There is a causal relationship between high blood sugar levels and stroke. People with high blood sugar conditions such as diabetes and pre-diabetes are 2-4 times more likely to suffer a stroke. High blood sugar levels indicate that the body is unable to metabolize or break these sugars down. A hormone called insulin allows glucose to enter the cells. Insulin comes from the pancreas. When there is a problem with insulin production, it leads to problems with blood sugar levels. The glucose cannot enter the cells and give them energy. Instead, it remains in the blood.
As time passes, this accumulation of sugar in the blood can damage the blood vessels. These are the veins and arteries that the blood travels through during circulation. Fatty deposits and clots can form in the blood vessels due to the elevated blood sugar levels. When the fatty deposits become big enough, they can block a vein or artery. This deprives the brain of oxygen which results in a stroke. Alternatively, a clot may dislodge from the wall of a vein or artery and pass through the brain.
The consequences of a stroke can be paralysis or loss of specific brain and body functions. This can be temporary. In a lot of cases, however, it becomes permanent. This can have a profound effect on the sufferer’s quality of life.
If your doctor identifies that you are at risk of a stroke, it’s a good idea to test your blood sugar. It can be contributing to the rising chance of having a stroke. Risk factors for a stroke include high cholesterol levels, high blood pressure, and obesity in addition to high blood glucose levels. Other risk factors that can cause a stroke are smoking, drinking, and an unhealthy diet and lifestyle.
