Why is my blood sugar still high despite taking insulin?

Insulin is the main drug for the treatment of diabetes. Correct understanding and use of insulin can better control blood sugar and improve the quality of life.

Insulin injection is determined according to blood sugar. When blood sugar is lower than 4.4mmol/L, you should eat immediately after insulin injection, or inject insulin after meal. If you choose not to inject insulin, it will lead to an increase in blood sugar before the next meal, which will directly affect the effect of insulin on controlling blood sugar.

Insulin injection time:

Short-acting insulin - injected 15 minutes before meals

Intermediate-acting insulin - independent of meal time, effective 2-3 hours after injection

Long-acting insulin—scheduled injections in the morning and evening

Premixed insulin - fixed time injection, regular meal

When a person is sick, such as a cold, fever, trauma, etc., the secretion of adrenaline, cortisol, and growth hormone will be stimulated, and the production and decomposition of liver glycogen will lead to an increase in blood sugar.

If the insulin injection is stopped without authorization, it will lead to a sudden rise in blood sugar and even ketoacidosis. Therefore, diabetic patients should adjust the amount of insulin under the guidance of a doctor during their illness, and must not stop insulin injection without authorization.

Too high or too low temperature will affect the therapeutic effect of insulin.

Unopened insulin——store refrigerated at 2°C-8°C. Remember not to freeze and store it, as it will destroy the drug activity of insulin.

Insulin, already opened—keep out of the sun and store at room temperature. Remember to use it up within 4 weeks.

If you want to adjust the insulin dose, you must understand a series of professional issues such as various insulin targets, onset time, peak efficacy, duration of efficacy, blood sugar control target value, etc., without professional medical knowledge and experience in medication It is difficult to master the skills of accumulation.

Some elderly diabetic patients adjust their insulin doses by themselves based on their experience of using insulin for many years and their one-sided knowledge of safe drug use after a long illness.

Therefore, when abnormal blood sugar occurs, it is necessary to follow the doctor's advice and adjust the insulin dose according to the doctor's professional opinion.

The dosage of insulin is not fixed, it is adjusted appropriately according to the condition according to the doctor's advice.

After a period of insulin treatment, the blood sugar level is basically stable, and a fixed injection volume can be maintained.

After the function of pancreatic islet B cells is gradually improved and restored, according to the blood sugar situation, the dosage of insulin can be gradually reduced until the daily required fixed amount.

The daily required fixed amount is a fixed value set according to the blood sugar level, daily diet, daily activity, and emotional stress, and can be increased or decreased appropriately. For example, increased activity today can reduce insulin dosage or increase food intake to avoid hypoglycemia.
