Is it normal that the blood sugar level is 53 in the morning and 2 hours in the afternoon when fasting?

Most people need to check their blood sugar on an empty stomach. So if the blood sugar levels are both 5.3 mmol in the morning and 2 hours in the afternoon, is this normal? If you did not eat at noon, this value is within the normal range, because this test meets the fasting condition, which means not eating for more than ten hours. Usually, fasting examinations are performed more frequently in the morning. Let us learn some knowledge about fasting below.

1. In general, the specific requirements for fasting required by laboratories are: the night before blood collection, the person who wants to be examined should maintain his usual living habits, maintain a normal diet structure, eat light meals, avoid drinking alcohol, coffee, or strong tea, and get a good rest. When you get up the next morning, don't eat breakfast, drink little or no water, don't do morning exercise, and go to the hospital with a calm mind and wait for blood drawing. This kind of blood sample is a good sample that accurately reflects the condition.

2. As we all know, taking medicine can be divided into "empty stomach" and "full stomach". Many medicine instructions state "take before meals" or "take after meals". What is considered "before meals" and what is considered "after meals"?

"Take before meals" means that this medicine needs to be taken on an empty stomach, 1 hour before meals or 2 hours after meals to facilitate absorption. If you have just eaten a lot of snacks before a meal, then "before meal" at this time is not "empty stomach" and cannot be considered as a real "before meal".

"Take the medicine after a meal" means taking the medicine half an hour after a full meal, using food to reduce the drug's irritation to the gastrointestinal tract or promote the gastrointestinal absorption of the drug. Similarly, if you have just eaten a lot of snacks before a meal, you don’t have to be dogmatic and wait until after the meal to take the medicine, because you will already be “full” at this time.

3. When we say you cannot eat tomatoes, bananas, etc. on an empty stomach, it means before each meal, that is, four or five hours after a meal. Of course, if you eat a lot of snacks before a meal, it is not considered fasting.
