Mitochondrial Myopathy is a group of disorders caused by problems in the mitochondria, the energy-producing structures in cells. These conditions can lead to muscle weakness, pain, and fatigue, as the muscles do not receive enough energy to function properly. Symptoms can vary widely among individuals and may also affect other systems in the body. The condition is often inherited and can be linked to mutations in mitochondrial DNA or nuclear DNA. Diagnosis typically involves genetic testing, muscle biopsies, and other assessments. Treatment focuses on managing symptoms and may include physical therapy and nutritional support to improve energy levels.
