What are the symptoms of kidney failure in adults

What It’s Like to Have Kidney Failure

Your kidneys are the body’s behind-the-scenes cleanup crew, filtering blood, producing pee, and regulating your fluids and body’s electrolytes. When they begin to fail, the body sends up warning signals; some subtle, others blaring. In chronic cases, these symptoms may come on slowly, while in acute cases, they can hit like a freight train. Let’s take a look at the most frequent symptoms of kidney failure in adults, arranged based on how they make you feel, with a reminder of what they might look like in your daily routine.

1. Fatigue and Weakness

Feeling bone-tired all the time is one of the first signs of kidney failure. You might drag yourself out of bed feeling like you ran a marathon in your sleep, or simple chores like vacuuming could leave you wiped out. This happens because failing kidneys can cause anemia, meaning fewer red blood cells to carry oxygen to your muscles and brain. Without oxygen, your energy plummets.

Picture this: you’re too exhausted to join your friends for a coffee run or dozing off during your favorite TV show. This isn’t just “I’m busy” tiredness; it lingers, no matter how much you rest.

2. Swelling (Edema)

When kidneys can’t remove excess fluid, it builds up in your body, causing swelling, or edema. You’ll likely notice it in your legs, ankles, feet, hands, or face. Your shoes might feel tight by noon, or your face could look puffy, especially around the eyes. In severe cases, your socks might leave deep indents in your skin.

Imagine trying to button your jeans, but your ankles are so swollen they look like they belong to someone else. That’s edema, and it’s a big clue your kidneys are struggling.

3. Changes in Urination

Since kidneys produce urine, it makes sense that failure affects your bathroom habits. You might see:

• Less urine: Producing little to no urine because the kidneys aren’t filtering well.
• Frequent urination: Especially at night, as kidneys lose their ability to concentrate urine.
• Foamy urine: A sign of protein leaking into the urine due to kidney damage.
• Blood in the urine: Urine might look pink, red, or dark, indicating blood.
• Painful urination: Burning or discomfort, often tied to infections or blockages.

For example, you might wake up multiple times to pee, only to notice your urine looks odd or smells strange. These changes are your body’s SOS.

4. Shortness of Breath

Struggling to breathe, even when you’re just sitting down, can signal kidney failure. This happens because fluid builds up in the lungs (pulmonary edema) or anemia limits oxygen delivery. You might feel winded after light activity or wake up gasping for air.

Think of trying to chat with a friend but pausing to catch your breath after every sentence. This symptom can be alarming and often pushes people to seek help.

5. High Blood Pressure

Kidneys help control blood pressure, so when they fail, it can spike. You might not feel high blood pressure, but it can cause headaches, dizziness, or nosebleeds. If you check your blood pressure at home, readings above 140/90 mmHg could be a red flag.

It’s like your body’s pressure gauge is stuck on high, and without the kidneys to regulate it, things can get out of control fast.

6. Itchy Skin

Constant itching, especially without a rash, is a sneaky symptom of kidney failure. Toxins like urea or phosphorus build up in the blood when the kidneys can’t clear them, irritating your skin. You might scratch your arms or legs relentlessly, and no moisturizer helps.

Imagine an itch that feels like it’s under your skin, keeping you up at night. It’s frustrating and a clear sign that something’s off internally.

7. Nausea, Vomiting, and Loss of Appetite

Toxins accumulating in the blood (uremia) can make you feel nauseous, trigger vomiting, or kill your appetite. Food might taste metallic, or the thought of eating could turn your stomach. Some describe it as feeling like they’re always on the edge of a stomach bug.

For instance, your go-to comfort food might suddenly seem gross, or you’re losing weight without trying. These are clues that your kidneys aren’t clearing waste properly.

8. Muscle Cramps and Twitching

Electrolyte imbalances (think low calcium or high potassium) can cause muscle cramps, twitching, or restless legs. You might get painful cramps in your calves or feel like your legs are jittery at night. This is more common in chronic kidney failure.

Picture trying to unwind, but your legs keep cramping or jerking. It’s not just annoying; it’s your body signaling an electrolyte problem.

9. Confusion or Brain Fog

When toxins build up, they can cloud your brain, confusion, trouble concentrating, or memory issues. You might feel like you’re in a mental fog, struggling to follow a conversation or complete simple tasks. In rare, severe cases, this can lead to seizures.

Imagine trying to plan your day, but your brain feels like it’s stuck in quicksand. This fog is a serious symptom that needs attention.

10. Chest Pain or Pressure

Fluid buildup around the heart or lungs can cause chest pain or a heavy, pressing feeling. This is more common in advanced cases and can feel like something’s squeezing your chest. If severe, it’s an emergency.

If your chest feels tight or heavy, especially with shortness of breath, don’t wait; get help immediately.

How Symptoms Affect Daily Life?

Kidney failure symptoms can be deceptive. You might blame fatigue on a hectic schedule, swelling on too much standing, or nausea on bad takeout. But when they persist or combine, they disrupt your routine. You might skip outings because you’re too tired, avoid meals because nothing tastes right, or feel self-conscious about puffy legs or constant scratching. Over time, these changes can wear you down physically and emotionally.

Acute vs. Chronic Symptoms

• Acute kidney failure: Symptoms hit fast, often within days. Think sudden swelling, minimal urine, or intense fatigue. Causes include dehydration, infections, or blockages like kidney stones.
• Chronic kidney failure: Symptoms creep in over months or years. Early on, you might feel fine, but later, fatigue, itching, and swelling become noticeable. Common causes are diabetes, hypertension, or autoimmune conditions.

When to Get Help

If these symptoms sound familiar—especially if they’re ongoing or worsening—don’t ignore them. Kidney failure is serious, but catching it early can slow or even reverse damage. See a doctor if you notice:

• Persistent swelling
• Weird changes in urination (less, bloody, or foamy)
• Constant fatigue, breathlessness, or confusion
• Severe itching or nausea disrupting your life

Your doctor might run blood tests (like creatinine), urine tests, or imaging to check your kidneys. Acting fast is key.
