Kidney health is an essential part of overall well-being, although it is often overlooked until symptoms appear. The kidneys help remove waste and excess fluids from the body; when their function is affected, complications may arise and require timely medical evaluation.
In many cases, kidney disease can progress silently. That is why knowing the risk factors, identifying warning signs, and having preventive checkups can make an important difference in diagnosis and treatment.
Why is it important to take care of your kidneys?
The kidneys perform essential functions in the body. In addition to filtering the blood, they help maintain the balance of fluids, salts, and minerals. When they do not function properly, the body may begin to accumulate substances that should normally be eliminated.
The challenge is that, in early stages, kidney problems may not cause clear symptoms. Many people discover they have kidney damage only after blood or urine tests are performed for another reason.
Risk factors for kidney disease
Some people have a higher risk of developing kidney disease, especially if they live with chronic conditions that require medical follow-up.
The main risk factors include:
- Diabetes.
- High blood pressure.
- Cardiovascular disease.
- Family history of kidney disease.
- Obesity.
- Frequent self-medication, especially with some painkillers or anti-inflammatory medications.
- Advanced age.
- History of frequent urinary tract infections or obstructive problems.
In Mexico, public health documents recognize type 2 diabetes and high blood pressure as frequent causes of chronic kidney disease.
Warning signs that should not be ignored
Although kidney disease can be silent at first, there are some symptoms that should be addressed, especially if they are persistent or if the person already has risk factors.
Some warning signs may include:
- Changes in the frequency or amount of urine.
- Foamy, bloody, or unusually colored urine.
- Swelling in the feet, ankles, legs, hands, or face.
- Constant fatigue without an apparent cause.
- Nausea, loss of appetite, or general discomfort.
- Blood pressure that is difficult to control.
- Pain in the lower back or side.
- Persistent itching or very dry skin.
- Difficulty breathing when fluid retention is present.
These symptoms do not always mean kidney disease, but they are a reason to seek medical evaluation, especially when they appear along with diabetes, high blood pressure, or family history.
What tests help evaluate kidney function?
Kidney health can be evaluated through simple tests indicated by a physician. Among the most commonly used are blood tests to estimate kidney function and urine tests to detect the presence of protein or albumin.
Some studies that the specialist may request include:
- Blood creatinine.
- Estimated glomerular filtration rate.
- General urine test.
- Urine albumin-creatinine ratio.
- Kidney ultrasound, if medically indicated.
- Additional studies depending on the patient’s medical history.
Timely detection allows for follow-up, control of risk factors, and medical decision-making before kidney damage progresses.
When should you see a nephrologist?
A nephrologist is the medical specialist in the diagnosis, follow-up, and treatment of kidney diseases. It is recommended to see this specialist when there is an abnormality in kidney function tests, protein in the urine, blood pressure that is difficult to control, or a history of diabetes and high blood pressure with suspected kidney damage.
It is also important to seek evaluation if there is persistent swelling, significant changes in urine, repeated urinary tract infections, frequent kidney stones, or if a primary care physician recommends a specialized review.
Kidney prevention: small habits that can help
Taking care of the kidneys does not mean waiting until symptoms appear. Kidney prevention begins with daily habits and regular checkups, especially in people with risk factors.
Some general recommendations include:
- Keeping blood pressure under control.
- Properly monitoring diabetes.
- Avoiding self-medication.
- Drinking water according to each person’s needs and medical indications.
- Reducing excessive consumption of salt and ultra-processed foods.
- Engaging in regular physical activity.
- Attending preventive medical checkups.
- Consulting a physician before taking supplements or frequently used medications.
These recommendations do not replace medical evaluation, since each patient may need specific indications according to their age, medical history, and health status.
