CSID vs. GSID

Is There Any Difference Between Congenital Sucrase-Isomaltase Deficiency and Genetic Sucrase-Isomaltase Deficiency?

The terms Congenital Sucrase-Isomaltase Deficiency (CSID) and Genetic Sucrase-Isomaltase Deficiency (GSID) are different names for the same condition.

So why does one disease have two names?

This is largely due to how old someone is when they are diagnosed. The word congenital means present at birth, and most congenital disorders are diagnosed when one is an infant or in early childhood. However, many patients with Sucrose Intolerance due to CSID are being diagnosed later in life, when they are in their teens or even when they are adults. Since the term congenital is associated with an early childhood diagnosis, some consider it more accurate, when it is diagnosed in older patients, to call the disorder GSID rather than CSID. The word genetic implies that the disorder may have been diagnosed at any time – in infancy, childhood, teenage years, or in adulthood. However, either name refers to the same disorder, which has likely been present since birth.
