Weight Gain Effect On Blood Vessels.

Just an update while I’m writing a major post. I find it interesting how many people seem to think that being a little overweight is actually healthy, especially for women, and that it definitely do not impose any major risk to health. Well, it just isn’t so, and a recent study performed by researchers at the Mayo Clinic proved it. This study showed that putting on as little as four kilos of fat in the abdominal area (visceral fat) puts even young and healthy people at risk of developing endothelial dysfunction. Endothelium is the inner lining of blood vessels, which is responsible for the formation of new blood vessels, vasoconstriction and vasodilation, blood clotting, etc. Endothelial dysfunction is thought to be a major factor in the development of atherosclerosis and it contributes to high blood pressure, coronary artery disease and diabetes among other things.

In the above study, a number of healthy volunteers below 30 were tested for endothelial dysfunction by measuring the blood flow through their arm arteries. Afterwards, they were assigned to either gain weight or to maintain their healthy weight for 8 weeks. The weight gainers were asked to lose weight afterwards and were retested. Researchers found that those who gained abdominal fat had impaired regulation of blood flow through their arm arteries due to endothelial dysfunction. After volunteers lost weight their blood flow recovered.

This research clearly shows, that gaining even a few pounds during a holiday, while studying in college, etc. have cardiovascular implications, especially if the weight is gained in the abdomen. Furthermore, it shows that losing weight can reverse the condition and restore the normal blood flow. So it’s never too late to exercise!
