If you are handling people who have previously had bariatric surgery, you should look out for visual impairment.
A Portuguese study conducted by Dr, Rui Azevedo Guerreiro, showed that 69% of bariatric surgery patients went on to suffer vitamin A deficiency 4 years post op, leading to eye problems.
The study does not explain why this happens other than many don’t take the vitamin supplements that they are encouraged to take.
