A UACR of 30 milligrams per gram or higher may indicate increased albumin leakage, although results should be interpreted by a healthcare professional and may need confirmation.
Importantly, kidney damage can sometimes be present even when eGFR remains relatively normal.
This is why both blood and urine tests are valuable.
3. Monitor Your Blood Pressure
High blood pressure is one of the leading risk factors for chronic kidney disease.
It can damage the small blood vessels inside the kidneys over time.
At the same time, damaged kidneys can contribute to higher blood pressure by affecting fluid balance and the regulation of hormones involved in blood pressure control.
This creates a potentially harmful cycle.
People with high blood pressure should monitor it regularly and follow their treatment plan.
If you have diabetes, cardiovascular disease, or a family history of kidney disease, ask your healthcare professional how frequently your kidney function should be checked.
4. Pay Attention to Changes in Urination
Although urine changes do not always indicate kidney disease, certain patterns deserve attention.
These include:
-
Blood in the urine.
-
Persistent foamy urine.
-
Unexplained changes in how frequently you urinate.
-
Repeated nighttime urination.
-
Noticeably reduced urine output.
-
Persistent swelling accompanied by changes in urination.
Foamy urine can sometimes occur because urine is released forcefully or is concentrated. However, persistent excessive foam may indicate protein in the urine and should be evaluated.
Visible blood in the urine should always be medically assessed, even if it occurs only once.
5. Recognize the Major Risk Factors
Some people are more likely to develop chronic kidney disease.
Important risk factors include:
Diabetes: Persistently elevated blood sugar can damage the kidneys' filtering structures.
High blood pressure: Long-term hypertension can damage kidney blood vessels.
Heart disease: Cardiovascular disease and kidney disease frequently occur together and share several risk factors.
Family history: Having close relatives with kidney disease may increase individual risk.
Older age: Kidney function can change with aging, although chronic kidney disease is not an inevitable part of getting older.
Certain medications: Frequent or prolonged use of some medications, particularly nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen, can harm kidney function in susceptible individuals.
People with these risk factors should discuss appropriate screening with their healthcare professional, even if they feel healthy.
6. Build Habits That Support Kidney Health
There is no single food or supplement that can guarantee protection against kidney disease.
However, several lifestyle habits can help reduce risk and support overall health.
Control blood pressure. Follow your prescribed treatment and monitor readings when recommended.
Manage blood sugar. If you have diabetes, maintaining good glucose control can help reduce the risk of kidney damage.
Reduce excessive sodium intake. Eating too much salt can contribute to high blood pressure and fluid retention.
Stay physically active. Regular movement supports cardiovascular health and helps maintain a healthy weight.
Avoid smoking. Smoking damages blood vessels and increases cardiovascular risk, which can also affect kidney health.
Use medications responsibly. Do not take pain relievers, supplements, or herbal products regularly without considering their potential effects on the kidneys.
Maintain a balanced diet. Include vegetables, fruits, whole grains, and appropriate sources of protein. People with established kidney disease may need individualized dietary adjustments.
Stay hydrated appropriately. Most healthy adults should drink enough fluids to avoid dehydration, but people with advanced kidney disease or heart failure may need specific fluid limits.
THE BOTTOM LINE: DO NOT IGNORE PERSISTENT CHANGES IN YOUR HANDS
Your hands may reveal clues about your general health, but they cannot diagnose kidney disease on their own.
Persistent swelling of the fingers may sometimes be related to fluid retention. Unusual itching and dryness can occur in advanced kidney disease. Nail discoloration, muscle cramps, and changes in skin color may also appear in certain people with impaired kidney function.
However, each of these symptoms has many possible explanations.
The most important thing is to look at the complete picture rather than focusing on one isolated sign.
If you notice persistent swelling, unexplained itching, unusual nail changes, or repeated muscle cramps, especially alongside fatigue, high blood pressure, changes in urination, or swelling in your legs and face, arrange a medical assessment.
Do not wait for severe symptoms before checking your kidney health if you have diabetes, hypertension, cardiovascular disease, or a family history of kidney problems.
Simple blood and urine tests can help identify kidney abnormalities before more obvious symptoms develop.
And remember: taking care of your kidneys does not begin when something feels wrong. It begins with regular health checks, sensible daily habits, and paying attention when your body shows changes that do not seem normal.
Sometimes, the most important warning sign is not a dramatic symptom. It is a small change that keeps happening and deserves to be investigated.
