Why do diabetics have the dawn phenomenon ?

Diabetic patients have low blood sugar at night, and their blood sugar will rise in the morning, because the blood sugar hormone in the body will surge at dawn, which will promote the body's liver glycogen synthesis and release into the blood, resulting in high blood sugar.

Diabetic patients have blood sugar in their bodies that rise at dawn due to the body's own actions. There is a medical justification for this, and it is recommended to eat less at night when you go to bed. Reduce sugar intake.

The "dawn phenomenon" refers to a marked increase in blood sugar in the early morning, which is caused by excessive secretion of adrenal corticosteroids in the early morning.

It is mainly caused by the defective function of insulin B cells and insufficient insulin secretion in diabetic patients. This condition is often seen in people with insulin-dependent diabetes.

The dawn phenomenon of diabetes mellitus refers to the good control of blood sugar at night and the occurrence of hypoglycemia, but at dawn, there is an increase in blood sugar for a short time, which may be due to the increased secretion of some insulin-antagonistic hormones such as cortisol, growth hormone, and glucagon in the early morning, or the insufficient insulin effect, which is insufficient to inhibit the decomposition and output of liver glycogen induced by glucagon during fasting. It is common in patients who have poor nighttime sleep, are obese, have fatty liver disease, or have sleep apnea syndrome. In layman's terms, it is the phenomenon of diabetes dawn, which is that diabetic patients wake up in the morning when their blood sugar is particularly high.

Growth hormone, glucocorticoids, etc., during this time of dawn, the secretion of these glycemic hormones is gradually increasing, so blood sugar will gradually increase. For healthy people, when blood sugar is mildly elevated, it can secrete enough insulin to suppress them, and then control blood sugar so that it does not rise. However, for patients with diabetes, their insulin secretion will be impaired or have insulin resistance, so they will not be able to secrete enough insulin, or produce enough physiological effects to antagonize this phenomenon of dawn hyperglycemia.

If you want to choose insulin, choose long-acting, if you want to choose oral medicine, you should choose some action time can be 24 hours, such as once a day, the time is very long, if the action time is less than 24 hours, then it may be at night to let the patient take some medicine, let this drug lower the blood sugar the next morning, through this method to solve the patient's dawn phenomenon. It is generally believed that the dawn phenomenon is caused by the excessive secretion of glucocorticoids, growth hormones, etc., which raise blood sugar in the early morning. The best way to combat the dawn phenomenon is to use an insulin pump and increase the morning insulin dose appropriately.

If you are injecting insulin subcutaneously, you can inject medium-acting insulin before bedtime (around 10 o'clock at night), so that the peak effect of insulin will be about 4 o'clock in the morning, which also has a certain effect. Taking metformin before bedtime can lower nighttime blood sugar, but it is important to prevent nocturnal hypoglycemia. The oral drug diphenylcycladine has a certain effect of inhibiting hormone secretion, and taking it before bed has the effect of inhibiting the secretion of glucocorticoids and growth hormone.

In addition, bromocriptine also has the effect of lowering fasting blood sugar, and it can also be tried. Therefore, the first thing to do is to correct these triggers, such as weight control, improve fatty liver, improve sleep at night, and take some corresponding medications when necessary.

The dawn of diabetes phenomenon is when diabetic patients wake up in the morning with very high blood sugar. Some hormones in the body begin to be released, including catecholamines and growth hormone, which are antagonistic to insulin, and insulin lowers blood sugar.

At this time, you should go to the hospital for examination, be sure to eat a light diet, do not eat high-sugar and high-salt food, do not eat supper, do not smoke, do not drink, must strengthen exercise, and eat more vegetables and fruits.

When diabetes mellitus occurs at dawn, blood sugar should be tested in time, medication should be carried out, and trisomatostatin** should be used.

It can be treated with acupuncture, Chinese medicine, Western medicine, acupuncture and blood sugar lowering drugs.

It can be done by taking medication**, so that the problem of diabetes can be improved, and the diabetes can be reduced quickly.

You can take some hypoglycemic drugs in advance before going to bed, so that you can control your blood sugar in advance, and the effect is better.

The dawn phenomenon of diabetes mellitus refers to the patient's blood sugar is stable at night and has a significant increase in blood sugar in the early morning. The patient is confused and does not know what is causing the increase in blood sugar. The dawn phenomenon may be related to glycemic hormones.

When people wake up in the morning, they secrete more glycemic hormones, causing blood sugar to rise. In order to prevent the dawn of diabetes, patients can use long-acting insulin and drugs that inhibit liver glucose output, such as metformin, insulin sensitizers, etc., before going to bed, and do not consume high-calorie foods, such as milk, oily foods, etc. The specific medication should be combined with clinical practice, and the doctor's face-to-face guidance shall prevail.

Because there are many different hormones in the human body, many hormones have the effect of raising blood sugar, such as glucocorticoids, thyroid hormones, glucagon, etc., and the peak of the secretion of these hormones generally occurs in the early morning to morning, so it is easy to cause blood sugar to rise, which is the so-called "dawn phenomenon".

There are two main conditions when the blood sugar rises in the early morning, if the blood sugar is well controlled at night, there is no hypoglycemia, and the blood sugar is high only for a period of time in the early morning, which is the "dawn phenomenon". To identify the cause of the elevated fasting blood glucose in the early morning, patients may use multiple blood glucose measurements in the middle of the night. It is common practice to test blood glucose at 3 a.m. to determine the presence of hypoglycemia, and then to test your blood glucose in the morning.

If blood sugar does not fall below normal at 3 a.m. and fasting blood sugar rises early in the morning, it is called the "dawn phenomenon".

Elevated fasting blood glucose due to the "dawn phenomenon" can be resolved by adding intermediate-acting insulin before bedtime, adjusting insulin, or taking oral hypoglycemic drugs. It turns out that diabetic patients with "dawn phenomenon" can add subcutaneous injection of intermediate-acting insulin before bedtime on the basis of oral hypoglycemic drugs during the day, which can receive good results and control the phenomenon of high fasting blood sugar in the morning. However, it should be noted that you need to add a bedtime snack before the injection, such as half a glass of milk and two biscuits, to avoid hypoglycemia after insulin injection.

Once fasting blood sugar is satisfactorily controlled in the morning, it is easy to control blood sugar after meals during the day.

However, at the same time, experts also pointed out that when fasting blood sugar rises in the morning, do not easily take hypoglycemic drugs, but should first find out the cause of the increase in fasting blood sugar in the morning, and then adjust the dose of hypoglycemic drugs or insulin under the guidance of specialists to avoid hypoglycemia and life-threatening.

The dawn phenomenon of diabetes is a concept that is often mentioned in diabetes, because in addition to insulin in the human body, it can lower blood sugar and play a role in lowering blood sugar, and the remaining other factors, including thyroid hormone and adrenal hormones, which are hormones that have a strong effect on anti-insulin and have a glycemic effect, including glucagon and so on.

In the early hours of the morning, the hormone secretion of the human body has a regular peak and low peak, mainly at about three o'clock to seven o'clock, there may be a wave of hormone secretion peak. Therefore, in this case, a large amount of hormone secretion will cause an increase in blood sugar, so this situation is called the dawn phenomenon.

In this case, it must be carried out according to its factors, because in the case of insulin resistance, in addition to the increase in hormone secretion, there are also drug factors, or the physiological state factors themselves, and it is still high after correcting the state, and it may be necessary to further adjust the drug intervention.

Drugs used in long-acting or oral medications, or even a fraction of medium- or long-acting insulin injected subcutaneously at bedtime, can still help with this dawn.

There are mainly the following 4 categories that cannot be eaten.

1. First of all, don't eat foods that are too sweet, contain starch, high carbohydrates, and raise blood sugar quickly, such as some starchy foods, and there are rice noodles and rice noodles in Guangdong, which may cause large fluctuations in blood sugar. There are also some patients who like to drink porridge, and they should also pay attention to it, because these are easy to absorb and will cause a rapid rise in blood sugar. In addition, there are also drinks, sugar water, etc., which are mainly based on sugar, and after drinking, blood sugar may rise very significantly, which will cause certain damage to the body.

2. Don't eat too fatty, that is, don't eat high-fat and high-calorie, because these things will cause insulin resistance to the body, increase fat, increase cholesterol, and are also one of the high-risk factors for cardiovascular and cerebrovascular complications.

3. It is not recommended for patients to eat too salty, because too much salt may have a certain relationship with difficult blood pressure control, because it is often said that diabetes and high blood pressure are brothers, and they are often complicated together.

4. There is also the problem of drinking, because some patients still like to drink, and diabetic patients are not recommended to drink too much alcohol. Because drinking alcohol will cause blood sugar fluctuations, increase calorie intake, and drinking alcohol also has a certain damaging effect on the liver.

When some sugar friends monitor their blood sugar, they find that their fasting blood sugar is much higher than that before going to bed when they get up in the morning, and even become the "commanding height" of blood sugar for a day.

This condition is not uncommon in people with diabetes, but the causes vary. The first thing we need to determine is that the basal blood sugar elevation at night caused by hypoglycemic drugs or insufficient insulin at night continues to the early morning hyperglycemia in the early morning. It is also reactive hyperglycemia (somogyi phenomenon) after nocturnal hypoglycemia caused by excessive hypoglycemic agents.

If it doesn't, then this abnormally high fasting blood sugar is the "dawn phenomenon".

"Dawn phenomenon" refers to a state of early morning hyperglycemia caused by the unbalanced secretion of various hormones at dawn in the absence of hypoglycemia in diabetic patients with acceptable and stable blood glucose control at night, that is, without hypoglycemia.

How do you identify the "dawn phenomenon"? In addition to knowing whether you have symptoms of hypoglycemia such as fatigue, palpitations, hunger and sweating, and how to use urine glucose and hypoglycemic agents before bedtime, monitor intravenous or capillary blood glucose every 1 2 hours at night, or monitor night blood glucose with a continuous glucose monitor, and draw a night blood glucose curve based on night blood glucose to make a correct diagnosis.

If you have a dawn phenomenon and do not need to panic, relax, improve and deepen sleep, eat properly, exercise** and seek help from a doctor, choose reasonable hypoglycemic drugs, improve insulin sensitivity, etc., are all conducive to controlling high blood sugar at dawn.

First of all, I would like to introduce you to what the dawn phenomenon is, which refers to the hyperglycemia that occurs at dawn in diabetic patients. In this case, the blood sugar control during the day is quite satisfactory, but the blood sugar is very high every morning.

One possibility is that the medication is not enough at night, or the medication is too early, and the effect of the drug cannot last until the morning, resulting in a gradual increase in blood sugar from 4 o'clock in the morning, which is what we often call the dawn phenomenon. Another possibility is:

Su Mujie reaction, that is, the patient overdoses at night and causes hypoglycemia during sleep, at this time, all the glucose-raising mechanisms are mobilized to avoid shock caused by hypoglycemia, so the blood sugar will rise very high, in short, it is the anti-tone hyperglycemia after hypoglycemia.

These two conditions must be distinguished because the two regimens are opposite, with the former requiring an increase in evening medication and the latter requiring a reduction. The best way to identify this is a series of blood glucose measurements at night.

My advice to you is that you should take a time to measure your blood sugar and collect the corresponding data. The most common test is: before breakfast, 2 hours after breakfast, before lunch, 2 hours after lunch, before dinner, 2 hours after dinner, and 3 o'clock at night.

This will tell you what your mother's blood sugar is during the day and how your blood sugar is at night. If it is normal during the day, but it is high at night or early in the morning, then you have to consider whether there is a dawn phenomenon, and you should measure it every hour or two at night to understand the change in blood sugar at night, so as to distinguish whether it is a dawn reaction or a Su Mujie reaction. The dawn response should be a gradual increase in blood sugar at night, while Su Mujie's reaction is to decrease first and then increase at night.

As for whether the medication is enough, it must be adjusted according to the measured blood sugar level, otherwise it is difficult to say whether the medicine you are using controls blood sugar.

Because you have to test many times, it is recommended that you go to the hospital for inpatient testing, and if you buy a blood glucose meter, you can also test it at home.
