10 Early Signs You Might Have Kidney Disease
Kidney disease often presents with subtle early signs that can easily be overlooked. However, being aware of these indications can help individuals recognize potential kidney problems and take appropriate action. Here are ten early signs that might indicate kidney disease:
1. Changes in Urination Patterns
Changes in urination patterns can be an early indication of kidney disease. The kidneys play a vital role in filtering waste products and excess fluids from the blood to produce urine. When the kidneys are not functioning properly, several changes in urination patterns may occur, including:
- Increased frequency of urination: Needing to urinate more often than usual, particularly at night, may be a sign of kidney disease.
- Decreased urine output: Producing less urine than usual or experiencing a decrease in the volume of urine can be a symptom of kidney dysfunction.
- Changes in urine color: Darker urine or blood in the urine (hematuria) may indicate a problem with the kidneys.
- Foamy urine: Excessive foam or bubbles in the urine can be a sign of proteinuria, where protein leaks from the kidneys into the urine.
These changes in urination patterns can be caused by the kidneys’ reduced ability to filter waste products and excess fluid properly. If you notice any of these changes, it is essential to consult a healthcare professional for further evaluation and appropriate management.
2. Swelling in Feet, Ankles, or Hands
Swelling, also known as edema, in the feet, ankles, or hands can be a noticeable indication of kidney disease. The kidneys are responsible for maintaining fluid balance in the body by filtering out excess fluid and waste products. When the kidneys are damaged or not functioning optimally, they may struggle to remove the extra fluid, leading to swelling in the extremities.
The accumulation of fluid can cause discomfort, tightness, and puffiness in the affected areas. Individuals with kidney disease may find that their shoes or rings no longer fit properly due to the swelling.
It is important to note that swelling in the feet, ankles, or hands can be caused by various factors, including prolonged sitting or standing, certain medications, and venous insufficiency. However, if the swelling persists or is accompanied by other symptoms, such as changes in urine output or high blood pressure, it is advisable to consult a healthcare professional for a thorough evaluation.
3. Fatigue and Weakness
Fatigue and weakness are common symptoms experienced by individuals with chronic kidney disease. The kidneys play a crucial role in producing a hormone called erythropoietin, which stimulates the production of red blood cells in the bone marrow. Red blood cells carry oxygen to the body’s tissues and organs, providing energy for daily activities. Without enough erythropoietin, individuals may have a hard time catching their breath and may experience shortness of breath or feelings of drowning, especially when lying down.
In chronic kidney disease, the kidneys may not produce enough erythropoietin, leading to a decrease in red blood cell production. This condition, known as anemia, can result in fatigue, weakness, and a general feeling of low energy.
Additionally, the buildup of waste products in the blood due to impaired kidney function can contribute to feelings of fatigue and overall body weakness. These symptoms may be more pronounced during physical exertion or in advanced stages of kidney disease.
If you consistently experience fatigue and weakness, it is important to consult a healthcare professional to determine the underlying cause and appropriate management strategies.
4. Difficulty Sleeping
Difficulty sleeping, including insomnia and restless sleep, can be an indication of kidney disease. Kidney failure and the associated buildup of waste products in the blood can disrupt the body’s normal sleep patterns, leading to sleep disturbances.
The kidneys play a crucial role in maintaining the balance of electrolytes, such as potassium and calcium, in the body. When the kidneys are not functioning properly, electrolyte imbalances can occur, affecting various bodily functions, including sleep regulation.
Additionally, the accumulation of toxins in the blood can cause itching, which can interfere with sleep quality. Dry and itchy skin, another symptom of kidney disease, can further contribute to sleep problems.
If you are experiencing chronic sleep difficulties, it is recommended to consult a healthcare professional for proper evaluation and guidance. Addressing the underlying cause, such as kidney disease, can help improve sleep quality and overall well-being.
5. Dry and Itchy Skin
Dry and itchy skin can be a noticeable indication of kidney disease. The kidneys play a crucial role in maintaining the body’s fluid balance and removing waste products from the blood. When the kidneys are not functioning properly, waste products and toxins can build up in the bloodstream, leading to skin-related symptoms.
Kidney disease can cause a decrease in the production of sweat and oil glands in the skin, resulting in dryness and itching. The accumulation of waste products in the blood can also irritate the skin and cause itching.
Additionally, imbalances in electrolytes, such as calcium and phosphorus, can contribute to skin problems. Calcium deposits in the skin, known as calciphylaxis, can cause painful and itchy skin lesions.
If you are experiencing persistent dryness and itching of the skin, it is advisable to consult a healthcare professional for proper evaluation and management. They can help identify the underlying cause, such as kidney disease, and recommend appropriate treatment options.
6. Blood in Urine
The presence of blood in the urine, also known as hematuria, can be a significant indication of kidney disease. Healthy kidneys filter waste products from the blood and prevent red blood cells from entering the urine. However, when the kidneys are damaged or not functioning properly, red blood cells may leak into the urine, which can be detected through an ultrasound, CT scan, MRI, or kidney biopsy.
Blood in the urine can be visible to the naked eye, resulting in pink, red, or cola-colored urine. In some cases, blood in the urine may not be easily detectable and can only be identified through urine tests.
It is important to note that blood in the urine can be caused by various factors, including urinary tract infections, kidney stones, and bladder or kidney infections. However, if blood in the urine persists or is accompanied by other symptoms associated with kidney disease, such as changes in urination patterns or swelling, it is advisable to consult a healthcare professional for further evaluation and appropriate management.
7. Persistent Puffiness Around the Eyes
Persistent puffiness around the eyes, also known as periorbital edema, can be an indication of kidney problems. The kidneys play a vital role in maintaining fluid balance in the body, filtering out excess fluid and waste products. When the kidneys are not functioning optimally, fluid retention can occur, leading to puffiness and swelling, particularly around the eyes.
Periorbital edema can be more pronounced in the morning and may improve throughout the day. However, if the puffiness persists or is accompanied by other symptoms associated with kidney disease, such as changes in urine output or high blood pressure, it is advisable to consult a healthcare professional for further evaluation and appropriate management.
It is important to note that periorbital edema can also be caused by factors such as allergies, sinus problems, and inadequate sleep. Therefore, a healthcare professional can help determine the underlying cause and provide appropriate treatment options.
8. High Blood Pressure
High blood pressure, also known as hypertension, can be both a cause and an indication of kidney disease. The kidneys play a crucial role in regulating blood pressure by balancing the amount of fluid and salt in the body. When the kidneys are not functioning properly, they may struggle to maintain this balance, resulting in high blood pressure.
Persistent high blood pressure can damage the blood vessels in the kidneys and impair their ability to filter waste products and excess fluids effectively. This, in turn, can further contribute to the progression of kidney disease.
It is important to monitor blood pressure regularly, as hypertension often does not present with noticeable symptoms. If you have high blood pressure, it is crucial to work with a healthcare professional to manage and control your blood pressure to reduce the risk of kidney disease and its complications.
9. Decreased Appetite
Decreased appetite can be an indication of kidney disease. The buildup of waste products and toxins in the bloodstream due to impaired kidney function can affect the sense of taste and appetite.
Additionally, individuals with kidney disease may experience nausea and vomiting, which can further contribute to a decreased appetite. The accumulation of waste products can also cause gastrointestinal symptoms, such as a metallic taste in the mouth and a general feeling of discomfort after eating.

How Kidneys Filter Blood and Manage Waste
The kidneys filter blood and manage waste through a complex process known as glomerular filtration. Here is an overview of how the kidneys filter blood and remove waste products:
- The process begins in the glomerulus, a network of blood vessels in the kidneys. As blood flows through the glomerulus, waste products, excess fluids, and electrolytes pass through the walls of the blood vessels into tiny structures called nephrons.
- Nephrons are the functional units of the kidneys. Each kidney contains millions of nephrons, which consist of a glomerulus and a tubule.
- The tubules reabsorb essential substances, such as glucose, water, and electrolytes, back into the bloodstream, while waste products and excess fluids continue their journey through the tubules.
- Finally, the waste products and excess fluids collected in the tubules form urine, which is transported to the bladder for elimination from the body.
The glomerular filtration rate (GFR) is a measure of kidney function that indicates how efficiently the kidneys are filtering waste products from the blood. A decrease in the GFR can be indicative of kidney disease or dysfunction.
Factors That Can Increase Risk of Developing Kidney Disease
Several factors can increase the risk of developing kidney disease. Understanding these risk factors can help individuals take preventive measures and seek timely medical attention. Here are some significant factors that can increase the risk of kidney disease:
Diabetes: A Leading Cause
Diabetes is a leading cause of kidney disease. Both type 1 and type 2 diabetes can damage the blood vessels and small filtering units in the kidneys, leading to kidney damage. Uncontrolled blood sugar levels can further exacerbate kidney damage by increasing the workload on the kidneys.
High blood sugar levels over time can cause the kidneys to filter too much blood, leading to increased pressure on the delicate filtering units. This can result in the thickening and scarring of the blood vessels, impairing the kidneys’ ability to function properly.
Proper management of diabetes, including blood sugar control, regular monitoring, and lifestyle modifications, is essential in reducing the risk of kidney disease. Individuals with diabetes should work closely with their healthcare providers to develop a comprehensive treatment plan that includes regular kidney function monitoring and appropriate management strategies.
High Blood Pressure and Its Effects
High blood pressure, also known as hypertension, is a significant risk factor for kidney disease. The sustained elevation of blood pressure can damage the blood vessels in the kidneys, impairing their ability to filter waste products and fluids properly. Over time, this can lead to chronic kidney disease and potentially kidney failure as the kidneys are not receiving enough oxygen due to the narrowed blood vessels.
Additionally, hypertension can cause further damage to the blood vessels throughout the body, increasing the risk of heart disease, stroke, and other cardiovascular complications. The combination of high blood pressure and kidney disease can create a detrimental cycle, as kidney dysfunction can contribute to further increases in blood pressure.
Proper management of hypertension, including lifestyle modifications and medication management, is essential in reducing the risk of kidney disease and its complications. Regular blood pressure monitoring, adherence to prescribed medications, and lifestyle modifications, such as a healthy diet and regular exercise, can help maintain blood pressure within a healthy range and protect kidney function. If you have high blood pressure, it is important to consult with a nephrologist (kidney doctor) to develop a personalized treatment plan to protect your kidney health.
Diagnostic Tests for Kidney Disease
Diagnostic tests play a crucial role in identifying and monitoring kidney disease. Early detection can enable timely intervention and management to slow disease progression. Here is an overview of the diagnostic tests used for kidney disease:

- Blood urea nitrogen (BUN) test: The BUN test measures the level of urea nitrogen, a waste product of protein metabolism, in the blood. Elevated BUN levels can suggest decreased kidney function.
- Glomerular filtration rate (GFR): The GFR is a calculated value based on blood creatinine levels, age, sex, and other factors. It estimates how efficiently the kidneys are filtering waste products from the blood. A decreased GFR can indicate kidney dysfunction.
These blood tests provide valuable information about kidney function and can help healthcare providers monitor the progress of kidney disease and guide treatment decisions.
Urine Tests and What They Indicate
Urine tests are commonly used to assess kidney health and detect abnormalities that may indicate kidney disease. Here are some urine tests used in the evaluation of kidney function:
- Urinalysis: This test involves analyzing a urine sample for various substances, such as red and white blood cells, protein, glucose, and waste products. Abnormal levels of these substances can provide clues about kidney function and potential kidney disease.
- Proteinuria test: Proteinuria is the presence of excessive protein in the urine, which can be an indication of kidney damage. A proteinuria test measures the amount of protein present in the urine and helps identify the presence and severity of kidney disease.
Here is an example of a text table that provides information about urine test results and their implications:
| Test Result | Implication |
| Normal | No significant abnormalities detected in urine composition. |
| Presence of protein | Proteinuria, which may indicate kidney damage or dysfunction. |
| Presence of blood | Hematuria, which can be caused by various factors, including kidney stones, infections, or injury. |
| Abnormal glucose level | Glycosuria, which may indicate impaired kidney function or diabetes. |
These urine tests, along with other diagnostic tools, help healthcare providers assess kidney function and identify potential kidney disease.
