1. Eating too much/too late dinner

If you eat too much dinner the day before, especially if you eat a large amount of high-energy (such as high-fat) food, or eat a late meal or a long-lasting meal (such as dining at a party, etc.), it may lead to an increase in fasting blood sugar.

Countermeasures: Regular and quantitative meals

Diet therapy is the cornerstone of diabetes treatment. People with diabetes should eat scientifically, not only to control the total calories, to match the diet reasonably, but also to eat regularly, and the dinner time should not be too late.

2. Insufficient exercise

If usually exercises regularly, but does not exercise enough the night before, it is likely to cause fasting hyperglycemia.

Countermeasures: Adhere to regular exercise

Exercise therapy is an indispensable basic treatment measure for diabetes treatment. People with diabetes need to keep exercising regularly.If you cannot exercise outdoors due to the weather, you can do some indoor exercises, such as yoga, aerobics, etc., which will also help control blood sugar.

3. Drug factors

If you take less or miss oral hypoglycemic drugs, do not inject enough or even forget to inject insulin, or the insulin injection method is not standardized, these will inevitably lead to the impact of fasting blood sugar levels.

Countermeasures: pay attention to the details of medication

When fasting hyperglycemia occurs. Some elderly people with diabetes have poor memory and are prone to miss taking hypoglycemic drugs or insulin. You can set an alarm clock or ask your family to remind you to take medication on time.

In addition, it is also necessary to pay attention to whether the preservation of insulin is reasonable and whether the injection method of insulin is standardized. The details of these medications may affect the efficacy of the drug and affect blood sugar control.

4. Disease progression

Diabetes is a chronic progressive disease. The prolongation of the course of the disease will inevitably lead to the progression of the disease, the decline of its own islet function, and the insufficient secretion of basal insulin, leading to fasting hyperglycemia.

Countermeasures: adjust the drug treatment plan

If you find that the current treatment cannot effectively control blood sugar, you need to seek help from a doctor in time, and the doctor will adjust the drug treatment plan according to your condition.

It is recommended that you adhere to long-term regular blood sugar monitoring, so as to detect changes in the condition in time, adjust the treatment plan, and avoid or delay the occurrence and development of complications.

5. Dawn phenomenon

The dawn phenomenon refers to: the blood sugar is well controlled before going to bed or at night, and the blood sugar gradually rises at dawn (usually 3 to 8 am), resulting in an increase in fasting blood sugar.

The occurrence of the dawn phenomenon may be related to the gradual increase in the secretion of insulin-resistant hormones (such as glucocorticoids and growth hormones) in the body after midnight.

Countermeasures: Increasing drug doses to combat the dawn phenomenon

In view of the causes of the dawn phenomenon, the dosage of insulin or oral drugs should be increased for such people with diabetes to alleviate the negative effects of insulin-antagonistic hormones, and the effect of the drugs should be maintained until the next morning, so that the fasting blood sugar can reach the target.

6. Somogyi Phenomenon

It is characterized by blood sugar control after dinner or before going to bed, usually due to excessive dosage of hypoglycemic drugs or excessive hunger before dinner or before going to bed, causing nocturnal hypoglycemia (more common in the sleep process at night from 0 to 3 in the morning), A rebound rise in blood sugar ensues.

This rebound hyperglycemia is a protective self-regulation of the human endocrine system to avoid the danger of the body due to continuous hypoglycemia.

Countermeasures: reduce drug dosage, beware of hypoglycemia at night

The treatment method of Somogyi phenomenon is just opposite to that of dawn phenomenon. In order to avoid rebound hyperglycemia caused by nocturnal hypoglycemia, the dosage of hypoglycemic drugs before dinner or before going to bed should be reduced, and an appropriate meal should be added before going to bed.

7. Excessive extra meals

In order to prevent hypoglycemia at night, some sugar lovers need to add meals before going to bed, but if the blood sugar is not low,  adding meals, will inevitably cause fasting blood sugar to rise.

Countermeasures: add meals as appropriate according to blood sugar levels before going to bed

The premise of adding meals before going to bed is that the blood sugar before going to bed is ≤6.0-7.0mmol/L, and the amount of additional meals should not be too large.

In addition, the time to add meals is very important. You should choose to add meals before hypoglycemia occurs, generally around 10 o’clock at night before going to bed; if hypoglycemia occurs and then add meals, you will often eat a lot, which is not conducive to blood sugar control .

8. Poor sleep quality at night

Insomnia or lack of sleep, the sympathetic nerves will be excited, the secretion of catecholamine hormones (such as epinephrine, norepinephrine, etc.) in the body will increase, the sensitivity of the human body to insulin will decrease, and the blood sugar level will increase.

Countermeasures: maintain emotional stability

Everyone should learn to relax, avoid excessive anxiety, and use sedative and hypnotic drugs under the guidance of a doctor if necessary.

When you encounter high fasting blood sugar, you may wish to check yourself against the above situations, and find out the cause before you can deal with it correctly!

If the cause of the elevated fasting blood sugar cannot be determined, it is recommended to seek medical help as soon as possible.

In addition, if you need to adjust the drug treatment plan, you must do so under the guidance of a doctor!
