Medication management with follow-up
Active treatment with regular monitoring by a healthcare provider is recommended.
Mitochondrial Supportive Medications
Additional mitochondrial support may include L-carnitine, B-vitamins, and other compounds that support cellular energy metabolism. Combination approaches are often used.
Additional treatment options
Cardiac and Neurological Monitoring
Regular monitoring of cardiac function, neurological status, and metabolic parameters to assess treatment response and detect disease progression or new organ involvement.
monitoringFatigue Management and Exercise Therapy
Carefully structured exercise program that respects energy limitations while maintaining muscle strength and function. Pacing strategies and graded exercise approaches are recommended.
