What is Sucrase-Isomaltase Deficiency?
Sucrase-Isomaltase Deficiency is a rare disorder and is caused by mutations of the Sucrase-Isomaltase Gene. Low sucrose levels and reduced maltose activity can affect digestion of starches. This can cause symptoms such as diarrhea, abdominal pain, and abdominal bloating. This deficiency affects your ability to digest the sugars, sucrose, that is found in fruits and table sugar, and maltose, the sugar that is found in grains. This can lead to malnutrition and failure to thrive. Sucrase-Isomaltase Deficiency is usually treated by changing your diet to reduce the amount of sucrose and maltose.
