Blood sugar concentration, or glucose level, refers to the amount of glucose present in the blood of a human. Normally it stays within 3-7 mmol/l, but may vary greatly, particularly for diabetics. It can be measured with a relatively simple apparatus.
Alcohol interferes with the body's use of sugar in multiple ways. It inhibits the ability of certain amino acids to transform ingested sugar into glykogen, leaving the body less able to build adequate stores. Also, alcohol inhibits the hormone glukagon, responsible for releasing stored glykogen; thus, the body is less able to call forth the stored energy when needed. Especially diabetics are at risk of critically low blood sugar levels upon consumption of alcohol, risking seizures or even death as a result.
When a muscle is used, the energy is derived from breaking down glukose stored in the cells. However, the muscle has only a limited supply of stored glukose, and when this store is depleted, fat is broken down for energy instead. Thus, with prolonged or strenuous exercise there is a certain risk of hypoglycemia. To ensure an adequate supply of energy to the muscle, it is often advisable to eat before exercising, and possibly to eat further easily digested snacks while exersicing to replenish the sugar burned by the activity.
