Kidney Health and Kidney Care

Overview

The kidneys are vital organs that play a crucial role in maintaining overall health by filtering blood, regulating electrolytes, and maintaining bodily balance. Located in the lower back, each kidney is approximately the size of a clenched fist and performs essential functions that keep our bodies operating efficiently. Understanding kidney health and proper care is essential for preventing kidney disease and maintaining overall well-being.

Understanding Kidney Function

What Kidneys Do

  • Filter 110-140 liters of blood daily removing waste and excess fluid
  • Remove excess fluid and waste products from the body
  • Maintain electrolyte balance (sodium, potassium, phosphorus)
  • Regulate blood pressure through fluid and hormone control
  • Produce essential hormones for various bodily functions

Hormone Production Functions

Key Hormones Produced

  • Hormones for blood pressure regulation (renin)
  • Hormones for bone health maintenance (calcitriol - active vitamin D)
  • Hormones for anemia prevention (erythropoietin - stimulates red blood cell production)

Location and Structure

  • Located in lower back on either side of spine
  • Bean-shaped organs about the size of a clenched fist
  • Protected by ribcage and surrounded by fat and muscle
  • Connected to bladder via ureters for waste elimination

Kidney Disease in Singapore

Alarming Statistics

  • 4.7 people diagnosed daily with kidney disease
  • “Two in three cases of kidney failure are caused by poorly controlled diabetes”
  • Rising prevalence due to lifestyle factors
  • Significant healthcare burden requiring long-term management

Impact on Health System

  • Increasing need for dialysis treatment
  • Rising healthcare costs associated with kidney disease
  • Quality of life significantly affected
  • Need for kidney transplants in advanced cases

Risk Factors for Kidney Disease

Controllable Risk Factors

Lifestyle Factors

  • Smoking - damages blood vessels in kidneys
  • Obesity - increases risk of diabetes and high blood pressure
  • Excessive painkiller use - can damage kidneys over time
  • Poor dietary habits - high salt, processed foods

Medical Conditions

  • Uncontrolled blood pressure - damages kidney blood vessels
  • Poorly controlled diabetes - leading cause of kidney failure
  • High cholesterol - affects kidney blood flow
  • Cardiovascular disease - shared risk factors

Non-Controllable Risk Factors

  • Family history of kidney disease
  • Age - kidney function naturally declines
  • Genetic predisposition
  • Ethnicity - some groups at higher risk

Symptoms of Kidney Problems

Early Warning Signs

  • Changes in urination (frequency, color, amount)
  • Swelling in feet, ankles, hands, or face
  • Fatigue and weakness
  • Shortness of breath
  • Nausea and vomiting
  • Back pain in kidney area

Advanced Symptoms

  • Severe fluid retention
  • High blood pressure

  • Annual blood and urine tests for kidney function
  • Weight monitoring for fluid retention

Screening and Early Detection

Who Should Be Screened

  • Family history of kidney disease
  • Diabetes or pre-diabetes
  • High blood pressure
  • Cardiovascular disease
  • Age over 60
  • Certain ethnic backgrounds with higher kidney disease risk

Screening Tests

Blood Tests

  • Serum creatinine to calculate kidney function (GFR)
  • Blood urea nitrogen (BUN)
  • Electrolyte levels

Urine Tests

  • Proteinuria (protein in urine)
  • Hematuria (blood in urine)
  • Urinalysis for various abnormalities

When to Consult Healthcare Professionals

Routine Consultation

  • Family history of kidney disease
  • Presence of risk factors for kidney disease
  • Annual health check-ups including kidney function
