They are modest in size, 12 cm long by 6 cm wide, bean-shaped, and we often forget about their importance until they start giving us problems. Let's talk about them. Reindeer, two vital organs that work tirelessly to filter our blood, eliminate toxins, and maintain the balance of fluids and minerals in the body. When the kidneys don't function properly, we speak of kidney failure, a serious condition that can have serious repercussions on overall health.
Understanding the importance of the kidneys and learning to recognize the warning signs that indicate their malfunction is crucial for timely intervention and prevention of further damage. In this article, we'll guide you through kidney function, the types of kidney failure, the symptoms you shouldn't ignore, and how to Hub Medical Center can help you prevent and manage these conditions.
The kidneys: silent guardians of our health
The kidneys are extraordinary organs, located on the sides of the spinal column, just below the rib cage. Their main function is to filter approximately 180 liters of blood per day, removing waste products and excess fluid to produce urine. But their responsibilities go far beyond simple "cleaning":
- blood pressure regulation: produce hormones that help control blood pressure
- red blood cell production: secrete erythropoietin, a hormone that stimulates the bone marrow to produce red blood cells
- maintaining bone health: activate vitamin D, essential for calcium absorption and bone health
- regulation of water and salt balance: ensure that the body has the right amount of water, sodium, potassium and other minerals.
When the kidneys can no longer perform these vital functions efficiently, waste products build up in the blood, causing a series of Health problems.
What is renal failure and its forms (acute and chronic)
The kidney failure (or kidney dysfunction) occurs when the kidneys lose the ability to effectively filter waste products from the blood. There are two main forms:
- acute renal failure (ARF)It occurs when the kidneys suddenly stop working properly, usually due to a traumatic event, a serious infection, severe dehydration, or the use of certain medications. It is often reversible with prompt treatment. Symptoms tend to develop rapidly, over days or weeks.
- chronic kidney disease (CKD) or chronic kidney failureIt is a progressive condition in which the kidneys gradually lose function over months or years. Initially, symptoms may be mild or absent, making diagnosis delayed. If left untreated, it can progress to end-stage renal failure, requiring dialysis or a kidney transplant.
Understanding the difference is crucial, as the diagnostic and therapeutic approach varies radically between the two forms.
Symptoms not to be underestimated: signs that your kidneys are in trouble
The symptoms ofkidney failure They often appear only when kidney function is already significantly compromised. This is why it's crucial to recognize them and not ignore them:
- swelling (edema)One of the most common signs is swelling of the feet, ankles, legs, face, and hands. This is due to fluid buildup that the kidneys can no longer eliminate.
- decreased urine productionYou may notice that you urinate less frequently or produce a smaller amount of urine. In some cases, your urine may appear dark or foamy.
- persistent tiredness and weakness: the accumulation of toxins in the blood and the reduced production of erythropoietin (which causes anemia) can lead to a feeling of extreme tiredness, weakness and difficulty concentrating
- difficulty breathingFluid buildup in the lungs (pulmonary edema) or anemia can cause shortness of breath, even with minimal exertion.
- nausea, vomiting and loss of appetite: Toxins that build up in the blood can affect the digestive system
- skin itching: The buildup of waste products can irritate the skin, causing persistent and widespread itching.
- muscle cramps and restlessness in the legsElectrolyte imbalances (such as calcium and phosphorus) can cause cramps and restless leg syndrome
- headache and mental confusion: Toxin buildup can affect the brain.
If you notice one or more of these symptoms, especially if they persist, it is essential to consult a doctor immediately.
The main causes and risk factors
Several conditions can lead to kidney failure, both acute and chronic:
- diabetes mellitus: It is the most common cause of chronic kidney disease. High blood sugar levels damage the small blood vessels in the kidneys.
- high blood pressure (hypertension)Uncontrolled hypertension is the second most common cause of chronic kidney disease, damaging the kidney blood vessels.
- primary kidney diseases: conditions such as glomerulonephritis (inflammation of the kidney filters), polycystic kidney disease (cysts on the kidneys), and interstitial nephritis
- urinary tract obstructionKidney stones, an enlarged prostate in men, or tumors can block the flow of urine, causing pressure buildup and kidney damage.
- serious infections: sepsis or recurrent and untreated urinary tract infections
- drugs: some drugs (e.g. chronically taken NSAIDs, some antibiotics, contrast media) can be nephrotoxic, especially in high doses or in predisposed people
- severe dehydration: fluid deficiency that reduces blood flow to the kidneys
- autoimmune diseases: like lupus
- familiarity: the presence of family members with genetically transmitted kidney diseases.
Diagnosis and Management: An Essential Path
Early diagnosis is essential to prevent the progression of kidney damage. Your doctor may suspect a kidney problem based on your symptoms and medical history. Diagnostic tests include:
- blood testsCreatinine, urea and glomerular filtration rate (eGFR) are the most important parameters for evaluating renal function.
- urine tests: to detect the presence of protein (proteinuria) or blood (hematuria), which indicate kidney damage
- renal ultrasound: to view the size, shape and presence of abnormalities in the kidneys
- renal biopsy: in some cases, to obtain a sample of kidney tissue for examination.
Management of kidney failure depends on the cause and its severity. It often includes monitoring of underlying diseases (diabetes, hypertension), changes in diet (reduction of sodium, protein, potassium and phosphorus depending on the phase), drugs to manage symptoms and, in advanced stages, the dialysis or kidney transplant.
