What are the most important functions of the kidneys?
- Excretion of waste products formed during metabolic processes in urine
- Regulation of fluid and electrolyte balance in the body
- Participation in blood pressure regulation
- Maintenance of blood acid-base balance
- Producing the active form of vitamin D and regulating calcium and phosphate metabolism
- Producing a hormone called erythropoietin, which is necessary for blood formation
When should you see a nephrologist?
- Changes in urine: If you notice changes in the color, amount, or smell of your urine, such as foamy urine, reddish-brown urine, painful urination, or frequent urge to urinate, especially at night.
- Swelling or fluid retention, especially in the legs or around the eyes in the morning: One reason for this may be that the kidneys are unable to remove excess fluid properly, which can lead to edema.
- Constant fatigue or weakness: If you feel constantly exhausted and normal rest does not help. This can be a symptom of many diseases, one of which is advanced chronic kidney disease.
- Diabetes or high blood pressure: If these diseases are not properly controlled, they can lead to chronic kidney disease in the long term, so it is important to have your kidney function checked regularly if you have these diseases.
- Worsening high blood pressure: In all newly diagnosed cases of high blood pressure, it is mandatory to check the first morning urine and kidney function, because in every 10–12 cases, kidney disease may be the underlying cause. If your already treated high blood pressure starts to worsen and does not respond well to standard treatments, kidney problems may also be the underlying cause.
- Kidney stones: If you have already had kidney stones, it is worth having regular check-ups to prevent new stones from forming.
- Family history: If there is a history of kidney disease in your family, it is advisable to have a screening test at least once a year.
- Pain in the back or lower back: If you experience pain in the kidney area or lower back, especially if it is crampy or dull rather than sharp and stabbing, or if it is related to urination.

További információk
Chronic kidney disease (CKD) is a slowly developing condition in which the filtering function of the kidneys gradually declines. The disease may remain asymptomatic for a long time, so regular laboratory tests are necessary for early detection.
Causes of development:
- High blood pressure,
- Diabetes,
- Kidney tissue inflammation due to primary or immunological systemic disease
- Kidney stones, urinary tract obstructions,
- Hereditary kidney diseases.
What are the symptoms of chronic kidney disease?
- Fatigue, weakness
- Water retention (edema)
- High blood pressure
- Pale skin, anemia
- Difficulty concentrating, nausea in the late stages
Without treatment, chronic kidney disease can lead to end-stage renal failure, requiring dialysis or a kidney transplant. With early detection, the process can be slowed down and complications prevented!
The role of high blood pressure in kidney damage
High blood pressure and kidney failure exacerbate each other: persistently elevated blood pressure damages the small blood vessels in the kidneys, while deteriorating kidney function further raises blood pressure. Persistent blood pressure above 135/85 mmHg can damage the kidneys! The strain on the kidneys leads to gradual tissue destruction, which impairs the excretion of toxins. The kidneys also influence blood pressure by regulating salt and water balance, which is why even mild kidney damage puts strain on the cardiovascular system.
Diabetes and kidney damage
Type 2 diabetes, a very significant widespread disease, develops over many years, often without symptoms – it is often only recognized when it has already caused complications, such as kidney damage. Approximately 30% of diabetics develop some degree of kidney damage. Over a period of 10–20 years, persistently high blood sugar levels can cause proteinuria and then kidney failure. Type 2 diabetes is often accompanied by high blood pressure, elevated blood lipid levels, and abdominal obesity, which together accelerate atherosclerosis and kidney damage.
