For which condition is diet therapy considered the primary treatment?

Diet therapy is indeed a primary treatment for galactosemia, a genetic metabolic disorder that affects the body's ability to process galactose, a sugar found in milk and other dairy products. Individuals with galactosemia lack the enzyme necessary to convert galactose into glucose, which can lead to serious health problems if galactose accumulates in the body.

The standard treatment for galactosemia involves a strict dietary management that eliminates all sources of galactose, primarily through the removal of milk and dairy products from the diet. By adhering to this dietary restriction, individuals can avoid the complications associated with the condition and maintain better health outcomes.

In contrast, while diet management is also essential in conditions like diabetes or peptic ulcers, these conditions may require additional medical interventions and are not primarily treated through diet alone. For instance, peptic ulcers often require medications to reduce stomach acid and promote healing, and diabetes management can involve medications or insulin therapy alongside diet planning. Wilson's disease, another metabolic disorder, usually requires a combination of dietary modifications along with chelation therapy to manage copper levels in the body effectively. Thus, diet therapy stands out as the sole or primary mode of treatment specifically for galactosemia.
