysis or transplant.

Blood test (creatinine, eGFR) and urine test (protein/albumin).

Protein leakage in urine (albuminuria) is an early sign of kidney damage.

Yes. Long-term use of NSAIDs can damage kidneys.

It causes fluid retention, anemia, bone disease, and electrolyte imbalance.

Depends on stage and doctor advice. Early CKD → normal hydration; advanced CKD → fluid restriction.

Low salt, controlled protein, low potassium/phosphorus (in advanced stages).

Control diabetes and BP, avoid unnecessary drugs, maintain healthy lifestyle.

If you have diabetes, BP, swelling, or abnormal reports.

Dialysis is required when kidneys fail to remove toxins and fluid from the body, usually in advanced kidney disease (Stage 5 CKD) or severe AKI. In simple terms, it is needed when kidneys stop working adequately.

There are two main types: Hemodialysis (blood cleaned by a machine) and Peritoneal Dialysis (using the abdomen lining as a filter). In simple terms, one uses a machine, the other uses your body's lining.

Hemodialysis involves passing blood through a machine (dialyzer) that filters waste and returns clean blood to the body. In simple terms, blood is cleaned outside the body using a machine.

Peritoneal dialysis uses the inner lining of the abdomen (peritoneum) to filter blood using dialysis fluid. In simple terms, fluid inside your abdomen helps remove waste.

Hemodialysis is usually done 2–3 times per week, each session lasting 3–5 hours. Peritoneal dialysis is done daily. In simple terms, machine dialysis is a few times weekly, while home dialysis is daily.
