When you eat excess sugar, the extra insulin in your bloodstream can affect your arteries, part of your body’s circulatory system.
It causes their walls to grow faster than normal and get tense, which adds stress to your heart and damages it over time.
This can lead to heart disease, heart attacks, and strokes.
How does sugar affect your blood vessels?
Researchers have gained fresh insights into how elevated glucose levels damage blood vessels. High glucose levels reduce the levels of the powerful vasodilator nitric oxide in blood vessels, a shortfall that increases the risk of high blood pressure and eventually narrows down the vessels.
Does sugar harden your arteries?
Numerous studies have shown that chronic high blood sugar levels (associated with uncontrolled diabetes and other conditions) lead to atherosclerosis, or hardening of the arteries, and are associated with heart disease and heart failure.
How does diabetes damage blood vessels and nerves?
As a metabolic disease, diabetes causes a cascade of problems, many linked to high blood levels of glucose and lipids. “Increased sugars and fats promote oxidative stress—the production of excessive amounts of oxygen-derived free radicals that can damage blood vessels,” according to Semenkovich.
How does sugar affect the heart rate?
While this is going on, the body interprets this significant rise in sugar and energy as the result of stress, and releases cortisol and epinephrine. These hormones cause the heart rate to increase, which will in turn cause blood pressure to rise, and may induce sweating.
