Inborn errors of metabolism are rare genetic (inherited) disorders in which the body cannot properly turn food into energy. The disorders are usually caused by defects in specific proteins (enzymes) that help break down (metabolize) parts of food.

Can metabolic disorders be cured?
The treatment approach for metabolic disorders depends on the specific disorder. Inborn errors of metabolism (inherited metabolic disorders) are often treated with nutritional counseling and support, periodic assessment, physical therapy, and other supportive care options.
How do you test for metabolic disorders?
Doctors diagnose metabolic disorders with screening tests. Blood tests and a physical exam are standard parts of the diagnosis process. With so many inherited metabolic disorders, each kind of testing or screening will be different.

Metabolic disorders can cause seizures through one of three ways: deficiency of substrates essential for cellular metabolism or membrane function, intracellular accumulation of toxic substances and alteration of intracellular osmolality .

How common are inborn error of metabolism?
Although any given inborn error of metabolism is very rare, taken as a group, inborn errors of metabolism occur in 1 in 2500 births.
When should you suspect inborn errors of metabolism?
When children exhibit persistent FTT that does not respond to increased energy intake through diet, primary care physicians should consider organic causes including inborn errors of metabolism (IEM).
How is inborn error of metabolism diagnosed?

Is lactose intolerance an inborn error of metabolism?
Inborn Errors of Metabolism
Lactose intolerance, also called lactase deficiency, is due to an insufficient level of lactase, which hydrolyzes lactose into glucose and galactose. Therefore, ingestion of milk and dairy products results in bloating, abdominal cramps, diarrhea, and related symptoms.
