Yes, kidney problems can absolutely cause dizzy spells, often due to anemia (lack of red blood cells from reduced erythropoietin), toxin buildup affecting the brain, or complications like low blood pressure from infection, all leading to reduced oxygen or blood flow to the brain, resulting in fatigue, lightheadedness, and dizziness.
Dizziness and Trouble Concentrating
Anemia that is the result of kidney failure means that your brain is not getting enough oxygen, which can lead to memory problems, trouble with concentration, and dizziness.
While early kidney disease often has few signs, three key early warning signs to watch for are changes in urination (more/less frequent, foamy, or bloody), persistent fatigue, and swelling in hands, feet, or ankles, all pointing to the kidneys struggling to filter waste and excess fluid. These symptoms, along with others like itchy skin, poor appetite, or trouble concentrating, signal a need to see a doctor for proper testing.
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. (pee). You may feel kidney pain on one or both sides of your back.
Complications of acute kidney injury may include: Fluid buildup. A buildup of fluid in your lungs can cause shortness of breath. Chest pain.
Nausea and vomiting, muscle cramps, loss of appetite, swelling via feet and ankles, dry, itchy skin, shortness of breath, trouble sleeping, urinating either too much or too little. However, these are usually in the later stages, but they can also happen in other disorders.
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.
Symptoms can include:
Dull or sharp pain in the low back (often confused for kidney pain) is more likely due to a muscle pull, spinal issue, such as sciatica, or an injury. Kidney pain is usually felt higher up in the back and very rarely that low.
Kidney damage repair depends on the type: acute kidney injury (AKI) can often be reversed as the kidney heals itself, but chronic kidney disease (CKD) damage is generally irreversible, though its progression can be significantly slowed with lifestyle changes, medications (like SGLT2 inhibitors), and managing underlying conditions like diabetes and high blood pressure, with advanced stages requiring dialysis or transplant for survival.

Surprising Things That Can Hurt Your Kidneys
A severe decrease in kidney function can lead to a buildup of toxins and impurities in the blood. This can cause people to feel tired or weak and can make it hard to concentrate. Another complication of kidney disease is anemia, which can cause weakness and fatigue.
Chronic renal failure causes a variety of neurologic disorders affecting the central nervous system and the peripheral nervous system. These complications include diffuse encephalopathy, seizures, stroke, movement disorders, sleep alterations, polyneuropathy, mononeuropathies, and myopathy.
Stay Hydrated
Water helps flush out toxins and waste products from your body, allowing your kidneys to function more efficiently. Aim to drink at least 8-10 glasses of water daily, and consider increasing your intake if you're active or live in a hot climate.
Signs and Symptoms of Kidney Stones
Smaller kidney stones do not always cause symptoms and may pass without causing significant pain or damage. If symptoms do occur, they may include: dizziness or lightheadedness.
Symptoms of a kidney infection can include:
Kidney pain can have many causes. It may be a sign of an infection, injury or another health problem, such as kidney stones. Because of where your kidneys are in your body, kidney pain is also often confused with back pain.
Your kidneys are located just below the ribcage, with each kidney positioned on either side of your spine. Kidneys help to filter toxins and extra fluids from the body to ensure the rest of your body works normally. Common causes of kidney pain include UTIs, kidney infections, and kidney stones.
If your kidneys aren't working properly, you may notice one or more of the following signs:
Itching often happens on both sides of the body at the same time (for example, both arms or both legs). Itching is most common and severe in people with kidney failure,but those in the earlier stages of CKD may also notice milder itching.
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.
Chronic kidney failure
The best drink for kidney repair and overall health is plain water, as it helps flush toxins, but mineral water, unsweetened green tea, black coffee (in moderation), low-potassium juices (like unsweetened cranberry), and herbal teas (like ginger or mint) are also great for variety and added benefits, while sugary sodas, alcohol, and coconut water should generally be avoided. Always consult a doctor for personalized advice, especially with kidney disease.
