High blood sugar levels impact several organs of the body including the heart, kidneys and eyes. A recent study published in the Journal of the American College of Cardiology observed the link between HbA 1c (a three-month average of blood sugar levels) and atherosclerosis (plaque build-up along the arteries of the heart) in people who did not have Diabetes. .The study observed 3973 people aged 40-54 years and their blood sugar levels were measured. The study found that people who had prediabetes(a condition where blood sugar levels are increased but not high enough to be termed as Diabetes) had a high risk of developing atherosclerosis. People with prediabetes may develop a risk of developing Diabetes within 5 years. if not managed well. The study has concluded that early assessment and reduction of blood sugar levels may not only prevent the progression to Diabetes but also other complications.
