What condition is characterized by the body's inability to tolerate galactose?

Galactosemia is a genetic disorder that specifically affects the body’s ability to metabolize galactose, a sugar found in milk and dairy products. This condition arises from a deficiency of enzymes responsible for breaking down galactose, leading to its accumulation in the body. High levels of galactose can result in severe complications, including liver damage, cataracts, and developmental delays if not managed through dietary restrictions.

The distinction among the conditions is crucial. For instance, breastfeeding intolerance refers to a broader category of feeding challenges that may arise from various factors, including sensitivity to certain components in breast milk but does not specifically point to the metabolic issue with galactose. Hypoglycemia involves low blood sugar levels and is not directly linked to the body's handling of galactose. Lactose intolerance, on the other hand, involves the inability to properly digest lactose, the sugar found in milk, due to a deficiency of the enzyme lactase, which is different from the metabolic dysfunction seen in galactosemia.

In summary, galactosemia is specifically marked by the body’s inability to process galactose, making it the condition directly related to the question prompt. Understanding this distinction is key in the context of lactation and metabolism when providing
