Does phenylketonuria still exist after the age of 20?

Patient's question:

Having urine odor, inattentiveness, and sometimes headaches

Doctor's answer:

Phenylketonuria is a type of congenital metabolic disease. This condition is inherited in an autosomal recessive manner.
Advice: It is absolutely not possible to have phenylketonuria. The presence of an ammonia-like odor indicates that the urine has been decomposed in the body, which is a sign of cystitis or urinary retention. A putrid, foul odor is common in cystitis and pyogenic pyelonephritis. A fecal odor is often present in urine from patients with vesicocolonic fistula. Some foods, such as garlic, onions, and certain medications, can also cause the urine to have a distinctive odor. In diabetic ketoacidosis, the urine may have an apple-like smell. It is recommended to visit a hospital for a checkup.
