Stage 1 kidney disease often has no obvious symptoms because kidneys are still functioning well, but doctors may find signs like protein or blood in urine, high blood pressure, or frequent UTIs during tests for other issues. Subtle signs that might appear, though usually in later stages, include fatigue, foot swelling, or changes in urination, but these are common in many conditions.
You might not know that you have kidney disease until the condition is advanced. Healthcare professionals can find kidney disease through blood and urine tests. These tests look for high levels of waste in the blood or unusual things in the urine, such as protein or tiny amounts of blood.
Living with stage 1 kidney disease
There is no cure for kidney disease, but it may be possible to stop its progress or at least slow down the damage. In many cases, the correct treatment and lifestyle changes can help keep a person and their kidneys healthier longer.
Chronic kidney disease (CKD and chronic renal disease) means that there's damage to your kidneys and they aren't working as well as they should. Your kidneys are like a filter in your body — filtering out wastes, toxins and extra water from your blood.
Treating stage 2 kidney disease
Include a variety of grains (especially whole grains), fresh fruits and vegetables. Change to a diet that is low in saturated fat and cholesterol and moderate in total fats. Limit intake of refined and processed foods high in sugar and sodium.
Think of Stage 3 CKD as the "middle stage" of kidney disease. Your kidneys are damaged, but you don't need dialysis or a kidney transplant. In this stage, it's important to monitor not just your kidney function but also the levels of albumin in your urine, measured by the urine albumin-to-creatinine ratio (uACR).
For someone around 60, stage 1 stage 2 kidney disease life expectancy will be approximately 15 years. That figure falls to 13 years, 8 years, and 6 years in the second, third, and fourth stages of kidney disease, respectively.
High levels of metabolic waste products in the blood can damage nerve cells in the brain, trunk, arms, and legs. Uric acid levels may increase, sometimes causing gout. Diseased kidneys cannot excrete excess salt and water. Salt and water retention can contribute to high blood pressure and heart failure.
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.
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.
Early stages of CKD
Kidney disease does not tend to cause symptoms when it's at an early stage. This is because the body is usually able to cope with a significant reduction in kidney function.
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.
It's possible to live for many years with kidney disease. If your doctor diagnoses the condition in the earliest stages, you can prevent further damage with medication and lifestyle changes. Your kidneys will never repair themselves, but appropriate care will prevent the condition from swiftly progressing.
Fatigue – Because the kidney cannot filter waste, toxins can build up in the body. These can cause fatigue or extreme tiredness. Dark urine – Some rare kidney diseases cause bleeding, but sometimes this blood can be hard to see with the naked eye. Urine with visible blood may look red, brown, or darker than usual.
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.
How to manage kidney disease by being active
Surprising Things That Can Hurt Your Kidneys
Special renal vitamins are usually prescribed to provide extra water soluble vitamins needed. Renal vitamins contain vitamins B1, B2, B6, B12, folic acid, niacin, pantothenic acid, biotin and a small dose of vitamin C.
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.
Symptoms of a kidney infection
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.
What can I do to keep my kidneys healthy?
People with certain kidney disorders (such as interstitial nephritis or kidney damage resulting from sickle cell anemia) may also urinate excessively because these disorders also decrease the amount of fluid reabsorbed by the kidneys. Rarely, urinary frequency is caused by spinal cord injury or disorder.
