Hello dear, welcome to Ask a Doctor . I read through the question and understand your concern. I think you are experiencing reactive hypoglycemia that is an early symptom of the prediabetes-related condition known as insulin resistance. Cut the white flour, sugar, and corn syrup out of your diet. Replace these empty calories with nutrient-packed whole grains, lean proteins, beans, nuts, fruits, veggies, and healthy fats, and see what a difference this makes in terms of your energy levels and your low blood sugar symptoms. Also try have more physical activity. Take care. If you have any other question don t hesitate to contact me. Best regards.
