Glucose-Galactose Malabsorption (GGM) is an autosomal recessive and rare disorder of intestinal transport of glucose and sodium-glucose cotransporter type (SGLT1).
Case Report
Our patient is a 32-day-old boy who was examined for severe diarrhea and acidosis and was treated with GGMdiagnosis. A number of laboratory tests were performed on this patient as well as positive test for reduced substance of stool and positive hydrogen breath test. On the other hand, the improvement of diarrhea with fasting and the initiation of a glucose and galactose free formula (fructose-basedformula [galactomin B-19]) was instructed. He was treated and followed with diagnosis of GGM.
In summary, careful clinical observation, laboratory tests, and the character of the external cues may provide indications of GGM.
