(HealthDay News) — Bariatric surgery patients who don’t take prescribed vitamin and mineral supplements could put themselves at risk for vision problems, according to research published online November 26 in the Obesity Surgery.

The study authors reviewed the available research and found that nutrient deficiencies after bariatric surgery can lead to a wide range of eye conditions. The conditions include night blindness, ulcers, scarring of and changes to the cornea, involuntary eye movement, paralysis of the eye muscles, and dry eyes.

A lower intake of vitamins A, E, and B1 (thiamine) and copper are especially concerning because they help with the normal functioning of the eye and optic system, the researchers said. They found that vitamin A deficiency was most strongly linked to eye problems after weight-loss surgery.

“There is a risk that bariatric surgery patients, who do not take the vitamin and mineral supplements prescribed to them, could develop eye-related complications because of nutrient deficiencies,” study coauthor Rui Azevedo Guerreiro, MD, of the Lisbon Hospital Central in Portugal, said in a journal news release.
