Lecture Notes: Impact of Exercise on Kidney Health

Presenters

• Michelle Krosmer
• Dr. Hashmi

Key Topics

Creatinine and Muscle Building

• Creatinine: A byproduct of muscle metabolism.
  • More muscle = More creatinine.
  • Used as an indirect measure of kidney function.
• Creatinine Levels: High levels in blood suggest poor kidney function, but increased levels can also be due to greater muscle mass.
• Conclusion: High creatinine doesn't necessarily mean worse kidney function; it could indicate increased muscle mass.

Creatine Supplements

• Creatine Intake: Converts to creatinine when consumed.
• Misinterpretation: Doctors may misinterpret elevated creatinine from supplements as kidney disease.
• Advice: Stop creatine supplements before blood tests to avoid misleading results.

Exercise and Kidney Disease

• People with Chronic Kidney Disease (CKD) are encouraged to exercise to the best of their ability.
  • Types of Exercise: Weightlifting, triathlons, etc.
• Considerations for CKD:
  • Acid clearance might be reduced, slowing recovery.
  • Monitor potassium shifts and lactic acid levels.
  • Build up to strenuous activities gradually.

General Advice

• Exercise Benefits: Enhances overall health and wellness.
• Creatinine Testing: Understand it's an indirect indicator; other measures like 24-hour urine collection can provide more accurate insights.

Conclusion

• Creatinine as a scare tactic should not deter exercise.
• Proper preparation and monitoring can allow individuals, even with CKD, to engage in various physical activities safely.

Final Remarks

• Stop creatine supplements before testing to ensure accurate kidney function assessments.
• Encourage questions and further engagement in future episodes.
