People likely to get kidney disease are those with diabetes, high blood pressure, or a family history of kidney failure, as well as those who are older, obese, smokers, or have heart disease, a history of acute kidney injury, or are of Indigenous Australian descent, with certain ethnic backgrounds also facing higher risks. Underlying causes often involve damaged blood vessels from uncontrolled blood sugar or high blood pressure, and certain medications or infections can also play a role.
Factors that can raise your risk of chronic kidney disease include:
Early signs of kidney disease often involve subtle changes like foamy urine, increased nighttime urination, swelling (puffy eyes, ankles), persistent fatigue, loss of appetite, nausea, itching, and shortness of breath, though many symptoms only appear as kidney function declines. High blood pressure can also be both a cause and an early indicator, and some damage may only be detected through lab tests, even with no noticeable symptoms in the earliest stages (Stage 1).
What causes CKD?
You can check kidney function at home using at-home test kits for urine (detecting protein/albumin) or finger-prick blood tests (checking creatinine/eGFR), often with smartphone apps for analysis, or by monitoring symptoms like increased nighttime urination (nocturia), swelling, or changes in urine (blood, foam) and discussing results with a doctor, as home tests screen but don't replace professional diagnosis.
Three key early warning signs of kidney problems are changes in urination (more or less frequent, especially at night), foamy or bloody urine, and persistent swelling, particularly around the eyes, feet, or ankles, indicating fluid retention. Other common signs include persistent fatigue, nausea, itching, and loss of appetite, as toxins build up when kidneys aren't filtering effectively.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
Stress and uncontrolled reactions to stress can also lead to kidney damage. As the blood filtering units of your body, your kidneys are prone to problems with blood circulation and blood vessels. High blood pressure and high blood sugar can place an additional strain or burden on your kidneys.
Unfortunately, chronic kidney disease (CKD) often cannot be cured. But if you are in the early stages of a kidney disease, you may be able to make your kidneys last longer by taking certain steps.
Symptoms of kidney disease
Where do I feel kidney pain? You feel kidney pain near the middle of your back, just under your ribcage, on each side of your spine where your kidneys are. Your kidneys are part of the urinary tract, the organs that make and remove urine from the body.
When kidneys cannot remove waste from your body, a rash can develop. One rash that occurs in people who have end-stage kidney disease causes small, dome-shaped, and extremely itchy bumps. As these bumps clear, new ones can form. Sometimes, the small bumps join together to form rough, raised patches.
Chronic Kidney Disease
Approximately 12% of non-Hispanic White adults have CKD. About 14% of non-Hispanic Asian adults have CKD. Approximately 14% of Hispanic adults have CKD. CKD is most common among people ages 65 or older (34%), followed by people ages 45 to 64 (12%), and people ages 18 to 44 (6%).
Chronic kidney disease (CKD) is a long-term condition where the kidneys do not work as well as they should. It's a common condition often associated with getting older. It can affect anyone, but it's more common in people who are black or of south Asian origin.
Canned foods, some frozen foods, and most processed meats contain large amounts of salt. Snack foods such as chips and crackers are also high in salt. Table salt, some seasonings, ketchup, mustard, and certain sauces such as barbecue, soy, and teriyaki sauces are high in sodium.
Two easy tests help determine if you have kidney disease or not;
Carbonated Drinks
Carbonated drinks are a type of drink that can damage the kidneys and should be limited. These drinks, especially the dark-colored ones, contain high levels of phosphoric acid, which adds pressure on the kidneys in filtering blood.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, avoid smoking and excessive alcohol, manage blood pressure and sugar, limit over-the-counter pain relievers (like NSAIDs), and maintain a healthy weight to support overall kidney function.
8 Surprising Ways You May Be Hurting Your Kidneys
The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. Your bladder stores urine. Your kidneys, ureters, and bladder are part of your urinary tract.
To support kidney health, focus on plant-based foods like berries, cabbage, cauliflower, onions, garlic, and leafy greens, plus fatty fish (salmon, tuna), egg whites, and whole grains like buckwheat, while limiting salt, processed foods, and high-potassium options like orange juice, opting for water as your primary drink. A kidney-friendly diet emphasizes fresh, whole foods to help reduce inflammation and manage kidney function.
Top 10 Drugs That Cause Kidney Damage
Diabetes and high blood pressure are the most common causes of chronic kidney disease and kidney failure. Unmanaged diabetes can lead to high blood sugar levels (hyperglycemia). Consistently high blood sugar can damage your kidneys as well as other organs.
While a damaged kidney typically can't repair itself, the condition can be treated if caught early. Acute kidney failure can be reversed with prompt hospitalization, although the recovery process can take weeks to months and requires regular monitoring, diet modifications, and medications.
