Guest, we'd love to know what you think about the forum! Take the Diabetes Forum Survey 2025 »

Message: <blockquote data-quote="Deleted member 527103" data-source="post: 2392934">The way it was explained to me (albeit, probably a bit simplified) is ...When we have high blood sugars, our body does its best to get rid of the excess sugar. This is the reason why frequent urinating is a common symptom of diabetes. Our bodies find all sorts of ways to get rid of those excess carbs - tooth decay could be another symptom when our saliva because more sugary. We even secrete sugar through our tears. Sugary tears have a different refractive index to salty tears so our eyes adapt to focus through sugary tears. With type 2, the symptoms come on slowly and our eyes adapt slowly so we don't notice the change until we do something about our blood sugars. Then our tears start to loose the sugar and our eyes need to adapt again. This takes time and we can experience blurred vision during this optical adaption. This does not mean you should avoid opticians if you think you have other problems with your eyes. It means that it is not advisable to buy expensive glasses during the change as your prescription will not be valid for long. Some people find cheap ready readers help during this transition.</blockquote>
