E74.818
Other disorders of glucose transport
Clinical Classification Guidelines
Inclusion Terms
- (Familial) renal glycosuria
Medical Intelligence & Overview
Other disorders of glucose transport, classified under ICD-10 code E74.818, are a group of rare conditions affecting how the body moves glucose, a primary source of energy, into the body's cells. These disorders can impact the body's ability to regulate blood sugar levels, leading to various health complications. One notable example included in this category is familial renal glycosuria, a hereditary condition where the kidneys improperly excrete glucose into the urine despite normal blood glucose levels.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting glucose transporter proteins that facilitate glucose absorption in kidney and other tissues Inherited patterns, often autosomal dominant, leading to familial renal glycosuria Disruptions in specific glucose transporter genes, such as SGLT2 (sodium-glucose co-transporter 2) Secondary effects from other medical conditions or medications, although these are less common
Key Symptoms: Presence of glucose in urine without elevated blood sugar levels (glycosuria with normoglycemia) Often no symptoms; many cases are discovered incidentally during routine urine tests In some instances, mild dehydration or increased urination due to glucose loss Rarely, associated with symptoms of dehydration or electrolyte imbalance if significant glycosuria occurs
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of laboratory tests and medical history assessments. Key steps include:
Treatment Protocols: Most cases of familial renal glycosuria and other transporter disorders do not require treatment because they typically do not cause health problems. Management considerations include:
