[Hepatic glycogen storage diseases: Symptoms, management and associated mutations].

Glycogen storage diseases (GSD) are rare diseases derived from altered glycogen metabolism. This leads to glycogen storage in different organs such as muscle, kidney, and liver, resulting in a variety of clinical manifestations. GSD with liver involvement are classified into types I, III, IV, VI, and IX, depending on the enzymes affected.

[Fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPS)].

An increasing number of children and adults are currently suffering symptoms due to FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols) consumption. These carbohydrates are poorly digested in the human gastrointestinal tract, exerting an osmotic effect in the small intestine. In the colon, they become substrates to the microbiota.
