There are various possible causes for this condition, which reflects related kidney damage caused by the underlying health issue. This kidney damage has five possible stages, with the classification based on kidney damage and functionality. Staging is an important component of the medical treatment plan, with next-steps taking into account the severity of the disease.<\/p>\n<p>This article will cover the basics of chronic kidney disease, focusing on patients in stage 3 and the common causes of this condition. It will also discuss typical diagnosis and treatment methods, along with what to expect during this process.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is chronic kidney disease?<\/h2>\n<p>The kidneys&#8217; role in the body is to produce erythropoietin (a hormone) to stimulate red blood cell production, maintain blood pressure, regulate the balance of certain minerals and remove excess water and waste products. When kidneys become damaged, these functions become less effective, which can lead to various health problems and imbalances.<\/p>\n<p>Chronic kidney disease (CKD) refers to the gradual loss of kidney function or damage over a period of at least three months. The extent of kidney damage depends on factors such as how long the patient has had CKD and the underlying condition that caused it. There is no single cause for CKD, but multiple conditions can lead to it. The causes will be discussed in the next section.<\/p>\n<p>&nbsp;<\/p>\n\n<div class=\"cta-banner\">\n\t<div class=\"cta-text\">\n\t\t<h2>\n\t\t\tAccess your medical imaging &amp; reports from over 900 hospitals and clinics.\t\t<\/h2> \n\t<\/div>\n\t<div class=\"cta-search\">\n\t\t<div class=\"request-search-bar request-search-bar--type-general\"><request-search-bar [deviceId]=\"amplitude.getInstance().options.deviceId\"><\/request-search-bar><\/div>\t<\/div>\n<\/div>\n\n\n<p>&nbsp;<\/p>\n<h2>How is chronic kidney disease staged?<\/h2>\n<p>CKD is classified into <a href=\"https:\/\/diabetes.org\/sites\/default\/files\/2024-04\/know-the-stages.pdf\" target=\"_blank\" rel=\"noopener\">five possible stages<\/a>. Here is a brief overview of what each stage means:<\/p>\n<ul>\n<li><strong>Stage 1:<\/strong> Kidney damage is mild, and kidney function remains normal<\/li>\n<li><strong>Stage 2:<\/strong> Kidney function is still good, and the damage is still mild<\/li>\n<li><strong>Stage 3a:<\/strong> Kidney function is less than optimal, with mild to moderate damage<\/li>\n<li><strong>Stage 3b:<\/strong> Kidney function is suboptimal, with moderate to severe damage<\/li>\n<li><strong>Stage 4:<\/strong> Kidneys are severely damaged and function minimally<\/li>\n<li><strong>Stage 5:<\/strong> Kidneys are extremely damaged and either barely function or no longer function at all<\/li>\n<\/ul>\n<p>The staging of chronic kidney disease depends on specific parameters from blood and urine tests, as well as the extent of damage the kidneys have sustained. More details on these diagnostic methods will be discussed later in this article. As for stage 3 specifically, it\u2019s important to remember that while there may be some kidney damage, there is still significant kidney function. With proper medical treatment, much can be done to slow further damage.<\/p>\n<p>&nbsp;<\/p>\n<h2>What are the symptoms of stage 3 chronic kidney disease?<\/h2>\n<p>Many patients with stage 3 chronic kidney disease don\u2019t display any symptoms. Others, however, do experience some, as this tends to be the stage where CKD causes more health issues. Some possible symptoms include:<\/p>\n<ul>\n<li>Lower back pain<\/li>\n<li>Dry or itchy skin<\/li>\n<li>Cramping in muscles<\/li>\n<li>Fatigue and feeling weak<\/li>\n<li>Sleeping difficulties<\/li>\n<li>Swelling in the feet and hands<\/li>\n<li>Foamy or dark colored urine<\/li>\n<li>Decreased or increased urination<\/li>\n<li>Restless leg syndrome<\/li>\n<li>Unexplained weight loss<\/li>\n<li>Nausea<\/li>\n<li>Loss of appetite<\/li>\n<\/ul>\n<p>It\u2019s important to remember that many of these symptoms can have causes unrelated to chronic kidney disease. Their presence doesn\u2019t necessarily indicate CKD, so patients should discuss them with their doctor to determine the next steps and consider appropriate testing.<\/p>\n<p>&nbsp;<\/p>\n<h2>What causes chronic kidney disease stage 3?<\/h2>\n<p>CKD tends to be caused when an underlying disease or condition affects kidney function. There are multiple possibilities for this, but here are some more common causes:<\/p>\n<ul>\n<li><strong>High blood pressure:<\/strong> Also known as hypertension.<\/li>\n<li><strong>Genetic kidney diseases:<\/strong> Such as polycystic kidney disease.<\/li>\n<li><strong>Diabetes:<\/strong> Both Type 1 and Type 2 can cause CKD.<\/li>\n<li><strong>Glomerulonephritis:<\/strong> Inflammation of the glomeruli (which help the kidneys filter waste).<\/li>\n<li><strong>Vesicoureteral reflux:<\/strong> A condition where urine backs up into the kidneys.<\/li>\n<li><strong>Interstitial nephritis:<\/strong> Kidney tubule inflammation.<\/li>\n<li><strong>Prolonged urinary tract obstruction:<\/strong> This can be caused by <a href=\"https:\/\/www.pockethealth.com\/2024\/12\/03\/ct-scan-kidney-stones\/\">kidney stones<\/a>, certain cancers and enlarged prostates.<\/li>\n<li><strong>Recurring kidney infections:<\/strong> Also referred to as pyelonephritis.<\/li>\n<li><strong>Kidney damage from drug use:<\/strong> Illicit drugs can cause kidney damage over time.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>How is chronic kidney disease diagnosed?<\/h2>\n<p>There are several methods to help doctors diagnose chronic kidney disease and determine its stage. Here are the most common tests.<\/p>\n<h3>Blood tests<\/h3>\n<p>There are two primary methods used to stage CKD. The first test is the <a href=\"https:\/\/www.kidneyfund.org\/all-about-kidneys\/tests\/blood-test-egfr\" target=\"_blank\" rel=\"noopener\">estimated glomerular filtration rate (eGFR)<\/a>. Glomeruli are tiny filters within the kidneys that help remove toxins from the body. When they don\u2019t function properly, as in chronic kidney disease, more toxins build up in the bloodstream, which is why blood levels are tested. It&#8217;s important to note that low-functioning glomeruli can be caused by factors other than CKD. Additionally, a normal eGFR does not always rule out kidney disease, as some levels of kidney damage may not be detected. For this reason, eGFR is typically repeated over time, and other evaluation methods are used alongside it.<\/p>\n<h3>Urine tests<\/h3>\n<p>Another test used to help diagnose CKD is a urine analysis that looks for a protein called albumin. This protein is typically found in the blood, not the urine, and plays a role in muscle repair, muscle building and fighting infection. If albumin is detected in the urine, it may indicate that the kidneys are not functioning properly, allowing this protein to leak through the glomeruli filters. While the presence of albumin in the urine can suggest chronic kidney disease, it&#8217;s important to note that other factors such as dehydration, infection, hypertension and diabetes can also cause this result.<\/p>\n<h3>Medical imaging<\/h3>\n<p>Because staging is partially dependent on assessing kidney damage, medical imaging is a valuable tool for CKD diagnosis. Here are the most common imaging types used to evaluate kidney health:<\/p>\n<ul>\n<li><strong>Magnetic resonance imaging (MRI):<\/strong> <a href=\"https:\/\/www.pockethealth.com\/2024\/07\/25\/mri-preparation\/\">MRIs<\/a> use magnetic fields and radio waves to create detailed internal images of the patient\u2019s organs and surrounding structures. The patient lies still in the tube-like MRI machine, which produces scans that can reveal potential kidney damage or blockages.<\/li>\n<li><strong>Ultrasounds:<\/strong> <a href=\"https:\/\/www.pockethealth.com\/2024\/07\/04\/abdominal-ultrasound-preparation\/\">Ultrasounds<\/a> use high-frequency sound waves produced by a handheld device called a transducer. The transducer is moved externally across the kidney area, and the sound waves bounce off internal organs and structures, creating images that are captured for analysis.<\/li>\n<li><strong>Computed tomography (CT) scan:<\/strong> The donut-shaped <a href=\"https:\/\/www.pockethealth.com\/2024\/07\/29\/ct-scan-preparation\/\">CT scan<\/a> machine uses cross-sectional X-rays to create detailed images of internal organs and structures. While there is exposure to low-dose radiation, it is considered safe for most patients.<\/li>\n<\/ul>\n<h3>Biopsy<\/h3>\n<p>This procedure involves taking a small tissue sample from the patient\u2019s kidney to assess it for damage in a laboratory. It may be performed as a needle biopsy, where an ultrasound is used to guide the doctor as they insert the needle through the skin and into the kidney, with numbing and relaxation medications to make the patient more comfortable. In some cases, a laparoscopic biopsy may be needed, where the doctor surgically removes a tiny tissue sample using a thin, lighted tube with a camera. This procedure is performed under anesthesia.<\/p>\n<div id=\"attachment_12676\" style=\"width: 1034px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-12676\" class=\"wp-image-12676 size-large\" src=\"https:\/\/www.pockethealth.com\/wp-content\/uploads\/2025\/03\/kidney-ultrasound-scan-min-1024x576.jpg\" alt=\"KIDNEY ULTRASOUND\" width=\"1024\" height=\"576\" srcset=\"https:\/\/www.pockethealth.com\/wp-content\/uploads\/2025\/03\/kidney-ultrasound-scan-min-1024x576.jpg 1024w, https:\/\/www.pockethealth.com\/wp-content\/uploads\/2025\/03\/kidney-ultrasound-scan-min-300x169.jpg 300w, https:\/\/www.pockethealth.com\/wp-content\/uploads\/2025\/03\/kidney-ultrasound-scan-min-768x432.jpg 768w, https:\/\/www.pockethealth.com\/wp-content\/uploads\/2025\/03\/kidney-ultrasound-scan-min-1536x864.jpg 1536w, https:\/\/www.pockethealth.com\/wp-content\/uploads\/2025\/03\/kidney-ultrasound-scan-min.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><p id=\"caption-attachment-12676\" class=\"wp-caption-text\"><em>Kidney ultrasound<\/em><\/p><\/div>\n<h2>Health impacts of stage 3 chronic kidney disease<\/h2>\n<p>Stage 3 kidney disease means the patient has kidney damage, but the kidneys still function well enough that a kidney transplant or <a href=\"https:\/\/www.kidney.org\/kidney-topics\/dialysis\" target=\"_blank\" rel=\"noopener\">dialysis<\/a>\u2014medical treatments used to remove excess fluid and waste from the blood\u2014are not yet needed.<\/p>\n<p>Complications can begin in stage 3 CKD, but many patients do not experience them.

It is important to follow the doctor\u2019s recommendations, such as possibly having regular screenings, to monitor for any changes.<\/p>\n<p>&nbsp;<\/p>\n<h2>How is stage 3 chronic kidney disease treated?<\/h2>\n<p>Much of the treatment for stage 3 CKD depends on the condition that caused it in the first place. Often, treating this condition can help reduce further damage to the kidneys. Specific treatment plans will vary depending on the patient\u2019s medical history and their provider\u2019s recommendations. Common treatments include:<\/p>\n<ul>\n<li><strong>Supplements for bone health:<\/strong> Vitamin D and calcium are possible supplements to maintain bone health.<\/li>\n<li><strong>Medications for diabetes:<\/strong> If CKD was caused by diabetes, treating this disease may help prevent further damage.<\/li>\n<li><strong>Diuretics:<\/strong> To combat swelling and water retention, these medications help the body eliminate excess water and salt.<\/li>\n<li><strong>Blood pressure medications:<\/strong> Reducing high blood pressure can help slow or reduce kidney damage.<\/li>\n<li><strong>Medications for kidney function:<\/strong> Examples include SGLT2 inhibitors, which help protect the kidneys and reduce blood sugar.<\/li>\n<li><strong>Possible lifestyle changes:<\/strong> Some patients may benefit from lifestyle adjustments, such as a specific diet or increased physical activity.<\/li>\n<li><strong>A possible change in previous medications:<\/strong> Some unrelated medications may worsen chronic kidney disease, in which case the physician may recommend alternatives.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Getting your results<\/h2>\n<p>Turnaround times for imaging results can vary widely depending on the facility and your doctor\u2019s availability.

Stage 3 is an especially important time to take steps to reduce progression, as this tends to be when kidneys start to experience more problems. Patients should ask their doctor for recommendations.<\/p>\n<h3>Can you reverse stage 3 chronic kidney disease?<\/h3>\n<p>While kidney damage cannot be reversed, its progression can often be slowed with medical intervention and lifestyle changes. For patients who may progress to the advanced stages of the disease, treatment options include dialysis or a <a href=\"https:\/\/www.kidney.org\/kidney-topics\/kidney-transplant\" target=\"_blank\" rel=\"noopener\">kidney transplant<\/a>. However, for many patients, following their doctor\u2019s treatment guidelines can significantly delay or even prevent progression.<\/p>\n<h3>How are diabetes and chronic kidney disease related?<\/h3>\n<p>Diabetes is the most common cause of chronic kidney disease, accounting for up to <a href=\"https:\/\/www.kidney.org\/diabetes-and-chronic-kidney-disease\" target=\"_blank\" rel=\"noopener\">44% of new CKD cases<\/a>. It occurs when the body has high blood sugar levels due to insufficient insulin production or the ineffective use of insulin (a hormone that regulates blood sugar levels). Diabetes has multiple health effects, including damage to the blood vessels in the kidneys, which can lead to CKD. Managing diabetes through treatment can often help slow the progression of kidney disease.<\/p>\n<h3>Can chronic kidney disease be prevented?<\/h3>\n<p>CKD prevention is not always possible, as it depends on the underlying disease or condition causing the kidney damage. However, for many patients, significant preventative measures can be taken, such as lifestyle changes or medical management of other health issues. It may be a good idea to discuss these preventive strategies with your healthcare provider to see which specific recommendations may apply.<\/p>\n<p>&nbsp;<\/p>\n<h2>Take control of your health journey<\/h2>\n<p><a href=\"https:\/\/www.pockethealth.com\/\">PocketHealth<\/a> makes it simple to keep track of your kidney scans.
