E74.31
Sucrase-isomaltase deficiency
Clinical Classification Guidelines
Medical Intelligence & Overview
Sucrase-isomaltase deficiency is a rare digestive disorder where the body lacks enough of the enzymes sucrase and isomaltase. These enzymes are essential for breaking down certain sugars found in foods, especially those containing sucrose (table sugar) and certain complex carbohydrates. Without sufficient enzymes, these sugars are not properly digested, which can lead to uncomfortable gastrointestinal symptoms and nutritional issues. This condition is categorized under E74.31 in the ICD-10 classification, helping healthcare providers identify and manage the disorder effectively.
Causes & Symptoms
Clinical Causes: Genetic mutations leading to the inherited form of the deficiency Acquired loss of enzyme activity due to intestinal damage from infections, inflammation, or surgery Rarely, as part of broader metabolic or digestive conditions
Key Symptoms: Diarrhea or loose stools after consuming foods high in sucrose or starch Bloating and abdominal distension Gas and flatulence Cramping or abdominal pain Nausea or vomiting in some cases Malnutrition and weight loss if the condition remains untreated Fatty, foul-smelling stools (steatorrhea)
Diagnostic & Treatment
Diagnosis Path: Diagnosis of sucrase-isomaltase deficiency generally involves a combination of clinical evaluation and specialized tests. These may include enzyme activity assays, breath tests that measure hydrogen production after ingestion of specific sugars, and genetic testing to identify mutations. Often, doctors may recommend a trial of dietary changes to observe symptom improvements, especially in mild cases. Confirming the diagnosis is crucial for proper management and to rule out other digestive disorders.
Treatment Protocols: Management of sucrase-isomaltase deficiency primarily focuses on dietary modifications and enzyme replacement. Typical approaches include:
