A British teenager has permanent vision loss, hearing loss and weak bones after years of eating only selected types of junk food. The teen's doctors eventually diagnosed him with a relatively new defined eating disorder called Avoid restrictive eating disorder (ARFID) They reported on the case of teenagers this week in the Annals of Internal Medicine

The case is rare in developed countries with a ready supply of nutritious foods. Bristol teen doctors They were initially startled by its progressive symptoms, but they warn other doctors in their case that such damage from malnutrition is potentially reversible ̵

1; if caught early – and even people of normal weight can struggle with eating disorders.

A puzzling slump

The first clue from teens' troubles came when the boy was 14 years old. He appeared before his family doctor, who was complaining of fatigue. In addition to being described as a "slacker", the teenager was healthy and did not take any medication. Tests show that he had anemia that makes the red blood cells unusually large, as well as low levels of Vitamin B 12 . His doctor treated him with Vitamin B 12 injections and dietary advice.

But the teenager's condition worsened. Only a year later he returned to doctors with unexplained hearing loss. Shortly thereafter, he developed vision problems. Over the next two years his vision continues to deteriorate. By the age of 17, his visual acuity was 20/200 in both eyes, which means he would have to be 20 feet tall to see something that a normal vision person would see sharply 200 feet away.

Scanning does not detect lesions of his visual area nerves and genetic tests are negative for hereditary explanations for blindness. His blood tests were mostly normal except that his blood cells were still enlarged and he had elevated levels of homocysteine ​​and methylmalonic acid, all indicators of vitamin B deficiency 12 .

This directed the doctors to a nutritional problem. But the teenager had a body mass index within normal range, of medium height and weight. He told doctors that he did not drink alcohol, use drugs or use tobacco.

Confession

The crack in this case appeared when he finally admitted to eating foods with only certain textures from elementary school. His diet consisted of a daily order of fried potatoes from a local fish and chips shop, Pringles chips, white bread, processed ham and sausages. The shots of Vitamin B 12 that were prescribed to him on 14. They disappeared.

The metabolic study showed that there were low levels of copper and selenium, high levels of zinc, remarkably low levels of vitamin D, and low bone mineral density, doctors reported.

His doctors have finally diagnosed him with nutritional optic neuropathy, which is dysfunction of the optic nerve, when the nutrients necessary for the functioning of the nerve fibers are in short supply. It is a rare condition, especially in developed countries, but is sometimes found in people with alcohol addiction. Doctors also diagnose the teenager with ARFID.

Although many children can be described as brazen eaters, the problem rises to the level of an eating disorder when eating is "restricted to junk food and causes multiple nutritional deficiencies," doctors explain.

They treated the teen with nutritional supplements and referred him to mental health services to contact his ARFID. In their report, doctors warned doctors to watch out for ARFID, which, unlike other eating disorders such as anorexia, is not controlled by body weight or shape. "As with this patient, BMI is often normal," they write.

Although the teen's eyesight has stabilized, it has not improved. His vision loss is permanent. Doctors hope their report will help other people identify ARFID and nutritional optic neuropathy early before it has the chance of causing permanent damage again.

For parents of cheeky eaters who do not have a eating disorder, the American Academy of Pediatrics offers convenient tips for resolving eating problems early. (Spoiler: Your child's guilt and fear of eating are not recommended methods.) If you are concerned that your child has an eating disorder, talk to your doctor. Cognitive-behavioral therapy is a commonly used method that helps patients with ARFID establish a healthier diet.
