Hypoglycaemia occurs when there is an excessive decrease in the level of blood glucose.
The risk factors in diabetes, the cause of hypoglycaemia, may be too much insulin or intake of oral hypoglycaemic drugs, poor nutrition, especially of starches, delays in ingestion, excessive physical activity or a combination of these factors.
The body needs glucose, a form of sugar, to have enough energy. After eating, blood glucose is absorbed. If you eat more sugar than your body needs, the muscles and liver store glucose that they do not use. When blood sugar begins to fall, a hormone tells the liver to release glucose.
