Early Signs of Kidney Disease You Shouldn’t Ignore

Your kidneys are silent workers, filtering waste, balancing fluids, and supporting blood pressure. But when they start to fail, the warning signs might be easy to miss.

You may not even notice a problem until it’s progressed. And that’s what makes early detection of kidney disease so crucial. In this post, brought to you by Manhattan Primary Care, we’re breaking down common and uncommon symptoms of kidney dysfunction, answering those “People Also Ask” questions, and giving you the tools to spot the red flags early, before they escalate.

What Is Kidney Disease and Why Early Detection Matters

Kidney disease develops gradually, reducing kidney function over time. These vital organs filter waste, balance fluids, and regulate blood pressure. Without treatment, toxins can build up unnoticed—up to 90% of kidney function can be lost without symptoms.

Left unchecked, chronic kidney disease (CKD) can lead to kidney failure. Routine preventive care and health screenings, along with awareness of risks like prediabetes and diabetes and hypertension, are key to early detection.

Most Common Early Signs of Kidney Disease

Kidney problems often sneak up quietly. Here are some of the most common symptoms that can point to something being off:

Changes in Urination

One of the first things people notice:

• Frequent urination, especially at night (called nocturia)
• Foamy or bubbly urine (a sign of protein leakage)
• Dark-colored or bloody urine
• Pain or burning while urinating

These can indicate issues with how your kidneys filter waste.

Fatigue and Low Energy

When your kidneys aren’t filtering properly, toxins build up. This can lead to:

• Feeling tired or weak
• Trouble concentrating
• Shortness of breath with exertion

Swelling (Edema)

Kidneys also help regulate fluids. When they struggle, you might notice:

• Puffy eyes
• Swollen hands or feet
• Bloating in the abdomen or face

Kidney Pain

Though not always present, some people experience kidney pain, a dull ache or sharp discomfort in the lower back or sides.

What Is the First Sign of Kidney Problems?

Spoiler alert: It’s usually something small.

The first sign of kidney problems is often subtle, maybe you’re peeing more (or less), or you’re more tired than usual. Some folks also notice mild swelling in their ankles or hands.

This is the moment to act. A simple urine or blood test can reveal signs like elevated creatinine or protein in the urine, clues your kidneys need help with.

You can get this testing done as part of our in-house lab services.

Kidney Disease Symptoms in Females

Ladies, your symptoms might look a little different.

Common signs in females include:

• More frequent urinary tract infections (UTIs)
  Pelvic or abdominal pressure
• Back pain that’s often mistaken for period cramps
• Menstrual irregularities due to hormonal imbalance

Kidney disease symptoms in females can be subtle or mistaken for other issues due to hormonal and anatomical factors. Women should watch for urinary changes, fatigue, and swelling.

Our women’s health services support early and accurate diagnosis.

Kidney Stones, Infections, and Other Red Flags

You might be wondering: Are kidney stones related to kidney disease? Short answer—kind of.

While kidney stones don’t directly cause kidney disease, recurrent stones or infections can damage your kidneys over time.

So, what do kidney stones feel like?

• Sharp, stabbing pain in the back or side
• Pain that comes in waves
• Nausea or vomiting
• Burning or blood in the urine

These signs deserve attention, especially if they happen often.

Kidney Infections (Pyelonephritis):

• Fever or chills
• Lower back pain
• Urgent or painful urination
• Cloudy or foul-smelling urine

Repeated infections can scar your kidneys and lead to chronic issues.

Uncommon Signs: When to Pay Closer Attention

Here are some lesser-known symptoms that may be worth checking out:

Kidney Disease Nails

Changes in your nails might be a sign:

• Pale nail beds
• Brown or white bands (Muehrcke’s lines)

Metallic Taste in Mouth

If your breath smells like ammonia or your food tastes weird, toxins might be backing up in your system.

Persistent Nausea or Appetite Loss

Feeling queasy without reason? Not eating as much? It could be more than just a stomach bug.

Confusion or Trouble Focusing

Your brain needs clean blood to function well. Toxin buildup can affect your clarity and concentration.

When to See a Doctor & What to Expect

Don’t wait until the symptoms get worse. If something feels off, talk to your doctor.

Ask for these tests:

• Blood test to check creatinine and estimate your GFR (glomerular filtration rate)
• Urine test to look for protein, blood, or infection
• If you have high blood pressure or diabetes, ask for a nephrology referral
