Why did I get blood sugar level over 400 mg/dl after eating?
When eating, we take different amounts of carbohydrates (accordingly to what we eat). These carbohydrates cause a hyperglycemic peak, which is soon neutralized by the release of insulin from the pancreas.
In diabetic people, the insulin production is insufficient, or cells are insensible to insulin. In diabetic people, the aforementioned mechanism is impaired, and the post-prandial hyperglycemia persists.
Glucose builds up in the bloodstream causing complications.
The same as in fasting hyperglycemia including:
- extreme thirst,
- frequent and excess amount of urine,
- fatigue, tiredness,
- blurred vision,
- rapid breathing,
- tingling and numbness of the feet. .
The difference is that they happen few minutes after eating.
The same as described in fasting hyperglycemia.
Rehydration and fast-acting insulin are the chosen treatment, in order to lower blood glucose levels as soon as possible.
Eat small meals several times a day, as scheduled by the doctor.
The same as described in fasting hyperglycemia. Avoid foods rich in carbohydrates and fats is essential.
Patients who have experienced blood sugar level over 400 mg/dl after eating should drink plenty of water, check their urine for ketones and talk to their doctor to take precautions in order to prevent a further increase of the blood sugar level.
The lifestyle changes are also very important.
