Have you noticed changes in your urine, swelling around your ankles, unusual tiredness or a change in how often you use the bathroom? These symptoms can have many causes but some may be linked to kidney problems. Knowing the early signs of kidney problems can help you recognize when it may be worth speaking with a kidney doctor.
There is one important point to understand: early kidney disease does not always cause noticeable symptoms. Many people with chronic kidney disease (CKD) may not realize they have it until kidney function declines. Recognizing the early symptoms of kidney disease can help you notice changes that may need attention.
Quick Insight: What are the Early Signs of Kidney Problems?
The early signs of kidney problems may include changes in urination, foamy urine, swelling, fatigue, high blood pressure and itching. However, symptoms can vary and early CKD may cause no noticeable signs. Blood and urine tests are the best way to check kidney function.
11 Early Signs of Kidney Problems
The early signs of kidney problems can vary from changes in urination and swelling to fatigue, blood pressure changes and other kidney disease symptoms.
1. Changes in Urination
Changes in how often you urinate or how much urine you produce may be among the early symptoms of kidney problems.
- Urinating more often, especially at night
- Producing less urine than usual
- Noticeable or persistent changes in urination
2. Foamy or Bubbly Urine
Repeatedly foamy or bubbly urine may sometimes indicate protein in urine, which can occur when the kidney’s filtering system is damaged.
- Persistent or unusually foamy urine
- Proteinuria or albuminuria
- May be evaluated with a urine test, such as a UACR
3. Blood in the Urine
Blood in the urine, known as hematuria, can be a possible sign of kidney problems and should not be ignored.
- Pink, red or brown-colored urine
- Blood detected during urine testing
- Persistent or unexplained blood in urine
4. Swelling in the Legs, Ankles or Feet
Swelling or edema, can occur when the kidneys have difficulty removing excess fluid and salt from the body.
- Swelling around the ankles or feet
- Swelling that extends into the legs
- Sometimes swelling in the hands or face
5. Puffiness Around the Eyes
Puffiness around the eyes, especially in the morning, may occur with fluid retention or protein loss through the urine and can sometimes appear with other kidney health symptoms.
- Swelling or puffiness around the eyes
- More noticeable in the morning
- May occur with leg swelling or foamy urine
6. Persistent Fatigue or Low Energy
Persistent tiredness or low energy can occur with kidney disease, particularly when kidney function becomes more impaired.
- Feeling unusually tired
- Reduced energy during everyday activities
- Fatigue occurring with other health changes
7. High Blood Pressure
High blood pressure is closely linked with kidney health and can both contribute to and result from kidney disease.
- Repeatedly high blood pressure readings
- Difficulty controlling blood pressure
- Higher risk when combined with diabetes or other risk factors
8. Itchy or Dry Skin
Itchy or dry skin can occur with kidney disease, particularly when kidney function becomes significantly impaired.
- Persistent or widespread itching
- Dry or irritated skin
- Itching occurring with other health changes
9. Nausea or Loss of Appetite
Nausea and reduced appetite can occur when kidney function becomes significantly impaired and waste products build up in the blood.
- Feeling nauseated
- Reduced interest in food
- Changes in appetite or eating habits
10. Trouble Sleeping or Concentrating
Sleep problems and difficulty concentrating may occur in people with chronic kidney disease, particularly as the condition becomes more advanced.
- Trouble falling or staying asleep
- Difficulty concentrating
- Feeling mentally tired or less alert
11. Muscle Cramps
Muscle cramps may occur when kidney disease affects the body’s fluid and mineral balance, especially as kidney function becomes more impaired.
- Frequent or unexplained cramps
- Cramping in the legs or other muscles
- Cramps occurring with weakness or other symptoms
These signs of kidney disease can have many causes, so persistent or unusual changes should not be ignored and are worth discussing with a doctor.

Can Kidney Problems Have No Symptoms?
Yes. Early kidney disease can develop without noticeable symptoms, especially during the early stages of CKD. This means you may have few or no symptoms of poor kidney function even while kidney damage is developing.
According to the CDC, more than 1 in 7 U.S. adults has CKD and as many as 9 in 10 people with the condition do not know they have it. This is why symptoms alone cannot always identify signs of kidney disease and appropriate testing is important for people at higher risk.
People with diabetes, high blood pressure, heart disease or a family history of kidney failure may have a higher risk of CKD. If you have risk factors or notice persistent changes, speak with a doctor about your kidney health and whether testing may be appropriate.

How Do You Know If Your Kidneys are Working Properly?
Symptoms alone cannot show how well your kidneys are working. Symptoms of poor kidney function may not always be noticeable, so kidney function tests provide a clearer picture.
Common tests include:
- Creatinine: Measures kidney function through a blood test.
- eGFR: Estimates how well your kidneys filter blood.
- Urine albumin: Checks for protein linked to kidney damage.
- UACR: Measures albumin in relation to urine creatinine.
- Blood pressure: Helps assess an important kidney disease risk.
NIDDK recommends eGFR and urine albumin testing for detecting and monitoring CKD. If results are abnormal or you have risk factors, talk with your kidney doctor about whether further testing is needed.
Facts About the Early Signs of Kidney Problems
Knowing these facts can help you understand when kidney changes may need attention.
#1 Early CKD may have no symptoms.
#2 Diabetes can damage the kidneys.
#3 High blood pressure can affect kidney function.
#4 Foamy urine may indicate protein in urine.
#5 Blood in urine should be evaluated.
#6 eGFR and urine tests help assess kidney function.
#7 Early detection can help protect kidney health.
Recognizing the early signs of kidney problems can help you take timely action and discuss concerns with a kidney doctor.
What Can Cause Damage to Your Kidneys?
There is no single cause of every kidney problem. Understanding what can damage your kidneys can help you recognize early signs of a kidney problem and discuss your risk with a doctor.
- Diabetes
- High blood pressure
- Heart disease
- Family history of kidney disease or kidney failure
- Obesity
- Inherited kidney conditions
- Autoimmune diseases
- Previous kidney injury
- Kidney infections or structural problems
- Certain medications or kidney-damaging substances
Knowing your risk factors can help you and your kidney doctor decide if regular kidney function testing is appropriate.
Are Kidney Disease Symptoms Different in Men and Women?
The early signs of kidney problems in women are generally similar to those seen in men. Changes in urination, foamy urine, swelling, fatigue and high blood pressure can occur in both.
Some health conditions can affect kidney disease risk differently. In women, pregnancy-related conditions and certain autoimmune diseases may increase risk, while diabetes and high blood pressure are important risk factors for both men and women.
If you are looking for early signs of kidney disease in females or researching kidney disease symptoms males, focus on persistent changes, individual risk factors and appropriate kidney testing rather than expecting completely different symptoms.
How Can You Protect Your Kidney Health?
Managing risk factors and healthy daily habits can help protect your kidneys and lower the risk associated with the early signs of kidney problems.
Helpful steps include:
- Keep your blood pressure under control.
- Manage diabetes if you have it.
- Follow your doctor’s treatment plan.
- Complete recommended blood and urine tests.
- Maintain a healthy weight and stay active.
- Choose a balanced, kidney-friendly diet.
- Seek care for persistent urinary changes or swelling.
- Check with your doctor before regularly taking medicines or supplements.
NIDDK recommends managing conditions such as diabetes and high blood pressure and getting kidney tests when appropriate. Early kidney disease may not cause noticeable symptoms.

FAQs – 11 Early Signs of Kidney Problems That May Need Attention
Q1. What are the first signs of a kidney issue?
Ans. Possible signs of kidney problems include changes in urination, persistent foamy urine, blood in the urine, swelling, fatigue and high blood pressure. However, early CKD often has no noticeable symptoms, so testing may be needed to identify it.
Q2. What are the 3 early warning signs of kidney disease?
Ans. There is no universal set of three warning signs. However, changes in urination, persistent foamy urine and swelling can be possible signs of kidney problems. Early kidney disease may also have no noticeable symptoms, so testing is important when risk factors are present.
Q3. What are the first signs that your kidneys are struggling?
Ans. Possible early symptoms of kidney disease include persistent changes in urination, protein in the urine, swelling, fatigue or blood in the urine. These symptoms can have other causes, so blood and urine tests are needed to assess kidney function.
Q4. What are the 7 warning signs of kidney failure?
Ans. Symptoms of advanced kidney failure can include major changes in urination, swelling, fatigue, nausea, loss of appetite, itching and difficulty concentrating. Kidney failure is different from early kidney disease and requires medical evaluation.
Q5. What does your face look like with kidney disease?
Ans. Kidney disease can sometimes cause puffiness around the eyes or facial swelling because of fluid retention. However, facial puffiness has many possible causes and does not by itself indicate kidney disease.
