Fatty acid oxidation disorders are a group of genetic conditions that affect the body's ability to break down fatty acids for energy. When the body cannot properly oxidize fatty acids, it can lead to a buildup of fats in the liver and other tissues, causing various health issues. These disorders can result in symptoms like low blood sugar, muscle weakness, and heart problems, especially during periods of fasting or illness. Diagnosis typically involves blood tests and genetic testing to identify specific enzyme deficiencies. Treatment often includes dietary management, such as avoiding fasting and consuming a high-carbohydrate, low-fat diet, to help prevent complications associated with these disorders.
