What causes large fluctuations in blood sugar?

We all know that the level of blood sugar is not controlled by our personal will. Under normal circumstances, many factors such as diet, exercise, mood and sleep will affect the blood sugar level. When you are in good health, you can keep your blood sugar level within a relatively small range. However, when you suffer from a disease such as diabetes, your blood sugar level will fluctuate greatly.

What causes large fluctuations in blood sugar?

1. Excessive intake of high-fat foods:

This causes the pancreas to not secrete insulin properly, leading to increased blood sugar.

2. Long-term constipation:

It leads to metabolic disorders, poor blood circulation and affects blood sugar.

3. Insufficient drinking water:

Causes metabolic imbalance and affects blood sugar.

4. Climate factors:

Cold stimulation can promote the secretion of adrenaline. The output of liver glycogen increases and the uptake of glucose by muscles decreases, which increases blood sugar and aggravates the condition. In the hot summer, you sweat a lot, so make sure to replenish water, otherwise your blood will become concentrated and your blood sugar will increase.

5. Cold:

A cold can cause blood sugar to rise.

6. Patients suffering from trauma, surgery, infection, fever, severe mental trauma, vomiting, insomnia, anger, anxiety, irritability, fatigue, acute myocardial infarction and other stressful conditions:

It can cause blood sugar to rise rapidly and even induce diabetic ketoacidosis.

7. Insufficient drug dosage:

Some patients reduce the dosage of medication on their own; some do not check their blood sugar for a long time, resulting in failure to adjust the original dosage in time after blood sugar rises. Insufficient drug dosage may cause blood sugar to rise and even ketoacidosis.

8. Sudden changes in working and living environments:

Causes temporary adverse reactions in patients.

Dangers of large blood sugar fluctuations

Short-term impact:

It mainly manifests itself in symptoms such as dizziness, blurred vision, dry mouth, polyuria, etc. Therefore, if the patient's blood sugar is very high at the beginning during hospitalization, the doctor's treatment plan is to gradually and slowly lower the blood sugar. Otherwise, a sudden drop in blood sugar will cause a reaction similar to hypoglycemia, which is medically called reactive hypoglycemia. Therefore, diabetics should not be anxious to lower their blood sugar.

Long-term effects:

It is the occurrence and development of complications, especially closely related to diabetic vascular disease. Studies have shown that high blood sugar fluctuations in the body can cause oxidative stress and promote endothelial cell apoptosis. Endothelial cell damage is a key link in causing vascular disease. Therefore, blood sugar fluctuations promote the occurrence and development of diabetic vascular complications. At the same time, repeatedly fluctuating high-sugar environments are more damaging to the morphology and function of endothelial cells than continuous and stable high sugar environments.
