Kidney Disorder
What is Kidney Disorder?
Kidney disorder is a general term for any condition that affects how well your kidneys work. Your kidneys are two bean-shaped organs that filter waste and extra fluid from your blood. They also help control blood pressure, make red blood cells, and keep your bones healthy. When kidneys are damaged or diseased, they cannot filter blood properly.
Waste products and fluids can build up in your body when your kidneys fail to do their job. This can lead to swelling, high blood pressure, and dangerous levels of waste in your bloodstream. Kidney disorders range from mild dysfunction to complete kidney failure. Early detection through blood testing helps catch problems before they become serious.
Many kidney disorders develop slowly over months or years. Chronic kidney disease is the most common form, affecting about 1 in 7 American adults. Other kidney disorders include acute kidney injury, kidney stones, and inherited conditions. The good news is that early intervention can slow or stop kidney damage in many cases.
Symptoms
- Swelling in your ankles, feet, or legs from fluid buildup
- Foamy or bubbly urine caused by excess protein
- Urinating more often, especially at night
- Fatigue and weakness that does not improve with rest
- Loss of appetite or nausea
- Trouble sleeping or concentrating
- Muscle cramps, particularly in your legs
- Dry, itchy skin that feels uncomfortable
- Puffiness around your eyes, especially in the morning
- High blood pressure that is hard to control
Many people with early kidney disease have no symptoms at all. Kidneys can lose up to 90% of their function before symptoms appear. This is why regular blood testing is so important for catching kidney problems early.

Causes and risk factors
Diabetes and high blood pressure cause about 2 out of 3 cases of kidney disease. High blood sugar from diabetes damages the tiny blood vessels in your kidneys over time. High blood pressure puts extra strain on the filtering units inside your kidneys. Other causes include autoimmune diseases, infections, kidney stones, and prolonged use of certain medications like NSAIDs. Some people inherit genetic conditions that affect kidney function from birth.
Risk factors for kidney disorders include being over age 60, having a family history of kidney disease, and being African American, Hispanic, or Native American. Smoking, obesity, and heart disease also increase your risk. Repeated urinary tract infections and exposure to certain toxins can damage your kidneys over time. Taking steps to manage diabetes and blood pressure is the most effective way to prevent kidney damage.
How it's diagnosed
Kidney disorders are diagnosed through blood tests, urine tests, and imaging studies. Blood tests measure waste products like creatinine and check for protein leakage through albumin levels. When your kidneys are healthy, they filter albumin and keep it in your bloodstream. Excessive albumin in urine indicates your kidneys are not filtering properly. Urine tests can also detect blood, protein, and signs of infection.
Rite Aid offers albumin testing as an add-on to help monitor your kidney health. Your doctor may also order imaging tests like ultrasound or CT scans to look at kidney structure. A kidney biopsy may be needed in some cases to determine the exact cause of kidney damage. Regular testing helps track kidney function over time and catch problems before they progress.
Treatment options
- Control blood sugar if you have diabetes through diet, exercise, and medication
- Manage blood pressure with lifestyle changes and blood pressure medications
- Limit protein intake to reduce strain on your kidneys
- Reduce salt to help control blood pressure and fluid retention
- Stay hydrated with water unless your doctor advises fluid restriction
- Avoid NSAIDs like ibuprofen that can damage kidneys
- Take ACE inhibitors or ARBs to protect kidney function
- Use diuretics to reduce swelling and fluid buildup
- Work with a dietitian to create a kidney-friendly eating plan
- Consider dialysis or kidney transplant for advanced kidney failure

Frequently asked questions
The first signs often include changes in urination like foamy urine or urinating more at night. You might notice swelling in your ankles or feet from fluid retention. Many people feel unusually tired or have trouble concentrating. However, early kidney disease often has no symptoms, which is why blood testing is so important.
Some kidney disorders can be reversed if caught very early and the underlying cause is treated. Acute kidney injury often improves with proper treatment. However, chronic kidney disease cannot usually be fully reversed. The goal is to slow progression and prevent further damage through medication, diet, and lifestyle changes.
Albumin is a protein that healthy kidneys keep in your bloodstream. When kidneys are damaged, they start leaking albumin into your urine. Testing for excessive albumin levels helps detect kidney damage early, often before other symptoms appear. This test is especially important for people with diabetes or high blood pressure.
Limit foods high in sodium like processed meats, canned soups, and salty snacks. Reduce phosphorus from dairy products, nuts, and cola drinks. Cut back on potassium-rich foods like bananas, oranges, and tomatoes if your levels are high. Your doctor or dietitian will give you specific guidance based on your kidney function and blood test results.
If you have diabetes or high blood pressure, get tested at least once a year. People with known kidney disease may need testing every 3 to 6 months. Those at high risk due to family history should discuss testing frequency with their doctor. Early detection through regular testing helps prevent serious complications.
Staying hydrated helps your kidneys function properly and can prevent kidney stones. However, people with advanced kidney disease may need to limit fluids to prevent dangerous buildup. Always ask your doctor about the right amount of water for your specific situation. Generally, 6 to 8 glasses daily works well for healthy kidneys.
NSAIDs like ibuprofen and naproxen can harm kidneys, especially with long-term use. Certain antibiotics, contrast dyes used in imaging tests, and some heartburn medications may also affect kidney function. Always tell your doctor about all medications and supplements you take. They can suggest safer alternatives if you have kidney problems.
Many people with early-stage kidney disease live normal, active lives with proper management. Following your treatment plan, eating a kidney-friendly diet, and staying active can slow disease progression. Regular monitoring through blood tests helps you and your doctor make adjustments as needed. Even advanced kidney disease can be managed with dialysis or transplant.
Chronic kidney disease itself usually does not cause pain. However, some kidney problems like kidney stones or infections can be very painful. You might feel discomfort from swelling or muscle cramps related to kidney disease. If you experience pain along with other symptoms, contact your doctor right away.
Acute kidney injury happens suddenly over hours or days, often due to infection, dehydration, or medication. It can often be reversed with quick treatment. Chronic kidney disease develops slowly over months or years and is usually permanent. Managing the underlying cause and slowing progression are the main treatment goals for chronic disease.
