"WHAT HAPPENS TO YOUR KIDNEYS DURING INTERMITTENT FASTING"

Описание: WHAT HAPPENS TO YOUR KIDNEYS DURING INTERMITTENT FASTING
A Scientific & Motivational Explanation

📌 About This Video
Intermittent fasting is often discussed in terms of weight loss and metabolism, but its effects on the kidneys are rarely explained.
In this video, we explore what actually happens to your kidneys from hour zero onwards during intermittent fasting — using science, physiology, and clinical insight.
This lecture explains how fasting:
• Reduces metabolic overload on kidneys
• Improves sodium and water handling
• Supports cellular repair mechanisms like autophagy
• Protects kidney structure and function when practiced responsibly
This video is meant for patients, caregivers, health professionals, and anyone interested in preventive kidney health.

🧠 What You Will Learn in This Video
✅ Are kidneys harmed or helped by intermittent fasting?
✅ What happens in the kidneys during the first 4, 12, and 24 hours of fasting
✅ How insulin reduction changes kidney workload
✅ Why fasting improves sodium balance and blood pressure
✅ The role of kidneys in glucose production during fasting
✅ What happens to creatinine, urea, and electrolytes
✅ How autophagy protects kidney cells
✅ When fasting is beneficial — and when it is risky
✅ Who should avoid fasting or do it only under medical supervision

🧬 Kidneys Are More Than Filters
Kidneys are intelligent metabolic organs.
They constantly:
• Sense blood chemistry
• Regulate salt and water
• Control blood pressure
• Support glucose balance
• Protect their own cells
Intermittent fasting gives kidneys metabolic rest in a world of constant feeding.

⏱️ What Happens Hour by Hour
0–4 hours:
• Insulin falls
• Excess salt and water are released
• Mild increase in urine output
4–12 hours:
• Kidneys assist in glucose production
• Insulin sensitivity improves
• Metabolic flexibility increases
12–18 hours:
• Fat and ketones become major fuel
• Kidneys maintain acid–base balance
• Inflammation begins to reduce
18–24 hours:
• Autophagy and cellular repair activate
• Oxidative stress reduces
• Kidney cells function more efficiently

🧪 What About Creatinine, Urea & Electrolytes?
• Creatinine may appear slightly higher due to reduced plasma volume — kidney function remains stable
• Urea handling improves over time
• Sodium is initially excreted, then balanced
• Potassium and magnesium remain stable in healthy kidneys
👉 Lab values must always be interpreted in clinical context.

🛡️ Why Healthy Kidneys Benefit from Fasting
Intermittent fasting helps kidneys by:
• Reducing chronic insulin exposure
• Lowering hyperfiltration stress
• Improving sodium sensitivity
• Supporting mitochondrial health
This is especially helpful in:
• Prediabetes
• Early hypertension
• Obesity-related kidney stress
• Metabolic syndrome

⚠️ Who Needs Caution
Intermittent fasting should be avoided or strictly supervised in:
• Advanced chronic kidney disease (Stage 4–5)
• Acute kidney injury
• Eating disorders
• Pregnancy
• Patients on strong diuretics or certain medications
Fasting is a physiological tool, not a punishment.

💧 Hydration Is Essential
Fasting does not mean fluid restriction.
Water and non-caloric electrolytes are important to support kidney adaptation.

💡 Key Take-Home Message
Intermittent fasting does not make kidneys work harder.
It allows them to work smarter.
By restoring natural feeding–fasting rhythms, kidneys:
• Reduce unnecessary stress
• Activate repair pathways
• Return to their evolutionary design
When practiced responsibly, intermittent fasting supports kidney health, metabolism, and long-term resilience.
