Low blood sugar, also known as hypoglycemia, occurs when the sugar levels in your blood drop to a point too low to be able to provide your body with energy. Diabetes is the most common cause of low blood sugar, but it isn’t the only cause. So, even if you don’t have diabetes, you should be aware of the symptoms of low blood sugar.
Mild hypoglycemia often begins as a feeling of hunger or nausea, or a combination of the two, that leaves you feeling weak, clammy or jittery. This can occur to varying degrees for simple reasons such as over exerting yourself in a workout or going too long without food. At a moderate level, hypoglycemia can blur a person’s vision, can cause them to have trouble walking and may cause feelings of fear, temper or confusion. At its most severe, hypoglycemia can result in seizures, coma or even death.
In addition to diabetes, hypoglycemia can be caused by alcohol abuse, problems with metabolism and complications with certain medications or a disease of the kidneys, liver or pancreas. If you feel any of the symptoms of low blood sugar drink some fruit juice or eat some hard candy to give a quick blast of sugar to your system. If it occurs more than once, see your doctor determine the cause of your low blood sugar.
