Type 2 diabetes: Three signs of high blood sugar that can lead to 'irreversible damage'

Type 2 diabetes stems from a dysfunction in the way the body produces the hormone insulin. One of the primary roles of insulin is to regulate blood sugar – the main type of sugar found in blood. Poor insulin production therefore raises the risk of blood sugar levels running roughshod over the body, causing untold complications.
According to Doctor Sumera Shahaney, GP and Head of Clinical Operations Operations at Thriva, there are three telltale signs of blood sugar that can lead to permanent damage if left untreated.
For starters, consistently high blood sugar levels can increase the risk of retinopathy, warned Doctor Shahaney.
Retinopathy is a complication of diabetes caused by high blood sugar levels damaging the back of the eye (retina).
According to Doctor Shahaney, the hallmark symptom of retinopathy is vision loss.
