The symptoms of increased heart rate and panic may occur with hunger, and some patients may experience chest tightness. This is actually due to the abnormal secretion of hormones in the body caused by hunger, and the excitement and disorder of the plant nerves. If panic attacks and chest tightness occur when starving, patients must consider whether it is the occurrence of hypoglycemic symptoms, and in most cases, they should monitor their blood sugar in time. If it is found to be hypoglycemia, it should be treated symptomatically and oral sugar cubes or buns should be taken in time to raise blood sugar quickly. When hypoglycemia occurs in patients with diabetes, it is important to consider whether the dosage of hypoglycemic drugs is too high. If the patient is usually undiagnosed with diabetes, it is also important to clarify whether there is the possibility of diabetes or the possibility of insulinoma. In case of recurrent hypoglycemic episodes, the patient must improve islet function and abdominal ultrasound examination.
