Kidney

The kidneys are two bean-shaped organs, each about the size of a fist, located on either side of your spine, just below your rib cage. You’ve got one on the left and one on the right.

​

What Do Kidneys Do? (Their Role in the Body)

They’re basically the body’s natural filtration system. Here’s what they handle:

​

1. Filtering Blood
   They remove waste, toxins, and extra fluids from your blood, which become urine

2. Balancing Fluids & Electrolytes
   They help maintain the right balance of water, salts (like sodium and potassium), and acids in your blood.

3. Regulating Blood Pressure
   They release hormones (like renin) that help control blood pressure.

4. Producing Hormones

   • Erythropoietin: helps make red blood cells.

   • They also help activate vitamin D for bone health.

Common Kidney Diseases/Conditions

​

1. Chronic Kidney Disease (CKD)
   Slow loss of kidney function over time. Often caused by high blood pressure or diabetes.

2. Kidney Stones
   Hard deposits of minerals and salts that form in the kidneys—can be super painful!

3. Acute Kidney Injury (AKI)
   Sudden loss of kidney function, often due to severe infection, injury, or certain medications.

4. Glomerulonephritis
   Inflammation of the glomeruli (tiny filters in the kidney). Can be caused by infections or autoimmune diseases.

5. Polycystic Kidney Disease (PKD)
   A genetic disorder where fluid-filled cysts grow in the kidneys, causing them to enlarge and lose function.

6. Urinary Tract Infections (UTIs)
   If untreated, can spread to the kidneys (called pyelonephritis), which is more serious.

7. Kidney Cancer
   Less common, but serious if not caught early.

​

Great follow-up! Treating kidney diseases depends on what type of disease it is, how severe it is, and whether it’s acute (sudden) or chronic (long-term). I’ll break it down by type and mention common treatments/medications.

🔁 1. Chronic Kidney Disease (CKD)

Goal: Slow progression and manage symptoms.
Treatment:

• Control blood pressure:

  • ACE inhibitors (like Lisinopril)

  • ARBs (like Losartan)

• Manage diabetes:

  • Insulin or other blood sugar meds

  • Newer meds like SGLT2 inhibitors (e.g., Dapagliflozin, Empagliflozin) are kidney-friendly

• Dietary changes:

  • Low salt, low protein, controlled potassium/phosphorus

• Supplements:

  • Vitamin D, iron, erythropoietin-stimulating agents (like Epoetin alfa) for anemia

• Dialysis or transplant if kidneys fail completely

💥 2. Acute Kidney Injury (AKI)

Goal: Treat the cause and support kidneys
Treatment:

• Stop harmful meds (NSAIDs, some antibiotics, contrast dyes)

• Hydration or IV fluids if dehydrated

• Diuretics (like Furosemide) if fluid overloaded

• Treat underlying infections or causes

• Temporary dialysis if needed

🪨 3. Kidney Stones

Goal: Pain relief, pass the stone, prevent future ones
Treatment:

• Pain meds: NSAIDs (like Ibuprofen) or Opioids (for severe pain)

• Alpha-blockers: (e.g., Tamsulosin) to relax the ureters

• Hydration: lots of water to flush stones out

• Surgery or lithotripsy (sound waves) if stone is too big

🔥 4. Glomerulonephritis

Goal: Control inflammation and underlying cause
Treatment:

• Steroids (e.g., Prednisone)

• Immunosuppressants (e.g., Cyclophosphamide, Mycophenolate)

• Blood pressure meds

• Treat infections (if present)

🧬 5. Polycystic Kidney Disease (PKD)

Goal: Slow cyst growth and manage symptoms
Treatment:

• Blood pressure control

• Tolvaptan – a newer med that can slow cyst growth

• Pain management

• Dialysis/transplant if end-stage

🦠 6. Kidney Infection (Pyelonephritis)

Treatment:

• Antibiotics – usually Ciprofloxacin, Levofloxacin, or Ceftriaxone

• Pain and fever management

• Hospitalization if severe

This is how you can keep a health Kidney.

protecting your kidneys is all about lifestyle habits, hydration, and managing other health conditions. Here's a simple list of ways to keep your kidneys healthy:

✅ 1. Stay Hydrated (But Not Overhydrated)

• Drink enough water (usually 1.5 to 2 liters a day).

• More if you’re active, live in a hot climate, or sweat a lot.

• Avoid overdoing it—too much water can stress your kidneys too.

🥗 2. Eat a Kidney-Friendly Diet

• Limit salt – excess sodium raises blood pressure.

• Eat fresh fruits and veggies – but in balance, especially potassium-rich ones.

• Moderate protein intake – too much (like from high-meat diets) can strain kidneys.

• Limit processed foods – they’re often full of phosphorus and additives.

🩺 3. Control Your Blood Pressure

• High blood pressure is a top cause of kidney damage.

• Aim for a normal range (~120/80).

• Exercise, low-salt diet, and medication if needed.

💉 4. Manage Diabetes or Blood Sugar

• High blood sugar damages the kidney’s filtering units over time.

• Keep glucose in target range.

• Monitor it regularly if you’re diabetic or prediabetic.

🚭 5. Avoid Smoking and Excess Alcohol

• Smoking reduces blood flow to the kidneys.

• Alcohol in excess can dehydrate and raise blood pressure.

💊 6. Be Careful with Medications

• Avoid long-term or heavy use of NSAIDs (like ibuprofen, naproxen).

• Always follow dosage instructions.

• Check with a doctor if taking multiple meds regularly.

🧪 7. Get Regular Kidney Function Tests

• Especially if you have risk factors like:

  • High blood pressure

  • Diabetes

  • Family history of kidney disease

  • Age 60+

Tests like creatinine, GFR, and urine tests can spot issues early.

🏃‍♂️ 8. Stay Active

• Exercise helps keep weight, blood pressure, and sugar levels in check—all good for kidneys.

💧 Bonus Tip: Don’t hold in your pee too long.

• Doing it occasionally is fine, but constantly delaying bathroom trips can stress the urinary system.
