Diabetic patients usually do not show hypoglycemia, but some patients may show hypoglycemia symptoms in the early stage of the attack, and specific analysis is needed for each problem. There are many causes of hypoglycemia, commonly caused by insulinoma, liver failure, heart failure, kidney failure, malnutrition, etc. The diagnosis can usually be confirmed after the completion of relevant examinations. However, some type 2 diabetic patients may have impaired insulin release in the early stage of the disease due to defective perception of glucose stimulation by beta cells in the body, resulting in hyperglycemic symptoms early after meals and reactive hypoglycemia 2-3 hours or 3-5 hours after meals. In addition, diabetic patients may also develop hypoglycemic symptoms during treatment and are recommended to be seen in the endocrinology department. Besides, patients with hypoglycemia need to pay attention to dietary regularity in daily life to avoid corresponding complications. Diabetic patients, on the other hand, are recommended to undergo relevant treatment under the guidance of a doctor.
