What to do if fasting blood sugar is higher than blood sugar after meal

Generally speaking, fasting blood sugar is not as high as blood sugar after meals, but if a diabetic patient has it, the opposite phenomenon is very likely to occur. High fasting blood sugar is very harmful and can easily cause hypoglycemia, dizziness, fatigue, and coma, and requires timely treatment.

1. What to do if fasting blood sugar is high

Normal fasting blood sugar is 3.9-6.1 mmol/L, blood sugar 1 hour after a meal is less than 10.6mmol/L, blood sugar 2 hours after a meal is less than 7.8mmol/L, and blood sugar 3 hours after a meal is less than 7.0mmol/L. It is recommended to control diet, increase physical exercise, and use hypoglycemic drugs scientifically. Patients are advised to consult a diabetes specialist based on the specific condition of the diabetic patient.

2. The hazards of high fasting blood sugar:

1. The most obvious symptom of diabetic patients is that their blood sugar fluctuates and is difficult to stabilize. Due to the instability of blood sugar, the human body's organs are in a state of tension and disorder for a long time, resulting in serious damage to the functions of various organs. More seriously, when blood sugar is too high, it can lead to ketoacidosis; when blood sugar is too low, hypoglycemic shock can occur. These are the fastest, biggest and most difficult to prevent causes of death in people with diabetes!

2. Hypoglycemia: This is a problem that almost every diabetic patient will encounter. When hypoglycemia occurs, everyone feels differently. Mild symptoms include sweating, dizziness, hunger, fatigue, hand tremors, and palpitations. Severe symptoms include numbness of the hands and feet, blurred vision, and even unconsciousness and coma. If not treated in time, death will occur within a very short time.

3. Ketoacidosis: If the blood sugar of a diabetic patient is always fluctuating and cannot be well controlled, the body cannot get the glucose it needs and can only rely on the decomposition of fat to provide energy. However, a large amount of acidic substances are produced in the process of converting fat into energy, resulting in ketoacidosis. The patient will experience nausea, vomiting, difficulty breathing, loss of consciousness, severe dehydration, and coma, leading to death.
