If you already know you have high blood sugar, prediabetes or type 2 diabetes, improving your blood sugar control is something I would absolutely prioritise for your overall health – and that includes your eyes.
But what if your blood sugar is “normal”?
This is where it gets interesting.
Long before blood sugar becomes high enough for a diagnosis of prediabetes, your body may already be struggling to manage it.
Insulin is the hormone that helps move glucose out of your blood and into your cells. As we become more insulin resistant, the body can compensate by producing more insulin. For a while, that extra insulin may do a pretty good job of keeping your blood sugar looking normal.
So a “normal” blood glucose or HbA1c doesn’t always mean everything is working perfectly behind the scenes.
Over time, the body may struggle to compensate and blood sugar starts to rise – which is when prediabetes and eventually type 2 diabetes can develop.
Why does this matter if you have AMD?
Because the health of our eyes is closely connected to our overall metabolic health. We can’t say that insulin resistance directly causes AMD, but poor metabolic health is associated with AMD.
If you have AMD, the time to look after your blood sugar is now – whether your numbers are normal or not.
