Hello! Consider two possibilities given the questions you have asked:

1、How tall is normal for a diabetic?

2、How high is normal blood sugar for diabetics?

Question one:

Nutritionist thought it was pointless to talk about how tall normal height is in isolation. The only way to talk about normal is to have a certain proportion of height and weight. So what ratio should it be in to be considered normal?

The World Health Organization has given us a good yardstick to judge this, and that is BMI (Body Mass Index). Body Mass Index (BMI) = Weight (kg) ÷ Height^2 (m).

Men: BMI <20，提示偏轻；20~25，提示适中；26~30；提示过重，30~35，提示肥胖；BMI>35, suggesting very obese.

Women: BMI <19，提示偏轻；19~24，提示适中；25~29；提示过重，29~34，提示肥胖；BMI>34, suggesting very obese.

Some experts state that the ideal body mass index is 22.

In adulthood, the height can not be in the growth, then want to height and weight to reach a normal ratio, you can only work on the weight. Type 2 diabetes patients, in the early stage of the onset of the disease, weight is often on the heavy side. This tends to increase the burden of insulin, which is why weight control and appropriate weight loss are recommended.

Question two:

In type 2 diabetes mellitus, the average adult has ideal glycemic control: fasting, 4.4-6.1 mmol/L; non-fasting, 4.4-8.0 mmol/L. Good control: fasting, less than or equal to 7.0 mmol/L; non-fasting, less than or equal to 10 mmol/L.

Type 2 diabetes mellitus, state of glycemic control in older adults: fasting, 5.0 to 7.2 mmol/L; bedtime glucose, 5.0 to 8.3 mmol/L (data from the 2017 guidelines for the prevention and treatment of type 2 diabetes mellitus)

Attached is a chart of metabolic control indicators for type 2 diabetes that I hope will help you:

I hope that the answer of the Nutritionist will be helpful to you, and I hope that you will point out any shortcomings!

For diabetics, the aim of treating diabetes is to keep blood glucose values at the desired level through a combination of diet, medication and exercise, and to reduce the various complications caused by long-term high blood glucose.

You can't say what level of blood sugar is considered normal for a diabetic, you should say what level of blood sugar is ideal.

Since the specific condition of each diabetic patient is different, the corresponding ideal blood glucose level cannot be generalized.

with regards toNewly diagnosed young patients with long life expectancy, no serious cardiovascular complications, and low risk of hypoglycemia. Ideal glycemic control goals are: fasting blood glucose control at 4.4 to 6.0 mmol/L; two-hour postprandial blood glucose or any blood glucose at: 6 to 8 mmol/L; and glycosylated hemoglobin: <6.5%, or more stringent <6.0%.

对Patients with recurrent hypoglycemic episodes, elderly patients >80 years of age, patients with severe cardiovascular and cerebrovascular diseases and patients with risk factors for severe cardiovascular and cerebrovascular diseases, patients with a life expectancy of <5 years, elderly people unaccompanied by their family members, and mentally challenged patients.The requirement that glycemic control should be relaxed to avoid strict glycemic control and hypoglycemia, which induces adverse events; the ideal glycemic targets for these patients are: fasting glucose control at 8-10 mmol/L; two-hour postprandial glucose or any glucose at: 8-12 mmol/L, or even relaxed to 13.9 mmol/l; glycated hemoglobin: <8%.

For the rest of the general population, the ideal glycemic targets are: fasting blood glucose control at 4.4-7.0 mmol/L; two-hour postprandial blood glucose or any blood glucose at: <10 mmol/L; and glycosylated hemoglobin: <7%.

In summary: diabetic patients, the ideal glycemic control goals should be integrated with the patient's specific situation, set up in line with their own goals, in order to ensure safety, without hypoglycemia under the premise of the blood glucose control can be made as low as possible.

Dr. Duan Q&A Online 🔑Diabetic patients control their blood sugar levels 🔑

The first task in the treatment of diabetes - control of blood glucose in order to prevent various complications. However, all people with diabetes cannot be measured by the same standard for blood glucose control goals: control goals are different for 40 and 70 years old, and different for those with and without heart disease. So what range of blood glucose control is normal for different diabetic populations?

Indicators to look at blood glucose control include fasting blood glucose, 2-hour postprandial blood glucose, and glycosylated hemoglobin.

(1) Fasting blood glucose and 2-hour postprandial blood glucose: can see how well the blood glucose is controlled, and frequent measurements can keep you informed of the effect of diet and exercise on blood glucose.

(3) Glycated hemoglobin: Reflects the average blood glucose level over a 3-month period, independent of diet, exercise, mood, etc., and is one of the main indicators of long-term blood glucose control. The relationship between glycated hemoglobin and the average blood glucose level (not fasting blood glucose, but the average blood glucose throughout the day) is approximately: 6% ≈ 7.0, 7% ≈ 8.6, 8% ≈ 10.2, 9% ≈ 11.8.

Glycemic control in different diabetic patients:

(1) For all diabetic patients, a fasting blood glucose of 4.4 to 7.0 mmol/L and a two-hour postprandial blood glucose of <10.0 mmol/L are recommended.

(2) In most patients with diabetes, the goal of glycated hemoglobin control is <7%.

(3) Diabetic patients with shorter duration of diabetes, younger age, longer life expectancy, no complications of the heart, brain, kidney, eye, etc., no co-morbid cardiovascular disease, and no hypoglycemia. Glycated hemoglobin can be controlled more strictly, <6.5%.

(4) Diabetic patients with a history of severe hypoglycemia, older age with shorter life expectancy, significant microvascular or macrovascular complications, severe comorbidities, and long duration of diabetes. The control goal for glycosylated hemoglobin can be tolerated with a point of <8.0%.

(5) In children and adolescents, fasting blood glucose <7.0 mmol/L and glycosylated hemoglobin below 6.5% when possible.

(6) Pregnant women with fasting blood glucose < 5.3 mmol/L, 1-hour postprandial blood glucose < 7.8 mmol/L; 2-hour postprandial blood glucose < 6.7 mmol/L. Also avoid blood glucose < 4.0.

(7) The recommended glycemic control goal for most critically ill and diabetic patients undergoing proposed surgery is 7.8 to 10.0 mmol/L.

Dr. Duan specifically warned:

(1) Methods of controlling blood glucose: Lifestyle modification as a basic measure, along with oral medication and insulin for lowering blood glucose.

(2) In diabetic patients, it is also important to control lipids (total cholesterol <4.5, triglycerides <1.8，高密度脂蛋白>1, cardiovascular disease LDL <1.8, no cardiovascular disease LDL <2.6), blood pressure (<130/80), and body mass index (<24) at the same time. Because, these are risk factors for cardiovascular disease.

(3) Measure your blood glucose diligently. For the convenience of measurement, it is best to bring your own blood glucose meter and compare it with the results of blood draws on a regular basis.

Do you have confirmed diabetes, or just a high blood sugar test? I don't know your situation, so I'll tell you all about it and be patient with you!

First of all, let's say you checked your blood sugar and the results showed a high value, that doesn't mean you are diabetic! First of all, the criteria for diabetes, because the data is on the high side, it may be confusing to read, so I write more simple, you can always ask me if you have questions!

Fasting blood glucose ≥ 7.0 mmol/L or 2-hour postprandial blood glucose ≥ 11.1 mmol/L in individuals with typical symptoms.The first thing to note here are three things: first, what are the typical symptoms, the common one is "three more and one less", that is, eating more, drinking more, urinating more, weight loss; second, how to calculate the postprandial blood glucose from when it is calculated, from the entrance of the first mouthful of your meal; third, because of the difference between the chemicals, so the value written here may be biased. Third, because of the difference between the chemical reagents, so the value written here or deviation, so if you are using your own blood glucose meter self-test, you should first read the instructions on the circle of this value, if you are to go to the hospital for examination, it is more convenient, the laboratory will indicate the normal range of blood glucose shown in the examination, at a glance!

If you just have a high blood glucose number without typical symptoms, then don't jump to conclusions too soon, because there are two other reasons for high blood glucose, firstly, excessive consumption of sweets the day before, because it exceeds the metabolizing capacity of the body, so the blood will retain more sugar to the point that the results of the next day will be abnormal, and secondly, glucose tolerance abnormality, which is said to be the result of a fasting glucose that is less than 7.0 and greater than or equal to 6.1mmol/L, or glucose greater than or equal to 7.8 and less than or equal to 11.1mmol/L after the glucose tolerance test, this state, also known as pre-diabetes, is a reversible state of glucose abnormality, and it is also your only chance to get rid of diabetes!

In addition, if you have been diagnosed with diabetes, then I have to ask about your age and physical condition. If you are an elderly person, then you can relax the standard appropriately, and control your blood glucose as follows: fasting blood glucose 6-8mmol/L, or 2-hour postprandial blood glucose 8-9mmol/L; if you are not only an elderly person, but also suffer from cardio-cerebral vascular diseases, then you have to change another standard for your blood glucose control. To change another standard, as follows: fasting blood glucose 7 ~ 9mmol / L, or 2 hours after the meal blood glucose 8 ~ 11.1mmol / L; so refined blood glucose standards, because of different age stages, different physical conditions of people with different blood glucose content needs, one is to prevent blood glucose is too high to cause complications, and the second is to prevent blood glucose is too low on the cardiovascular and cerebral vascular effects, toEnsure quality of life.

The above is purely a personal opinion, don't spray if you don't like it! If you have a different viewpoint, please let us know!

Thanks for the answer. According to the guidelines for the diagnosis and treatment of diabetes mellitus, diabetes mellitus is diagnosed when the fasting blood glucose is greater than or equal to 7 mmol/l and the blood glucose after 2 hours of OGTT is greater than or equal to 11.1 mmol/l. Prolonged hyperglycemia brings patients lifelong pain and incurable complications, so diabetics want their blood sugar to return to the normal range.

Is it best for all diabetics to return their blood sugar to normal or not? In fact, this is not, this needs to be based on the patient's specific situation. Usually divided into the following cases, for normal young adults and older people in good physical condition, this type of diabetic patient's blood glucose needs to be strictly fasting control at 6.1-7mmol/l, two hours after the meal control at about 7-8mmol/l, glycated hemoglobin control between 6.5-7%. Because diabetes is expected to be longer in this group of patients, tight glycemic control has favorable benefits for future quality of life and progression of complications. The recommended glycemic control target for most diabetic patients hospitalized for surgery is 7.8-10.0 mmol/L. For a few patients, such as those at low risk of hypoglycemia, those who are to undergo cardiac surgery, and those who are undergoing other delicate surgeries, a more stringent glycemic control target of 6.1-7.8 mmol/L may be recommended. Pregnant women are required to have a glycemic haemoglobin of <7.0%, as insulin secretion is more intense in pregnant women, and therefore Pre-meal blood glucose control at 3.9-6.5mmol/L and post-meal blood glucose below 8.5mmol/L. For the older elderly, patients with a history of severe hypoglycemia, shorter life expectancy, and significant microvascular or macrovascular complications, the glycemic control target is more relaxed, with an HbA1c target of about 8.0%.

Does high blood sugar mean diabetes? When is diabetes diagnosed?

We know that blood glucose values are constantly changing and that factors such as diet and exercise can affect them. Therefore, it is important to know at what time of the day to take blood glucose measurements.

Random blood glucose testing

Literally, the word 'random' means that this test is not affected by time of day and can be done at any time of the day. Compared to the other two tests, this is the most convenient way to measure blood glucose.

With this test, diabetes is diagnosed if the person's blood glucose level is greater than 11.1 mmol/L. If the blood glucose level is still high, the person is diagnosed with diabetes. The diagnosis of diabetes mellitus is made if the blood glucose level remains high after two more random blood glucose measurements on the same day.

Fasting Blood Glucose Test

This test is usually done 10 hours after eating dinner, when blood glucose is least affected by food.

A diagnosis of diabetes mellitus can be made if the subject's fasting blood glucose value is greater than 7 mmol/L. In conjunction with a random blood glucose test, if the random blood glucose value is greater than 11.1 mmol/L, diabetes is diagnosed.

Glucose tolerance test (OGTT)

This test requires the patient to drink 75 grams of powdered glucose after a fasting blood glucose measurement, and then the change in blood glucose level is measured. Generally, we check the blood glucose value at 1 hour and 2 hours after taking the glucose powder. Based on the fasting and 2-hour blood glucose values, it is possible to determine whether or not the patient has diabetes.

(1) Blood glucose values that are higher than the normal range but cannot be categorized as diabetes mellitus. Clinically, this group of patients is diagnosed as "impaired glucose tolerance".

(2) In the OGTT test, the blood glucose value at 1 hour after a meal cannot be used as a diagnostic criterion for diabetes mellitus, but if the blood glucose value at this time is greater than 10 mmol/L, it should not be taken lightly even if it is judged to be normoglycemic according to the two criteria of fasting and 2-hour glucose values.

This rapid rise and fall in blood glucose after a meal can be seen in patients with hyperthyroidism and after a major gastrectomy. These people have the "potential" to develop diabetes and need to pay extra attention to their blood glucose levels.

(3) The OGTT test is a more accurate diagnostic method, and it can also provide information that is not known from random and fasting blood glucose tests.

(4) When the OGTT test is performed, it is also helpful to measure insulin levels at the same time, fasting, 1 hour after a meal, and 2 hours after a meal, to understand the relationship between eating and insulin secretion in the subject.

"Impaired glucose tolerance" is a warning sign of diabetes.

When first hearing that you have 'impaired glucose tolerance', individual people react differently.

Someone took a long breath of relief: luckily, I'm not diabetic yet!

Others frown and lament: am I going to get diabetes soon?

Indeed, this critical diagnosis is always confusing. And the fact that type 2 diabetes always goes through such a critical state in its development means that 'impaired glucose tolerance' is a warning sign of diabetes.

Of course, some patients will continue to be in this 'critical' state for a long time, and even return to normal blood glucose. But all in all, due to genetic factors and lifestyle habits, the majority of patients will eventually transition from a critical state to diabetes.

Many 'critical' patients also suffer from hyperlipidemia and hypertension, and if these factors persist for a long period of time, atherosclerosis is likely to occur, which can ultimately lead to the development of ischemic heart disease.

Therefore, 'critical' patients should not ignore their 'impaired glucose tolerance' and should adopt good lifestyle habits and healthy diet with moderate exercise.

Urine Glucose Screening

In addition to the blood glucose tests mentioned above, there is also the urine glucose test, which provides an initial screening to speculate on the level of blood glucose values.

With normal kidney function, we can detect glucose in urine when the blood glucose value exceeds 160 ~ 180 mg/dl. Since the normal blood glucose value does not exceed 140 mg/dl, it is very difficult to find sugar in the urine of healthy people.

Based on the positive urine glucose result, we can deduce that the subject's blood glucose value is out of the normal range.

However, because of individual differences in the kidneys, some subjects may have a positive urine glucose test even when their blood glucose level is normal, which we call "renal glycosuria". In addition, there are also cases where the presence of urinary glucose is caused by factors such as eating patterns, exertion, advanced age, and so on. In all these cases, we cannot conclude that the patient is diabetic.

Therefore, when urine sugar is positive, it is best to choose another appropriate blood glucose test to confirm the diagnosis.

Pre-meal blood sugar is 7, but after I normalize, it's still 5-6+. Got a question about science?

A 2-hour postprandial blood glucose of no more than 10 points and a fasting blood glucose between 3.9 a 6.1 are considered normal.
