Stage 4 chronic kidney disease means your kidneys are only working at 15-29 percent. This is a serious stage where kidneys can fail completely. Spotting the signs early is key to managing the disease and keeping your quality of life good.
The Centers for Disease Control and Prevention say over one in seven U.S. adults have chronic kidney disease (CKD). But, up to nine in 10 with CKD don’t know they have it. Symptoms at this stage include constant tiredness, swelling in your legs and feet, and changes in how you pee.
It’s vital to know these warning signs to get help quickly. We’ll look at the seven main signs of stage 4 kidney disease. This will help you or your loved ones get medical help and improve your health.
What Stage 4 Kidney Disease Means for Your Body

When you reach Stage 4 CKD, your kidneys don’t work well. It’s important to know how this affects your health.
Stage 4 CKD means your kidneys work between 15% and 29% of normal. This makes it hard for your body to remove waste and extra fluids. The kidneys are key to keeping you healthy. If they don’t work right, toxins can build up.
The estimated glomerular filtration rate (eGFR) shows how bad kidney disease is. An eGFR of 15 to 29 means serious kidney damage. We use eGFR to see how well your kidneys filter waste. Regular eGFR tests help us track kidney disease and change treatment plans.
When kidneys don’t work well, waste like creatinine and urea builds up. This can cause tiredness, nausea, and swelling. Knowing how waste buildup affects you is key to managing Stage 4 CKD. We help patients by closely monitoring and treating these problems.

Stage 4 chronic kidney disease (CKD) is a serious condition that needs quick medical help. At this stage, the kidneys work at only 15-29% of their normal level.
Patients with stage 4 CKD face many health problems. Getting help fast is very important. This condition affects many parts of a person’s health.
One big worry for stage 4 CKD patients is losing their kidneys completely. Without the right care, the disease can get worse fast. This might mean needing dialysis or a kidney transplant.
Stage 4 CKD patients also have a higher risk of heart disease. Kidney disease and heart health are linked. Fluid overload, electrolyte imbalances, and toxin buildup can harm the heart. So, taking care of the heart is key in treating stage 4 CKD.
When kidneys don’t work well, waste builds up in the blood. This can lead to anemia, bone disease, and more heart problems. Quick and good care for stage 4 CKD can help avoid these issues. It can also improve a patient’s life quality.
In Stage 4 CKD, kidneys work at 15-29% capacity. This leads to severe fatigue and weakness. These symptoms make everyday tasks hard to do.
Anemia is a big reason for fatigue in Stage 4 CKD patients. It happens when the body doesn’t have enough red blood cells. This is because kidneys don’t make enough erythropoietin (EPO), a hormone needed for red blood cell production.
Many CKD patients suffer from anemia. Up to 50-60% of those with advanced kidney disease have it. For dialysis patients, nearly 97% are affected.
Toxins in the blood also cause fatigue in Stage 4 CKD. Normally, kidneys remove waste from the blood. But in Stage 4, they can’t do this well, leading to toxin buildup.
These toxins harm energy production in the body. This results in weakness and tiredness. Treating toxin buildup is key to feeling better.
Factors Contributing to Fatigue | Impact on Patients |
Anemia | Reduces oxygen delivery to tissues, causing weakness and tiredness |
Toxin Buildup | Affects energy metabolism, leading to fatigue |
If you’re always tired, tell your nephrologist. They can help manage anemia and other causes. This can greatly improve your life.
Discuss how tired you are and any other symptoms with your doctor. Together, you can find ways to manage your fatigue and other Stage 4 CKD symptoms.
When kidneys start to fail in stage 4 CKD, people often see swelling in their arms and legs. This swelling, called edema, shows that the kidneys can’t get rid of extra fluid. It’s a big sign that something is wrong.
In stage 4 CKD, kidneys can’t filter waste and extra fluids well. “The kidneys are key to keeping fluid balance in the body,” but when they don’t work right, fluid builds up. This leads to swelling.
This swelling is not just about looks. It shows that kidneys are struggling and need attention.
Edema usually shows up in the lower parts of the body, like ankles and feet. This is because gravity pulls fluid down. But it can also happen in the hands. Watching these areas for swelling can tell us a lot about fluid levels in the body.
People often notice swelling gets worse during the day, after being on their feet a lot. It’s important to notice these changes to handle them well.
Tracking daily weight changes can help spot fluid retention. A quick weight gain means fluid buildup. “We suggest patients weigh themselves at the same time each day to catch any changes,” as even small shifts are important.
By watching weight and noticing edema signs, patients can work with doctors to improve their treatment. This helps manage fluid better.
Stage 4 CKD can cause toxins to build up in the blood. This leads to nausea and a drop in appetite. About 30-40% of people with chronic kidney disease experience this, feeling sick to their stomach.
The kidneys filter waste from the blood. When they fail, waste products, or uremic toxins, build up. These toxins can slow down digestion and cause nausea, making it hard to eat.
Patients with Stage 4 CKD often have a metallic taste in their mouth. This can make food unappealing, leading to less appetite. The mix of nausea and bad taste can really hurt a patient’s ability to eat well.
Dealing with nausea and less appetite needs a careful plan. Patients can try eating smaller, more frequent meals that are easy to digest. Working with healthcare providers, like renal dietitians, can help create a diet plan that works. It’s also important to manage fluid balance to avoid dehydration, which can make nausea worse.
Understanding why nausea and less appetite happen in Stage 4 CKD helps patients manage these symptoms. This way, they can keep their nutrition on track.
People with stage 4 chronic kidney disease often notice changes in how they urinate. These changes show that the kidneys are not working well. They can be signs that the disease is getting worse.
One thing you might notice is how your urine looks. Foamy urine means you might have proteinuria, where proteins leak into your urine. Discolored urine, like being darker or having blood in it, can also be a sign of problems.
Seeing these changes can be scary. But it’s important to tell your doctor right away. They can help figure out what’s going on with your kidneys.
Another sign is changes in how often you need to pee. Some people pee a lot, while others pee less. These changes can mean the kidneys are not working right.
It’s key to keep track of these changes. Writing down when you pee can help your doctor understand your situation. They can then adjust your treatment as needed.
Proteinuria is when there’s too much protein in your pee. It’s a sign of kidney damage. It’s called a “silent danger” because you might not notice it at first.
Working with your nephrologist is important to manage proteinuria. They might suggest changes to your diet, medication, or regular check-ups to slow down kidney disease.
Living with Stage 4 Kidney Disease: Essential Monitoring
For those with stage 4 kidney disease, regular check-ups are key. They help keep overall health in check. This stage of chronic kidney disease (CKD) needs a proactive approach to slow disease progression.
Patients with stage 4 CKD need to see their healthcare provider at least four times a year. These visits help track the disease’s progress. They also allow for treatment adjustments and early problem solving.
Key Components of Regular Check-ups:
Critical blood tests are essential for stage 4 CKD monitoring. They check kidney function and detect complications. They also guide treatment plans.
Blood Test | Purpose | Significance in Stage 4 CKD |
Creatinine | Measures kidney function by assessing waste removal | Helps determine the stage of CKD and monitor progression |
Hemoglobin | Assesses for anemia, a common complication of CKD | Identifies the need for erythropoietin therapy or iron supplements |
Calcium | Monitors mineral and bone disorder associated with CKD | Helps manage bone health and prevent complications like osteoporosis |
Patients can also monitor their health at home. Tracking blood pressure and fluid intake is important. Watching for signs of edema or other complications is also key.
Tips for Effective Home Monitoring:
Combining regular medical check-ups with home monitoring helps manage stage 4 CKD. It improves quality of life for those affected.
Dry and itchy skin is common in stage 4 kidney disease. This symptom, called pruritus, can really affect a person’s life. Severe itching affects up to 70% of people on hemodialysis, making it a big problem.
Phosphorus buildup in the blood can cause dry and itchy skin in stage 4 CKD patients. When kidneys don’t work well, they can’t filter out phosphorus. This buildup can make the skin itch and get irritated. It’s important to control phosphorus levels through diet and medicine to ease skin problems.
People with stage 4 CKD should watch for skin changes that might mean health problems. These can include dry skin, changes in skin color, and crystals on the skin. It’s key to notice these changes and tell a healthcare provider.
There are ways to help with dry and itchy skin in stage 4 CKD. These include:
By trying these steps, patients can get a lot of relief from itchy skin. It’s also vital to work with a healthcare provider to take care of kidney health and manage symptoms.
In stage 4 CKD, patients may feel numbness and tingling. This is due to peripheral neuropathy. It happens when toxins in the blood damage nerves. We’ll look at how this affects patients and their health.
Peripheral neuropathy is common in advanced CKD. It’s caused by toxins in the blood damaging nerves. This can make hands and feet feel numb and tingle.
It’s important to understand the connection between neuropathy and CKD. If you notice numbness or tingling, talk to your doctor. They can help find the best way to manage your symptoms.
Not all numbness or tingling comes from kidney disease. Diabetes or vitamin deficiencies can also cause these symptoms. It’s key to work with your doctor to figure out the cause.
Diagnostic tests can help find the cause. These might include nerve tests or blood work. This way, you can get the right treatment.
Numbness and tingling can be scary, but sometimes they mean something serious. If you have sudden numbness with weakness or trouble speaking, get help right away.
Knowing when to seek emergency care is important. Stay alert to your symptoms and talk to your doctor about them. This can help avoid bigger problems.
Stage 4 kidney disease often leads to sleep problems. These issues can greatly affect a person’s health and happiness. It’s important to understand these symptoms.
Restless Legs Syndrome (RLS) makes people feel like they must move their legs. It’s common in those with stage 4 CKD. To better sleep, try these tips:
Sleep apnea is another sleep problem linked to stage 4 kidney disease. It causes breathing to stop or get shallow during sleep. This can lead to heart problems, making it very important to treat.
Signs of sleep apnea include:
To improve sleep for those with stage 4 CKD, we need a detailed plan. Work with your doctor to manage symptoms. This might include:
By tackling sleep issues, patients with stage 4 kidney disease can feel better and live a fuller life.
Managing stage 4 CKD requires a mix of medicine, diet changes, and getting ready for future treatments. As the disease gets worse, a detailed treatment plan is vital. It helps slow down the disease and manage symptoms.
Medicine is key in treating stage 4 CKD. Keeping blood pressure in check is very important. High blood pressure can make the disease worse. ACE inhibitors and ARBs help control blood pressure and reduce protein in the urine.
Other medicines help with problems like anemia, bone issues, and imbalances in electrolytes. For example, erythropoiesis-stimulating agents fight anemia, and phosphate binders keep phosphorus levels right.
Medication Type | Purpose | Examples |
ACE inhibitors | Control blood pressure, reduce proteinuria | Lisinopril, Enalapril |
ARBs | Control blood pressure, reduce proteinuria | Losartan, Valsartan |
Erythropoiesis-stimulating agents | Treat anemia | Epoetin alfa, Darbepoetin alfa |
Phosphate binders | Manage phosphorus levels | Sevelamer, Calcium carbonate |
Changing your diet is very important in managing stage 4 CKD. A renal dietitian can create a diet plan that limits harmful nutrients like sodium, potassium, and phosphorus.
A good diet plan can help manage symptoms, slow disease progress, and keep you healthy. Nutritional counseling is a key part of caring for CKD.
As stage 4 CKD gets worse, getting ready for renal replacement therapy (RRT) is important. RRT includes hemodialysis, peritoneal dialysis, and kidney transplantation. Each has its own benefits and drawbacks, depending on the patient’s needs and wishes.
A team of healthcare professionals can guide patients through these choices. Early preparation is key to a smooth transition to RRT when needed.
