Heart disease can develop when blood sugar is above the normal range
Heart disease begins to develop when your blood sugar level is in the high-normal prediabetic range -above 100 to 110mg/dl. When glucose is within the 100 -125 mg/dl range -it can damage your blood vessels and increase your risk of a heart attack and stroke. According to Mary Elizebeth Patti, M.D., Harvard Medical School, Boston, – insulin leads to high levels of circulating insulin in the bloodstream that can damage blood vessel walls. This leads to the vessel walls getting thicker, and the opening becomes smaller.
High blood sugar wreaks havoc with the lining of blood vessels, the endothelium.
Think of the endothelium as the satin lining of a coat sleeve, if it gets snagged or ripped, your arm will not go through it smoothly, Similarly -blood doesn’t flow smoothly in adamaged artery, and it can actually do more damage. The endothelium becomes stickier, attracting blood clots, thus causing the blood vessels to constrict and not expand smoothly – which eventualy can lead to high blood pressure.
