A blood sugar test is prescribed by doctors of various specialties. This routine examination requires proper preparation, as many factors, including alcohol consumption, reduce the accuracy of the results.

A key method in diagnosing disorders of carbohydrate metabolism is a blood sugar test. According to indications, this study is carried out on an empty stomach or 2 hours after eating.

The norm is considered to be fasting blood sugar in the range of 3, 3-5, 5 mM / l.

To eliminate the mistake for taking blood, you must properly prepare. An important point is considered the refusal of alcoholic beverages on the day of the study and the day before.

How alcohol affects blood sugar

Alcohol changes blood sugar levels quite dramatically. In a small amount, alcohol contributes to an increase in this indicator. Each gram of alcohol gives the body 7 kilocalories. The alcohol molecule is quickly involved in the metabolism and is easily converted into glucose by the action of liver enzymes.

On the other hand, alcoholic beverages can also lead to a drop in blood sugar concentration. This paradoxical reaction is associated with the effects of alcohol on liver function. Only 10% of the time during the day, a stable blood glucose concentration is formed due to carbohydrates entering the digestive tract. The rest of the time, it is the liver that creates new glucose from the body's own stores. Alcohol in large doses disrupts this process. Blood sugar can drop dramatically a few hours after drinking. This effect of alcohol on the liver can persist for 24-48 hours.

Why alcohol reduces the accuracy of your blood sugar test

Under the influence of alcohol, the blood sugar content changes, which sharply reduces the likelihood of a correct diagnosis based on the results of the examination. In addition, alcoholic beverages reduce the accuracy of the study due to the effect on medical technology and reagents. The metabolic products of alcohol enter into chemical reactions with laboratory substances, which makes an accurate determination of blood sugar impossible.

Diagnostic systems based on enzymatic techniques are considered the most accurate.

The error can be quite significant.

When will you have to give up alcohol?

If a blood sugar test is scheduled as planned, you need to properly prepare for it. The day before donating blood, you must completely exclude the use of alcohol. Even a few sips of a low-alcohol drink can lead to a decrease in the accuracy of the study.

Drinking alcohol on the day of the test is also not recommended. Until you donate blood for sugar, you cannot drink alcohol. In the event that the analysis is carried out several times a day, you can drink a little only after the last blood sampling.
