Chronic kidney disease, often called CKD, is becoming a major health problem around the world. In the United States alone, more than 35 million adults are living with the condition, but many do not know they have it.
Kidney disease often develops quietly over many years without causing obvious symptoms. By the time people begin to feel unwell, the kidneys may already have suffered serious damage. This is why doctors say that prevention and early detection are the best ways to protect kidney health.
The kidneys are two bean-shaped organs located on either side of the lower back. Although they are only about the size of a fist, they perform many important jobs every day.
They remove waste products and extra water from the blood, help control blood pressure, balance minerals such as sodium and potassium, produce hormones that help make red blood cells, and keep bones healthy. When the kidneys stop working properly, waste and fluid build up inside the body.
Over time, this can increase the risk of heart disease, stroke, anemia, weak bones, and eventually kidney failure. People with end-stage kidney disease usually need regular dialysis or a kidney transplant to stay alive.
Dr. Vasil Peev, a kidney specialist at Rush, says that while many forms of kidney disease can be treated, only a small number can be completely cured. For this reason, finding the disease early and preventing further damage are extremely important.
One of the first steps is to know your personal risk. Kidney disease is more common in people with diabetes, high blood pressure, obesity, heart disease, a family history of kidney disease, and adults over the age of 60.
Because symptoms may not appear until the disease is advanced, regular health check-ups are essential. Your doctor may recommend simple blood and urine tests that can detect kidney disease long before symptoms develop.
Eating a healthy diet is another important way to protect your kidneys. A diet rich in fruits, vegetables, whole grains, and other healthy foods can help control blood pressure, blood sugar, and body weight.
Reducing salt is especially important because too much sodium can raise blood pressure and place extra stress on the kidneys. Limiting sugary foods and highly processed foods can also lower the risk of diabetes and obesity, which are two major causes of kidney disease.
Regular physical activity also supports kidney health. Experts recommend at least 30 minutes of moderate exercise on most days of the week. Walking, cycling, swimming, and jogging are all good choices. Exercise helps control weight, lowers blood pressure, improves blood sugar levels, and keeps the heart healthy, all of which reduce the risk of kidney damage.
Staying well hydrated is equally important. Drinking enough water helps the kidneys remove waste products from the body. Dehydration reduces blood flow to the kidneys and may increase the risk of injury. While individual needs vary, many healthy adults benefit from drinking enough water throughout the day unless their doctor has advised them to limit fluids.
Managing diabetes, high blood pressure, and high cholesterol is one of the most effective ways to prevent kidney disease. Diabetes and high blood pressure are the leading causes of kidney failure.
Keeping blood sugar and blood pressure under good control can greatly reduce the risk of long-term kidney damage. Losing excess weight, if needed, can also improve these conditions and lower the risk even further.
Another important tip is to avoid overusing common pain medicines known as nonsteroidal anti-inflammatory drugs, or NSAIDs. These include medicines containing ibuprofen and aspirin.
Although they are widely available without a prescription, taking them too often or for long periods can damage the kidneys, especially in people who already have reduced kidney function. If pain or fever lasts longer than recommended, it is best to seek medical advice instead of continuing these medicines.
Limiting alcohol can also help protect kidney health. Heavy drinking can damage the kidneys and increase the risk of kidney disease. Drinking in moderation is generally considered safer for most healthy adults.
Finally, quitting smoking is one of the best decisions for your kidneys and your overall health. Smoking reduces blood flow to the kidneys, makes high blood pressure harder to control, and increases the risk of kidney disease. Studies have shown that people who stop smoking often experience a slower decline in kidney function than those who continue smoking.
Looking after your kidneys does not usually require major changes overnight. Small healthy habits practiced every day can make a big difference over time.
Regular check-ups, healthy eating, exercise, staying hydrated, managing chronic health conditions, using medicines wisely, limiting alcohol, and avoiding smoking can all help keep your kidneys working well for many years.
