Your kidneys work quietly every day. They do filter waste from our blood, remove extra fluid, help balance minerals, and support several other important functions.
The problem is that kidney disease doesn’t always cause obvious symptoms at the beginning. In fact, many people can have early kidney disease without realizing anything is wrong.
That’s why knowing the possible symptoms of kidney disease can be useful. More importantly, people with risk factors such as diabetes or high blood pressure may need regular kidney tests even when they feel perfectly healthy.
Let’s first look at the possible warning symptoms of Kidney Disease.
What Is Kidney Disease?
In my view, kidney disease mostly happens when the kidneys become damaged or don’t work properly.
Whenever kidney function decreases, waste and extra fluid may build up in our body. Chronic kidney disease (CKD) means kidney damage or reduced kidney function that continues for at least three months.
Here, diabetes and high blood pressure are two of the most common causes of CKD. Other kind of risk factors include heart disease, obesity, older age, and a family history of kidney disease.

10 Symptoms of Kidney Disease You Watch For
1. Changes in Your Urination
A change in your usual urination pattern can sometimes be a symptoms of kidney disease.
You may notice:
⦁ Urinating more often, especially at night time
⦁ Urinating less than usual
⦁ Changes in the quantity of urine
⦁ Difficulty in urinating
⦁ An unusual change in your normal pattern
However, most of the time, urinary infections, some prostate problems, medications, and other conditions can also cause these changes.
2. Foamy or Bubbly Urine
Occasional bubbles in your urine are usually not a reason to panic.
But urine that repeatedly looks very foamy may sometimes be linked to excess protein, or albumin, in the urine. A damaged kidney can allow albumin to pass into the urine.
If you keep noticing unusually foamy urine, mention it to your doctor.
3. Swelling in your Feet and Ankles
Your kidneys are very helpful in removing extra salt as well as fluid from your body.
Whenever kidney function is significantly affected, fluid can build up and cause swelling, particularly in the:
⦁ Feet
⦁ Ankles
⦁ Legs
⦁ Hands
⦁ Face
This swelling is called edema. It can be more common when kidney disease is at an advanced stage or when there is significant protein loss through the urine.
4. See Blood in the Urine
Pink, red, or cola-colored urine may sometimes indicate blood in the urine.
This does not automatically mean you have kidney disease. You may have Kidney stones, urinary infections, certain medications, or other problems that can also cause blood in the urine.
Still, if you see visible blood in your urine should be checked by a healthcare professional.
5. Feeling More Tired or Weak
Persistent tiredness can be another symptom of kidney disease, particularly as kidney disease becomes more advanced leval.
You might feel like unusually weak, have less energy, or find it much harder to concentrate on any work.
Of course, tiredness is extremely common and can have many causes. Poor sleep, stress, anemia, infections, thyroid problems, and other health conditions can all play an important role in symptoms of kidney disease.
6. Your Puffy Eyes
Some people have symptoms of kidney disease notice puffiness around their eyes, especially in the morning.
This can mostly happen when the body retains fluid or when protein is leaking into the urine.
But puffy eyes are not specific to kidney disease. Here, your lack of sleep, allergies, and other conditions can cause them too.
7. Loss of Appetite, Nausea, or Vomiting Problem
When your kidney disease becomes more advanced, waste products can build up in the blood.
This may lead to:
⦁ Poor appetite
⦁ Nausea
⦁ Vomiting
⦁ An unpleasant or metallic taste
⦁ Unintentional weight loss
These symptoms of kidney disease are more concerning when they occur along with other signs of reduced kidney function.
8. Dry Skin or Itching
If you have persistent itching and unusually dry skin can occur in high-level symptoms of kidney disease.
Here, Changes in mineral as well as waste levels in the body may contribute to these symptoms.
But you don’t assume that itchy skin means your kidneys are failing. Here, Dry weather, allergies, eczema, medications, and many other conditions can cause itching.
9. You Face the Problem Of Muscle Cramps
Some people with advanced kidney disease experience muscle cramps.
Changes in your fluid and mineral balance may contribute to cramps or muscle weakness.
Frequent or severe cramps can also have other causes, so they need to be considered in context rather than treated as a kidney-specific type of symptom.
10. You May Face Sleep and Concentration Problems
Your symptoms of kidney disease can sometimes affect sleep and concentration, particularly when in more advanced stages.
You may notice things like this:
⦁ Difficulty sleeping
⦁ Restless sleep
⦁ You face problems with your concentration level
⦁ You feel mentally foggy type
These symptoms aren’t specific to kidney disease, but they are worth discussing with a healthcare professional if they persist.
What Are the Early Symptoms of Kidney Disease?
Here’s the part many people don’t realize very well:
Early kidney disease may cause no symptoms at all.
You might feel completely normal while kidney damage is developing.
That’s why blood and urine tests are so important for people at higher risk with symptoms of kidney disease. NIDDK identifies diabetes, high blood pressure, heart disease, and a family history of kidney failure as important reasons to discuss kidney testing with a healthcare professional.
In other words, we can say that waiting for symptoms isn’t always the best way to find kidney disease.

How Is Kidney Disease Diagnosed?
Symptoms alone cannot confirm kidney disease.
Doctors commonly use two important types of tests.
Blood Test for Kidney Function
A blood test measures creatinine and can be used to calculate your estimated glomerular filtration rate, commonly called eGFR.
eGFR provides an estimate of how well your kidneys filter your blood.
Urine Test
A urine test can look for albumin, a protein that normally stays in the blood.
One commonly used test is the urine albumin-to-creatinine ratio (UACR). A UACR above 30 mg/g may be a sign of kidney disease, although your healthcare professional may repeat testing before making a diagnosis.
Your doctor may also recommend other tests based on your symptoms of kidney disease and medical history.

Who Is at Higher Risk of Kidney Disease?
Sometimes, some people need to pay more attention to their kidney health.
Here, Risk factors include:
⦁ If you have diabetes
⦁ High blood pressure
⦁ Any kind of heart disease
⦁ Obesity
⦁ Being older than 60
⦁ Any family history of kidney disease or kidney failure
⦁ Any previous episode of acute kidney injury
Here, diabetes and high blood pressure are particularly important because they are major causes of chronic symptoms of kidney disease.
When Should You Go to the Doctor?
You don’t want to ignore persistent or unexplained changes like swelling, foamy urine, blood in the urine, significant changes in urination, ongoing fatigue, or unexplained nausea.
And my suggestion is that if you have diabetes or high blood pressure, don’t wait for symptoms before asking about kidney testing.
You need to seek urgent medical care if you have severe symptoms such as very little or no urine, severe shortness of breath, significant swelling, confusion, or a sudden major change in your health.
Final Thoughts
The biggest thing to remember about symptoms of kidney disease is that symptoms may not appear in the early stage.
So don’t rely only on how you feel.
If you have diabetes, high blood pressure, heart disease, or a family history of kidney problems, talk with your healthcare professional about appropriate kidney testing.
Early detection can give you more time to address the problem and protect kidney function very well.
And if you’ve noticed persistent changes in your urine, swelling, unexplained tiredness, or other unusual symptoms, don’t simply ignore them.
A simple conversation with your doctor and the right blood and urine tests can tell you much more than symptoms alone.

Yes. This is one of the most important facts about chronic kidney disease. Early CKD often has few or no symptoms, so testing can be very important for people at higher risk.
