A 27-year-old woman, gravida 1 para 0, presents to the clinic for a routine evaluation. The patient is at 32-weeks gestational age and is feeling well. Family history is notable for a sibling who passed away from a carbohydrate metabolism disorder in early childhood. The patient cannot recall the details but states, “My sister would get very sick every time she drank juice or ate fruits.” The patient is concerned her unborn child may also have this condition.

Summary
Essential fructosuria is a benign autosomal recessive disorder in which there is a deficiency caused by a deficiency fructokinase enzyme. People with essential fructosuria don't metabolize fructose properly after ingesting a fructose-rich diet, causing it to be in urine, hence the name fructosuria.
