Do I need to control my diet with a fasting blood sugar of 5.6?

Do I need to control my diet with a fasting blood sugar of 5.6?

Greetings! First of all, I would like to say that the fact that you are asking such a question shows that you wish to learn about diabetes and are more concerned about your health, and I hope that more of your friends will do the same.

Diagnostic criteria for diabetes mellitus

  • Fasting blood glucose greater than 7.0 mmol/L or 2-hour postprandial blood glucose greater than 11.1 mmol/L

  • Fasting blood glucose greater than 6.1 mmol/L and less than 7.0 mmol/L or 2-hour postprandial blood glucose greater than 7.8 mmol/L and less than 11.1 mmol/L is called abnormal glucose tolerance, which is prediabetes.

According to the diagnostic criteria for diabetes you are definitely not diabetic, not even pre-diabetic, first of all you can breathe a sigh of relief, that is to say, you do not need to control your diet as much as you do for diabetes, but it is still very necessary to check your eating habits.

Medical research has shown that when blood glucose is greater than or equal to 5.6mmol/L, the body's microvessels will begin to be damaged, only to a lesser extent, and with the persistence of this damage, its severity will continue to worsen. Especially as people age, the body undergoes aging and degeneration, this damage to the blood vessels will be more obvious.

So, even though such blood glucose values are not related to diabetes, they give us a hint that we should be concerned about any inappropriate aspects of our lifestyles.

  • Diet: Too much staple food, too much fat, not enough fruits and vegetables, too much salt, etc.

  • Exercise Insufficient daily exercise, lack of 30 minutes of aerobic exercise.

  • Lifestyle Irregular work schedules, smoking and excessive alcohol consumption, sedentary lifestyle, and late nights.

Especially if you have a family history of diabetes, you should always check your lifestyle. In conclusion, although a fasting blood glucose of 5.6 mmol/L is not related to diabetes, it reminds us to pay attention to the details of our lives, and to realize that developing good living habits is the foundation for maintaining good health, and is the most effective way of preventing diabetes, high blood pressure and other diseases.

A fasting blood glucose level of 5.6 should be considered normal, but this normalcy can be categorized into several different situations. Today, Dr. Zhang will give you an explanation.


First of all, let's say that if you are an average healthy person and your fasting blood sugar is 5.6, this should be considered a normal fasting blood sugar level. However, even if this is the case, you need to control your diet, and you can't say that you eat recklessly if your blood sugar is normal. If you consume all kinds of food with impunity, many times it still leads to an increase in blood sugar over time.

Secondly, some people fasting blood glucose elevated, through formal treatment, control blood glucose recovery to 5.6 this normal level, this time this kind of people should still control the diet, can't say what you want to eat on what to eat. Because diabetic patients through the formal treatment, even if the blood sugar is normal, but also can not freely eat and drink, or pay attention to a healthy diet.


In fact, blood glucose health is a very important thing, in the medical profession of diabetes and cardiovascular disease is classified as equal to the risk of disease, that is to say the importance of blood glucose health. Generally speaking, fasting blood sugar should not be more than 6.0mmol/l, if you usually fasting blood sugar from time to time in 6.0mmol/l or more, this time to be particularly alert to the possibility of diabetes. And many people, even if they are not diabetic, are in a pre-diabetic state, and can develop diabetes later in life if they are not careful. Therefore, for many people with abnormal fasting blood glucose, care must be taken to give positive intervention to reduce the chances of further elevation of blood glucose developing into diabetes.

Well, that's all for today, if you want to see more diabetes-related knowledge, you can click the following course to get: Dr. Zhang's blood sugar course

If you are not diabetic, a normal diet is fine.

If you are diabetic, this is something to consider in the following ways:

(1) Every day, the fasting is controlled below 6.1 mmol/L, or just once in a while, the blood glucose is monitored and the blood glucose is fine.

It is recommended that you monitor your fasting blood glucose for a sustained period of time during normal life. If your fasting blood glucose is below 6.1mmol/L, your fasting blood glucose control is still very good. If your fasting blood glucose is over 7.0mmol/L, we need to find out what causes your fasting blood glucose to rise, and find out the cause. (You may be asked to adjust your diet for dinner and additional meals.)

(2) Daily fasting glucose control is pretty good, is postprandial glucose monitored?

Many people, just measure a fasting blood sugar, feel good, and do not monitor. In fact, most people with newly developed type 2 diabetes have poor postprandial glucose control, primarily.

If your postprandial blood glucose is higher than 10mmol/L, you should take diet and exercise control. If your blood sugar does not go down after diet and exercise, you should take medication. (If you are a younger diabetic, I suggest that it is best to control your blood glucose below 7.8mmol/L 2 hours after a meal.)

If you have any questions, you can leave them in the comments section and I'll respond when I see them.

The above answer is provided by Ms. Song Mingyue, a registered dietitian of MicroSugar

Fasting blood glucose 5.6 is normal, don't worry, but make sure you continue to maintain good living and eating habits, just because it's normal now, doesn't mean it will be normal later.



To give you a diagnostic criteria for diabetes.

As you can see from the table above, your fasting blood glucose values are normal, and for the average person, although the limit is at 6.1 mmol/L, it is best to keep it under 5.8 mmol/L preferably for more peace of mind.



When the blood glucose value in the fasting glucose regulation is impaired or impaired glucose tolerance, is the precursor to diabetes, which is usually said to be high blood sugar, but has not entered the diabetes, has been the diabetes reserve. This time you need to tightly control the diet, change the bad lifestyle, included in the very period, if this time again do not pay attention to, still do not care, then eventually into the diabetes.

As the saying goes, "getting sick is like falling down a mountain, getting sick is like pulling out silk", especially the slow diseases are accumulated day by day, prevention is greater than treatment, so we still early prevention, don't wait for the disease to come, and then think of ways to cure. Although modern medical conditions are developed, but some diseases are lifelong carriers.

Fasting blood sugar 5.6mmol / L is normal blood sugar, for this blood sugar level of patients, do not have to worry too much about the diet, there is no excessive restrictions. Although our blood sugar is within the normal range, we still recommend that we do a reasonable and scientific diet, and strive for a balanced impact.

Blood sugar is an important substance for our body's metabolism and energy supply, and is essential for maintaining our normal physiological activities. The normal range of our blood glucose is: ① Fasting blood glucose: 3.9~6.1mmol/L; ② Two hours after meal blood glucose: 4.4~7.8mmol/L.

Diabetes mellitus can be diagnosed when we have symptoms of excessive eating, drinking, urinating and wasting, and if fasting blood glucose ≧7.0mmol/L or two hours after meal ≧11.1mol/L or random blood glucose ≧11.1mmol/L is measured. In the absence of the above typical symptoms of diabetes mellitus, diabetes mellitus can be diagnosed if the above blood glucose is measured twice on non-simultaneous days to reach the standard.

We hope that everyone will correctly recognize that diabetes is not scary, it is preventable and controllable, and the emphasis is on regular diagnosis and treatment. Diabetic patients need to pay attention to reasonable diet, appropriate and regular exercise in daily life, and take medication regularly under the guidance of the doctor, and use insulin replacement therapy if necessary, in order to stabilize blood sugar control, reduce complications and improve the quality of life.

Normal fasting blood glucose is 4.4-6.1 mmol/L, non-fasting blood glucose is 4.4-7.8 mmol/L, and fasting blood glucose 5.6 mmol/L in the normal range, but also to pay attention to regulating the diet, to avoid overeating, overeating, fatty, high-fat diet. Regardless of the condition of blood glucose should be controlled diet!

People nowadays have excessive calorie intake, irrational dietary structure, obesity and serious lack of physical activity, as well as the accelerated pace of life, work pressure, coupled with poor living habits, can often accelerate the formation of atherosclerosis, and potentially latent diabetes will accelerate the process of its transformation into diabetes mellitus.

Dietary treatment is an important basic treatment measure for diabetes, especially pre-diabetes, pre-diabetes is in the critical state of sub-health, if not well control blood sugar let it develop, it is easy to become a real diabetic. Diet control to eat more fruits and vegetables every day can make the risk of stroke lower.

Reasonable diet, balanced nutrition, intake of protein, carbohydrates, fat and other nutrients in the right proportion in order to ensure the normal physiological needs of the body. Such as excess energy can easily lead to obesity, while insufficient energy will lead to wasting and decreased resistance.

1. Should do the staple food quantitative, coarse and fine mix, meat and vegetables with daily cereal intake of 300-500 grams, 200 grams of fruit, fresh vegetables 400-500 grams. Do not pick and choose food.

2. Ensure that dairy and legumes should be consumed daily, requiring 300 ml of milk and milk products and 50 grams of beans and legumes per day.

3. Fish, poultry, eggs, livestock in moderation, livestock and poultry meat 50-100 grams per day, 25-50 grams of eggs, 50 grams of fish and shrimp.

4. Appropriately increase the intake of dietary fiber, but not the more the better, 25-30 grams per day is appropriate.

5. Fats and oils to choose vegetable oil as the main, no more than 50 grams per day; cooking to light, less oil, salt, more use of steaming, cooking, mixing and other cooking methods, and to limit the intake of smoked processed meats.

6. Avoid diets high in salt, sugar and fat.

7. Drink plenty of water, limit alcohol consumption, and limit smoking.

Nowadays, with the improvement of people's living standards, meat, fish and shrimp seafood every day, high-fat high-energy intake is also very common, so the control of diet is an important means of preventing high cholesterol, high blood sugar, in addition to a reasonable diet, but also with the regular exercise and good habits of life and work and rest, fasting blood glucose 5.6 despite the fact that the blood glucose is not high, but also pay attention to the control of the diet from the dietary sources of high cholesterol, high blood sugar The risk of hyperlipidemia and hyperglycemia can be minimized at the source of diet.

Fasting blood glucose 5.6, of course, does not meet the diagnostic criteria of diabetes mellitus fasting blood glucose 7.0 or more, and even the upper limit of 6.1 or more on the report card has not been reached, for this kind of high, but not over the limit of the blood glucose, in the end, should we control the diet? Shouldn't the blood sugar start to be controlled more intensively? We can't give a clear answer just based on a blood glucose value.

Fasting blood glucose 5.6, to tighten glycemic control or not, you should first perform a risk assessment

Fasting blood glucose reaches 5.6, what assessment needs to be done? Of course, it is to do the assessment of whether the blood glucose has the risk of continuing to rise and develop into diabetes. For this kind of chronic metabolic disease of diabetes, if we can do a good job in regulating and controlling the blood glucose as early as possible, and find out the tendency of blood glucose rising and the risk of developing diabetes before developing diabetes, and do a good job in the intervention of the disease, we can not only reduce the risk of diabetes, even if we eventually develop diabetes, but also greatly slow down the time of onset and development of diabetes, and reduce the risk of complications of diabetes. Even if diabetes eventually develops, it will also greatly slow down the onset of diabetes and the development of the disease process, reduce the risk of complications of diabetes, therefore, from the perspective of preventing diabetes, if you find that the fasting blood glucose to 5.6, already thought to pay attention to the issue of blood glucose control, first of all, we should praise you for this "prevention is better than cure" attitude.

How should risk assessment be done? We may want to assess how high or low our risk of diabetes is in the following areas while assessing our understanding of our blood glucose levels -

  • Do you have a blood glucose level from your regular checkups, what was your original blood glucose level, has it always been around that level, or has it gradually risen over the past two years? If there is a gradual increase, you should pay more attention to it.
  • Is there a family history of diabetes? Especially if there are any diabetics in the immediate family. Although diabetes itself is not hereditary, insulin-resistant body mass, etc., can be somewhat familial, if one has a family history of diabetes himself.
  • Whether you have a high-fat, high-sugar diet, smoking, long-term heavy drinking, often stay up late and other aspects of bad habits, these bad habits are also important risk factors for elevated blood glucose, if you have a variety of bad habits, not only to pay more attention to blood glucose levels, blood pressure and blood fat levels must also pay more attention.
  • There is no hypertension, hyperlipidemia and other related chronic diseases, these chronic problems, which increase the risk of cardiovascular disease at the same time, is also an important complication with diabetes.
  • There are no obesity, fatty liver problems, obesity, fatty liver problems, etc., are at high risk for developing insulin resistance and elevated blood glucose, and also deserve special attention.

If the above aspects of the problem are not, physical examination of blood glucose level is relatively high, may wish to reflect on their own have not strictly maintain fasting, or recently there is no overeating, excess energy, maintain a normal diet for a period of time, you can go back to review the blood glucose level, perhaps the blood glucose level will be further reduced, and there is no need to be overly concerned.

If one or more of the above risk assessment factors are summarized, and your fasting blood glucose reaches 5.6, it is advisable to pay more attention to the risk of elevated blood glucose and diabetes prevention.

Fasting blood glucose 5.6, how to regulate the intervention has to be considered

At this blood glucose level, of course, there is no need to take hypoglycemic drugs, and the first thing to consider is to prevent further elevation of blood glucose by strengthening lifestyle interventions.

Dietary management is of course a very important aspect, through a reasonable arrangement of dietary structure, control dietary intake, minimize the risk of excessive calorie intake, eat more fresh vegetables, eat more grains and cereals, soy products, dairy, high-fat and high-sugar less to eat, meat in moderation to eat, refined rice and flour to eat less, so that not only balanced supplementation of the body's nutrients, but also will not cause to eat "too much too much", is a very important principle of dietary management of diabetes, for friends with obesity problems should pay more attention to eat less to strengthen weight control by adjusting intake to improve blood glucose levels. ", increase the burden of blood sugar metabolism, is very important diabetes dietary principles, for friends with obesity problems, pay more attention to eat less, by adjusting the intake to strengthen weight control, improve blood sugar levels.

Exercise is also an important aspect of strengthening blood sugar control, choose moderate intensity aerobic exercise, long-term adherence, to enhance the body's metabolic capacity, strengthen the utilization of blood glucose metabolism, assist in regulating the lowering of blood glucose, is a very important way of life regulation. The intensity of exercise, but also to combine the specific situation of the body, obesity problems, usually not much physical activity, may wish to focus on time, more exercise, exercise intensity can also be higher, usually itself on physical labor, can be combined with the actual situation, in a number of sports training, to improve blood sugar levels.

In addition, some of the bad habits of life, smoking and drinking, staying up late, etc. should also pay more attention to actively improve, maintain a healthy and good habits, in order to regulate our blood sugar levels, in order to have good health.

Do a good job in the above life conditioning at the same time, but also pay more attention to the monitoring of blood glucose, for fasting blood glucose to 5.6 friends, if you can adhere to the above habits, you may also want to go every six months to review the blood glucose level, if the blood glucose level has been effectively controlled, then continue to maintain healthy lifestyle habits, if the blood glucose is still high, or gradually rising, it is necessary to alert the risk of diabetes once the blood glucose further rises to the level of diagnosed diabetes level through life conditioning can not be effectively controlled, or should consider using glucose-lowering drugs to regulate the control. Once the blood glucose level rises further to the level of diagnosed diabetes, and cannot be effectively controlled through lifestyle modification, you should consider using hypoglycemic drugs to regulate and control the blood glucose level.

We all know that the normal range of fasting blood glucose is 3.9-6.1 mmol/l, so a fasting blood glucose of 5.6 really doesn't meet the diagnostic criteria for diabetes. But there is a pre-diabetic state between normal people and diabetics, which we also call impaired fasting glucose. This stage is a reversible stage, poor control will turn into diabetes, good control may return to normal.



Do I need to control my diet with a fasting blood sugar of 5.6?

With the above analysis, we know that fasting blood glucose 5.6 actually needs to be taken seriously, but of course it does not need to be too nervous. The usual diet needs to pay attention to low fat, low salt and low sugar, eat more vegetables and fruits. If the body type is obese, it is recommended to exercise to reduce weight, in addition to the prevention of high blood sugar, the prevention of high blood pressure and high blood fat is also very helpful. For people in the impaired fasting glucose state, through appropriate life and dietary interventions, most people can return to normal without turning into diabetics.

Dr. Duan's Q&A Online 🚀 Relationship Between Blood Sugar and Diet 🚀

Fasting blood glucose 5.6 is in the normal blood glucose range, but normal blood glucose does not mean that the diet can be reckless. My advice is that people with diabetes or other chronic diseases, such as hypertension, hyperlipidemia, and cardiovascular diseases, must have a strict dietary control; even healthy people should have a reasonable diet.



Normal range of blood glucose:

Fasting blood glucose <6.1 mmol/L, and 2-hour postprandial blood glucose <7.8 mmol/L.

The diagnostic ranges for diabetes mellitus are: fasting blood glucose ≥ 7.0 mmol/L, and 2-hour postprandial blood glucose ≥ 11.1 mmol/L. Those who fall between the range of normoglycemia and diabetes mellitus are classified as prediabetic. Both diabetic and pre-diabetic patients require strict dietary control.



Fasting blood glucose of 5.6 is within the normal blood glucose range, and dietary requirements vary for different groups of people.

(1) Those who have diabetes mellitus, indicating good blood sugar control. Those who do not have diabetes but have other diseases that require dietary control, such as hypertension, hyperlipidemia, coronary heart disease, stroke, fatty liver, etc., need strict dietary control.

(2) For people who are healthy and do not have chronic diseases, especially those who are older, they should eat sensibly to prevent diseases.

Nowadays, there is a tendency for many diseases to become younger, and the number of people who are overweight and obese is gradually increasing. Therefore, it is even more emphasized that one should have a reasonable diet and should not eat whatever one wants and as much as one wants.

Dr. Duan specifically warned:


(1) Reasonable dietary measures include: low salt and low fat; cessation of smoking and restriction of alcohol; moderate amount of carbohydrates and proteins; and sufficient fresh vegetables.

(2) It is often said that "illness enters through the mouth", which emphasizes the important role of a proper diet.

Hello! I am an endocrinologist and would be happy to answer your questions!

Fasting 5.6 is still in the normal range, but it's close to the upper limit of normal, 6.1. Complete blood glucose includes fasting, postprandial glucose and glycated hemoglobin, so only fasting glucose is not a good judge, and most people's postprandial glucose is more likely to rise, so even if the fasting is normal, postprandial glucose is elevated to a certain extent may reach the diagnostic criteria for diabetes.

For those with a family history of diabetes, overweight or obesity, cardiovascular disease hypertension and hyperlipidemia, it is very important to measure postprandial blood glucose and glycated hemoglobin.

In fact, a healthy diet is recommended regardless of high blood sugar, including low salt, low sugar and low fat.
