Why does blood sugar drop after a meal? Why is blood sugar always high after a meal?

The individual's postprandial blood sugar will drop, depending on the time of personal testing, it may be that after the meal, the food has not been completely digested, the glucose in the individual's blood has not been replenished in time, and the glucose will be consumed after personal activities, and the individual needs to be re-tested every once in a while.

Because the body's pancreatic islets secrete a large amount of insulin after a meal, insulin can promote blood sugar and glycogen, thereby reducing blood sugar concentration.

Although the blood sugar of normal people rises after eating, it fluctuates within a certain range. Patients with type 2 diabetes may have excessive insulin secretion (hyperinsulinemia) and delayed peaks, and insulin concentrations are maintained at high levels without returning to baseline, resulting in low or even hypoglycemia after meals.

Food contains sugars, starches, and fiber, all of which are metabolized into glucose in the body. If you consume too much sugar, starch and fiber, it can cause your blood sugar to rise. In addition, drinking alcohol and eating very oily foods can also cause blood sugar to rise.

In addition, a postprandial increase in blood sugar may also be due to decreased insulin secretion or insulin resistance, which are typical symptoms of diabetes. Finally, postprandial blood sugar increases can also be due to other diseases or medications, such as liver disease, kidney disease, endocrine disorders, etc.

Therefore, if you notice an increase in blood sugar after a meal, you should monitor your blood sugar and do it under the guidance of your doctor**.

Blood sugar is a concern that people have always been concerned about, and for the prevention of diabetes, you should go to the hospital regularly to check your blood sugar. There are two ways to check blood sugar, one is postprandial blood sugar and the other is fasting blood sugar. Some people have high postprandial blood sugar and normal fasting blood sugar, is this diabetes?

Let's take a look.

When many people check their blood sugar, they will check their postprandial blood sugar and fasting blood sugar, but some will have high postprandial blood sugar and normal fasting blood sugar. Many people think that they must have diabetes, but in fact, high postprandial blood sugar and normal fasting blood sugar are more likely to be diabetes, but it does not mean that they must have diabetes. There are many conditions that cause high postprandial blood sugar and normal fasting blood sugar, depending on the specific test results, and if the value of further examination is consistent with the value of diabetes, then diabetes can be diagnosed.

1. Proper control of diet

It is also not advisable to overeat, and it is best to eat three meals at regular intervals, because overeating can cause large fluctuations in blood sugar after meals.

2. Exercise is essential

If the postprandial blood sugar is relatively high, then aerobic exercise must be carried out, and it is best to exercise after an hour after the meal, because exercising at this time can have a better control of blood sugar. In addition, it is best not to exercise too vigorously, and you should choose low-intensity aerobic exercise. For example, walking or jogging or doing some aerobics are all good options.

3. Obese people should **

Many people have high blood sugar after meals, so it is easy to indulge themselves in the fear of getting diabetes. In fact, high postprandial blood sugar does not necessarily mean that you have diabetes, through strict dietary control and good living habits, you can completely control postprandial blood sugar at a normal level, so do not have too much psychological pressure, to maintain a good psychological state, if you have been in a nervous, depressed or troubled state of mind, blood sugar control will not be done well.

High postprandial blood sugar and normal fasting blood glucose do not necessarily mean that you have diabetes, and the diagnosis should be confirmed based on more detailed test results. If the blood sugar is only high after a meal, you can still control your blood sugar within a reasonable range through certain methods.

Summary. Hello, low blood sugar after a meal, is due to.

1. Daily life: eating foods with high sugar content and emotional agitation have an inducing effect on the onset of postprandial hypoglycemia.

2. Drugs: induced hypoglycemia caused by hypoglycemic drugs. The risk of hypoglycemia is greatly increased when glucose-lowering drugs are combined.

What are the causes of low postprandial blood sugar and high postprandial blood sugar?

Hello, low postprandial blood sugar is due to 1. Daily life: eating foods with high sugar content, emotional agitation, etc., have an inducing effect on the onset of postprandial hypoglycemic curvature. 2. Drugs:

Inducible hypoglycemia caused by hypoglycemic drugs. The risk of hypoglycemia is greatly increased when hypoglycemic drugs are used in combination.

Low fasting blood sugar and high postprandial blood sugar are mostly caused by excessive intake, or unreasonable dietary structure, drinking porridge, eating noodles and other easily absorbed staple foods. In addition, if you do not exercise properly after a meal, it can also cause blood sugar to rise. So if you want to lower your blood sugar after a meal, the first thing you need to do is to control your diet and strengthen exercise.

In terms of diet, we should try to avoid eating high-fat, high-calorie, high-sugar food, do not eat thickened, sugary, fried, fried food, the staple food is mainly steamed bread and rice, you can eat coarse grains appropriately, and the amount of staple food per meal is controlled at about two taels.

Causes of high blood sugar after a meal

If people measure a blood sugar value above 11 two hours after eating, then this condition can be defined as high blood sugar after a meal. Some people with diabetes may experience this condition. Of course, a small number of patients have this condition due to other reasons, and in the following we will give you a detailed description of what are the causes of high blood sugar after meals.

Causes of high blood sugar after a meal

First of all, if people themselves have type 2 diabetes, then it is easy for blood sugar to rise after eating.

Secondly, for some very obese people, high blood sugar after meals is also a common occurrence. If people eat foods that are too high in sugar when eating, then it can also trigger high blood sugar after a meal. For some older people, if they do not control their diet, they are prone to high blood sugar after eating.

If the high blood sugar is very serious, but not enough attention is paid to it, then it is likely that the spring grandson will cause people to get diabetes, and in severe cases, it will even damage the kidneys.

For people with high postprandial blood sugar, in addition to being positive**, they must be moderate in their diet.

What are the causes of high postprandial blood sugar, it can be seen from the article that uncontrolled diet or excessive obesity can cause people to have high postprandial blood sugar. If people have high blood sugar after a meal is very severe, then Asho must be carried out**.

If your blood sugar rises after breakfast, it may be related to the hormone glycemic hormone in your body. Physiological hormone secretion can lead to an increase in blood sugar. Another reason is that the breakfast mix may not be reasonable, as our breakfasts are usually busy.

At this time, we may rush to eat some foods that will increase the glycemic index, such as steamed buns, porridge, bread, without vegetables, proteins, etc., which will increase blood sugar after meals.

The use of hypoglycemic drugs is not appropriate. Many people only use long-term secretagogues or insulin, which can only control fasting blood sugar, and postprandial blood sugar control is relatively poor, so postprandial blood sugar will increase at this time; It's an uncontrolled diet. Especially for the Chinese, we eat better for dinner and lunch.

At this point, it is easy to cause a sharp rise in blood sugar after a meal. Exercising too little can also cause blood sugar to rise after a meal.

Most people have lunch for dinner and eat a very rich diet. The Chinese diet is dominated by carbohydrates, with carbohydrates accounting for 50%-60%. Carbohydrates are absorbed very quickly relative to plant proteins, which can easily lead to an increase in blood sugar after lunch; If they are all carbohydrates, such as one or two white noodles made into one or two noodles or one or two steamed buns, the degree of absorption is different.

Manju is absorbed faster and gelatinized faster than steamed food, and pancakes are absorbed more slowly than the other two foods. Different cooking methods result in different degrees of absorption of carbohydrates, resulting in an increase in blood sugar.

Some diabetics like to eat things after meals, such as fruits. While diabetics can eat some fruits in moderation when their blood sugar control is relatively stable, they can't eat them after meals. If they eat fruit after a meal, they will increase their blood sugar after a meal.

If you can't control your blood sugar well, eating fruit is undoubtedly suicidal. Fruits and other snacks should be eaten between meals, not after meals, which should be more noticed. If you notice that your postprandial blood sugar is relatively high, don't take it lightly at this time, but find out why.

If the blood sugar is too high after a meal, it is relatively harmful.

Because it is a metabolic disease, diabetic patients after eating, his insulin secretion is insufficient, so it will cause blood sugar to rise, usually relax and exercise appropriately.

This is because there are many sugars and fats in food, which are absorbed by the body, so it is easy to cause blood sugar to rise.

Because some foods have a certain amount of sugar in them, after these sugars enter the body, they will affect the body's blood sugar, so that blood sugar will rise.

A one-hour postprandial blood sugar of millimoles per liter is within the normal range, because this is a scientific standard, and it is abnormal if it is above or below this range.

** It is within the normal range, because blood sugar has a normal control range, and the sugar content of food is not very large, so there will be no blood sugar problems.

Blood glucose** levels are within the normal range. Some sugar is consumed during meals, and the amount of sugar consumed determines the normal range of blood sugar.
