E71.30
Disorder of fatty-acid metabolism, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Disorders of fatty-acid metabolism refer to a group of conditions where the body has difficulty processing or breaking down fatty acids, which are vital sources of energy and building blocks for cells. The specific ICD-10 code E71.30 designates an unspecified disorder in this category, indicating that the exact type or cause of the disorder has not been clearly identified. Such conditions can affect various organs and systems, often leading to metabolic imbalances that may impact overall health. While some fatty-acid metabolism disorders are inherited, others may develop due to acquired factors. Recognizing the signs and understanding the underlying causes are essential for diagnosis and management.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting enzymes involved in fatty-acid oxidation Inherited metabolic disorders such as medium-chain acyl-CoA dehydrogenase deficiency (MCADD) Insufficient dietary intake of essential fatty acids or nutrients Liver dysfunction impairing fat metabolism Some medications or toxins that interfere with metabolic processes Other metabolic or systemic conditions impacting enzyme activity
Key Symptoms: Muscle weakness or fatigue, especially during physical activity Episodes of hypoglycemia (low blood sugar) Jaundice or yellowing of the skin and eyes Enlarged liver (hepatomegaly) Recurrent vomiting or feeding difficulties in infants Developmental delays or neurodevelopmental issues in children Unexplained weight loss or failure to thrive Episodic metabolic crises characterized by vomiting, lethargy, and coma
Diagnostic & Treatment
Diagnosis Path: Blood tests measuring levels of fatty acids, acylcarnitines, and organic acids Urine analysis to detect abnormal metabolites Enzymatic activity assays in blood or tissue samples Genetic testing to identify mutations associated with fatty-acid oxidation disorders Detailed family history to uncover inherited patterns Imaging studies such as liver ultrasound if organ involvement is suspected
Treatment Protocols: Dietary modifications to restrict long-chain fatty acids and ensure adequate carbohydrate intake Supplementation with medium-chain triglycerides (MCTs), which are easier to metabolize Regular monitoring of metabolic markers Prompt treatment during metabolic crises with intravenous glucose and supportive care Avoidance of fasting to prevent hypoglycemia and energy depletion In some cases, enzyme replacement or gene therapy may be considered as future options
