Mitochondrial dysfunction occurs when the mitochondria, the energy-producing structures in cells, do not work properly. This can lead to reduced energy production, affecting various bodily functions and potentially causing symptoms like fatigue, muscle weakness, and organ dysfunction. Mitochondria are essential for converting nutrients into energy, and their impairment can disrupt normal cellular processes. Several factors can contribute to mitochondrial dysfunction, including genetic mutations, environmental toxins, and aging. Conditions such as diabetes, neurodegenerative diseases, and cardiovascular disorders have been linked to mitochondrial issues. Understanding and addressing these dysfunctions is crucial for improving health and managing related diseases.
