Hai, I am Ria from Toronto. I am new here. It is for my dad I am writing here. He is obese and Doc during his last check up has asked to control weight or else there would chances of getting things worse. He is under a treatment for weight loss ( http://www.harveybrooker.com/weight-loss-packages/ ) at Harvey Brooker in Toronto. I happen to read a blog last day in which it was written that their chances of vision loss for a person with diabetics. And my friend was telling me that obesity or weight can also be a reason for vision loss. Will it be the reason for vision loss? I am planning to take him for a check-up next week so as to make sure whether my dad diabetic or not. But before that, I want to clarify whether being obese is a reason for vision loss.
