Had an eye test today and the optician thinks I have a cotton wool spot on my retina which she says can be a sign of diabetes. She suggested I see my GP and I've asked for an appointment.
However, I'm confused- I have annual blood tests due to hashimotos and my GP usual asks for everything not just thyroxine levels, so I've been being regularly tested for years and never had an issue. Last test was March 23 and my HbA1c was 33 mmol/mol which is bang in the middle of normal. Everything else also normal inc cholesterol.
I'm surprised as I thought diabetes type 2 usually crept up. Could I have gone from normal to diabetic within less than a year and with no indication of pre-diabetes or symptoms or change in lifestyle? Otherwise is there anything else the cotton wool spot could mean?
Would really appreciate any advice. Obviously the GP appointment is key but they tend to take a while for non urgent things.
